Packaged Builds

Betas are posted on https://github.com/ankitects/anki/releases.

Via PyPI/pip

If you have a local Python 3.9+ installation, you can also install beta builds directly with pip.

Anki will be installed in a local Python folder called 'pyenv'.

Mac (both Intel/Apple), and Linux (x86_64)

$ python3 -m venv pyenv
$ pyenv/bin/pip install --upgrade pip
$ pyenv/bin/pip install --upgrade --pre 'aqt[qt6]'
$ pyenv/bin/anki

Repeat the last step if you wish to start the same Anki version again.
Repeat the last two steps to update to the latest beta and start it.

Linux (ARM)

As there are no PyQt packages on PyPI for Linux/ARM, you will need to have your distro's PyQt5 packages already installed. Eg on Debian 12:

$ sudo apt install python3-pyqt6.qt{quick,webengine,multimedia} python3-venv

Or on Fedora:

$ sudo dnf install python3-qt5-webengine

Then run the following:

$ python3 -m venv --system-site-packages pyenv
$ pyenv/bin/pip install --upgrade pip
$ pyenv/bin/pip install --upgrade --pre aqt
$ pyenv/bin/anki

Repeat the last step if you wish to start the same Anki version again.
Repeat the last two steps to update to the latest beta and start it.

Windows

c:\> python -m venv \pyenv
c:\> pyenv\scripts\pip install --upgrade pip
c:\> pyenv\scripts\pip install --upgrade --pre aqt[qt6]
c:\> pyenv\scripts\anki

Repeat the last step if you wish to start the same Anki version again. Repeat the last two steps to update to the latest beta and start it.

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.

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).

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; you can force-enable Wayland with ANKI_WAYLAND=1.

Changes in 2.1.51

Fixed stats PDF being illegible when saving in dark mode after scrolling down (thanks to Luka).
Use <b> and <i> formatting tags, instead of <strong> and <em>.
Fixed an issue with the search history when clicking on items in the sidebar (thanks to Rumo).
Anki now closes the Browse screen before full sync or colpkg import/export, so it doesn't show errors.

Release Candidate 1

Build 51a0641b / 2022-04-10.

Reviews in the V3 scheduler can now optionally be sorted by relative overdueness (thanks to Abdo).
Improve editor startup time, especially with many fields (thanks to Henrik).
Automatically re-enable disabled add-ons when user explicitly reinstalls them, and improve conflict handling (thanks to Aristotelis).
Fixed an issue that was breaking some add-ons when running on Windows without using anki-console.bat
Fixed card layout screen opening too wide if card template name was long (thanks to Sam).
Fixed full sync not being triggered when changing sort field.

Changes in 2.1.50

Build 26d40c3a / 2022-04-06.

The editing speedup change has been pushed back to 2.1.51 due to a bug.
For Qt6, the video driver now defaults to OpenGL on Windows/Linux, like earlier betas. The option in the preferences has been hidden again, and a new file introduced for adjusting behaviour: https://docs.ankiweb.net/platform/windows/display-issues.html#qt6

Release Candidate 3

Build c96ef8cd / 2022-04-05.

The editor loads faster now, especially with lots of fields (thanks to Henrik).

Fixed an error when importing some colpkg files from older Anki versions that contained media.
Fixed an issue with adding items to the editor toolbar from an add-on (thanks to Henrik).
Fixed cloze shortcut on Windows.
Fixed invalid HTML in field causing Anki to hang (thanks to Henrik).
Force decimal separator to be a period in the deck options, to work around blank boxes in the Qt6 build.
New cards no longer have their position changed by the Forget action when "restore position" is enabled, and the cards don't have an original position (thanks to Rumo).

Release Candidate 1

Build ebe33a99 / 2022-03-29.

Fixed a serious issue with repositioning/removing card templates in the card layout screen, that was present since beta 3 (thanks to Rumo for the fix).
Fixed "create cloze with same number" shortcut on Qt6/macOS (thanks to Henrik).
Fixed cursor sometimes not moving into MathJax editor, leading to accidental deletion (thanks to Henrik).
Colpkg imports now always require a full sync.
Fall back on regular file deletion when no recycling bin/trash folder is available on Linux.
Randomized card positions now start at 1, which avoids a corner case in filtered deck scheduling.
Rows with database inconsistencies in the browse screen now prompt you to use "check database" instead of saying they were deleted (thanks to Rumo).
The 'future due' graph no longer shows learning cards in a filtered deck as being due a long time ago.
When Anki encounters an issue with a card template, it now provides a link to a help page with more information (thanks to Rumo).

Beta 9

Build 4515c41d / 2022-03-21.

Fixed a serious issue with changing card numbers in Change Notetype that was present since beta 3. (thanks to Arthur for the reproduction steps).

The File menu now has an option to create a backup immediately.
When using Custom Study to extend deck limits in the V3 scheduler, parent/child limits of the selected deck are no longer adjusted (thanks to Rumo).
Fixed an error that could occur in the browser when switching profiles (thanks to Hikaru).
Improvements and optimizations to colpkg exports/imports (thanks to Rumo).

Beta 8

Build 02c580e4 / 2022-03-17.

Various fixes for .colpkg importing and exporting. We're reasonably confident the bugs have been ironed out at this point, but would appreciate you giving them a try and confirming the new code works well for you.
.colpkg files created with the previous beta will not be importable into this build. If you created a .colpkg file with beta 7 and need to recover data from it, please get in touch and we can help you out.
Fixed addMedia() call used by some add-ons (thanks to Henrik).

Beta 7

Build 02ba50f2 / 2022-03-15.

This release has been yanked due to bugs in colpkg imports. Please wait for the next beta.

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.
Various fixes for the editor (thanks to Henrik):
Allow longer maximum answer times in the deck settings (thanks to Bruce).
The custom study screen no longer (sometimes incorrectly) limits the amount you can extend the daily limits by.
Fix an intermittent error when building on Windows.

Beta 6

Build a495fbaa / 2022-03-09.

Reworked backup handling (thanks to Rumo):
- Backups are created much faster than they were previously, which allows Anki to close faster when you have a large collection, while still compressing the backups.
- There are new options in the preferences to control the number of daily, weekly and monthly backups you'd like to retain. Anki will keep all backups made in the last 48 hours, but avoids making more than one every 5 minutes when you're rapidly opening and closing your profile.
- Because the backup storage format has changed, backups created with 2.1.50 will not be importable into older Anki versions. Manually-exported colpkg files are still compatible with older Anki versions.
When exporting a shared deck with scheduling disabled, the original card position will be restored if it is available (thanks to Rumo).
The Forget action now gives you options to restore the original card position, and to reset the card's lapse and repetition counters (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$.
Added a silent option (/s) for the Windows uninstaller (thanks to Patric).
Fixed add-on config screen failing to show in bundled build.
Fixed buried counts being shown when v2 scheduler enabled.
Fixed MathJax sometimes being deleted when it wasn't visibly selected (thanks to Henrik).
Fixed newline shortcut in MathJax editor (thanks to Henrik).
Fixed shortcut/button to add a new tag (thanks to Henrik).
Fixed some parts of the media handling code matching more HTML tags than it should have (thanks to Brayan).
Fixes for the bury count on the overview screen (thanks to Rumo).

Beta 5

Build 3564ece6 / 2022-02-25.

Editor fixes, thanks to Henrik:

Fixed < and > not working correctly in the MathJax editor.
Fixed media files not being inserted at cursor position on Windows.
Cloze shortcut correctly positions cursor.
Adjust color picker shortcut, and apply color when different color selected.
Make it easy for add-ons to adjust the HTML editor theme.

Other changes:

Fixed the errors when using the preview button in the browser, and more work on memory leaks (thanks to Rumo).
Truncate deck names in the deck list if they are too long (thanks to Sachin).
Flags are undoable again, and should update correctly in the browser.
Hide the 'bury interday siblings' options when the V2 scheduler enabled.

Beta 4

Build 4ed499fb / 2022-02-23.

V3 scheduler changes, thanks to Rumo:

When new cards are answered for the first time, Anki will remember their original position, and it can be seen in the card info. An option to restore cards to their original position manually and on export will likely come in the next beta.
The overview screen now shows how many cards will be buried. Please report any inaccuricies, as it is possible a different approach will be needed.
Added a separate option to control burying of interday learning siblings. This is currently incorrectly shown when the V2 scheduler is enabled as well.
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.

Other new features:

The way bold/italics/etc is applied in the editor has been reworked to be more robust, thanks to Henrik. This has resulted in tweaks to the formatting button order, and the clear formatting button now lets you configure what formatting should be removed.
An option to ignore accents in searches by default has been added to preferences screen (thanks to Abdo).
Added a View menu to the main window and browse window (thanks to Rumo).

Bugfixes:

Added a "Learn" label to the learning counts in the deck list.
Fixed an error loading the old deck options screen when using Python 3.10.
Fixed an error when an installed TTS voice on Windows supported multiple languages (thanks to Rumo).
Fixed an error when exporting a collection with media files in it with very old modification dates (thanks to gnnoh).
Fixed junk appearing in the clipboard when copy/pasting on Windows, by rolling Qt back to the previous version.
Fixed newly-added deck not being selected in the Add screen (thanks to Hikaru).
Fixed sound failing to play after exporting a collection (thanks to Rumo and Kelciour).
Fixed various memory leaks (thanks to Rumo and Hikaru).
Flag changes no longer add an undo entry, which fixes some potential errors and unpredictable undo behaviour.
Reduced flicker when opening browser in night mode (thanks to Rumo).
Some behind-the-scenes code improvements (thanks to Sam).

For developers:

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.
Improved Python code completion/type handling in VS Code (thanks to Rumo).

Beta 3

Build 95dbf30f / 2022-02-10.

V3 scheduler changes, thanks to Rumo:

Intermediate limits are now respected. For example, if you have a deck tree of A>B>C>D, and click on B, then deck C is limited by deck B, and deck D is limited by both deck B and deck C. This is similar to the way the previous schedulers behaved, except the decks above the one you click on do not contribute to the limit.
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.
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.
Review cards and new cards are now interspersed more evenly.

Improvements to the editor, thanks to Henrik:

You can now use the keyboard left/right keys to move into/out of the MathJax editor.
The HTML editor now matches the current Anki theme.
Fixed an issue that could prevent image resizing.
Fixed IME input after pressing tab.
Fixed currently-focused field not updating contents after an undo operation or find&replace.
Fixed leading HTML comments being stripped by the HTML editor.
Lots of other behind-the-scenes changes (see the developers section below) and fixes.

New features:

Be smarter about mapping existing text to new fields when switching notetypes in the Add screen (thanks to Abdo).
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.
Apkg files can now be dragged on the main window to import them (thanks to Abdo).
"Create Copy" uses the current card's deck, and can be also accessed via shortcut from the review screen (thanks to Rumo)
Added Belarusian and Odia to available languages in the preferences.
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).

Fixes and other improvements:

Compression on automatic backups has been turned off, which can make Anki much faster to shut down with large collections (eg 7.9s->0.45s). Compression will likely come back in the future when we can integrate a more efficient compression library.
Add back the missing "Show Duplicates" link in the editor (thanks to Matthias and Henrik).
Added shortcut keys for creating lists and indentation (thanks to Rumo).
Behind-the-scenes improvements to the deck and notetype selectors (thanks to Sam).
Change cards/notes toggle to Ctrl/Cmd+Alt+T to avoid conflict on macOS.
Deck creation in the custom study screen has been reworked, and now supports undo properly (thanks to Rumo).
Don't show error when gsettings exists but does not have a GNOME theme set (thanks to Spooghetti420).
Don't show error when Windows color scheme setting is missing (thanks to qxo).
Filtered decks in 'order added' now sort by card template.
Fixed a number of issues with the preview window (thanks to Hikaru).
Fixed AltGr triggering Ctrl+Alt shortcuts on Windows (thanks to Rumo)
Fixed an error that could appear when clicking on the sidebar (thanks to qxo).
Fixed error shown when double-tapping answer buttons on the v3 scheduler.
Fixed external scripts being executed out of order (thanks to Hikaru).
Fixed field content sometimes spilling outside container (thanks to Hikaru).
Fixed flicker in review screen when referencing external js, and preload css files (thanks to Hikaru).
Fixed interday learning siblings not being buried during review, causing them to reappear later after actions like an edit.
Fixed new card position appearing as a date when cards were in preview (thanks to Abdo).
Fixed unwanted <div> being left behind when deleting field contents (thanks to Hikaru).
Hide "open new window" action in GNOME (thanks to Fusion future & Felipe)
Improve search highlight color in templates screen (thanks to Abdo).
Improved display of the card info screen (thanks to Rumo).
Improved localization of large numbers in the graphs, and various layout tweaks (thanks to Vova).
Performance improvements for searching through many fields with a wildcard search (thanks to Rumo).
Report correct count in timebox screen with v2 scheduler (thanks to Abdo).
Support Markdown inside HTML tags in config.md (thanks to Abdo).
The note: and card: searches no longer do a substring match (thanks to Rumo).
The calendar graph uses consistent coloring as years are changed (thanks to Ryan).
The top and bottom bars will no longer zoom in/out, but the main area and editors can be zoomed in and out (thanks to Rumo).
Tweaks to the sidebar icons (thanks to Henrik).
Updated translations - thanks as always to all the translators.
Use white menubar on Windows (thanks to Rumo).
Various behind-the-scenes fixes (thanks to Arthur).

Packaging changes:

The building of the Anki packages has been reworked. Everything should hopefully behave as before; if you notice any problems, please let us know.
Update to (Py)Qt 6.2.3.
Update mpv to 0.34 on Windows.
Fcitx5 support is now bundled with both the qt6 and qt5 Linux packages.
Drop the experimental arm64 Linux package.

Notes for developers:

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 again 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:

https://github.com/hgiesel/anki_new_format_pack/commits/master

Beta 2

Build db804d95 / 2021-12-09.

macOS:

The Apple Silicon build now supports recording, and is fully native - Rosetta is no longer required.
The Qt6 Intel build now has a minimum macOS requirement of 10.14.4.

Linux:

Fixed not being able to run Anki after running install.sh.
Added an experimental arm64 packaged build. PyQt and Qt are not included, so you need to link in your distro's version of PyQt5.15. For example, after untarring the file and changing into the top level directory with the 'anki' executable:
```
# eg Debian 11:
sudo apt install python3-pyqt5.{qtwebengine,qtmultimedia}
ln -sf /usr/lib/python3/dist-packages/PyQt5 lib/

# eg Fedora 34:
sudo dnf install python3-qt5-webengine
ln -sf /usr/lib64/python3.9/site-packages/PyQt5 lib/
```
You may also be able to use the above technique for switching the x86_64 builds to your system's PyQt version - just delete the PyQt5 or 6 folder before linking your system version in.
Fcitx users: this build includes libraries that may allow the Qt5 build to work with Fcitx. Please let us know if they work for you or not.

Features:

Added a "Create Copy" option in the browse screen, to copy selected note's contents into the Add window (thanks to Rumo).

Fixes:

Make scrollbars dark again in night mode (thanks to Hikaru).
Various improvements to right-to-left display (thanks to Abdo).
Fixed an error being shown when gathering new cards in descending position in the v3 scheduler.
Fixed unwanted height/width settings when copying images between fields (thanks to Henrik).
Reduced editor button size on Windows/Linux (thanks to Mathtias).
Support autoplay in audio tags again (thanks to Andreas).
Don't save window position when they're full screen, as Qt doesn't handle it well (thanks to Rumo).
Fixed the main window sometimes failing to load properly when Anki starts (which could lead to blank windows, a giant sync icon, etc).
Miscellaneous other fixes, thanks to Abdo, Matthias, TheFeelTrain and Arthur.

Beta 1

Build 43c41d76 / 2021-12-04.

Toolkit changes:

The packaged builds now come in separate Qt5 and Qt6 versions.
Qt6 is a recently-updated version of the toolkit. It fixes some issues that existed in Qt5, but it may introduce new problems. We recommend you try it first.
Qt5 is the graphics toolkit used to build previous Anki releases. If you find that Qt5 works for you and Qt6 does not, please let us know.

Windows:

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.

macOS:

There is now a native build for Apple Silicon. It currently does not support recording, and the audio playback still uses Intel binaries, so you will still need Rosetta installed. Only Qt6 is available for Apple Silicon.
The Qt6 x86 build requires macOS 10.14.
The Qt5 x86 build requires macOS 10.13.4.

Linux:

The Linux builds need zstd to decompress, eg:

sudo apt install zstd
tar axf anki-2.1.50-linux-qt6.tar.zstd

The x86 builds require glibc 2.27 or later.
A wheel is now provided for ARM64 Linux, and requires glibc 2.31 or greater. A packaged version is not currently possible.
No fcitx driver or gtk2 theme is bundled with the packaged builds at the moment.

Major editor changes, mostly thanks to Henrik:

A redesigned tag editor.
MathJax has a live preview.
HTML and rendered text can be viewed at the same time.
Images can be resized within the editor.
Fields can now have an optional description/tooltip assigned to them (thanks to Matthias, Henrik & Rumo).
Lots of behind-the-scenes changes. Because of the extensive changes, some add-ons that modify the editing screen will have broken.

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.
The V3 scheduler will be declared stable when 2.1.50 is released.
The V3 scheduler applies fuzz more evenly now, especially with smaller intervals (thanks to Rumo).
Fixed new cards not decrementing the review limit in V3, which could lead to more new cards appearing after the review limit was reached.
Fixed new cards not appearing in the correct order in the V3 scheduler.

Other 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).
The Card Info screen now updates automatically as you change to a different card (thanks to Rumo).
Added a shortcut to make Anki full screen (F11 or Cmd+Ctrl+F, thanks to Rumo).
Added tooltips to some browser columns (thanks to Rumo).
Added an option to add/remove sidebar tag to selected notes (thanks to Rumo).

Other improvements:

Improvements to the Change Notetype screen (thanks to Matthias).
Improved performance with large selections in the Browse screen (thanks to Rumo).
Fixed the deck list showing up blank in collections with many expanded decks.
Changed the "Previous Card Info" shortcut to avoid a conflict with language input.
Possible fix for intermittent UI glitch on initial startup (thanks to Evandro).
Flip sidebar location in RTL mode (thanks to Abdo).
Fix deck name not updating after deck/notetype renamed (thanks to Hikaru).
Fixed "tag duplicates" possibly operating on stale data (thanks to Ren).
The Add Cards screen will no longer allow accidental triggering of main window shortcuts when it is open on a Mac (thanks to Rumo).
Fixed incorrect card count in timebox after undo (thanks to Abdo).
Fixed quotation of "and" and "or" in search (thanks to Rumo).
Numerous other fixes and contributions, thanks to Rumo, Henrik, Abdo, Matthias, Evandro, Arthur, Soren, BlueGreenMagick, Yoshi, Jakub, Gesa, blue-putty, stopendy, and zjosua.

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 qualified.
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 icons:foo.jpg.
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)

Changes in 2.1.48

Release Candidate 2

Build 466d67ca / 2021-09-16.

Hide "Rename with Parents" for top-level items (thanks to Rumo).
"Add Field" action now correctly handles multi-word font names.
Fix newline being added when coloring text (thanks to Henrik).
Fix incorrect system font when running Anki in some non-English languages.
Fix learning count sometimes jumping to a large number in the v3 scheduler.
Fix console warning when playing audio (thanks to Evandro).
Another fix for Reposition command not working on buried/suspended cards.
Preserve focus when changing notetype in the Add screen.
Miscellaneous other fixes.

Changes in 2.1.47

WithShortcut is now also available.

Release Candidate 1

Build dffa38c4 / 2021-08-22.

Changes to the v3 scheduler:

Interday learning cards are included in the learning count again, instead of the review count.
Interday learning cards are still affected by the review limit. Interday learning cards are fetched first, then reviews, and finally new cards.
Filtered decks with rescheduling disabled now log reviews, so the reviews will appear in your graphs.
Added an option to sort reviews by ascending/descending ease.
Fixed an issue where an error message could appear after undoing/redoing a mix of reviews and other changes.
Fixed custom scheduling not working.

Other changes:

Alpha 1

Build 10bfb95f / 2021-05-17.

There have been a lot of under-the-hood changes in this release, and there may be some rough edges at the moment.

Undo handling:

Most actions now support multiple undo steps. You can change a card template, delete some notes, bury a card, then undo each of those steps if you wish.
Actions that support multiple undo steps will now save the changes immediately, meaning that if Anki crashes, the changes you made in the last few minutes will no longer be lost.
Actions that don't support the new undo handling (eg, Check Database), will clear the undo history.
Add-ons will clear the undo history if they modify the database directly, or use routines that don't support undoing. There are some new routines available to add-ons to make operations undoable, but add-ons may need to be updated to use them.

Scheduling changes:

An experimental new scheduler.
The deck list now shows the learning count separately.
On new collections, the v2 scheduler is now the default.

Browser changes, thanks to Rumo:

The sidebar now has two modes. The default allows clicking on items to search for them. The other mode allows you to select multiple items at once, so you can drag & drop or delete multiple items.
The browse screen can now be toggled between showing cards, and showing notes.
When showing notes, some columns will show an aggregate over all the cards of a note.
Added an introduced:x search to locate cards first studied in the last x days.
Column rendering has been moved into the backend, and will be faster than before (but is still limited by the speed of the graphics toolkit).
A fair bit of the browser code has been changed, and some add-ons like the "Advanced Browser" add-on will need to be updated to support the new approach.

Editor changes, thanks to Henrik:

The editing toolbar has been reimplemented in a way that will allow easier improvements in the future.
The toolbar's icons and style have been updated.
The editor now provides bullet and numbered list buttons.
The editor now provides buttons to control text alignment and indent.
Sticky fields can now be toggled on/off from the editing screen.
Editor shortcuts are handled differently, and the current approach does not work well on non-QWERTY keymaps. This will likely change before a stable release.
A new API is available for add-ons, but this has not been finalized yet.

State handling:

When you make changes, the user interface should update more consistently now. Adding a new tag to a note will update the sidebar in the Browse screen for example, and when you review a card that is shown there, the columns will update.
The Browse screen no longer refreshes a search automatically. When you make a change, the column text may update, but the number of rows will not change. Deleted cards show "(deleted)" until you search again.
The main window no longer shows a "waiting for editing to finish" screen. When you make changes such as editing a note, the main window will dim, and will automatically refresh when you return to it.

The deck options screen has been reimplemented:

(Re)learning steps are now shown with units, eg 10m or 4d.
Deck options are now shown on one scrollable page.
Extra help is available for most options.
It is easy to see at a glance which options have been changed from the default, and individual options can be reverted to the default setting.
Warnings will be shown for some common issues (eg, review limit too low compared to new cards).
Some of the more advanced options have been moved to a separate "Advanced" section.
The old options can be accessed with a Shift+click, since it will take a while for add-ons to be updated to support the new screen.
The deck description is now accessible via a button in the overview screen, instead of via the deck options.

Other changes:

Numerous behind-the-scenes improvements from Henrik and Rumo.
The Find&Replace option in the Browse screen can now be used on tags as well.
You can now choose which add-ons you want to update (thanks to BlueGreenMagick).
Fix text with single quote not being escaped in export (thanks to Ryan).
Other fixes and improvements thanks to Abdo, Glutanimate, Arthur and Shaun.
The Card Info screen ignores manual rescheduling when calculating the average time.
Performance improvements and other miscellaneous fixes.

Beta 4

Build 46e9720e / 2021-02-21.

Scheduler updates:

The V1->V2 upgrade process no longer resets cards that are in learning, or removes cards from filtered decks.
Users on the old scheduler will now see a message at the top of the deck list prompting them to update to the Anki 2.1 scheduler.
New users will see the message too. Enabling it by default would be a smoother experience, but that needs to wait until AnkiDroid 2.15 is released as stable, with support for the newer timezone handling.
There is no option to downgrade to the V1 scheduler anymore, though you can still do so by downgrading to an older Anki version first.

Sidebar changes:

- Ctrl/Alt/Shift options to add/modify the search now require a right click instead of a left click, to avoid conflicts with multiple selection.
- Move "Current Deck" to Decks
- Click on Decks to show whole collection.
- Click on Flags to show any flag.
- Click on Tags to show all non-empty tags.
- Added "Untagged" under Tags.

Fix compatibility with fastbar add-on.

Changes in 2.1.34beta2

Build 8af8f565 / 2020-09-22.

Fix a bug in Anki 2.1.28+ where a newly created deck config would default to an ease of 130%. When updating, Anki will automatically change any deck configs with an ease of 130% back to 250%, and change any cards using those deck configs with a low ease back to an ease of 250%. If you have deliberately set an initial ease of 130%, please change it to 131% or greater prior to upgrading, so that Anki leaves your settings alone. Users who updated from an older Anki version and did not add new deck configurations should not be affected. Thanks to Aleksa for discovering the issue.
Roll back most of the non-bugfix scheduling changes from the previous beta, so that this can be released as stable after a couple of days of testing.

Changes in 2.1.34beta1

- Startup and shutdown (the first startup will be slow as your collection is updated).
- The Browse screen.
- The deck list.
- The note types screen.
- The card templates screen.
- The database check.
Card generation changes:
- Card generation now supports negated conditionals, and a mix of required and optional fields.
- When adding/importing, if a normal note doesn't generate any cards, Anki will now add a blank card 1 instead of refusing to add the note.
- Please bear in mind that if you take advantage of these features, older Anki clients may report the cards are blank, or try to clean them up when you use the Empty Cards feature.
- Cloze numbers over 499 are no longer supported.
Card template screen:
- Changes are now accumulated, and can be saved or discarded when you close the screen.
- The front, back, and styling are no longer shown at the same time. You can switch between them with ctrl+1/2/3 or cmd+1/2/3.
- Added a search bar to search for text in the template or styling.
- Added a dropdown to change the previewed cloze number.
- Added a checkbox to toggle the filling of empty fields for preview.
- You can now delete a card template even if some notes are only using that template - they will be given a blank card 1 instead.
Scheduling:
- The deck list no longer caps counts to 1000.
- The overview and study screen no longer caps counts to 1000.
- The deck list will no longer show a parent count higher than the limit set on the parent.

- Notes with missing note types are now recovered instead of being deleted.
- Notes with missing cards are now recovered instead of being deleted.

If you are studying rare CJK characters and wish to prevent them from being converted into modern equivalents, the following in the debug console will stop Anki from normalizing note text.
```
mw.col.conf["normalize_note_text"] = False
```

Other changes:

Fields screen now accumulates changes, which can be saved or discarded when you close the screen.
Updated a few screens to show progress bars instead of hanging the UI.

Changes in 2.1.24beta9

  will match "dog" and "doggy", but not "underdog".
- w:*dog
  will match "dog" and "underdog", but not "doggy".

Changes in 2.1.24beta6

Build 394f7c63.

This beta changes the macOS dark mode handling of the standard build:

Anki now solely relies on the night mode setting in the preferences to decide whether to show in light or dark mode. Some users wanted to run Anki in light mode while keeping the rest of their system dark, and there were various display problems when dark mode was changed after Anki started that couldn't be easily worked around.
Users who only use dark mode, and preferred the native look of widgets in dark mode, can achieve the previous appearance by running the following command in the terminal:
```
defaults write net.ankiweb.dtop NSRequiresAquaSystemAppearance -bool no
```
And the following in the debug console:
```
mw.pm.meta["dark_mode_widgets"] = True
```
This is hidden behind a debug console command because it requires the user ensure their system is always set to the same light/dark mode as Anki.

Other changes:

The macOS standard build is built with a newer SDK. If you notice any regressions, please let me know.
Fixed Anki closing after a full sync on collection load.
Fixed an error being shown when replaying audio.
Fixed filtered decks displaying an error in older Anki versions after downgrading.

Changes in 2.1.24beta3

Build d3964603.

Updated the way cards and deck options are loaded and saved. Most add-ons should not be affected, but a few will need minor tweaks. If you run into any issues and can reproduce them when add-ons are disabled, please let me know.

Fixed the wrong language shown in the preferences screen for some languages.

Changes in 2.1.24beta1

Build 9dda5cf6.

2.1.24 focuses on changes to the database layer and searching code.

Searching:

You can now use re:something to search via regular expression, eg:
- re:\bdog\b will search for the word 'dog'. It has a word boundary character (\b) at the start and end, so it will match 'a dog', but not 'a doggy'.
- front:re:t+1 would match "t1", "tt1" and so on in the Front field
- When searching by regex, unicode case folding is used, so searching for re:über will show a card that has "Über" on it.
nc:something (short for "no combining") can be used to search while ignoring accents, eg nc:uber will match both "über" and "Über". This behaves the same way as the "Ignore Accents" add-on, but is about 16x faster.
You can now sort on the deck, card template, note type and tags columns.
You can now use wildcards when limiting the search to a field, eg field*:something.
You can now use wildcards when searching for a card template or note type by name.
rated:x searches are now capped to a year instead of a month.
You can now escaped double-quotes in a search - eg "foo\"bar"
Single-quote searches are no longer supported.
A version of Advanced Browser that works with this beta has been made available here. Not everything has been tested, and sorting on some fields will not currently work properly.
Because the searching code has been rewritten, add-ons that modify the search code will need to be updated to support 2.1.24. Unfortunately it is no longer possible to override the Finder class - add-ons will need to use the new hooks in the browser screen to either rewrite the search text, or perform their own lookups instead.

Database changes (mainly of interest to add-on developers):

Anki now uses Rust's sqlite libraries instead of Python's.
The 'db' object on the collection retains most of the same API as before, minimizing the amount of immediate code changes that are required.
Some less-used features like named sqlite bindings ("where column = :foo") and custom sql functions are no longer supported.
The old database code remains in db.py, and add-ons can continue to use it for accessing their own databases.
The database is now behind a mutex, and can be safely accessed from a background thread.
Various screens like the database check have been updated to run on a background thread, so they no longer lock up the UI while they're running.
The database progress handler has been removed. Anki previous had sqlite call back into Python periodically during long-running DB operations so it could drain the UI queue, but this would vary in choppyness depending on the type of DB operation being performed, and it was the cause of some crashes in the past. Add-ons that perform long-running operations should instead use mw.taskman.run_in_background() or their own threading solution moving forward.

Other changes:

Anki will now wait for a media sync to complete or be aborted before closing the collection.
Fixed progress dialogs failing to appear in a timely manner.
Allow the type answer arrow to be styled (thanks to Evandro).
More hooks (thanks to Arthur).

A lot has changed in this beta, so some issues may have slipped through the cracks. If you run into any problems, please let me know.

Changes in 2.1.22beta2

Changes in 2.1.21beta1

Build 683b7983.

Media syncing improvements:

Media syncing now happens in the background, so you can continue using Anki while the media sync completes.
Aside from syncing at open and close, Anki will sync any media changes every 15-20 minutes.
You can click on the sync button while the spinner is active to monitor progress.
Long filenames and problematic characters should be handled smoothly now, instead of causing syncing errors.
Anki should no longer sometimes forget to download files when a media sync fails due to network errors.
When media files are added within Anki, Anki now marks them in the database immediately, which can make things faster for people with slower disks if they are not modifying the media folder externally.

Media check improvements:

The Check Media function now shows progress, and can be interrupted.
There is now a separate button to generate missing LaTeX.
If LaTeX fails to build, the problem card will be revealed in the browse screen.
When Anki finds files that are too long or would cause errors on some operating systems, it will automatically rename them and update your notes to point to the new filename.

Both media sync and the media check now place deleted files in a media.trash folder inside your profile, instead of placing the files in the system trash. Any files that have been sitting in that folder for a week or more will be deleted permanently when you next run a media check.

Other changes:

Updates to the translation infrastructure:

The upcoming 2.1.21 beta is introducing a new way to translate strings, and in order to support it, the translations website will be moving again.

The new system uses Fluent (https://projectfluent.org/) instead of gettext. This has a number of advantages:

Separate identifiers are used for each string instead the English text, which means the English text can be improved without breaking existing translations in other languages.
It is easier to add comments to the translation files to make things clearer for translators.
Plural support is more flexible, and translators can add different plural forms even if the original English text doesn't use separate single/plural forms.
Translations can be more easily split up into multiple files.
Only a small number of strings are currently using Fluent, and most of the text in Anki is still using gettext. The plan is to gradually move more strings over to Fluent over time.

Because Crowdin does not support Fluent, I've set up a separate translations site using Mozilla Pontoon. Both the new Fluent strings and the old gettext strings are available. You can view it in read-only mode by visiting https://i18n.ankiweb.net

Changes in 2.1.20beta3

Build 95b497cc.

You can now use {{tts en_US:Field}} on your card templates to use the text to speech support built into Windows and macOS, changing the language code as necessary.
You can specify the voices you'd prefer - the first available one will be used. Eg. {{tts ja_JP voices=Apple_Otoya,Microsoft_Haruka:Field}}. The voices you specify must match the language.
In addition to the built in TTS, there is an example add-on that uses gTTS available here: https://ankiweb.net/shared/info/391644525
To see all available voices, use the following in the debug console:

for p in aqt.sound.av_player.players:
  if v := getattr(p, 'get_available_voices', None): pp(v())

Audio buttons are now shown on the card, and can be turned off in the preferences. They will show for both regular audio and text to speech.
Added shortcut keys in the review screen to pause and jump forward/backward 5 seconds.
Anki now starts a new copy of mplayer for each audio file on Windows, which avoids the need to create temporary files. If you notice any problems related to this, please let me know.
Add-ons that modified the audio code may break with this update.
For add-on authors, some more examples using the new hook system are available on the following page, including ported versions of the clickable tags and additional card fields add-ons: https://github.com/ankitects/anki-addons/tree/master/demos

Changes in 2.1.20beta2

Build c9a46268.

Anki will now check for add-on updates once a day.
Disabled add-ons are now included in the check as well.
If a user attempts to install an add-on that doesn't support the version they're on, Anki will now prevent them from doing so.
The 'max supported version' that add-on authors can specify in AnkiWeb is now used to prevent users from downloading add-ons that won't work on their Anki version, and to disable add-ons when they update to a new version.
Fix incorrect delay being logged when Hard is used on the first learning step in the V2 scheduler.
The editor no longer modifies percent-escaped text outside of image tags.
Fix an extra linebreak being left in a field when an image is attached to an empty field.

Changes in 2.1.20beta1

Build fa564772.

Changes to the way cards are rendered that will break some add-ons:

The card template rendering process in Anki 2.1.20 has changed significantly under the hood, and most of the code that was in the anki/templates folder has gone away. Add-ons that were relying on hooks to modify the card rendering should continue to function, but add-ons that were using or monkey patching methods in the templates module will break, as those methods no longer exist.

I have looked through the add-ons on AnkiWeb that modify the card template, and believe most of them should be able to accomplish what they were doing before by using the new card_did_render and/or field_filter hooks. Examples of how each of them can be used are available here:

https://github.com/ankitects/anki-addons/blob/master/demos/

For add-ons that were using the furigana/hint field modifiers, they are available for copying in the template_legacy.py file.

If the hooks are insufficient for what your add-on is doing, please let me know within the next few weeks. If you're an end user and an add-on you use has broken, please let the add-on author know of this post.

In terms of user-visible changes:

The limit of 100 replacements on a template has been dropped.
The new approach allow add-ons to add fields without 'unknown field' messages appearing on mobile devices (once they've been updated)
Fields with a ':' character are no longer allowed. If you have a ':' in your fields, you can open and close the Cards screen to automatically remove the colon.
Templates that reference a field that doesn't exist will now only show an error, instead of partially rendering.
{{field}} references are ignored inside fields, so there is no risk of LaTeX/MathJax being interpreted as a field reference.
The <% %> alternate syntax is deprecated, as it is no longer necessary due to the above change.
Clearer errors when the user forgets to close a {{field}} reference, or mismatches open and close conditionals.

A new hook system for add-ons:

Anki 2.1.20 introduces a new hook system that allows for better code completion and type checking than the old system. For a short explanation and link to some sample add-ons, please see https://apps.ankiweb.net/docs/addons.html#new-hooks

Add-ons using the old hooks should continue to work, as the new hooks will automatically call the old hooks in most cases, and a few runHook/runFilter calls have been left in the codebase in the places where the new hooks differ significantly from the old ones.

There are a bunch of hooks that previously were called with no arguments, such as when a new deck is created. The new hooks will tend to pass the newly created item into the callback, but will not do so for the legacy hooks, to avoid breaking old code.

If anyone has feedback on the naming or the arguments of the new hooks, please let me know during the beta testing period, so they can be changed prior to add-on authors relying on them.

To go along with these changes, the policy on adding new hooks has also changed. In the past, Anki's add-on documentation suggested hooks were best left for code paths that multiple add-ons wanted to extend, but this resulted in an over-reliance on monkey patching, and has made things fragile. The add-on documentation has been updated to encourage add-on authors to submit pull requests for any hooks they need, and the hope is that the bulk of add-ons can move away from monkey patching in the future.
