   * gpg: The commands --full-gen-key and --quick-gen-key now allow
     direct key generation from supported cards.  [#4681]
 
   * gpg: Prepare against chosen-prefix SHA-1 collisions in key
     signatures.  This change removes all SHA-1 based key signature
     newer than 2019-01-19 from the web-of-trust.  Note that this

 Noteworthy changes in version 2.2.17 (2019-07-09)
 -------------------------------------------------
 
   * gpg: Ignore all key-signatures received from keyservers.  This
     change is required to mitigate a DoS due to keys flooded with
     faked key-signatures.  The old behaviour can be achieved by adding
       keyserver-options no-self-sigs-only,no-import-clean
     to your gpg.conf.  [#4607]
 
   * gpg: If an imported keyblocks is too large to be stored in the
     keybox (pubring.kbx) do not error out but fallback to an import
     using the options "self-sigs-only,import-clean".  [#4591]

     refresh keys from the Web Key Directory or via other methods
     configured with --auto-key-locate.

 Noteworthy changes in version 2.2.8 (2018-06-08)
 ------------------------------------------------
 
   * gpg: Decryption of messages not using the MDC mode will now lead
     to a hard failure even if a legacy cipher algorithm was used.  The
     option --ignore-mdc-error can be used to turn this failure into a
     warning.  Take care: Never use that option unconditionally or
     without a prior warning.
 
   * gpg: The MDC encryption mode is now always used regardless of the
     cipher algorithm or any preferences.  For testing --rfc2440 can be
     used to create a message without an MDC.
 
   * gpg: Sanitize the diagnostic output of the original file name in
     verbose mode.  [#4012,CVE-2018-12020]
 
   * gpg: Detect suspicious multiple plaintext packets in a more
     reliable way.  [#4000]
 
   * gpg: Fix the duplicate key signature detection code.  [#3994]
 
   * gpg: The options --no-mdc-warn, --force-mdc, --no-force-mdc,
     --disable-mdc and --no-disable-mdc have no more effect.
 
   * gpg: New command --show-keys.
 
   * agent: Add DBUS_SESSION_BUS_ADDRESS and a few other envvars to the
     list of startup environment variables.  [#3947]

 ------------------------------------------------
 
   * gpg: Fix formatting of the user id in batch mode key generation
     if only "name-email" is given.
 
   * gpgv: Fix annoying "not suitable for" warnings.

   See-also: gnupg-announce/2017q3/000415.html
 
 
 Noteworthy changes in version 2.2.0 (2017-08-28)
 ------------------------------------------------
 
   This is the new long term stable branch.  This branch will only see
   bug fixes and no new features.
 
   * gpg: Reverted change in 2.1.23 so that --no-auto-key-retrieve is
     again the default.
 
   * Fixed a few minor bugs.
 
   See-also: gnupg-announce/2017q3/000413.html
 
 
 Noteworthy changes in version 2.1.23 (2017-08-09)
 -------------------------------------------------
 
   * gpg: "gpg" is now installed as "gpg" and not anymore as "gpg2".
     If needed, the new configure option --enable-gpg-is-gpg2 can be
     used to revert this.
 
   * gpg: Options --auto-key-retrieve and --auto-key-locate "local,wkd"
     are now used by default.  Note: this enables keyserver and Web Key
     Directory operators to notice when a signature from a locally
     non-available key is being verified for the first time or when
     you intend to encrypt to a mail address without having the key
     locally.  This new behaviour will eventually make key discovery
     much easier and mostly automatic.  Disable this by adding
       no-auto-key-retrieve
       auto-key-locate local
     to your gpg.conf.
 
   * agent: Option --no-grab is now the default.  The new option --grab
     allows to revert this.
 
   * gpg: New import option "show-only".
 
   * gpg: New option --disable-dirmngr to entirely disable network
     access for gpg.
 
   * gpg,gpgsm: Tweaked DE-VS compliance behaviour.
 
   * New configure flag --enable-all-tests to run more extensive tests
     during "make check".
 
   * gpgsm: The keygrip is now always printed in colon mode as
     documented in the man page.
 
   * Fixed connection timeout problem under Windows.

 Noteworthy changes in version 2.1.22 (2017-07-28)
 -------------------------------------------------
 
   * gpg: Extend command --quick-set-expire to allow for setting the
     expiration time of subkeys.
 
   * gpg: By default try to repair keys during import.  New sub-option
     no-repair-keys for --import-options.
 
   * gpg,gpgsm: Improved checking and reporting of DE-VS compliance.
 
   * gpg: New options --key-origin and --with-key-origin.  Store the
     time of the last key update from keyservers, WKD, or DANE.
 
   * agent: New option --ssh-fingerprint-digest.
 
   * dimngr: Lower timeouts on keyserver connection attempts and made
     it configurable.
 
   * dirmngr: Tor will now automatically be detected and used.  The
     option --no-use-tor disables Tor detection.
 
   * dirmngr: Now detects a changed /etc/resolv.conf.
 
   * agent,dirmngr: Initiate shutdown on removal of the GnuPG home
     directory.
 
   * gpg: Avoid caching passphrase for failed symmetric encryption.
 
   * agent: Support for unprotected ssh keys.
 
   * dirmngr: Fixed name resolving on systems using only v6
     nameservers.
 
   * dirmngr: Allow the use of TLS over http proxies.
 
   * w32: Change directory of the daemons after startup.
 
   * wks: New man pages for client and server.
 
   * Many other bug fixes.
 
   See-also: gnupg-announce/2017q3/000411.html
 
 
 Noteworthy changes in version 2.1.21 (2017-05-15)
 -------------------------------------------------
 
   * gpg,gpgsm: Fix corruption of old style keyring.gpg files.  This
     bug was introduced with version 2.1.20.  Note that the default
     pubring.kbx format was not affected.
 
   * gpg,dirmngr: Removed the skeleton config file support.  The
     system's standard methods for providing default configuration
     files should be used instead.
 
   * w32: The Windows installer now allows installation of GnuPG
     without Administrator permissions.
 
   * gpg: Fixed import filter property match bug.
 
   * scd: Removed Linux support for Cardman 4040 PCMCIA reader.
 
   * scd: Fixed some corner case bugs in resume/suspend handling.
 
   * Many minor bug fixes and code cleanup.

   * gpg: Changed the key parser to generalize the processing of local
     meta data packets.
 
   * gpg: Fixed assertion failure in the TOFU trust model.
 
   * gpg: Fixed exporting of zero length user ID packets.
 
   * scd: Improved support for multiple readers.
 
   * scd: Fixed timeout handling for key generation.
 
   * agent: New option --enable-extended-key-format.
 
   * dirmngr: Do not add a keyserver to a new dirmngr.conf.  Dirmngr
     uses a default keyserver.
 
   * dimngr: Do not treat TLS warning alerts as severe error when
     building with GNUTLS.
 
   * dirmngr: Actually take /etc/hosts in account.
 
   * wks: Fixed client problems on Windows.  Published keys are now set
     to world-readable.
 
   * tests: Fixed creation of temporary directories.
 
   * A socket directory for a non standard GNUGHOME is now created on
     the fly under /run/user.  Thus "gpgconf --create-socketdir" is now
     optional.  The use of "gpgconf --remove-socketdir" to clean up
     obsolete socket directories is however recommended to avoid
     cluttering /run/user with useless directories.
 
   * Fixed build problems on some platforms.

     only when it is required to watch removal of device/card.
 
   * scd: Improved detection of card inserting and removal.
 
   * dirmngr: New option --disable-ipv4.
 
   * dirmngr: New option --no-use-tor to explicitly disable the use of
     Tor.
 
   * dirmngr: The option --allow-version-check is now required even if
     the option --use-tor is also used.
 
   * dirmngr: Handle a missing nsswitch.conf gracefully.
 
   * dirmngr: Avoid PTR lookups for keyserver pools.  The are only done
     for the debug command "keyserver --hosttable".
 
   * dirmngr: Rework the internal certificate cache to support classes
     of certificates.  Load system provided certificates on startup.
     Add options --tls, --no-crl, and --systrust to the "VALIDATE"
     command.
 
   * dirmngr: Add support for the ntbtls library.
 
   * wks: Create mails with a "WKS-Phase" header.  Fix detection of

 Noteworthy changes in version 2.1.18 (2017-01-23)
 -------------------------------------------------
 
   * gpg: Remove bogus subkey signature while cleaning a key (with
     export-clean, import-clean, or --edit-key's sub-command clean)
 
   * gpg: Allow freezing the clock with --faked-system-time.
 
   * gpg: New --export-option flag "backup", new --import-option flag
     "restore".
 
   * gpg-agent: Fixed long delay due to a regression in the progress
     callback code.
 
   * scd: Lots of code cleanup and internal changes.
 
   * scd: Improved the internal CCID driver.
 
   * dirmngr: Fixed problem with the DNS glue code (removal of the
     trailing dot in domain names).
 
   * dirmngr: Make sure that Tor is actually enabled after changing the
     conf file and sending SIGHUP or "gpgconf --reload dirmngr".
 
   * dirmngr: Fixed Tor access to IPv6 addresses.  Note that current
     versions of Tor may require that the flag "IPv6Traffic" is used
     with the option "SocksPort" in torrc to actually allow IPv6
     traffic.
 
   * dirmngr: Fixed HKP for literally given IPv6 addresses.
 
   * dirmngr: Enabled reverse DNS lookups via Tor.
 
   * dirmngr: Added experimental SRV record lookup for WKD.
     See commit 88dc3af3d4ae1afe1d5e136bc4c38bc4e7d4cd10 for details.
 
   * dirmngr: For HKP use "pgpkey-hkps" and "pgpkey-hkp" in SRV record
     lookups.  Avoid SRV record lookup when a port is explicitly
     specified.  This fixes a regression from the 1.4 and 2.0 behavior.
 
   * dirmngr: Gracefully handle a missing /etc/nsswitch.conf.  Ignore
     negation terms (e.g. "[!UNAVAIL=return]" instead of bailing out.
 
   * dirmngr: Better debug output for flags "dns" and "network".
 
   * dirmngr: On reload mark all known HKP servers alive.
 
   * gpgconf: Allow keyword "all" for --launch, --kill, and --reload.
 
   * tools: gpg-wks-client now ignores a missing policy file on the
     server.
 
   * Avoid unnecessary ambiguity error message in the option parsing.
 
   * Further improvements of the regression test suite.
 
   * Fixed building with --disable-libdns configure option.
 
   * Fixed a crash running the tests on 32 bit architectures.
 
   * Fixed spurious failures on BSD system in the spawn functions.
     This affected for example gpg-wks-client and gpgconf.

  * scd: Support OpenPGP card V3 for RSA.
 
  * dirmngr: Support for the ADNS library has been removed.  Instead
    William Ahern's Libdns is now source included and used on all
    platforms.  This enables Tor support on all platforms.  The new
    option --standard-resolver can be used to disable this code at
    runtime.  In case of build problems the new configure option
    --disable-libdns can be used to build without Libdns.
 
  * dirmngr: Lazily launch ldap reaper thread.
 
  * tools: New options --check and --status-fd for gpg-wks-client.
 
  * The UTF-8 byte order mark is now skipped when reading conf files.
 
  * Fixed many bugs and regressions.

    hope that these tools are written robust enough to accept this new
    algorithm name as well.
 
  * gpgsm: New feature to create certificates from a parameter file.
    Add prompt to the --gen-key UI to create self-signed certificates.

    this was only supported on W32; on non-W32 systems the new
    configure option --disable-standard-socket may now be used to
    disable this new default.
 
  * agent: New and changed passphrases are now created with an
    iteration count requiring about 100ms of CPU work.
 
  * dirmngr: Dirmngr is now a part of this package.  It is now also
    expected to run as a system service and the configuration
    directories are changed to the GnuPG name space. [Update: 2.1.0
    starts dirmngr on demand as user daemon.]
 
  * Support for Windows CE. [Update: This has not been tested for the
    2.1.0 release]
 
  * Numerical values may now be used as an alternative to the
    debug-level keywords.

 Noteworthy changes in version 2.0.3 (2007-03-08)
 ------------------------------------------------
 
  * By default, do not allow processing multiple plaintexts in a single
    stream.  Many programs that called GnuPG were assuming that GnuPG
    did not permit this, and were thus not using the plaintext boundary
    status tags that GnuPG provides.  This change makes GnuPG reject
    such messages by default which makes those programs safe again.
    --allow-multiple-messages returns to the old behavior. [CVE-2007-1263].
 
  * New --verify-option show-primary-uid-only.
 
  * gpgconf may now reads a global configuration file to select which
    options are changeable by a frontend.  The new applygnupgdefaults

    packages. [CVE-2006-6235].
 
  * Added --passphrase-repeat to set the number of times GPG will
    prompt for a new passphrase to be repeated.  This is useful to help
    memorize a new passphrase.  The default is 1 repetition.
 
  * Using a PIN pad does now also work for the signing key.
 
  * A warning is displayed by gpg-agent if a new passphrase is too
    short.  New option --min-passphrase-len defaults to 8.
 
  * The status code BEGIN_SIGNING now shows the used hash algorithms.

    Texinfo source.
 
  * The gpg code from 1.4.5 has been fully merged into this release.
    The configure option --enable-gpg is still required to build this
    gpg part.  For production use of OpenPGP the gpg version 1.4.5 is
    still recommended.  Note, that gpg will be installed under the name

  * gpg-connect-agent has now features to handle Assuan INQUIRE
    commands.
 
  * Internal changes for OpenPGP cards. New Assuan command WRITEKEY.
 
  * GNU Pth is now a hard requirement.
 
  * [scdaemon] Support for OpenSC has been removed.  Instead a new and
    straightforward pkcs#15 modules has been written.  As of now it
    does allows only signing using TCOS cards but we are going to
    enhance it to match all the old capabilities.
 
  * [gpg-agent] New option --write-env-file and Assuan command
    UPDATESTARTUPTTY.
 
  * [gpg-agent] New option --default-cache-ttl-ssh to set the TTL for
    SSH passphrase caching independent from the other passphrases.
 
 
 Noteworthy changes in version 1.9.16 (2005-04-21)
 -------------------------------------------------
 
  * gpg-agent does now support the ssh-agent protocol and thus allows
    to use the pinentry as well as the OpenPGP smartcard with ssh.
 
  * New tool gpg-connect-agent as a general client for the gpg-agent.
 
  * New tool symcryptrun as a wrapper for certain encryption tools.
 
  * The gpg tool is not anymore build by default because those gpg
    versions available in the gnupg 1.4 series are far more matured.
 
 
 Noteworthy changes in version 1.9.15 (2005-01-13)
 -------------------------------------------------
 
  * Fixed passphrase caching bug.
 
  * Better support for CCID readers; the reader from Cherry RS 6700 USB
    does now work.
 
 
 Noteworthy changes in version 1.9.14 (2004-12-22)
 -------------------------------------------------
 
  * [gpg-agent] New option --use-standard-socket to allow the use of a
    fixed socket.  gpgsm falls back to this socket if GPG_AGENT_INFO
    has not been set.
 
  * Ported to MS Windows with some functional limitations.
 
  * New tool gpg-preset-passphrase.
 
 
 Noteworthy changes in version 1.9.13 (2004-12-03)
 -------------------------------------------------
 
  * [gpgsm] New option --prefer-system-dirmngr.
 
  * Minor cleanups and debugging aids.
 
 
 Noteworthy changes in version 1.9.12 (2004-10-22)
 -------------------------------------------------
 
  * [scdaemon] Partly rewrote the PC/SC code.
 
  * Removed the sc-investigate tool.  It is now in a separate package
    available at ftp://ftp.g10code.com/g10code/gscutils/ .
 
  * [gpg-agent] Fixed logging problem.
 
 
 Noteworthy changes in version 1.9.11 (2004-10-01)
 -------------------------------------------------
 
  * When using --import along with --with-validation, the imported
    certificates are validated and only imported if they are fully
    valid.
 
  * [gpg-agent] New option --max-cache-ttl.
 
  * [gpg-agent] When used without --daemon or --server, gpg-agent now
    check whether a agent is already running and usable.
 
  * Fixed some i18n problems.
 
 
 Noteworthy changes in version 1.9.10 (2004-07-22)
 -------------------------------------------------
 
  * Fixed a serious bug in the checking of trusted root certificates.
 
  * New configure option --enable-agent-pnly allows to build and
    install just the agent.
 
  * Fixed a problem with the log file handling.
 
 
 Noteworthy changes in version 1.9.9 (2004-06-08)
 ------------------------------------------------
 
  * [gpg-agent] The new option --allow-mark-trusted is now required to
    allow gpg-agent to add a key to the trustlist.txt after user
    confirmation.
 
  * Creating PKCS#10 requests does now honor the key usage.
 
 
 Noteworthy changes in version 1.9.8 (2004-04-29)
 ------------------------------------------------
 
  * [scdaemon] Overhauled the internal CCID driver.
 
  * [scdaemon] Status files named ~/.gnupg/reader_<n>.status are now
    written when using the internal CCID driver.
 
  * [gpgsm] New commands --dump-{,secret,external}-keys to show a very
    detailed view of the certificates.
 
  * The keybox gets now compressed after 3 hours and ephemeral
    stored certificates are deleted after about a day.
 
  * [gpg] Usability fixes for --card-edit.  Note, that this has already
    been ported back to gnupg-1.3
 
 
 Noteworthy changes in version 1.9.7 (2004-04-06)
 ------------------------------------------------
 
  * Instrumented the modules for gpgconf.
 
  * Added support for DINSIG card applications.
 
  * Include the smimeCapabilities attribute with signed messages.
 
  * Now uses the gettext domain "gnupg2" to avoid conflicts with gnupg
    versions < 1.9.
 
 
 Noteworthy changes in version 1.9.6 (2004-03-06)
 ------------------------------------------------
 
  * Code cleanups and bug fixes.
 
 
 Noteworthy changes in version 1.9.5 (2004-02-21)
 ------------------------------------------------
 
  * gpg-protect-tool gets now installed into libexec as it ought to be.
    Cleaned up the build system to better comply with the coding
    standards.
 
  * [gpgsm] The --import command is now able to autodetect pkcs#12
    files and import secret and private keys from this file format.
    A new command --export-secret-key-p12 is provided to allow
    exporting of secret keys in PKCS\#12 format.
 
  * [gpgsm] The pinentry will now present a description of the key for
    whom the passphrase is requested.
 
  * [gpgsm] New option --with-validation to check the validity of key
    while listing it.
 
  * New option --debug-level={none,basic,advanced,expert,guru} to map
    the debug flags to sensitive levels on a per program base.
 
 
 Noteworthy changes in version 1.9.4 (2004-01-30)
 ------------------------------------------------
 
  * Added support for the Telesec NKS 2.0 card application.
 
  * Added simple tool addgnupghome to create .gnupg directories from
    /etc/skel/.gnupg.
 
  * Various minor bug fixes and cleanups; mainly gpgsm and gpg-agent
    related.
 
 
 Noteworthy changes in version 1.9.3 (2003-12-23)
 ------------------------------------------------
 
  * New gpgsm options --{enable,disable}-ocsp to validate keys using
    OCSP. This option requires a not yet released DirMngr version.
    Default is disabled.
 
  * The --log-file option may now be used to print logs to a socket.
    Prefix the socket name with "socket://" to enable this.  This does
    not work on all systems and falls back to stderr if there is a
    problem with the socket.
 
  * The options --encrypt-to and --no-encrypt-to now work the same in
    gpgsm as in gpg.  Note, they are also used in server mode.
 
  * Duplicated recipients are now silently removed in gpgsm.
 
 
 Noteworthy changes in version 1.9.2 (2003-11-17)
 ------------------------------------------------
 
  * On card key generation is no longer done using the --gen-key
    command but from the menu provided by the new --card-edit command.
 
  * PINs are now properly cached and there are only 2 PINs visible.
    The 3rd PIN (CHV2) is internally synchronized with the regular PIN.
 
  * All kind of other internal stuff.
 
 
 Noteworthy changes in version 1.9.1 (2003-09-06)
 ------------------------------------------------
 
  * Support for OpenSC is back. scdaemon supports a --disable-opensc to
    disable OpenSC use at runtime, so that PC/SC or ct-API can still be
    used directly.
 
  * Rudimentary support for the SCR335 smartcard reader using an
    internal driver.  Requires current libusb from CVS.
 
  * Bug fixes.
 
 
 Noteworthy changes in version 1.9.0 (2003-08-05)
 ------------------------------------------------
 
       ====== PLEASE SEE README-alpha =======
 
  * gpg has been renamed to gpg2 and gpgv to gpgv2.  This is a
    temporary change to allow co-existing with stable gpg versions.
 
  * ~/.gnupg/gpg.conf-1.9.0 is fist tried as config file before the
    usual gpg.conf.
 
  * Removed the -k, -kv and -kvv commands.  -k is now an alias to
    --list-keys.  New command -K as alias for --list-secret-keys.
 
  * Removed --run-as-shm-coprocess feature.
 
  * gpg does now also use libgcrypt, libgpg-error is required.
 
  * New gpgsm commands --call-dirmngr and --call-protect-tool.
 
  * Changing a passphrase is now possible using "gpgsm --passwd"
 
  * The content-type attribute is now recognized and created.
 
  * The agent does now reread certain options on receiving a HUP.
 
  * The pinentry is now forked for each request so that clients with
    different environments are supported.  When running in daemon mode
    and --keep-display is not used the DISPLAY variable is ignored.
 
  * Merged stuff from the newpg branch and started this new
    development branch.

 Version 1.4.0 (2004-12-16)
 
 
 Noteworthy changes in version 1.3.2 (2003-05-27)
 ------------------------------------------------
 
     * New "--gnupg" option (set by default) that disables --openpgp,
       and the various --pgpX emulation options.  This replaces
       --no-openpgp, and --no-pgpX, and also means that GnuPG has
       finally grown a --gnupg option to make GnuPG act like GnuPG.
 
     * A bug in key validation has been fixed.  This bug only affects
       keys with more than one user ID (photo IDs do not count here),
       and results in all user IDs on a given key being treated with
       the validity of the most-valid user ID on that key.
 
     * Notation names that do not contain a '@' are no longer allowed
       unless --expert is set.  This is to help prevent pollution of
       the (as yet unused) IETF notation namespace.
 
     * Multiple trust models are now supported via the --trust-model
       option.  The options are "pgp" (web-of-trust plus trust
       signatures), "classic" (web-of-trust only), and "always"
       (identical to the --always-trust option).
 
     * The --personal-{cipher|digest|compression}-preferences are now
       consulted to get default algorithms before resorting to the
       last-ditch defaults of --s2k-cipher-algo, SHA1, and ZIP
       respectively.  This allows a user to set algorithms to use in a
       safe manner so they are used when legal to do so, without
       forcing them on for all messages.
 
     * New --primary-keyring option to designate the keyring that the
       user wants new keys imported into.
 
     * --s2k-digest-algo is now used for all password mangling.
       Earlier versions used both --s2k-digest-algo and --digest-algo
       for passphrase mangling.
 
     * Handling of --hidden-recipient or --throw-keyid messages is now
       easier - the user only needs to give their passphrase once, and
       GnuPG will try it against all of the available secret keys.
 
     * Care is taken to prevent compiler optimization from removing
       memory wiping code.
 
     * New option --no-mangle-dos-filenames so that filenames are not
       truncated in the W32 version.
 
     * A "convert-from-106" script has been added.  This is a simple
       script that automates the conversion from a 1.0.6 or earlier
       version of GnuPG to a 1.0.7 or later version.
 
     * Disabled keys are now skipped when selecting keys for
       encryption.  If you are using the --with-colons key listings to
       detect disabled keys, please see doc/DETAILS for a minor format
       change in this release.
 
     * Minor trustdb changes to make the trust calculations match
       common usage.
 
     * New command "revuid" in the --edit-key menu to revoke a user ID.
       This is a simpler interface to the old method (which still
       works) of revoking the user ID self-signature.
 
     * Status VALIDSIG does now also print the primary key's
       fingerprint, as well as the signature version, pubkey algorithm,
       hash algorithm, and signature class.
 
     * Add read-only support for the SHA-256 hash, and optional
       read-only support for the SHA-384 and SHA-512 hashes.
 
     * New option --enable-progress-filter for use with frontends.
 
     * DNS SRV records are used in HKP keyserver lookups to allow
       administrators to load balance and select keyserver ports
       automatically.  This is as specified in
       draft-shaw-openpgp-hkp-00.txt.
 
     * When using the "keyid!" syntax during a key export, only that
       specified key is exported.  If the key in question is a subkey,
       the primary key plus only that subkey is exported.
 
     * configure --disable-xxx options to disable individual algorithms
       at build time.  This can be used to build a smaller gpg binary
       for embedded uses where space is tight.  See the README file for
       the algorithms that can be used with this option, or use
       --enable-minimal to build the smallest gpg possible (disables
       all optional algorithms, disables keyserver access, and disables
       photo IDs).
 
     * The keyserver no-modify flag on a key can now be displayed and
       modified.
 
     * Note that the TIGER/192 digest algorithm is in the process of
       being dropped from the OpenPGP standard.  While this release of
       GnuPG still contains it, it is disabled by default.  To ensure
       you will still be able to use your messages with future versions
       of GnuPG and other OpenPGP programs, please do not use this
       algorithm.

 Noteworthy changes in version 1.3.1 (2002-11-12)
 ------------------------------------------------
 
     * Trust signature support.  This is based on the Maurer trust
       model where a user can specify the trust level along with the
       signature with multiple levels so users can delegate
       certification ability to other users, possibly restricted by a
       regular expression on the user ID.  Note that full trust
       signature support requires a regular expression parsing library.
       The regexp code from glibc 2.3.1 is included for those platforms
       that don't have working regexp functions available.  The
       configure option --disable-regex may be used to disable any
       regular expression code, which will make GnuPG ignore any trust
       signature with a regular expression included.
 
     * Two new commands --hidden-recipient (-R) and --hidden-encrypt-to
       encrypt to a user, but hide the identity of that user.  This is
       the same functionality as --throw-keyid, but can be used on a
       per-user basis.
 
     * Full algorithm names (e.g. "3DES", "SHA1", "ZIP") can now be
       used interchangeably with the short algorithm names (e.g. "S2",
       "H2", "Z1") anywhere algorithm names are used in GnuPG.
 
 
 Noteworthy changes in version 1.3.0 (2002-10-18)
 ------------------------------------------------
 
     * The last piece of internal keyserver support has been removed,
       and now all keyserver access is done via the keyserver plugins.
       There is also a newer keyserver protocol used between GnuPG and
       the plugins, so plugins from earlier versions of GnuPG may not
       work properly.
 
     * The HKP keyserver plugin supports the new machine-readable key
       listing format for those keyservers that provide it.
 
     * When using a HKP keyserver with multiple DNS records (such as
       wwwkeys.pgp.net which has the addresses of multiple servers
       around the world), try all records until one succeeds.  Note
       that it depends on the LDAP library used whether the LDAP
       keyserver plugin does this as well.
 
     * The library dependencies for OpenLDAP seem to change fairly
       frequently, and GnuPG's configure script cannot guess all the
       combinations.  Use ./configure LDAPLIBS="-L libdir -l libs" to
       override the script and use the libraries selected.
 
     * Secret keys generated with --export-secret-subkeys are now
       indicated in key listings with a '#' after the "sec", and in
       --with-colons listings by showing no capabilities (no lowercase
       characters).
 
     * --trusted-key has been un-obsoleted, as it is useful for adding
       ultimately trusted keys from the config file.  It is identical
       to using --edit and "trust" to change a key to ultimately
       trusted.
 
     * Translations other than de are no longer distributed with the
       development branch.  This is due to the frequent text changes
       during development, which cause the translations to rapidly go
       out of date.

 Version 1.2.2 (2003-05-01)
 Version 1.2.1 (2002-10-25)
 Version 1.2.0 (2002-09-21)
 
 
 Noteworthy changes in version 1.1.92 (2002-09-11)
 -------------------------------------------------
 
     * [IMPORTANT] The default configuration file is now
       ~/.gnupg/gpg.conf.  If an old ~/.gnupg/options is found it will
       still be used.  This change is required to have a more
       consistent naming scheme with forthcoming tools.
 
     * The use of MDCs have increased.  A MDC will be used if the
       recipients directly request it, if the recipients have AES,
       AES192, AES256, or TWOFISH in their cipher preferences, or if
       the chosen cipher has a blocksize not equal to 64 bits
       (currently this is also AES, AES192, AES256, and TWOFISH).
 
     * GnuPG will no longer automatically disable compression when
       processing an already-compressed file unless a MDC is being
       used.  This is to give the message a certain amount of
       resistance to the chosen-ciphertext attack while communicating
       with other programs (most commonly PGP earlier than version 7.x)
       that do not support MDCs.
 
     * The option --interactive now has the desired effect when
       importing keys.
 
     * The file permission and ownership checks on files have been
       clarified.  Specifically, the homedir (usually ~/.gnupg) is
       checked to protect everything within it.  If the user specifies
       keyrings outside this homedir, they are presumed to be shared
       keyrings and therefore *not* checked.  Configuration files
       specified with the --options option and the IDEA cipher
       extension specified with --load-extension are checked, along
       with their enclosing directories.
 
     * The configure option --with-static-rnd=auto allows to build gpg
       with all available entropy gathering modules included.  At
       runtime the best usable one will be selected from the list
       linux, egd, unix.  This is also the default for systems lacking
       a /dev/random device.
 
     * The default character set is now taken from the current locale;
       it can still be overridden by the --charset option.  Using the
       option -vvv shows the used character set.
 
     * [REMOVED] --emulate-checksum-bug and --emulate-3des-s2k-bug have
       been removed.
 
 
 Noteworthy changes in version 1.1.91 (2002-08-04)
 -------------------------------------------------
 
     * All modules are now linked statically; the --load-extension
       option is in general not useful anymore.  The only exception is
       to specify the deprecated idea cipher.
 
     * The IDEA plugin has changed.  Previous versions of the IDEA
       plugin will no longer work with GnuPG.  However, the current
       version of the plugin will work with earlier GnuPG versions.
 
     * When using --batch with one of the --delete-key commands, the
       key must be specified by fingerprint.  See the man page for
       details.
 
     * There are now various ways to restrict the ability GnuPG has to
       exec external programs (for the keyserver helpers or photo ID
       viewers).  Read the README file for the complete list.
 
     * New export option to leave off attribute packets (photo IDs)
       during export.  This is useful when exporting to HKP keyservers
       which do not understand attribute packets.
 
     * New import option to repair during import the HKP keyserver
       mangling multiple subkeys bug.  Note that this cannot completely
       repair the damaged key as some crucial data is removed by the
       keyserver, but it does at least give you back one subkey.  This
       is on by default for keyserver --recv-keys, and off by default
       for regular --import.
 
     * The keyserver helper programs now live in
       /usr/[local/]libexec/gnupg by default.  If you are upgrading
       from 1.0.7, you might want to delete your old copies in
       /usr/[local/]bin.  If you use an OS that does not use libexec
       for whatever reason, use configure --libexecdir=/usr/local/lib
       to place the keyserver helpers there.
 
     * The LDAP keyserver handler now works properly with very old
       (version 1) LDAP keyservers.
 
 
 Noteworthy changes in version 1.1.90 (2002-07-01)
 -------------------------------------------------
 
     * New commands: --personal-cipher-preferences,
       --personal-digest-preferences, and
       --personal-compress-preferences allow the user to specify which
       algorithms are to be preferred.  Note that this does not permit
       using an algorithm that is not present in the recipient's
       preferences (which would violate the OpenPGP standard).  This
       just allows sorting the preferences differently.
 
     * New "group" command to refer to several keys with one name.
 
     * A warning is issued if the user forces the use of an algorithm
       that is not listed in the recipient's preferences.
 
     * Full revocation key (aka "designated revoker") support.
 
     * The preferred hash algorithms on a key are consulted when
       encrypting a signed message to that key.  Note that this is
       disabled by default by a SHA1 preference in
       --personal-digest-preferences.
 
     * --cert-digest-algo allows the user to specify the hash algorithm
       to use when signing a key rather than the default SHA1 (or MD5
       for PGP2 keys).  Do not use this feature unless you fully
       understand the implications of this.
 
     * --pgp7 mode automatically sets all necessary options to ensure
       that the resulting message will be usable by a user of PGP 7.x.
 
     * New --attribute-fd command for frontends and scripts to get the
       contents of attribute packets (i.e. photos)
 
     * In expert mode, the user can now re-sign a v3 key with a v4
       self-signature.  This does not change the v3 key into a v4 key,
       but it does allow the user to use preferences, primary ID flags,
       etc.
 
     * Significantly improved photo ID support on non-unixlike
       platforms.
 
     * The version number has jumped ahead to 1.1.90 to skip over the
       old version 1.1 and to get ready for the upcoming 1.2.
 
     * ElGamal sign and encrypt is not anymore allowed in the key
       generation dialog unless in expert mode.  RSA sign and encrypt
       has been added with the same restrictions.
 
     * [W32] Keyserver access does work with Windows NT.
 
 
 Noteworthy changes in version 1.0.7 (2002-04-29)
 ------------------------------------------------
 
     * Secret keys are now stored and exported in a new format which
       uses SHA-1 for integrity checks.  This format renders the
       Rosa/Klima attack useless.  Other OpenPGP implementations might
       not yet support this, so the option --simple-sk-checksum creates
       the old vulnerable format.
 
     * The default cipher algorithm for encryption is now CAST5,
       default hash algorithm is SHA-1.  This will give us better
       interoperability with other OpenPGP implementations.
 
     * Symmetric encrypted messages now use a fixed file size if
       possible.  This is a tradeoff: it breaks PGP 5, but fixes PGP 2,
       6, and 7.  Note this was only an issue with RFC-1991 style
       symmetric messages.
 
     * Photographic user ID support.  This uses an external program to
       view the images.
 
     * Enhanced keyserver support via keyserver "plugins".  GnuPG comes
       with plugins for the NAI LDAP keyserver as well as the HKP email
       keyserver.  It retains internal support for the HKP HTTP
       keyserver.
 
     * Nonrevocable signatures are now supported.  If a user signs a
       key nonrevocably, this signature cannot be taken back so be
       careful!
 
     * Multiple signature classes are usable when signing a key to
       specify how carefully the key information (fingerprint, photo
       ID, etc) was checked.
 
     * --pgp2 mode automatically sets all necessary options to ensure
       that the resulting message will be usable by a user of PGP 2.x.
 
     * --pgp6 mode automatically sets all necessary options to ensure
       that the resulting message will be usable by a user of PGP 6.x.
 
     * Signatures may now be given an expiration date.  When signing a
       key with an expiration date, the user is prompted whether they
       want their signature to expire at the same time.
 
     * Revocation keys (designated revokers) are now supported if
       present.  There is currently no way to designate new keys as
       designated revokers.
 
     * Permissions on the .gnupg directory and its files are checked
       for safety.
 
     * --expert mode enables certain silly things such as signing a
       revoked user id, expired key, or revoked key.
 
     * Some fixes to build cleanly under Cygwin32.
 
     * New tool gpgsplit to split OpenPGP data formats into packets.
 
     * New option --preserve-permissions.
 
     * Subkeys created in the future are not used for encryption or
       signing unless the new option --ignore-valid-from is used.
 
     * Revoked user-IDs are not listed unless signatures are listed too
       or we are in verbose mode.
 
     * There is no default comment string with ascii armors anymore
       except for revocation certificates and --enarmor mode.
 
     * The command "primary" in the edit menu can be used to change the
       primary UID, "setpref" and "updpref" can be used to change the
       preferences.
 
     * Fixed the preference handling; since 1.0.5 they were erroneously
       matched against against the latest user ID and not the given one.
 
     * RSA key generation.
 
     * Merged Stefan's patches for RISC OS in.  See comments in
       scripts/build-riscos.
 
     * It is now possible to sign and conventional encrypt a message (-cs).
 
     * The MDC feature flag is supported and can be set by using
       the "updpref" edit command.
 
     * The status messages GOODSIG and BADSIG are now returning the primary
       UID, encoded using %XX escaping (but with spaces left as spaces,
       so that it should not break too much)
 
     * Support for GDBM based keyrings has been removed.
 
     * The entire keyring management has been revamped.
 
     * The way signature stati are store has changed so that v3
       signatures can be supported. To increase the speed of many
       operations for existing keyrings you can use the new
       --rebuild-keydb-caches command.
 
     * The entire key validation process (trustdb) has been revamped.
       See the man page entries for --update-trustdb, --check-trustdb
       and --no-auto-check-trustdb.
 
     * --trusted-keys is again obsolete, --edit can be used to set the
       ownertrust of any key to ultimately trusted.
 
     * A subkey is never used to sign keys.
 
     * Read only keyrings are now handled as expected.
 
     See-also: gnupg-announce/2002q2/000135.html
 
 
 Noteworthy changes in version 1.0.6 (2001-05-29)
 ------------------------------------------------
 
     * Security fix for a format string bug in the tty code.
 
     * Fixed format string bugs in all PO files.
 
     * Removed Russian translation due to too many bugs.  The FTP
       server has an unofficial but better translation in the contrib
       directory.
 
     * Fixed expire time calculation and keyserver access.
 
     * The usual set of minor bug fixes and enhancements.
 
     * non-writable keyrings are now correctly handled.
 
     See-also: gnupg-announce/2001q2/000123.html
 
 
 Noteworthy changes in version 1.0.5 (2001-04-29)
 ------------------------------------------------
 
     * WARNING: The semantics of --verify have changed to address a
       problem with detached signature detection. --verify now ignores
       signed material given on stdin unless this is requested by using
       a "-" as the name for the file with the signed material.  Please
       check all your detached signature handling applications and make
       sure that they don't pipe the signed material to stdin without
       using a filename together with "-" on the the command line.
 
     * WARNING: Corrected hash calculation for input data larger than
       512M - it was just wrong, so you might notice bad signature in
       some very big files.  It may be wise to keep an old copy of
       GnuPG around.
 
     * Secret keys are no longer imported unless you use the new option
       --allow-secret-key-import.  This is a kludge and future versions will
       handle it in another way.
 
     * New command "showpref" in the --edit-key menu to show an easier
       to understand preference listing.
 
     * There is now the notation of a primary user ID.  For example, it
       is printed with a signature verification as the first user ID;
       revoked user IDs are not printed there anymore.  In general the
       primary user ID is the one with the latest self-signature.
 
     * New --charset=utf-8 to bypass all internal conversions.
 
     * Large File Support (LFS) is now working.
 
     * New options: --ignore-crc-error, --no-sig-create-check,
       --no-sig-cache, --fixed-list-mode, --no-expensive-trust-checks,
       --enable-special-filenames and --use-agent.  See man page.
 
     * New command --pipemode, which can be used to run gpg as a
       co-process.  Currently only the verification of detached
       signatures are working.  See doc/DETAILS.
 
     * Keyserver support for the W32 version.
 
     * Rewritten key selection code so that GnuPG can better cope with
       multiple subkeys, expire dates and so.  The drawback is that it
       is slower.
 
     * A whole lot of bug fixes.
 
     * The verification status of self-signatures are now cached. To
       increase the speed of key list operations for existing keys you
       can do the following in your GnuPG homedir (~/.gnupg):
          cp pubring.gpg pubring.gpg.save && gpg --export-all >x && \
          rm pubring.gpg && gpg --import x
       Only v4 keys (i.e not the old RSA keys) benefit from this caching.
 
     * New translations: Estonian, Turkish.
 
     See-also: gnupg-announce/2001q2/000122.html
 
 
 Noteworthy changes in version 1.0.4 (2000-10-17)
 ------------------------------------------------
 
     * Fixed a serious bug which could lead to false signature verification
       results when more than one signature is fed to gpg.  This is the
       primary reason for releasing this version.
 
     * New utility gpgv which is a stripped down version of gpg to
       be used to verify signatures against a list of trusted keys.
 
     * Rijndael (AES) is now supported and listed with top preference.
 
     * --with-colons now works with --print-md[s].
 
     See-also: gnupg-announce/2000q4/000082.html
 
 
 Noteworthy changes in version 1.0.3 (2000-09-18)
 ------------------------------------------------
 
     * Fixed problems with piping to/from other MS-Windows software
 
     * Expiration time of the primary key can be changed again.
 
     * Revoked user IDs are now marked in the output of --list-key
 
     * New options --show-session-key and --override-session-key
       to help the British folks to somewhat minimize the danger
       of this Orwellian RIP bill.
 
     * New options --merge-only and --try-all-secrets.
 
     * New configuration option --with-egd-socket.
 
     * The --trusted-key option is back after it left us with 0.9.5
 
     * RSA is supported. Key generation does not yet work but will come
       soon.
 
     * CAST5 and SHA-1 are now the default algorithms to protect the key
       and for symmetric-only encryption. This should solve a couple
       of compatibility problems because the old algorithms are optional
       according to RFC2440
 
     * Twofish and MDC enhanced encryption is now used.  PGP 7 supports
       this.  Older versions of GnuPG don't support it, so they should be
       upgraded to at least 1.0.2
 
     See-also: gnupg-announce/2000q3/000075.html
 
 
 Noteworthy changes in version 1.0.2 (2000-07-12)
 ----------------------------------------------
 
     * Fixed expiration handling of encryption keys.
 
     * Add an experimental feature to do unattended key generation.
 
     * The user is now asked for the reason of revocation as required
       by the new OpenPGP draft.
 
     * There is a ~/.gnupg/random_seed file now which saves the
       state of the internal RNG and increases system performance
       somewhat.  This way the full entropy source is only used in
       cases were it is really required.
       Use the option --no-random-seed-file to disable this feature.
 
     * New options --ignore-time-conflict and --lock-never.
 
     * Some fixes for the W32 version.
 
     * The entropy.dll is not anymore used by the W32 version but replaced
       by code derived from Cryptlib.
 
     * Encryption is now much faster: About 2 times for 1k bit keys
       and 8 times for 4k keys.
 
     * New encryption keys are generated in a way which allows a much
       faster decryption.
 
     * New command --export-secret-subkeys which outputs the
       the _primary_ key with it's secret parts deleted.  This is
       useful for automated decryption/signature creation as it
       allows to keep the real secret primary key offline and
       thereby protecting the key certificates and allowing to
       create revocations for the subkeys.  See the FAQ for a
       procedure to install such secret keys.
 
     * Keygeneration now writes to the first writeable keyring or
       as default to the one in the homedirectory.  Prior versions
       ignored all --keyring options.
 
     * New option --command-fd to take user input from a file descriptor;
       to be used with --status-fd by software which uses GnuPG as a backend.
 
     * There is a new status PROGRESS which is used to show progress during
       key generation.
 
     * Support for the new MDC encryption packets.  To create them either
       --force-mdc must be use or cipher algorithm with a blocksize other
       than 64 bits is to be used.  --openpgp currently disables MDC packets
       entirely.  This option should not yet be used.
 
     * New option --no-auto-key-retrieve to disable retrieving of
       a missing public key from a keyserver, when a keyserver has been set.
 
     * Danish translation
 
     See-also: gnupg-announce/2000q3/000069.html
 
 
 Noteworthy changes in version 1.0.1 (1999-12-16)
 -----------------------------------
 
     * New command --verify-files.  New option --fast-list-mode.
 
     * $http_proxy is now used when --honor-http-proxy is set.
 
     * Fixed some minor bugs and the problem with conventional encrypted
       packets which did use the gpg v3 partial length headers.
 
     * Add Indonesian and Portugese translations.
 
     * Fixed a bug with symmetric-only encryption using the non-default 3DES.
       The option --emulate-3des-s2k-bug may be used to decrypt documents
       which have been encrypted this way; this should be done immediately
       as this workaround will be remove in 1.1
 
     * Can now handle (but not display) PGP's photo IDs. I don't know the
       format of that packet but after stripping a few bytes from the start
       it looks like a JPEG (at least my test data).  Handling of this
       package is required because otherwise it would mix up the
       self signatures and you can't import those keys.
 
     * Passing non-ascii user IDs on the commandline should now work in all
       cases.
 
     * New keys are now generated with an additional preference to Blowfish.
 
     * Removed the GNU Privacy Handbook from the distribution as it will go
       into a separate one.
 
     See-also: gnupg-announce/1999q4/000050.html
 
 
 Noteworthy changes in version 1.0.0 (1999-09-07)
 -----------------------------------
 
     * Add a very preliminary version of the GNU Privacy Handbook to
       the distribution (lynx doc/gph/index.html).
 
     * Changed the version number to GnuPG 2001 ;-)
 
     See-also: gnupg-announce/1999q3/000037.html
 
 
 Noteworthy changes in version 0.9.11 (1999-09-03)
 ------------------------------------
 
     * UTF-8 strings are now correctly printed (if --charset is set correctly).
       Output of --with-colons remains C-style escaped UTF-8.
 
     * Workaround for a problem with PGP 5 detached signature in textmode.
 
     * Fixed a problem when importing new subkeys (duplicated signatures).
 
     See-also: gnupg-announce/1999q3/000036.html
 
 
 Noteworthy changes in version 0.9.10 (1999-07-23)
 ------------------------------------
 
     * Some strange new options to help pgpgpg
 
     * Cleaned up the dox a bit.
 
     See-also: gnupg-announce/1999q3/000034.html
 
 
 Noteworthy changes in version 0.9.9
 -----------------------------------
 
     * New options --[no-]utf8-strings.
 
     * New edit-menu commands "enable" and "disable" for entire keys.
 
     * You will be asked for a filename if gpg cannot deduce one.
 
     * Changes to support libtool which is needed for the development
       of libgcrypt.
 
     * New script tools/lspgpot to help transferring assigned
       trustvalues from PGP to GnuPG.
 
     * New commands --lsign-key and made --sign-key a shortcut for --edit
       and sign.
 
     * New options (#122--126 ;-) --[no-]default-recipient[-self],
       --disable-{cipher,pubkey}-algo. See the man page.
 
     * Enhanced info output in case of multiple recipients and fixed exit code.
 
     * New option --allow-non-selfsigned-uid to work around a problem with
       the German IN way of separating signing and encryption keys.
 
     See-also: gnupg-announce/1999q3/000028.html
 
 
 Noteworthy changes in version 0.9.8 (1999-06-26)
 -----------------------------------
 
     * New subcommand "delsig" in the edit menu.
 
     * The name of the output file is not anymore the one which is
       embedded in the processed message, but the used filename with
       the extension stripped.  To revert to the old behaviour you can
       use the option --use-embedded-filename.
 
     * Another hack to cope with pgp2 generated detached signatures.
 
     * latin-2 character set works (--charset=iso-8859-2).
 
     * New option --with-key-data to list the public key parameters.
       New option -N to insert notations and a --set-policy-url.
       A couple of other options to allow reseting of options.
 
     * Better support for HPUX.
 
     See-also: gnupg-announce/1999q2/000016.html
 
 
 Noteworthy changes in version 0.9.7 (1999-05-23)
 -----------------------------------
 
     * Add some work arounds for a bugs in pgp 2 which led to bad signatures
       when used with canonical texts in some cases.
 
     * Enhanced some status outputs.
 
     See-also: gnupg-announce/1999q2/000000.html
 
 
 Noteworthy changes in version 0.9.6 (1999-05-06)
 -----------------------------------
 
     * Twofish is now statically linked by default. The experimental 128 bit
       version is now disabled.	Full support will be available as soon as
       the OpenPGP WG has decided on an interpretation of rfc2440.
 
     * Dropped support for the ancient Blowfish160 which is not OpenPGP.
 
     * Merged gpgm and gpg into one binary.
 
     * Add "revsig" and "revkey" commands to the edit menu.  It is now
       possible to revoke signature and subkeys.
 
 
 Noteworthy changes in version 0.9.5 (1999-03-20)
 -----------------------------------
 
     * New command "lsign" in the keyedit menu to create non-exportable
       signatures.  Removed --trusted-keys option.
 
     * A bunch of changes to the key validation code.
 
     * --list-trust-path now has an optional --with-colons format.
 
     * New command --recv-keys to import keys from an keyserver.
 
 
 Noteworthy changes in version 0.9.4 (1999-03-08)
 -----------------------------------
 
     * New configure option --enable-static-rnd=[egd|linux|unix|none]
       to select a random gathering module for static linking.
 
     * The original text is now verbatim copied to a cleartext signed message.
 
     * Bugfixes but there are still a couple of bugs.
 
 
 Noteworthy changes in version 0.9.3 (1999-02-19)
 -----------------------------------
 
     * Changed the internal design of getkey which now allows a
       efficient lookup of multiple keys and add a word match mode.
 
     * New options --[no-]encrypt-to.
 
     * Some changes to the configure stuff.  Switched to automake 1.4.
       Removed intl/ from CVS, autogen.sh now uses gettextize.
 
     * Preferences now include Twofish. Removed preference to Blowfish with
       a special hack to suppress the "not listed in preferences" warning;
       this is to allow us to switch completely to Twofish in the near future.
 
     * Changed the locking stuff.
 
     * Print all user ids of a good signature.
 
 
 Noteworthy changes in version 0.9.2 (1999-01-01)
 -----------------------------------
 
     * add some additional time warp checks.
 
     * Option --keyserver and command --send-keys to utilize HKP servers.
 
     * Upgraded to zlib 1.1.3 and fixed an inflate bug
 
     * More cleanup on the cleartext signatures.
 
 
 Noteworthy changes in version 0.9.1 (1999-01-01)
 -----------------------------------
 
     * Polish language support.
 
     * When querying the passphrase, the key ID of the primary key is
       displayed along with the one of the used secondary key.
 
     * Fixed a bug occurring when decrypting pgp 5 encrypted messages,
       fixed an infinite loop bug in the 3DES code and in the code
       which looks for trusted signatures.
 
     * Fixed a bug in the mpi library which caused signatures not to
       compare okay.
 
     * Rewrote the handling of cleartext signatures; the code is now
       better maintainable (I hope so).
 
     * New status output VALIDSIG only for valid signatures together
       with the fingerprint of the signer's key.
 
 
 Noteworthy changes in version 0.9.0 (1998-12-23)
 -----------------------------------
 
     * --export does now only exports rfc2440 compatible keys; the
       old behaviour is available with --export-all.
       Generation of v3 ElGamal (sign and encrypt) keys is not longer
       supported.
 
     * Fixed the uncompress bug.
 
     * Rewrote the rndunix module. There are two environment variables
       used for debugging now: GNUPG_RNDUNIX_DBG give the file to write
       debugging information (use "-" for stdout) and if GNUPG_RNDUNIX_DBGALL
       is set, all programs which are only tried are also printed.
 
     * New option --escape-from-lines to "dash-escape" "From " lines to
       prevent mailers to change them to ">From ".  This is not enabled by
       default because it is not in compliance with rfc2440 - however, you
       should turn it on.
 
 
 Noteworthy changes in version 0.4.5 (1998-12-08)
 -----------------------------------
 
     * The keyrings and the trustdb is now locked, so that
       other GnuPG processes won't damage these files.  You
       may want to put the option --lock-once into your options file.
 
     * The latest self-signatures are now used; this enables --import
       to see updated preferences etc.
 
     * Import of subkeys should now work.
 
     * Random gathering modules may now be loaded as extensions. Add
       such a module for most Unices but it is very experimental!
 
     * Brazilian language support.
 
 
 Noteworthy changes in version 0.4.4 (1998-11-20)
 -----------------------------------
 
     * Fixed the way the key expiration time is stored. If you have
       an expiration time on your key you should fix it with --edit-key
       and the command "expire".  I apologize for this inconvenience.
 
     * Add option --charset to support "koi8-r" encoding of user ids.
       (Not yet tested).
 
     * Preferences should now work again. You should run
       "gpgm --check-trustdb \*" to rebuild all preferences.
 
     * Checking of certificates should now work but this needs a lot
       of testing.  Key validation values are now cached in the
       trustdb; they should be recalculated as needed, but you may
       use --check-trustdb or --update-trustdb to do this.
 
     * Spanish translation by Urko Lusa.
 
     * Patch files are from now on signed.  See the man page
       for the new option --not-dash-escaped.
 
     * New syntax: --edit-key <userID> [<commands>]
       If you run it without --batch the commands are executed and then
       you are put into normal mode unless you use "quit" or "save" as
       one of the commands.  When in batch mode, the program quits after
       the last command, so you have to use "save" if you did some changes.
       It does not yet work completely, but may be used to list so the
       keys etc.
 
 
 Noteworthy changes in version 0.4.3 (1998-11-08)
 -----------------------------------
 
     * Fixed the gettext configure bug.
 
     * Kludge for RSA keys: keyid and length of a RSA key are
       correctly reported, but you get an error if you try to use
       this key (If you do not have the non-US version).
 
     * Experimental support for keyrings stored in a GDBM database.
       This is *much* faster than a standard keyring.  You will notice
       that the import gets slower with time; the reason is that all
       new keys are used to verify signatures of previous inserted
       keys.  Use "--keyring gnupg-gdbm:<name-of-gdbm-file>".  This is
       not (yet) supported for secret keys.
 
     * A Russian language file in the distribution (alternatives are in
       the contrib directory of the FTP servers)
 
     * commandline option processing now works as expected for GNU programs
       with the exception that you can't mix options and normal arguments.
 
     * Now --list-key lists all matching keys.  This is needed in some
       other places too.
 
 
 Noteworthy changes in version 0.4.2 (1998-10-18)
 -----------------------------------
 
     * This is only a snapshot: There are still a few bugs.
 
     * Fixed this huge memory leak.
 
     * Redesigned the trust database:  You should run "gpgm --check-trustdb".
       New command --update-trustdb, which adds new key from the public
       keyring into your trustdb
 
     * Fixed a bug in the armor code, leading to invalid packet errors.
       (a workaround for this was to use --no-armor).  The shorten line
       length (64 instead of 72) fixes a problem with pgp5 and keyservers.
 
     * comment packets are not anymore generated. "--export" filters
       them out.  One Exception:  The comment packets in a secret keyring
       are still used because they carry the factorization of the public
       prime product.
 
     * --import now only looks for KEYBLOCK headers, so you can now simply
       remove the "- " in front of such a header if someone accidentally signed
       such a message or the keyblock is part of a cleartext signed message.
 
     * --with-colons now lists the key expiration time and not anymore
       the valid period.
 
     * Some keyblocks created with old releases have a wrong sequence
       of packets, so that the keyservers don't accept these keys.
       Simply using "--edit-key" fixes the problem.
 
     * New option --force-v3-sigs to generate signed messages which are
       compatible to PGP 5.
 
     * Add some code to support DLD (for non ELF systems) - but this is
       not tested because my BSD box is currently broken.
 
     * New command "expire" in the edit-key menu.
 
 
 
 Noteworthy changes in version 0.4.1 (1998-10-07)
 -----------------------------------
 
     * A secondary key is used when the primary key is specified but cannot
       be used for the operation (if it is a sign-only key).
 
     * GNUPG can now handle concatenated armored messages:  There is still a
       bug if different kinds of messages are mixed.
 
     * Iterated+Salted passphrases now work.  If want to be sure that PGP5
       is able to handle them you may want to use the options
 	"--s2k-mode 3 --s2k-cipher-algo cast5 --s2k-digest-algo sha1"
       when changing a passphrase.
 
     * doc/OpenPGP talks about OpenPGP compliance, doc/HACKING gives
       a few hints about the internal structure.
 
     * Checked gnupg against the August 1998 draft (07) and I believe
       it is in compliance with this document (except for one point).
 
     * Fixed some bugs in the import merging code and rewrote some
       code for the trustdb.
 
 
 Noteworthy changes in version 0.4.0 (1998-09-18)
 -----------------------------------
 
     * Triple DES is now supported.  Michael Roth did this piece of
       needed work.  We have now all the coded needed to be OpenPGP
       compliant.
 
     * Added a simple rpm spec file (see INSTALL).
 
     * detached and armored signatures are now using "PGP SIGNATURE",
       except when --rfc1991 is used.
 
     * All times which are not in the yyyy-mm-dd format are now printed
       in local time.
 
 
 Noteworthy changes in version 0.3.5 (1998-09-14)
 -----------------------------------
 
     * New option --throw-keyid to create anonymous enciphered messages.
       If gpg detects such a message it tires all available secret keys
       in turn so decode it.  This is a gnupg extension and not in OpenPGP
       but it has been discussed there and afaik some products use this
       scheme too (Suggested by Nimrod Zimmerman).
 
     * Fixed a bug with 5 byte length headers.
 
     * --delete-[secret-]key is now also available in gpgm.
 
     * cleartext signatures are not anymore converted to LF only.
 
     * Fixed a trustdb problem.	Run "gpgm --check-trustdb" to fix old
       trust dbs.
 
     * Building in another directory should now work.
 
     * Weak key detection mechanism (Niklas Hernaeus).
 
 
 Noteworthy changes in version 0.3.4 (1998-08-11)
 -----------------------------------
 
     * New options --comment and --set-filename; see g10/OPTIONS
 
     * yes/no, y/n localized.
 
     * Fixed some bugs.
 
 
 Noteworthy changes in version 0.3.3 (1998-08-08)
 -----------------------------------
 
     * IMPORTANT: I found yet another bug in the way the secret keys
       are encrypted - I did it the way pgp 2.x did it, but OpenPGP
       and pgp 5.x specify another (in some aspects simpler) method.
       To convert your secret keys you have to do this:
 	1. Build the new release but don't install it and keep
 	   a copy of the old program.
 	2. Disable the network, make sure that you are the only
 	   user, be sure that there are no Trojan horses etc ....
 	3. Use your old gpg (version 0.3.1 or 0.3.2) and set the
 	   passphrases of ALL your secret keys to empty!
 	   (gpg --change-passphrase your-user-id).
 	4. Save your ownertrusts (see the next point)
 	5. rm ~/.gnupg/trustdb.gpg
 	6. install the new version of gpg (0.3.3)
 	7. For every secret key call "gpg --edit-key your-user-id",
 	   enter "passwd" at the prompt, follow the instructions and
 	   change your password back, enter "save" to store it.
 	8. Restore the ownertrust (see next point).
 
     * The format of the trust database has changed; you must delete
       the old one, so gnupg can create a new one.
       IMPORTANT: Use version 0.3.1 or .2 to save your assigned ownertrusts
       ("gpgm --list-ownertrust >saved-trust"); then build this new version
       and restore the ownertrust with this new version
       ("gpgm --import-ownertrust saved-trust").  Please note that
       --list-ownertrust has been renamed to --export-ownertrust in this
       release and it does now only export defined ownertrusts.
 
     * The command --edit-key now provides a commandline driven menu
       which can be used for various tasks.  --sign-key is only an
       an alias to --edit-key and maybe removed in future: use the
       command "sign" of this new menu - you can select which user ids
       you want to sign.
 
     * Alternate user ids can now be created an signed.
 
     * Owner trust values can now be changed with --edit-key (trust)
 
     * GNUPG can now run as a coprocess; this enables sophisticated
       frontends.  tools/shmtest.c is a simple sample implementation.
       This needs some more work: all tty_xxx() are to be replaced
       by cpr_xxx() and some changes in the display logics is needed.
 
     * Removed options --gen-prime and --gen-random.
 
     * Removed option --add-key; use --edit-key instead.
 
     * Removed option --change-passphrase; use --edit-key instead.
 
     * Signatures are now checked even if the output file could not
       be created. Command "--verify" tries to find the detached data.
 
     * gpg now disables core dumps.
 
     * compress and symmetric cipher preferences are now used.
       Because there is no 3DES yet, this is replaced by Blowfish.
 
     * We have added the Twofish as an experimental cipher algorithm.
       Many thanks to Matthew Skala for doing this work.
       Twofish is the AES submission from Schneier et al.; see
       "www.counterpane.com/twofish.html" for more information.
 
     * Started with a help system: If you enter a question mark at some
       prompt; you should get a specific help for this prompt.
 
     * There is no more backup copy of the secret keyring.
 
     * A lot of new bugs. I think this release is not as stable as
       the previous one.
 
 
 Noteworthy changes in version 0.3.2 (1998-07-09)
 -----------------------------------
 
     * Fixed some bugs when using --textmode (-seat)
 
     * Now displays the trust status of a positive verified message.
 
     * Keyrings are now scanned in the sequence they are added with
       --[secret-]keyring.  Note that the default keyring is implicitly
       added as the very first one unless --no-default-keyring is used.
 
     * Fixed setuid and dlopen bug.
 
 
 Noteworthy changes in version 0.3.1 (1998-07-06)
 -----------------------------------
 
     * Partial headers are now written in the OpenPGP format if
       a key in a v4 packet is used.
 
     * Removed some unused options, removed the gnupg.sig stuff.
 
     * Key lookup by name now returns a key which can be used for
       the desired action.
 
     * New options --list-ownertrust (gpgm) to make a backup copy
       of the ownertrust values you assigned.
 
     * clear signature headers are now in compliance with OpenPGP.
 
 
 Noteworthy changes in version 0.3.0 (1998-06-25)
 -----------------------------------
 
     * New option --emulate-checksum-bug.  If your passphrase does not
       work anymore, use this option and --change-passphrase to rewrite
       your passphrase.
 
     * More complete v4 key support: Preferences and expiration time
       is set into the self signature.
 
     * Key generation defaults to DSA/ElGamal keys, so that new keys are
       interoperable with pgp5
 
     * DSA key generation is faster and key generation does not anymore
       remove entropy from the random generator (the primes are public
       parameters, so there is really no need for a cryptographic secure
       prime number generator which we had used).
 
     * A complete new structure for representing the key parameters.
 
     * Removed most public key knowledge into the cipher library.
 
     * Support for dynamic loading of new algorithms.
 
     * Moved tiger to an extension module.
 
 
 Noteworthy changes in version 0.2.19 (1998-05-29)
 ------------------------------------
 
     * Replaced /dev/urandom in checks with new tool mk-tdata.
 
     * Some assembler file cleanups; some more functions for the Alpha.
 
     * Tiger has now the OpenPGP assigned number 6.  Because the OID has
       changed, old signatures using this algorithm can't be verified.
 
     * gnupg now encrypts the compressed packed and not any longer in the
       reverse order; anyway it can decrypt both versions. Thanks to Tom
       for telling me this (not security related) bug.
 
     * --add-key works and you are now able to generate subkeys.
 
     * It is now possible to generate ElGamal keys in v4 packets to create
       valid OpenPGP keys.
 
     * Some new features for better integration into MUAs.
 
 
 Noteworthy changes in version 0.2.18 (1998-05-15)
 ------------------------------------
 
     * Splitted cipher/random.c, add new option "--disable-dev-random"
       to configure to support the development of a random source for
       other systems. Prepared sourcefiles rand-unix.c, rand-w32.c
       and rand-dummy.c (which is used to allow compilation on systems
       without a random source).
 
     * Fixed a small bug in the key generation (it was possible that 48 bits
       of a key were not taken from the random pool)
 
     * Add key generation for DSA and v4 signatures.
 
     * Add a function trap_unaligned(), so that a SIGBUS is issued on
       Alphas and not the slow emulation code is used. And success: rmd160
       raised a SIGBUS.
 
     * Enhanced the formatting facility of argparse and changed the use of
       \r,\v to @ because gettext does not like it.
 
     * New option "--compress-algo 1" to allow the creation of compressed
       messages which are readable by PGP and "--print-md" (gpgm) to make
       speed measurement easier.
 
 
 Noteworthy changes in version 0.2.17 (1998-05-04)
 ------------------------------------
 
     * Comment packets are now of private type 61.
 
     * Passphrase code still used a 160 bit blowfish key, added a
       silly workaround. Please change your passphrase again - sorry.
 
     * Conventional encryption now uses a type 3 packet to describe the
       used algorithms.
 
     * The new algorithm number for Blowfish is 20, 16 is still used for
       encryption only; for signing it is only used when it is in a v3 packet,
       so that GNUPG keys are still valid.
 
 
 Noteworthy changes in version 0.2.16 (1998-04-28)
 ------------------------------------
 
     * Add experimental support for the TIGER/192 message digest algorithm.
       (But there is only a dummy ASN OID).
 
     * Standard cipher is now Blowfish with 128 bit key in OpenPGP's CFB
       mode. I renamed the old cipher to Blowfish160. Because the OpenPGP
       group refused to assign me a number for Blowfish160, I have to
       drop support for this in the future. You should use
       "--change-passphrase" to recode your current passphrase with 128
       bit Blowfish.
 
 
 Noteworthy changes in version 0.2.15 (1998-04-09)
 ------------------------------------
 
     * Fixed a bug with the old checksum calculation for secret keys.
       If you run the program without --batch, a warning does inform
       you if your secret key needs to be converted; simply use
       --change-passphrase to recalculate the checksum. Please do this
       soon, as the compatible mode will be removed sometime in the future.
 
     * CAST5 works (using the PGP's special CFB mode).
 
     * Again somewhat more PGP 5 compatible.
 
     * Some new test cases
 
 Noteworthy changes in version 0.2.14 (1998-04-02)
 ------------------------------------
 
     * Changed the internal handling of keyrings.
 
     * Add support to list PGP 5 keyrings with subkeys
 
     * Timestamps of signatures are now verified.
 
     * A expiration time can now be specified during key generation.
 
     * Some speedups for Blowfish and SHA-1, rewrote SHA-1 transform.
       Reduced the amount of random bytes needed for key generation in
       some cases.
 
 
 Noteworthy changes in version 0.2.13 (1998-03-10)
 ------------------------------------
 
     * Verify of DSA signatures works.
 
     * Re-implemented the slower random number generator.
 
 
 Noteworthy changes in version 0.2.12 (1998-03-07)
 ------------------------------------
 
     * --delete-key checks that there is no secret key. The new
       option --delete-secret-key maybe used to delete a secret key.
 
     * "-kv" now works as expected. Options "--list-{keys,sigs]"
       and "--check-sigs" are now working.
 
     * New options "--verify" and "--decrypt" to better support integration
       into MUAs (partly done for Mutt).
 
     * New option "--with-colons" to make parsing of key lists easier.
 
 Noteworthy changes in version 0.2.11 (1998-03-02)
 ------------------------------------
 
     * GPG now asks for a recipient's name if option "-r" is not used.
 
     * If there is no good trust path, the program asks whether to use
       the public keys anyway.
 
     * "--delete-key" works for public keys. What semantics shall I use
       when there is a secret key too? Delete the secret key or leave him
       and auto-regenerate the public key, next time the secret key is used?
 
 Noteworthy changes in version 0.2.10 (1998-02-27)
 ------------------------------------
 
     * Code for the alpha is much faster (about 20 times); the data
       was misaligned and the kernel traps this, so nearly all time
       was used by system to trap the misalignments and to write
       syslog messages. Shame on me and thanks to Ralph for
       pointing me at this while drinking some beer yesterday.
 
     * Changed some configure options and add an option
       --disable-m-guard to remove the memory checking code
       and to compile everything with optimization on.
 
     * New environment variable GNUPGHOME, which can be used to set
       another homedir than ~/.gnupg.  Changed default homedir for
       Windoze version to c:/gnupg.
 
     * Fixed detached signatures; detached PGP signatures caused a SEGV.
 
     * The Windoze version works (as usual w/o a strong RNG).
 
 
 Noteworthy changes in version 0.2.9 (1998-02-26)
 -----------------------------------
 
     * Fixed FreeBSD bug.
 
     * Added a simple man page.
 
     * Switched to automake1.2f and a newer gettext.
 
 Noteworthy changes in version 0.2.8 (1998-02-24)
 -----------------------------------
 
     * Changed the name to GNUPG, the binaries are called gpg and gpgm.
       You must rename rename the directory "~/.g10" to ~/.gnupg/, rename
       {pub,sec}ring.g10 to {pub,sec}ring.gpg, trustdb.g10 to trustdb.gpg
       and g10.sig to gnupg.sig.
 
     * New or changed passphrases are now salted.
 
 
 Noteworthy changes in version 0.2.7 (1998-02-18)
 -----------------------------------
 
     * New command "gen-revoke" to create a key revocation certificate.
 
     * New option "homedir" to set the homedir (which defaults to "~/.g10").
       This directory is created if it does not exists (only the last
       part of the name and not the complete hierarchy)
 
     * Command "import" works. (Try: "finger gcrypt@ftp.guug.de|g10 --import")
 
     * New commands "dearmor/enarmor" for g10maint.  These are mainly
       used for internal test purposes.
 
     * Option --version now conforming to the GNU standards and lists
       the available ciphers, message digests and public key algorithms.
 
     * Assembler code for m68k (not tested).
 
     * "make check" works.
 
 Noteworthy changes in version 0.2.6 (1998-02-13)
 -----------------------------------
 
     * Option "--export" works.
 
 
 Noteworthy changes in version 0.2.5 (1998-02-12)
 -----------------------------------
 
     * Added zlib for systems which don't have it.
       Use "./configure --with-zlib" to link with the static version.
 
     * Generalized some more functions and rewrote the encoding of
       message digests into MPIs.
 
     * Enhanced the checkit script
 
 
 Noteworthy changes in version 0.2.4 (1998-02-11)
 -----------------------------------
 
     * nearly doubled the speed of the ElGamal signature verification.
 
     * backup copies of keyrings are created.
 
     * assembler stuff for Pentium; gives about 15% better performance.
 
     * fixed a lot of bugs.
 
 
 Noteworthy changes in version 0.2.3 (1998-02-09)
 -----------------------------------
 
     * Found a bug in the calculation of ELG fingerprints. This is now
       fixed, but all existing fingerprints and keyids for ELG keys
       are not any more valid.
 
     * armor should now work; including clear signed text.
 
     * moved some options to the new program g10maint
 
     * It's now 64 bit clean and runs fine on an alpha--linux.
 
     * Key generation is much faster now.  I fixed this by using not
       so strong random number for the primes (this was a bug because the
       ElGamal primes are public parameters and it does not make sense
       to generate them from strong random).  The real secret is the x value
       which is still generated from strong (okay: /dev/random) random bits.
 
     * added option "--status-fd": see g10/OPTIONS
 
     * We have secure memory on systems which support mlock().
       It is not complete yet, because we do not have signal handler
       which does a cleanup in very case.
       We should also check the ulimit for the user in the case
       that the admin does not have set a limit on locked pages.
 
     * started with internationalization support.
 
     * The logic to handle the web of trust is now implemented. It is
       has some bugs; but I'm going to change the algorithm anyway.
       It works by calculating the trustlevel on the fly.  It may ask
       you to provide trust parameters if the calculated trust probability
       is too low.  I will write a paper which discusses this new approach.
 
     * a couple of changes to the configure script.
 
     * New option "--quick-random" which uses a much quicker random
       number generator.  Keys generated while this option is in effect
       are flags with "INSECURE!" in the user-id.  This is a development
       only option.
 
     * Read support for new version packets (OpenPGP).
 
     * Comment packets are now of correct OpenPGP type 16. Old comment
       packets written by G10 are detected because they always start with
       a hash which is an invalid version byte.
 
     * The string "(INSECURE!)" is appended to a new user-id if this
       is generated on a system without a good random number generator.
