2.1.52

If updating from Anki 2.1.49 or below, please see the 2.1.50 change notes first.

Editor Improvements

• Ctrl/Cmd+A in tag editing area now selects all tags (thanks to BlueGreenMagick).
• Fixed backspace sometimes removing multiple images at once (thanks to Henrik).
• Fixed copying and pasting MathJax on Windows (Qt6).
• Fixed handling of < and > symbols in MathJax (thanks to Henrik).
• Fixed intermittent editor loading failures when add-ons have injected a large amount of code.
• Fixed pasting of local files of unsupported types that contain spaces (thanks to Abdo).
• Fixed some formatting being lost when copying between fields on Windows (Qt6).
• Fixed various issues with tag editing (thanks to BlueGreenMagick and Henrik).
• Pressing tab on the last field now moves focus to tag area (thanks to Henrik).
• Reduce size of editor buttons on Windows/Linux (thanks to Henrik).
• Tags copied from the tag editor are no longer joined together when pasted into the add tags/remove tags dialogs (thanks to Henrik).
• The Qt5 Mac build now caps tag autocomplete matches to 10, as showing more is extremely slow in the old toolkit version.

Other Improvements

• Update Qt to 6.3.0, which fixes slow loading of large images, and inertial scrolling on macOS.
• Fixed an error when previewing cards and selecting multiple cards (thanks to Rumo).
• Fixed Anki needing to close when invalid modification times encountered by the browser on Windows.
• Fixed colpkg imports not being cancellable (thanks to Rumo).
• Fixed current working directory changing on apkg export.
• Fixed custom browser font not being honored (Qt6).
• Fixed custom study applying the previously-input limit, instead of the current one.
• Fixed due graph showing wrong date for review cards in a filtered deck with rescheduling disabled.
• Fixed grey background in type answer text + dark mode (thanks to Matthias).
• Fixed v3 scheduler allowing one extra card when review limit reached (thanks to Rumo).
• Lists on cards are now aligned to the left by default (thanks to Matthias).
• Removed the highlight on the Show Answer and Good buttons.
• Reset page zoom when moving between different screens.
• The Qt6 Linux build now defaults to X11/XWayland instead of Wayland due to some remaining issues; you can force-enable Wayland with ANKI_WAYLAND=1.

For Developers

• The field_filter hook can now check if it's running for the question or answer side (thanks to Abdo).
• Added a av_player_will_play_tags hook (thanks to Abdo).
• Make it easier to search in fields programmatically (thanks to Abdo).

New Apkg Import/Export

This build also includes a new implementation of apkg importing and exporting, thanks to Rumo. Some advantages:

• Undo/redo is now supported.
• Faster imports (especially for decks with a lot of note content).
• Support for older clients can be optionally disabled, which results in smaller
  apkg files, and faster imports.
• Flags are removed when scheduling is excluded.

The new functionality is hidden behind a feature flag, and not active by default.
You can try it out by using mw.pm.set_new_import_export(True) in the debug console.
To revert to the old behaviour, replace True with False.

Things to note:

• This is new code that has received limited testing so far, so please use File>Create Backup before trying it out.
  Any testing/feedback you can provide would be appreciated.
• While active, it is not currently possible to import/export files other than apkg/colpkg.
• The Special Fields add-on will not work while this functionality is enabled.
