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.

• 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.
• Empty cards screen:

• Notes will not be deleted by default.
• Empty cards are grouped by note type.
• Empty cards can be clicked on to reveal them in the browse screen.
• Database check:

• Notes with the wrong field count are now recovered instead of being deleted.
• Notes with missing note types are now recovered instead of being deleted.
• Notes with missing cards are now recovered instead of being deleted.
• Unicode normalization:

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

Build 359b9f5c.

• You can use w:something to search on word boundaries, eg:
• w:dog
search for "dog" on a word boundary - will match "dog", but not "doggy" or "underdog".
• w:dog*
will match "dog" and "doggy", but not "underdog".
• w:*dog
will match "dog" and "underdog", but not "doggy".

### Changes in 2.1.24beta8

Build 683f664d.

• Fixed adding and removing deck option groups.

### Changes in 2.1.24beta7

Build ec6c0f86.

• Move the scheduling options in the preferences to a separate tab, so options fit on the screen even on devices with small screens.
• Fix pauses caused by a regression in the previous beta.

### 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.
• Fixed add-ons with multiple branches not updating properly.
• Change the way cloze deletions in RTL fields are handled, which should address some corner cases.
• Fix editor buttons not being highlighted (thanks to Simone).
• Improve invalid HTML/JS error messages (thanks to Evandro).
• Fixed a useless log file being created when exporting.
• Allow selecting add-on config help text (thanks to ijgnd).

### Changes in 2.1.24beta5

Build 0c5f22f4.

• New load/save handling for note types and decks. This should be transparent; if you notice any issues, please let me know.
• Avoid scrolling if the selected browser row is still visible after an operation.
• Handle renamed cloze fields when previewing (thanks to BlueGreenMagick).
• Fix a case where decks could be sorted incorrectly (thanks to Arthur).

• Allow dragging fields to change their position (thanks to BlueGreenMagick).
• Add socks support to media sync.
• Improvements to debug console (thanks to BlueGreenMagick).

• Fix interface getting stuck when a corrupt collection was encountered.

### Changes in 2.1.24beta4

Build 16ab351b.

• Updated tag handling:
• non-wildcard searches now do full unicode case folding (eg 'tag:masse' matches 'Maße').
• wildcard searches do simple unicode case folding.
• tag list in browse screen now uses unicode case folding.
• Fix 'is:due' search not combining with other searches properly.
• Fix searches for things like deck:current not reflecting current state.
• Fix duplicate searches.
• Be more tolerant of deck IDs stored in the wrong format by older Anki versions.
• Fix an error that could occur when performing an operation in the browse screen then immediately closing it.

• Improve the handling of deck deletions (thanks to Arthur).
• Avoid decimal place in steps lists where possible.
• Add a compatibility shim for named args to avoid breaking some add-ons.
• Updated config handling. While there should be no immediate breakages, if you're an add-on author and store lists or dicts in Anki's config, please see 676f4e74a.

### 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.

Other changes:

• Media syncs no longer take time to abort.
• Fixed media sync waiting forever when connection dropped.
• Fixed an issue where regular syncs could fail to end.
• Fixed current card sometimes not being centered when searching.
• Don't force a full sync when DB check finds cards with a high due number.

### Changes in 2.1.24beta2

Build b1a8107a.

Please see beta 1 for most of the changes.

• Fixed searches for "(something )" with a trailing space not working.
• 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

• More code improvements (thanks to Alan)
• More add-on hooks (thanks to Arthur and Glutanimate)

### 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.
