With VS-Desktop-3.1.90.277-Beta the generated key is the default RSA 3072.

For an OpenPGP group it looks now like this:

When testing with the viktor-gnupg testcertificate I get the new warning message instead of the not very helpful "no name" error in 3.1.26.
But it takes at least 30 seconds to get to that message (the error message in 3.1.26 came up much faster). And when acknowledging the warning it again takes almost as long as before until the message is sent. And in 2 out of 3 tries the Compose Window remained open, so that it looked like the message was not send. Clicking again on Send did not make anything happen, though. And checking the mailbox showed that the mail was sent already.

works. "archive (1).tar.gpg" is now the suggestion on Windows, too. Tested with VS-Desktop-3.1.90.267-Beta

ok, then I'll add the tag for the VSD release after the upcoming one. It is of course relevant for Gpg4win also, but we do not have a dedicated workboard for that (at least not yet)

The nonfunctonal "no date" is gone now in VS-Desktop-3.1.90.267-Beta

But I wonder if we should not address https://dev.gnupg.org/T6683#176429, the text there is not changes in this Beta version.

In GnuPG-VS-Desktop-3.1.90.267-Beta-Standard it works, aside from T6805:
You do not get the new "no x509" message wrongly any more even when quickly sending a mail after restart of Outlook.
But it correctly appeares if no X509 is available.
And the message is configurable via the registry setting HKLM/HKCU \Software\GNU\GpgOL\smimeNoCertSigErr (although I do not know how to add line breaks there, but that is not important).

with VS-Desktop-3.1.90.267-Beta when trying to send a secured mail to the expired Berta X509 testkey I get the confirmation dialog but now the OK button is greyed out:

So should we at the moment only change our backup/migration recommendations? Add %LOCALAPPDATA%/kleopatra and %LOCALAPPDATA%/*rc to the backup?

for comparison, the command without compliance enabled:

On Windows, the notifications are currently configured in kleopatra.kmessagebox, or more accurately, the wish not to notify is configured there:

Works, the confirmation is asked in all 3 cases.

It works for the standard use case where we have keys with one user ID.

For comparison, this is the debugview output if I don't give the passwort on import of a X.509 certificate, were the ü is displayed correctly:

with VS-Desktop-3.1.90.258-Beta the ü is still broken for "Zeitüberschreitung" in the error window which occurs in the context of keytocard:

This may be related to the output PIN retry counter : 3 0 3, i.e. the PUK counter is 0. No idea what this means.

as this really bugs me, I raise the prio.
And add the Kleo tag, as Werner said it might be that Kleopatra is responsible.

works with VS-Desktop-3.1.90.258-Beta

With VS-Desktop-3.1.90.258-Beta I ran again into the last issue with "Wrong PIN". I had not realized that I had entered the PIN wrong before (as you have to enter the PIN several times anyway when generating a new key on a card and you do not get an error message on wrong PIN but instead only a new pinentry window...).

works

with VS-Desktop-3.1.90.258-Beta, CSR creation is now greyed out for RSA2048, while it is offered and works for other algorithms

CSR creation works now (tested with VS-Desktop-3.1.90.258-Beta, Yubikey and OpenPGP card)

hmm, almost. With VS-Desktop-3.1.90.258-Beta I do not get an error any more, a key is generated. But the "vaild until" date is off by one day, it is one day later as the one given at key generation.

works, the secret part is now imported, too, tested with VS-Desktop-3.1.90.258-Beta

works: my brainpool X509 testcertificate is shown as compliant

For the VSD branch it works, VS-Desktop-3.1.90.258-Beta

In VS-Desktop-3.1.90.258-Beta it is "no space left on device" now in the encrypt/verify window.

At the moment we have a green background for the results of a decryption and/or verification, if it was successful.
This does not work with high contrast mode.

and it is also confusing that you can choose the key for signing in Kleopatra, it is displayed with a green check mark but then you run into an error:

yes, fixed

The original issue was to unclear to analyse and it was likely meanwhile fixed. For the other issue see the follow up ticket.

The debug/workaround option works: When the option is checked, opening the msg file will not change its date.

With VS-Desktop-3.1.90.246-Beta I can not import the secret part of the edward.tester@demo.gnupg.com.p12 Testkey (ECC brainpool).
I do not see any error message.

works: installed VS-Desktop-3.1.90.246-Beta with

it was decided to write the encrypted archive with ending .part and only rename it at the end. In this way the users can't think they have a valid encrypted archive

Well I have looked at this ticket and posted a comment. We should talk about if there is anything left to do or not. I suspect that the gpg side is done and I should open one (or probably better several) ticket(s) for the kleopatra side.

works now with VS-Desktop-3.1.90.246-Beta

The error message in Kleo is now (with VS-Desktop-3.1.90.246-Beta) "Broken pipe". But in the linked error protocol you can find the gpg error message "no space left on device". So I would find this message acceptable.

As what I see is similar as what Andre saw, I'll describe it here. Please check if this is relevant.
After the above mentioned Ticket was resolved, I tried the exact same encryption in Kleopatra on the same Test-VM.
