# Changes in 2.1.52

## Release Candidate 3

Build ab1c2395 / 2022-05-10.

The Qt 6.3.1 release we were waiting on has been delayed by a month, so 2.1.52 is now expected to release as stable within the next week, if no important issues come up.

Editor improvements:

• Ctrl/Cmd+A in tag editing area now selects all tags (thanks to BlueGreenMagick).
• 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).
• Fixed &amp; showing up when using & in MathJax (thanks in part to Henrik).
• Fixed various issues with tag editing (thanks to BlueGreenMagick and Henrik).

Other fixes:

• Fixed scrollbars showing in bottom area of review screen (thanks to Matthias).
• Fixed v3 scheduler allowing one extra card when review limit reached (thanks to Rumo).
• Fixed Anki needing to close when invalid modification times encountered by the browser on Windows.
• Fixed new importer failing to import a subdeck export (thanks to Rumo).
• Improve progress feedback when using the new importing and exporting code.
• New import code supports .zip filenames, and runs on drag/drop + file double-click cases as well.

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).

## Release Candidate 2

Build 63f05b2b / 2022-05-02.

Bugfixes/tweaks:

• The Qt5 Mac build now caps tag autocomplete matches to 10, as showing more is extremely slow in the old toolkit version.
• Fix custom study applying the previously-input limit, instead of the current one.
• Fix an error when previewing cards and selecting multiple cards (thanks to Rumo).
• Removed the highlight on the Show Answer and Good buttons.
• Make it easier to search in fields programmatically (thanks to Abdo).

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 export files other than apkg/colpkg.
• The Special Fields add-on will not work while this functionality is enabled.

• List text is now aligned to the left by default (thanks to Matthias).
• Reset page zoom when moving between different screens.
• Fixed backspace sometimes removing multiple images at once (thanks to Henrik).
• Fixed colpkg imports not being cancellable (thanks to Rumo).
• Fixed copying and pasting MathJax on Windows (Qt6).
• Fixed current working directory changing on apkg export.
• Fixed custom browser font not being honored (Qt6).
• Fixed due graph showing wrong date for review cards in a filtered deck with rescheduling disabled.
• Fixed some formatting being lost when copying between fields on Windows (Qt6).
• Fixed grey background in type answer text + dark mode (thanks to Matthias).
• Fixed handling of < and > symbols in MathJax (thanks to Henrik).
