A new CSV importer & exporter, thanks to Rumo:

- Shows a preview based on the selected field separator.
- Column mapping includes field text for reference.
- Multiple decks and notetypes can now be imported/exported at once, as columns can be mapped to deck or notetype name.
- Supports exporting and importing a unique identifier for a note, to use instead of a matching first field. This removes the need for the 'add note id' add-on.
- Extends the header syntax so that files can specify metadata such as the desired field separator, and the mapping of fields.
- The new functionality is not enabled by default, and can be enabled with a checkbox in the preferences screen. This also enables
the new apkg import/export code introduced in 2.1.52. If you use the Special Fields add-on, you will need to disable this option
in order to use the add-on.

- Fixed Anki needing to close when invalid modification times encountered by the browser on Windows.

- 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.

- 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](https://docs.ankiweb.net/misc.html#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.

If updating from Anki 2.1.49 or below, please see the [2.1.50 change notes](https://github.com/ankitects/anki/releases/tag/2.1.50) first.

- Reviews in the V3 scheduler can now optionally be sorted by relative overdueness (thanks to Abdo).

Fixes:

- Anki now closes the Browse screen before full sync or colpkg import/export, so it doesn't show errors.
