this exact case is fixed in VS-Desktop-3.3.90.12-Beta
Adding further UIDs and making more certifications still works, too.

Very likely this bug exists since 2017 when support for promotion of local certifications to exportable certifications was added.

Fixed in gpgmepp for gpd5x. I think for VSD 3.3 we'll add a patch to gpg4win.

Well, I could not reproduce this at any time but tested decryption with long file paths to be sure nothing broke and it worked fine.

Fixed. If high-contrast is active then tool tips now use the same colors as buttons (e.g. white text on black for Kontrast No. 1).

Note: one of my patches makes gpgpass freeze when changing the users that can decrypt a certain folder (might not always be reproducible). This is caused by a Qt bug fixed with https://codereview.qt-project.org/c/qt/qtbase/+/638159

With the above patch for breeze the toolbar and the configuration dialog title now also look correct in high-contrast mode.

ah, sorry then, i haven't tested multistore/-user yet. i just assumed, it would switch the tree root.

If the password store root folder would be included in the tree, it would be possible to show all configured stores simultanously (e.g. with an additional name attribute in the store configuration). On the other hand, a conscious decision to switch the profile might be preferable to prevent user mistakes and over-the-shoulder information leaks.

The wrong/inconsistent coloring of the icons has been fixed.

After T7587: Kleopatra: High contrast mode isn't respected anymore was fixed this is what the buttons look like in Gpg4win 5:

Fixed. There are still some problems with the icons but those will be dealt with in a separate subticket of T6932: Icons, darkmode and stuff.

kleopatrarc, kleopatrastaterc, klanguageoverriderc, libkleopatrarc, and kxmlgui5/kleopatra/kleopatra.rc are now copied from the old location used by Gpg4win 4.4/VSD 3.3 (%APPDATA%/kleopatra) to the new location used by Gpg4win 5 (%GNUPGHOME%/kleopatra) if they do not yet exist at the new location. This is also logged.

It seems that High Contrast mode is completely ignored with Qt 6/KF6 (at least with Breeze and the built-in default style).

We decided on "Close window automatically on success". (German: "Fenster bei Erfolg automatisch schließen")

The migration of the group config file works again.

BTW, do we really need a C++ API for this? Might make sense due to the need for a context.

I guess this is done if QT6 versions have a pinentry?

This does not work as expected.
Import tabs still always have the default layout, regarding the width. The columns shown are kept from the previous tab, though.

5.0Beta:145: OK and works, both for signing and encryption
