Platform-Specific Changes


  • Windows 10 or 11 is required. If you are still using Windows 7 or 8, 2.1.49 is
    the last build that will install on your system.


  • Anki now supports Apple Silicon natively. If you're on a newer Mac with an M1
    processor, pick the qt6-apple download for better performance and battery
  • The Qt6 x86 build requires macOS 10.14.4
  • The Qt5 x86 build requires macOS 10.13.4.


  • The Linux builds need zstd to decompress, eg:
sudo apt install zstd
tar xaf anki-2.1.50-linux-qt6.tar.zstd
  • The packaged version requires glibc 2.27 or later.
  • A wheel is now provided for ARM64 Linux, and requires glibc 2.31 or greater. See
    this page for instructions on using it.
  • Both Fcitx4 and Fcitx5 support is now bundled.


Please see the notes for your platform:

Scheduler Changes

The V1 scheduler is no longer supported. If you have not yet updated to V2 or
V3, you will be prompted to update when you attempt to review cards in 2.1.50.

This release includes a number of improvements to the V3 scheduler, mostly
thanks to Rumo:

  • Intermediate deck limits now affect their children. Please see the scheduler
    for more
  • When new cards are answered, Anki now records their original position. When you later
    export a shared deck without scheduling, the original positions will be restored.
  • The Forget action now gives you options to restore the original card position,
    and to reset the card's lapse and repetition counters.
  • The gathering and sorting of new cards has been reworked, trading a little performance
    for more intuitive behaviour:
    • It is now possible to sort notes or cards randomly at gather time, ensuring a random
      selection is taken from all available new cards.
    • The gather order and sort order options have been simplified, but should offer the same
      functionality as before. Please check your deck options after upgrading, as some users
      may need to adjust their display order settings to match what they were using before.
  • The overview screen now shows how many cards will be buried.
  • Added a separate option to control burying of interday learning siblings.
  • Fixed interday learning siblings not being buried during review, causing them
    to reappear later after actions like an edit.
  • If you have more than 2 learning steps, after the first step, Hard repeats the previous
    delay, instead of being the average of the previous and next step.
  • When a Hard learning step exceeds a day, it is now rounded to a full day, so the
    delay does not vary depending on the time of day you answer.
  • Fuzz is applied more evenly now, especially with smaller intervals.
  • Fixed new cards not decrementing the review limit, which could lead to
    more new cards appearing after the review limit was reached.
  • Review cards and new cards are now interspersed more evenly.
  • When using Custom Study to extend deck limits in the V3 scheduler, parent/child
    limits of the selected deck are no longer adjusted.

Editor Changes

Most of these changes are thanks to Henrik.

  • A redesigned editing area, and a redesigned tag editor.
  • MathJax has a live preview.
  • HTML source and rendered text can be viewed at the same time.
  • The HTML editor now matches the current Anki theme.
  • Images can be resized within the editor.
  • Fields can now have an optional description/tooltip assigned to them (thanks
    to Matthias, Henrik & Rumo).
  • The "remove formatting" button now offers a choice of what to remove.
  • Adjust color picker shortcut, and apply color when different color selected.
  • Reduced editor button size on Windows/Linux (thanks to Matthias).
  • Fixed IME input after pressing tab.
  • Fixed media files not being inserted at cursor position on Windows.
  • Cloze shortcut correctly positions cursor.
  • Added a separate cloze button to repeat the current cloze.
  • Lots of behind-the-scenes changes and fixes. Because of the extensive changes,
    some add-ons that modify the editing screen will have broken (see the
    developers section below)

New Features

  • Anki will now switch to day or night mode automatically depending on your
    system settings. You can force day or night mode in the Preferences screen.
    (thanks in large part to Rumo).
  • Reworked backup handling (mostly thanks to Rumo):
    • Backups are created much faster than they were previously.
    • Anki can now create backups periodically. The default is every 30 minutes; you can adjust this in the preferences screen.
    • There are new options in the preferences to control the number of daily, weekly and
      monthly backups you'd like to retain.
    • The File menu now has an option to create a backup immediately.
    • Because the backup storage format has changed, backups created with 2.1.50 will not be
      importable into older Anki versions.
  • Reworked .colpkg import/export (thanks to Rumo):
    • When exporting, you can optionally target Anki 2.1.50+. When doing so,
      imports and exports are faster, and media files will be compressed, but the
      resulting .colpkg will not be readable by older Anki clients.
    • Collections are now checked for corruption when importing.
  • An option to ignore accents in searches by default has been added to
    preferences screen (thanks to Abdo).
  • The Card Info screen now updates automatically as you change to a different
    card (thanks to Rumo).
  • Added a View menu to the main window and browse window (thanks to Rumo). The
    view menu provides options to zoom in and out, and to toggle a full screen
    mode. Due to technical issues, the full screen mode is not currently available
    on Windows when graphics acceleration is enabled.
  • A new TTS tag format that allows you to combine extra text and multiple
    fields, such as [anki:tts lang=en_US]Here is {{Field1}} and {{Field2}}[/anki:tts] (thanks to Rumo). There are no plans to deprecate the
    old TTS syntax - either can be used.
  • Added an option to add/remove sidebar tag to selected notes (thanks to Rumo).
  • Be smarter about mapping existing text to new fields when switching notetypes in the Add screen (thanks to Abdo).
  • Apkg files can now be dragged on the main window to import them (thanks to Abdo).
  • Added a "Create Copy" option in the browse screen and review screen, to copy
    selected note's contents into the Add window (thanks to Rumo).
  • You can now search for tags by regular expression (thanks to Rumo). One use
    for this is locating notes that are tagged with a parent tag, while not matching
    ones tagged with parent::child: tag:re:^parent$.
  • When switching Anki versions, an add-on update check is run on startup (thanks to Rumo).
  • Make links with target=_blank work (thanks to Danish).
  • Added "Forget Card" action to review screen (thanks to Araceli).
  • Added Belarusian and Odia to available languages in the preferences.
  • Added a silent option (/s) for the Windows uninstaller (thanks to Patric).
  • Added tooltips to some browser columns (thanks to Rumo).

  • Change cards/notes toggle to Ctrl/Cmd+Alt+T to avoid conflict on macOS.
  • Changed the "Previous Card Info" shortcut to avoid a conflict with language input.
  • Colpkg imports now always require a full sync.

For Developers

  • Anki now requires Python 3.9.
  • Anki contains some compatibility shims that should allow many add-ons written
    for PyQt5 to work with PyQt6 as well (thanks to Aristotelis). These shims will
    not remain forever, so it is recommended that you update your add-ons to be
    compatible with Qt6 without shims. The two main breakages are the renaming of
    PyQt5 to PyQt6 (you can support both by importing from aqt.qt instead), and
    the requirement that enums are
  • If you’re using Qt Designer to generate UI files, the Qt5 and Qt6 versions
    need to be generated and bundled separately if you want to support both at once.
  • PyQt6 does not support the Qt resource system (pyrcc was removed), so Anki now
    uses a different approach, and urls like :/icons/foo.jpg should become
  • Henrik has spent a lot of time working out how to smoothly provide an API for
    the editor, and investigating how we can provide types to make targeting the API
    easier. This has required a number of refactorings, and some add-ons that were
    accessing the editor will have broken in this update. While the code is
    not set in stone yet, hopefully we're getting there. An example of using the
    latest API is available here:
  • The way Anki is packaged has changed. Most of the standard library should be
    available now. If you notice any problems importing standard libraries that
    previously worked, please let us know.
  • The aqt package no longer depends on PyQt, as either version 5 or 6 is supported.
    You can specify the major version you want when installing - eg pip install 'aqt[qt6]'
  • manifest.json now supports a 'homepage' argument (thanks to Abdo)
  • mw.progress.timer() should now be passed a parent argument, as the
    previous default of using mw prevents the timers from being freed after they
    are no longer active. If you want a permanent timer, pass mw in as the parent.
  • Improved Python code completion/type handling in VS Code (thanks to Rumo).
