 Noteworthy changes in version 1.11.0 (2018-04-18)
 -------------------------------------------------
 
  * New encryption API to support direct key specification including
    hidden recipients option and taking keys from a file.  This also
    allows to enforce the use of a subkey.
 
  * New encryption flag for the new API to enforce the use of plain
    mail addresses (addr-spec).
 
  * The import API can now tell whether v3 keys are skipped.  These old
    and basically broken keys are not anymore supported by GnuPG 2.1.
 
  * The decrypt and verify API will now return the MIME flag as
    specified by RFC-4880bis.
 
  * The offline mode now has an effect on gpg by disabling all network
    access.  [#3831]
 
  * A failed OpenPGP verification how returns the fingerprint of the
    intended key if a recent gpg version was used for signature
    creation.
 
  * New tool gpgme-json as native messaging server for web browsers.
    As of now public key encryption and decryption is supported.
    Requires Libgpg-error 1.29.
 
  * New context flag "request-origin" which has an effect when used
    with GnuPG 2.2.6 or later.
 
  * New context flag "no-symkey-cache" which has an effect when used
    with GnuPG 2.2.7 or later.
 
  * New convenience constant GPGME_KEYLIST_MODE_LOCATE.
 
  * Improved the Python documentation.
 
  * Fixed a potential regression with GnuPG 2.2.6 or later.
 
  * Fixed a crash in the Python bindings on 32 bit platforms.  [#3892]
 
  * Various minor fixes.

 -------------------------------------------------
 
  * Now returns more specific error codes for decryption to distinguish
    between bad passphrase, user canceled, and no secret key.
 
  * Now returns key origin information if available.
 
  * Added context flag "auto-key-retrieve" to selectively enable the
    corresponding gpg option.
 
  * Added flag is_de_vs to decryption and verify results.
 
  * py: Use SEEK_SET as default for data.seek.
 
  * cpp: Various new APIs.
 
  * Reduced spawn overhead on Linux again.  Added new configure option
    --disable-linux-getdents to disable this feature for very old
    Linux versions.

  * GPGME does not come with an internal libassuan version anymore.
    The external libassuan 1.1.0 release or later is required.  For
    application programmers on systems that can resolve inter-library
    dependencies at runtime, this is a transparent change.

    result structures from a context.
 
  * New functions gpgme_op_export_keys_start and gpgme_op_export_keys
    that allow to specify exported keys through gpgme_key_t objects
    instead of patterns.

 Noteworthy changes in version 1.1.8 (2008-12-08)
 ------------------------------------------------
 
  * SIGPIPE is now again ignored as described in the manual.  Fixes
    regression introduced with 1.1.6.
 
 
 Noteworthy changes in version 1.1.7 (2008-10-17)
 ------------------------------------------------
 
  * Using GPGME_KEYLIST_MODE_LOCAL combined with
    GPGME_KEYLIST_MODE_EXTERN is now supported; it uses the
    --locate-keys feature of gpg (>= 2.0.10).
 
  * The encoding of gpgme_data_t objects can affect the output encoding
    of export, sign and encrypt operations now (the same operations
    that are also affected by the ASCII mode switch).  We believe this
    change in the ABI is innocent enough not to break existing
    applications (it only affects the S/MIME backend on certain
    operations).
 
  * The reference manual now includes the specification of "The GnuPG
    UI Server protocol".
 
  * A new function gpgme_cancel_async can be used to asynchronously
    cancel any pending operation at any time, from any thread.
 
  * Interface changes relative to the 1.1.6 release:

  * Bug fixes for for W32.
 
  * A new, experimental (and thus undocumented and potentially
    unstable) interface for accessing gpg-conf through GPGME has been
    added.
 
  * Interface changes relative to the 1.1.1 release:

 Noteworthy changes in version 1.1.5 (2007-07-09)
 ------------------------------------------------
 
  * Bug and portability fixes (mainly for W32).
 
 
 Noteworthy changes in version 1.1.4 (2007-03-05)
 ------------------------------------------------
 
  * Detect and bail out on double plaintext messages.  This is required
    so that applications can properly detect the signed parts of a
    message.  Actual there is now a double protection as GnuPG 1.4.7
    will detect this case too.
 
 
 Noteworthy changes in version 1.1.3 (2007-01-29)
 ------------------------------------------------
 
  * Fixed a memory leak in gpgme_data_release_and_get_mem.
 
  * Fixed a bug in Windows command line quoting.
 
 
 Noteworthy changes in version 1.1.2 (2006-03-02)
 ------------------------------------------------
 
  * Fixed a bug in the W32 glib backend.
 
 
 Noteworthy changes in version 1.1.1 (2006-02-23)
 ------------------------------------------------
 
  * Fixed a bug in that the fingerprints of subkeys are not available.
 
  * Clarified usage of the SECRET flag in key listings.  It is now
    reset for stub keys.
 
  * Reading signature notations and policy URLs on key signatures is
    supported.  They can be found in the new field notations of the
    gpgme_key_sig_t structure.  This has to be enabled with the keylist
    mode flag GPGME_KEYLIST_MODE_SIG_NOTATIONS.
 
  * A new gpgme_free() function solves the problem of using different
    allocators in a single program.  This function should now be used
    instead calling free() to release the buffer returned by
    gpgme_data_release_and_get_mem.  It is recommended that you always
    do this, but it is only necessary on certain platforms, so backwards
    compatibility is provided.  In other words: If free() worked for
    you before, it will keep working.
 
  * New status codes GPGME_PKA_TRUST_GOOD and GPGME_PKA_TRUST_BAD.
    They are analyzed by the verify handlers and made available in the
    new PKA_TRUST and PKA_ADDRESS fields of the signature result structure.
 
  * Interface changes relative to the 1.1.0 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_key_sig_t			EXTENDED: New field notations.

 Noteworthy changes in version 1.1.0 (2005-10-01)
 ------------------------------------------------
 
  * You can now configure the backend engine file name and home
    directory to be used, as default and per context.
 
  * Information about the recipients of an encrypted text is now
    available at decryption time.
 
  * New status GPGME_STATUS_PLAINTEXT.  This is analyzed by the decrypt
    and verify handlers, the information about the plaintext filename,
    if available is made available in the new field file_name of the
    respective result structure.
 
  * The code for "automagically detecting the thread library" has been
    removed from libgpgme.  It is deprecated since version 0.4.3.
    Since then, you had to link against libgpgme-pthread for
    applications using pthread and libgpgme-pth for applications using
    GNU Pth.
 
    The code was removed because it caused compilation problems on
    systems where the pthread.h header from GNU Pth is available in
    addition to the system header (FreeBSD 6 and later for example).
 
  * "./autogen.sh --build-w32" does now build gpgme.dll.
 
  * [W32] The environment variable GPGME_DEBUG now uses a semicolon as
    delimiter.  The standard install directory is used when locating
    gpg or gpgsm before finally falling back to the hardwired name.
 
  * There is a new flag for keys and subkeys, is_qualified, which
    indicates if a key can be used for qualified signatures according
    to local government regulations.
 
  * You can associate a filename with a data object using the new
    function gpgme_data_set_file_name().  This filename will be stored
    in the output when encrypting or signing the data and will be
    returned when decrypting or verifying the output data.
 
  * You can now set notation data at signature creation with the new
    function gpgme_sig_notation_add().

 Noteworthy changes in version 1.0.3 (2005-06-20)
 ------------------------------------------------
 
  * Previousy, GPGME would use a default "include certs" of 1.  This
    has been changed.  Now GPGME will use the crypto backend engines
    default unless you set the value with gpgme_set_include_certs()
    explicitly.  A new macro GPGME_INCLUDE_CERTS_DEFAULT can be used
    as a value to explicitly request the new default behaviour.
 
    Because the default changes, this is a slight change of the API
    semantics.  We consider it to be a bug fix.
 
  * A bug which made GPGME hang has been fixed.  If you have
    experienced hanging before, please try out this version and let me
    know if you still experience hanging problems.
 
  * Interface changes relative to the 0.9.0 release:

 Noteworthy changes in version 1.0.0 (2004-09-30)
 ------------------------------------------------
 
  * Version 1.0.0!  We are proud to present you with a thoroughly
    tested and stable version of the GPGME library.  A big Thank You!
    to all the people who made this possible.
 
    The development will be branched into a stable 1.x.y series and the
    head.
 
  * The gpgme.m4 macro supports checking the API version.  Just prepend
    it to the required version string, separated by a colon.  For
    example, this release has the version "1:1.0.0".  The last release
    to which this version is (mostly) ABI compatible is "1:0.4.2",
    which is the default required version.
 
 
 Noteworthy changes in version 0.9.0 (2004-06-08)
 ------------------------------------------------
 
  * The type gpgme_key_t has now a new field keylist_mode that contains
    the keylist mode that was active at the time the key was retrieved.
 
  * The type gpgme_decrypt_result_t has a new field "wrong_key_usage"
    that contains a flag indicating that the key should not have been
    used for encryption.
 
  * Verifying a signature of a revoked key gives the correct result now
    (GPG_ERR_CERT_REVOKED error code).
 
  * Clarified that the error code GPG_ERR_NO_DATA from the decrypt &
    verify operations still allows you to look at the signature
    verification result.
 
  * Clarified that patterns in keylisting operations have an upper
    limit, and thus are not suited to list many keys at once by their
    fingerprint.  Also improve the error message if the pattern is too
    long for the CMS protocol to handle.

  * Correctly initialize the fields expired, revoked, invalid, and
    disabled in the gpgme_key_t structures.
 
  * A bug fix: The flag wrong_key_usage of gpgme_signature_t was
    accidentally of type int instead unsigned int.
 
  * Interface changes relative to the 0.4.5 release:

 ------------------------------------------------
 
  * Bug fixes
 
 
 Noteworthy changes in version 0.4.5 (2004-03-07)
 ------------------------------------------------
 
  * GPGME is now compiled with LFS (large file support) by default.
    This means that _all_ programs using GPGME must be compiled with
    LFS support enabled by default.  You can do this easily with
    autoconf, by using the AC_SYS_LARGEFILE macro.  Or you can do this
    without autoconf by defining the preprocessor symbol
    _FILE_OFFSET_BITS to 64 (by passing the -D_FILE_OFFSET_BITS=64 to
    the C compiler command line, or by defining this preprocessor
    symbol before including any system header files).  For more
    details, read the section on LFS in the manual.
 
    Up to now, it was undocumented that GPGME was not using LFS.
    But the public interfaces use off_t, and file descriptors are
    exchanged between the application and GPGME.  This was an oversight,
    and bound to cause troubles in the future.
 
    Writing GPGME as a dual mode library that seamlessly supports LFS
    while keeping backwards compatibility is possible, but does not
    solve the problem: Many applications already expect GPGME to have
    LFS (they are compiled with off_t being a 64bit value).  This is true
    in particular for the popular Gtk+ and Qt programs.
 
    So, although this is an ABI (but not an API) break, we will not
    change the library version to reflect that.  Because the interfaces
    affected are probably not used yet in any GPGME 0.4 based
    application, we don't expect any real failures from this change.
    In fact, applications already using LFS will have some subtle bugs
    fixed.
 
    However, if you encounter an application using GPGME 0.4.x that
    does _not_ use LFS by default (off_t is a 32bit value), _and_
    uses at least one of the functions gpgme_data_seek,
    gpgme_data_new_from_filepart, or a gpgme_data_seek_cb_t with
    gpgme_data_new_from_cbs, then indeed this library will be ABI
    incompatible with the program.  As said above, we don't believe
    such a program exists.  If we are in error, then you have two
    options: As a quick hack, you can configure GPGME with the
    --disable-largefile option.  This will revert the change, and GPGME
    will not use LFS.  However, GPGME will be incompatible with
    programs that expect GPGME to use LFS.  All applications are
    required to use LFS when using GPGME, so this is only good as a
    temporary local work-around.
 
    The other option is to change the versioning of the library and
    recompile all applications.  We have reserved a special version of
    the library for that, so you can do that without expecting a
    version clash in the future.  Furthermore, everyone who does this
    will agree on the version to use (this is important for
    distribution makers).  Read the comment in configure.ac (before
    LIBGPGME_LT_AGE) if you want to do this.  Please don't do this
    blindly: As stated above, we think it is unlikely this measure is
    needed.  Still, it is there if necessary.  If in doubt, contact us
    and we will give our advise for your specific situation.
 
  * New key listing mode GPGME_KEYLIST_MODE_VALIDATE for validation of
    the listed keys.
 
  * New interface gpgme_cancel() that can be used to cancel
    asynchronous operations.

 Noteworthy changes in version 0.4.4 (2004-01-12)
 ------------------------------------------------
 
  * The member "class" in gpgme_key_sig_t and gpgme_new_signature_t has
    been renamed to "sig_class", to avoid clash with C++ compilers.  In
    the C API, the old name "class" has been preserved for backwards
    compatibility, but is deprecated.

 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_key_sig_t			CHANGED: class deprecated, use new sig_class.

 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Noteworthy changes in version 0.4.3 (2003-10-06)
 ------------------------------------------------
 
  * libgpgme should not be used for threaded programs anymore.  This
    never worked reliably in all cases, because you had to
    be careful about the linking order and libtool wouldn't do that for
    you automatically.  Instead, now you have to link against
    libgpgme-pthread for applications using pthread and libgpgme-pth for
    applications using GNU Pth.
 
    The old code for automagically detecting the thread library is
    still part of libgpgme, but it is DEPRECATED.
 
  * There are new automake macros AM_PATH_GPGME_PTH and
    AM_PATH_GPGME_PTHREAD, which support checking for thread-enabled
    versions of GPGME.  They define GPGME_PTH_CFLAGS, GPGME_PTH_LIBS,
    GPGME_PTHREAD_CFLAGS and GPGME_PTHREAD_LIBS respectively.  These
    variables of course also include the configuration for the thread
    package itself.  Alternatively, use libtool.
 
  * gpgme_strerror_r as a thread safe variant of gpgme_strerror was
    added.
 
  * gpgme-config doesn't support setting the prefix or exec prefix
    anymore.  I don't think it ever worked correctly, and it seems to
    be pointless.
 
  * gpgme_get_key fails with GPG_ERR_AMBIGUOUS_NAME if the key ID
    provided was not unique, instead returning the first matching key.
 
  * gpgme_key_t and gpgme_subkey_t have a new field, can_authenticate,
    that indicates if the key can be used for authentication.
 
  * gpgme_signature_t's status field is now correctly set to an error
    with error code GPG_ERR_NO_PUBKEY if public key is not found.
 
  * gpgme_new_signature_t's class field is now an unsigned int, rather
    than an unsigned long (the old class field is preserved for
    backwards compatibility).
 
  * A new function gpgme_set_locale() is provided to allow configuring
    the locale for the crypto backend.  This is necessary for text
    terminals so that programs like the pinentry can be started with
    the right locale settings for the terminal the application is running
    on, in case the terminal has different settings than the system
    default (for example, if it is a remote terminal).  You are highly
    recommended to call the following functions directly after
    gpgme_check_version:
 
    #include <locale.h>
 
    setlocale (LC_ALL, "");
    gpgme_set_locale (NULL, LC_CTYPE, setlocale (LC_CTYPE, NULL));
    gpgme_set_locale (NULL, LC_MESSAGES, setlocale (LC_MESSAGES, NULL));
 
    GPGME can not do this for you, as setlocale is not thread safe, and
    there is no alternative.
 
  * The signal action for SIGPIPE is now set to SIG_IGN by
    gpgme_check_version, instead the first time a crypto engine is
    started (which is not well defined).
 
  * In the output of gpgme_hash_algo_name, change RMD160 to RIPEMD160,
    TIGER to TIGER192, CRC32-RFC1510 to CRC32RFC1510, and CRC24-RFC2440
    to CRC24RFC2440.  For now, these strings can be used as the MIC
    parameter for PGP/MIME (if appropriately modified).
 
  * Interface changes relative to the 0.4.2 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_strerror_t		NEW
 gpgme_get_key			CHANGED: Fails correctly if key ID not unique.
 gpgme_key_t			EXTENDED: New field can_authenticate.
 gpgme_subkey_t			EXTENDED: New field can_authenticate.

 Noteworthy changes in version 0.4.2 (2003-07-30)
 ------------------------------------------------
 
  * Allow gpg-error to be in non-standard place when linking the test suite.
 
  * Configure will fail now if gpg-error can not be found.
 
  * Fixed initialized memory backed data objects for writing, which
    caused the test program to crash (but only on Mac OS, surprisingly).
 
  * Eliminate use of C99 constructs.
 
  * Small improvements to the manual.
 
 
 Noteworthy changes in version 0.4.1 (2003-06-06)
 ------------------------------------------------
 
  This is the release that 0.4.0 should have been.  There are many
  interface changes, please see below for the details.  The changes are
  sometimes the result of new functionality, but more often express a
  paradigm shift.  Others are an overdue cleanup to get GPGME in line
  with the GNU coding standards and to make the interface more
  self-consistent.  Here is an overview on the changes:
 
  All types have been renamed to conform to the GNU coding standards,
  most of the time by keeping the whole name in lowercase and inserting
  underscores between words.
 
  All operations consistently only accept input parameters in their
  invocation function, and return only an error code directly.  Further
  information about the result of the operation has to be retrieved
  afterwards by calling one of the result functions.  This unifies the
  synchronous and the asynchronous interface.
 
  The error values have been completely replaced by a more
  sophisticated model that allows GPGME to transparently and accurately
  report all errors from the other GnuPG components, regardless of
  process boundaries.  This is achieved by using the library
  libgpg-errors, which is shared by all GnuPG components.  This library
  is now required for GPGME.
 
  The results of all operations are now provided by pointers to C
  structs rather than by XML structs or in other ways.
 
  Objects which used to be opaque (for example a key) are now pointers
  to accessible structs, so no accessor functions are necessary.
 
  Backward compatibility is provided where it was possible without too
  much effort and did not collide with the overall sanitization effort.
  However, this is only for ease of transition.  NO DEPRECATED FUNCTION
  OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND WILL BE
  DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE LIBRARY.
  Recommendations how to replace deprecated or removed functionality
  can be found within the description of each change.
 
  What follows are all changes to the interface and behaviour of GPGME
  in detail.
 
  * If gpgme.h is included in sources compiled by GCC 3.1 or later,
    deprecated attributes will warn about use of obsolete functions and
    type definitions.  You can suppress these warnings by passing
    -Wno-deprecated-declarations to the gcc command.
 
  * The following types have been renamed.  The old types are still
    available as aliases, but they are deprecated now:
    Old name:		New name:
    GpgmeCtx		gpgme_ctx_t
    GpgmeData		gpgme_data_t
    GpgmeError		gpgme_error_t
    GpgmeDataEncoding	gpgme_data_encoding_t
    GpgmeSigStat		gpgme_sig_stat_t
    GpgmeSigMode		gpgme_sig_mode_t
    GpgmeAttr		gpgme_attr_t
    GpgmeValidity	gpgme_validity_t
    GpgmeProtocol	gpgme_protocol_t
    GpgmeKey		gpgme_key_t
    GpgmePassphraseCb	gpgme_passphrase_cb_t
    GpgmeProgressCb	gpgme_progress_cb_t
    GpgmeIOCb		gpgme_io_cb_t
    GpgmeRegisterIOCb	gpgme_register_io_cb_t
    GpgmeRemoveIOCb	gpgme_remove_io_cb_t
    GpgmeEventIO		gpgme_event_io_t
    GpgmeEventIOCb	gpgme_event_io_cb_t
    GpgmeIOCbs		gpgme_io_cbs
    GpgmeDataReadCb	gpgme_data_read_cb_t
    GpgmeDataWriteCb	gpgme_data_write_cb_t
    GpgmeDataSeekCb	gpgme_data_seek_cb_t
    GpgmeDataReleaseCb	gpgme_data_release_cb_t
    GpgmeDataCbs		gpgme_data_cbs_t
    GpgmeTrustItem	gpgme_trust_item_t
    GpgmeStatusCode	gpgme_status_code_t
 
  * gpgme_error_t is now identical to gpg_error_t, the error type
    provided by libgpg-error.  More about using libgpg-error with GPGME
    can be found in the manual.  All error symbols have been removed!
 
  * All functions and types in libgpg-error have been wrapped in GPGME.
    The new types are gpgme_err_code_t and gpgme_err_source_t.  The new
    functions are gpgme_err_code, gpgme_err_source, gpgme_error,
    gpgme_err_make, gpgme_error_from_errno, gpgme_err_make_from_errno,
    gpgme_err_code_from_errno, gpgme_err_code_to_errno,
    gpgme_strsource.
 
  * GPGME_ATTR_IS_SECRET is not anymore representable as a string.
 
  * GnuPG 1.2.2 is required.  The progress callback is now also invoked
    for encrypt, sign, encrypt-sign, decrypt, verify, and
    decrypt-verify operations.  For verify operations on detached
    signatures, the progress callback is invoked for both the detached
    signature and the plaintext message, though.
 
  * gpgme_passphrase_cb_t has been changed to not provide a complete
    description, but the UID hint, passphrase info and a flag
    indicating if this is a repeated attempt individually, so the user
    can compose his own description from this information.
 
    The passphrase is not returned as a C string, but must be written
    to a file descriptor directly.  This allows for secure passphrase
    entries.
 
    The return type has been changed to gpgme_error_t value.  This
    allowed to remove the gpgme_cancel function; just return
    the error code GPG_ERR_CANCELED in the passphrase callback directly.
 
  * gpgme_edit_cb_t has been changed to take a file descriptor argument.
    The user is expected to write the response to the file descriptor,
    followed by a newline.
 
  * The recipients interface has been removed.  Instead, you use
    NULL-terminated lists of keys for specifying the recipients of an
    encryption operation.  Use the new encryption flag
    GPGME_ENCRYPT_ALWAYS_TRUST if you want to override the validity of
    the keys (but note that in general this is not a good idea).
 
    This change has been made to the prototypes of gpgme_op_encrypt,
    gpgme_op_encrypt_start, gpgme_op_encrypt_sign and
    gpgme_op_encrypt_sign_start.
 
    The export interface has been changed to use pattern strings like
    the keylist interface.  Thus, new functions gpgme_op_export_ext and
    gpgme_op_export_ext_start have been added as well.  Now the
    prototypes of gpgme_op_export_start and gpgme_op_export finally
    make sense.
 
  * gpgme_op_verify and gpgme_op_decrypt_verify don't return a status
    summary anymore.  Use gpgme_get_sig_status to retrieve the individual
    stati.
 
  * gpgme_io_cb_t changed from a void function to a function returning
    a gpgme_error_t value.  However, it will always return 0, so you
    can safely ignore the return value.
 
  * A new I/O callback event GPGME_EVENT_START has been added.  The new
    requirement is that you must wait until this event until you are
    allowed to call the I/O callback handlers previously registered for
    this context operation.  Calling I/O callback functions for this
    context operation before the start event happened is unsafe because
    it can lead to race conditions in a multi-threaded environment.
 
  * The idle function feature has been removed.  It was not precisely
    defined in a multi-threaded environment and is obsoleted by the
    user I/O callback functions.  If you still need a simple way to
    call something while waiting on one or multiple asynchronous
    operations to complete, don't set the HANG flag in gpgme_wait (note
    that this will return to your program more often than the idle
    function did).
 
  * gpgme_wait can return NULL even if hang is true, if an error
    occurs.  In that case *status contains the error code.
 
  * gpgme_get_engine_info was radically changed.  Instead an XML
    string, an info structure of the new type gpgme_engine_info_t is
    returned.  This makes it easier and more robust to evaluate the
    information in an application.
 
  * The new function gpgme_get_protocol_name can be used to convert a
    gpgme_protocol_t value into a string.
 
  * The status of a context operation is not checked anymore.  Starting
    a new operation will silently cancel the previous one.  Calling a
    function that requires you to have started an operation before without
    doing so is undefined.
 
  * The FPR argument to gpgme_op_genkey was removed.  Instead, use the
    gpgme_op_genkey_result function to retrieve a gpgme_genkey_result_t
    pointer to a structure which contains the fingerprint.  This also
    works with gpgme_op_genkey_start.  The structure also provides
    other information about the generated keys.
 
    So, instead:
 
    char *fpr;
    err = gpgme_op_genkey (ctx, NULL, NULL, &fpr);
    if (!err && fpr)
      printf ("%s\n", fpr);
 
    you should now do:
 
    gpgme_genkey_result_t result;
    err = gpgme_op_genkey (ctx, NULL, NULL);
    if (!err)
      {
        result = gpgme_op_genkey_result (ctx);
        if (result->fpr)
          printf ("%s\n", result->fpr);
      }
 
  * The new gpgme_op_import_result function provides detailed
    information about the result of an import operation in
    gpgme_import_result_t and gpgme_import_status_t objects.
    Thus, the gpgme_op_import_ext variant is deprecated.
 
  * The new gpgme_op_sign_result function provides detailed information
    about the result of a signing operation in gpgme_sign_result_t,
    gpgme_invalid_key_t and gpgme_new_signature_t objects.
 
  * The new gpgme_op_encrypt_result function provides detailed
    information about the result of an encryption operation in
    a GpgmeEncryptResult object.
 
  * The new gpgme_op_decrypt_result function provides detailed
    information about the result of a decryption operation in
    a GpgmeDecryptResult object.
 
  * The new gpgme_op_verify_result function provides detailed
    information about the result of an verify operation in
    a GpgmeVerifyResult object.  Because of this, the GPGME_SIG_STAT_*
    values, gpgme_get_sig_status, gpgme_get_sig_ulong_attr,
    gpgme_get_sig_string_attr and gpgme_get_sig_key are now deprecated,
    and gpgme_get_notation is removed.
 
  * GpgmeTrustItem objects have now directly accessible data, so the
    gpgme_trust_item_get_string_attr and gpgme_trust_item_get_ulong_attr
    accessor functions are deprecated.  Also, reference counting is
    available through gpgme_trust_item_ref and gpgme_trust_item_unref
    (the gpgme_trust_item_release alias for the latter is deprecated).
 
  * Keys are not cached internally anymore, so the force_update argument
    to gpgme_get_key has been removed.
 
  * GpgmeKey objects have now directly accessible data so the
    gpgme_key_get_string_attr, gpgme_key_get_ulong_attr,
    gpgme_key_sig_get_string_attr and gpgme_key_sig_get_ulong_attr
    functions are deprecated.  Also, gpgme_key_release is now
    deprecated.  The gpgme_key_get_as_xml function has been dropped.
 
  * Because all interfaces using attributes are deprecated, the
    GpgmeAttr data type is also deprecated.
 
  * The new gpgme_op_keylist_result function provides detailed
    information about the result of a key listing operation in
    a GpgmeKeyListResult object.
 
  * Now that each function comes with its own result retrieval
    interface, the generic gpgme_get_op_info interface is not useful
    anymore and dropped.
 
  * The type and mode of data objects is not available anymore.
 
  * Interface changes relative to the 0.4.0 release:

 Noteworthy changes in version 0.3.11 (2002-09-20)
 -------------------------------------------------
 
  * Bug fixes.
 
 Noteworthy changes in version 0.3.10 (2002-09-02)
 -------------------------------------------------
 
  * Setting the signing keys for the CMS protocol does now work.
 
  * The signers setting is honoured by gpgme_op_edit.
 
 Noteworthy changes in version 0.3.9 (2002-08-21)
 ------------------------------------------------
 
  * A spec file for creating RPMs has been added.
 
  * An experimental interface to GnuPG's --edit-key functionality is
    introduced, see gpgme_op_edit.
 
  * The new gpgme_import_ext function provides a convenient access to
    the number of processed keys.
 
  * Interface changes relative to the 0.3.8 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 GpgmeStatusCode			NEW
 GpgmeEditCb			NEW
 gpgme_op_edit_start		NEW
 gpgme_op_edit			NEW
 gpgme_op_import_ext		NEW
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Noteworthy changes in version 0.3.8 (2002-06-25)
 ------------------------------------------------
 
  * It is possible to use an outside event loop for the I/O to the
    crypto engine by setting the I/O callbacks with gpgme_set_io_cbs.
 
  * Interface changes relative to the 0.3.6 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 GpgmeIOCb			NEW
 GpgmeRegisterIOCb		NEW

 Noteworthy changes in version 0.3.6 (2002-05-03)
 ------------------------------------------------
 
  * All error output of the gpgsm backend is send to the bit bucket.
 
  * The signature verification functions are extended.  Instead of
    always returning GPGME_SIG_STATUS_GOOD, the functions new codes for
    expired signatures.  2 new functions may be used to retrieve more
    detailed information like the signature expiration time and a
    validity information of the key without an extra key looking.
 
  * The current passphrase callback and progress meter callback can be
    retrieved with the new functions gpgme_get_passphrase_cb and
    gpgme_get_progress_cb respectively.
 
  * Interface changes relative to the 0.3.5 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_get_passphrase_cb		NEW
 gpgme_get_progress_cb		NEW
 GpgmeDataEncoding               NEW
 gpgme_data_set_encoding         NEW
 gpgme_data_get_encoding         NEW
 GPGME_SIG_STAT_GOOD_EXP         NEW
 GPGME_SIG_STAT_GOOD_EXPKEY      NEW
 gpgme_op_verify                 CHANGED: Returns more status codes.
 GPGME_ATTR_SIG_STATUS           NEW
 gpgme_get_sig_string_attr       NEW
 gpgme_get_sig_ulong_attr        NEW
 gpgme_get_protocol              NEW
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Noteworthy changes in version 0.3.5 (2002-04-01)
 ------------------------------------------------
 
  * gpgme_op_encrypt can be called with RECIPIENTS being 0.  In this
    case, symmetric encryption is performed.  Note that this requires a
    passphrase from the user.
 
  * More information is returned for X.509 certificates.
 
  * Interface changes relative to the 0.3.4 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_op_encrypt		EXTENDED: Symmetric encryption possible
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Noteworthy changes in version 0.3.4 (2002-03-04)
 ------------------------------------------------
 
  * gpgme_op_encrypt does now fail with GPGME_Invalid_Recipients if
    some recipients have been invalid, whereas earlier versions
    succeeded in this case.  The plaintext is still encrypted for all valid
    recipients, so the application might take this error as a hint that
    the ciphertext is not usable for all requested recipients.
    Information about invalid recipients is available with gpgme_get_op_info.
 
  * gpgme_op_verify now allows to pass an uninitialized data object as
    its plaintext argument to check for normal and cleartext
    signatures.  The plaintext is then returned in the data object.
 
  * New interfaces gpgme_set_include_certs and gpgme_get_include_certs
    to set and get the number of certifications to include in S/MIME
    signed messages.
 
  * New interfaces gpgme_op_encrypt_sign and gpgme_op_encrypt_sign_start
    to encrypt and sign a message in a combined operation.
 
  * New interface gpgme_op_keylist_ext_start to search for multiple patterns.
 
  * gpgme_key_get_ulong_attr supports the GPGME_ATTR_EXPIRE attribute.
 
  * Interface changes relative to the 0.3.3 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_op_encrypt		CHANGED: Can fail with GPGME_Invalid_Recipients
 gpgme_op_verify			EXTENDED: Accepts uninitialized text argument
 gpgme_key_get_ulong_attr	EXTENDED: Supports GPGME_ATTR_EXPIRE
 gpgme_set_include_certs		NEW
 gpgme_get_include_certs		NEW
 gpgme_op_encrypt_sign		NEW
 gpgme_op_encrypt_sign_start	NEW
 gpgme_op_keylist_ext_start	NEW
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Noteworthy changes in version 0.3.3 (2002-02-12)
 ------------------------------------------------
 
  * Fix the Makefile in jnlib.
 
  * Fix the test suite (hopefully).  It should clean up all its state
    with `make check' now.
 
 
 Noteworthy changes in version 0.3.2 (2002-02-10)
 ------------------------------------------------
 
  * Remove erroneous dependency on libgcrypt in jnlib.
 
 
 Noteworthy changes in version 0.3.1 (2002-02-09)
 ------------------------------------------------
 
  * There is a Texinfo manual documenting the API.
 
  * The gpgme_set_keylist_mode function returns an error, and changed
    its meaning.  It is no longer usable to select between normal and
    fast mode (newer versions of GnuPG will always be fast), but
    selects between local keyring, remote keyserver, or both.
    For this, two new macros are defined, GPGME_KEYLIST_MODE_LOCAL
    and GPGME_KEYLIST_MODE_EXTERN.  To make it possible to modify the
    current setting, a function gpgme_get_keylist_mode was added to
    retrieve the current mode.
 
  * gpgme_wait accepts a new argument STATUS to return the error status
    of the operation on the context.  Its definition is closer to
    waitpid() now than before.
 
  * The LENGTH argument to gpgme_data_new_from_filepart changed its
    type from off_t to the unsigned size_t.
 
  * The R_HD argument to the GpgmePassphraseCb type changed its type
    from void* to void**.
 
  * New interface gpgme_op_trustlist_end() to match
    gpgme_op_keylist_end().
 
  * The CryptPlug modules have been renamed to gpgme-openpgp and
    gpgme-smime, and they are installed in pkglibdir by `make install'.
 
  * An idle function can be registered with gpgme_register_idle().
 
  * The GpgSM backend supports key generation with gpgme_op_genkey().
 
  * Interface changes relative to the 0.3.0 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_data_new_from_filepart	CHANGED: Type of LENGTH is size_t.
 GpgmePassphraseCb               CHANGED: Type of R_HD is void **.
 gpgme_wait                      CHANGED: New argument STATUS.
 gpgme_set_keylist_mode          CHANGED: Type of return value is GpgmeError.
                                 The function has a new meaning!
 gpgme_get_keylist_mode          NEW
 GPGME_KEYLIST_MODE_LOCAL        NEW
 GPGME_KEYLIST_MODE_EXTERN       NEW
 gpgme_op_trustlist_next		NEW
 GpgmeIdleFunc                   NEW
 gpgme_register_idle             NEW
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Noteworthy changes in version 0.3.0 (2001-12-19)
 ------------------------------------------------
 
  * New interface gpgme_set_protocol() to set the protocol and thus the
    crypto engine to be used by the context.  Currently, the OpenPGP
    and the CMS protocols are supported.  They are specified by the new
    preprocessor symbols GPGME_PROTOCOL_OpenPGP and GPGME_PROTOCOL_CMS.
    A new context uses the OpenPGP engine by default.
 
  * gpgme_get_engine_info() returns information for all crypto engines
    compiled into the library.  The XML format has changed.  To
    reliably get the version of a crypto engine, the <version> tag
    after the appropriate <protocol> tag has to be looked for.
 
  * New interface gpgme_engine_check_version(), obsoleting
    gpgme_check_engine().  Check the version of all engines you are
    supporting in your software.
 
  * GpgmeKey lists the user ids in the order as they are returned by
    GnuPG, first the primary key with index 0, then the sub-user ids.
 
  * New operation gpgme_op_decrypt_verify() to decrypt and verify
    signatures simultaneously.
 
  * The new interface gpgme_op_keylist_end() terminates a pending
    keylist operation.  A keylist operation is also terminated when
    gpgme_op_keylist_next() returns GPGME_EOF.
 
  * GPGME can be compiled without GnuPG being installed (`--with-gpg=PATH'),
    cross-compiled, or even compiled without support for GnuPG
    (`--without-gpg').
 
  * GPGME can be compiled with support for GpgSM (GnuPG for S/MIME,
    `--with-gpgsm=PATH').  It is enabled by default if the `gpgsm' is found
    in the path, but it can also be compiled without support for GpgSM
    (`--without-gpgsm').
 
  * CryptPlug modules for GPGME are included and can be enabled at
    configure time (`--enable-gpgmeplug').  There is one module which
    uses the GnuPG engine (`gpgmeplug') and one module which uses the
    GpgSM engine (`gpgsmplug').
 
  * Interface changes relative to the latest 0.2.x release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 gpgme_key_get_as_xml		CHANGED: Sub-user ids reversed in order.
 gpgme_key_get_string_attr	CHANGED: User ids reversed in order.
 gpgme_key_get_ulong_attr	CHANGED: User ids reversed in order.
 gpgme_get_engine_info		CHANGED: New format, extended content.
 gpgme_engine_check_version	NEW
 gpgme_decrypt_verify_start	NEW
 gpgme_decrypt_verify		NEW
 gpgme_op_keylist_next		NEW
 gpgme_set_protocol		NEW
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 
 Noteworthy changes in version 0.2.3 (2001-09-17)
 ------------------------------------------------
 
  * New function gpgme_get_op_info which can be used to get the micalg
    parameter needed for MOSS.
 
  * New functions gpgme_get_armor and gpgme_get_textmode.
 
  * The usual bug fixes and some minor functionality improvements.
 
  * Added a simple encryption component for MS-Windows; however the
    build procedure might have some problems.
 
 
 Noteworthy changes in version 0.2.2 (2001-06-12)
 ------------------------------------------------
 
  * Implemented a key cache.
 
  * Fixed a race condition under W32 and some other bug fixes.
 
 
 Noteworthy changes in version 0.2.1 (2001-04-02)
 ------------------------------------------------
 
  * Changed debug output and GPGME_DEBUG variable (gpgme/debug.c)
 
  * Handle GnuPG's new key capabilities output and support revocation
    et al. attributes
 
  * Made the W32 support more robust.
