# 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 `&` 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](/manual/misc#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.

## Release Candidate 1

Build a989e508 / 2022-04-25.

* Update Qt to 6.3, which fixes slow loading of large images, and inertial
  scrolling on macOS.
* 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).
* 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).
* The Qt6 Linux build now defaults to X11/XWayland instead of Wayland due to
  some [remaining issues](https://github.com/ankitects/anki/issues/1767); you
  can force-enable Wayland with ANKI\_WAYLAND=1.
