anki

If updating from 2.1.57 or earlier, please see the important note in the 2.1.58 change notes.

• Add button to tag notes with missing media (thanks to Rumo).
• Fix slow editor startup for users with lots of fields (thanks to Hikaru).
• Fix a regression in 2.1.58 that broke TTS add-ons (thanks to Rumo).
• Fix HTML editor hiding when shown by default (thanks to Fabricio).
• Fix some widgets not indicating they're disabled (thanks to Matthias).
• Fix deck options selector not updating the current entry sometimes (thanks to Fabricio).
• Fix type box losing focus when switching IMEs (thanks to Hikaru).
• Fix 'toggle bury' not updating for automatically-buried cards.
• Improvements to lifecycle handling for add-ons accessing Svelte components (thanks to Matthias).

This release has been yanked due to a packaging error. Please see 2.1.60 instead.

This release fixes an issue in 2.1.57 that caused cards and deck presets
to be reset to the default ease, if you exported a .colpkg with compatibility
with older clients enabled, or used the downgrade and quit option, then opened
the collection again. For the former issue, this occurred to the collection you
were exporting from, and not just the .colpkg file. If you were affected by this,
running the following in the debug console after updating should restore your
cards to the ease they were at when you last reviewed them, if they were not
reviewed after the problem occurred. Please make a backup before proceeding.

updated = 0
for cid, old, new in mw.col.db.all("select id, factor, (select factor from revlog where cid=cards.id order by id desc limit 1) as factor2 from cards where type=2"):
  if new and old != new:
    card = mw.col.get_card(cid)
    card.factor = new
    mw.col.update_card(card)
    updated += 1
print("updated", updated)

It will print the number of updated cards.

If updating from Anki 2.1.49 or below, please see the 2.1.50 change notes first.

Editor Improvements

• Rework image resizing (thanks to Henrik). Images expand to the editor width by default now,
  and images that are resized for the editor will remain that way if you switch fields, or
  navigate to a different note and back.

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.
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 first.

• Improve editor startup time, especially with many fields (thanks to Henrik).

Fixes:

• Fixed compatibility with older macOS versions.
• Fixed an issue that was breaking some add-ons when running on Windows without using anki-console.bat
• Anki now closes the Browse screen before full sync or colpkg import/export, so it doesn't show errors.
• Automatically re-enable disabled add-ons when user explicitly reinstalls them, and improve conflict handling (thanks to Aristotelis).
• Fixed an issue with the search history when clicking on items in the sidebar (thanks to Rumo).
• Fixed card layout screen opening too wide if card template name was long (thanks to Sam).
• Fixed compatibility with 'card info during review' and similar add-ons.

Platform-Specific Changes

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:

• 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
  life.
• The Qt6 x86 build requires macOS 10.14.4
• The Qt5 x86 build requires macOS 10.13.4.

Linux:

• 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.

Qt6

Please see the notes for your platform:

• Windows
• Mac
• Linux

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
  page for more
  info.
• 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).

  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$.

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

• Fixed cards not being automatically unburied when v3 scheduler enabled.

• The card templates screen no longer defaults to filling empty fields when
  opened from the Add screen (thanks to BlueGreenMagick).
• Miscellaneous other fixes.

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:

• The "timebox finished" message is now shown on card answer, instead of after
  revealing the next card. This should also address an issue where the message
  popped up outside of review.
• Added shortcut for Forget in the Browse screen.
• Fixed an error being shown when there was no current deck.
• Fixed incorrect quoting in duplicate search (thanks to Abdo).
• Fixed deck options inverting the "replay question when showing answer" option.
• Fixed an issue with ampersands in the Add Cards history button (thanks to
  Arthur).
• Fixed handling of audio/video tags (thanks to Hikaru).
• Fixed errors playing audio when computer was slow to respond (thanks to Kelciour).
• Fixed preferences screen not updating undo menu, and causing an error when
  subsequently reviewing a card in the v3 scheduler.
• Fixed case changes being ignored in tag rename.
• Fixed error shown when DB check run on corrupt collection.
• Fixed deck options prompt showing the default deck, instead of the correct one.
• Fixed reposition command ignoring suspended cards.
• Fixed answer button highlight on Windows (thanks to Henrik).
• Fixed calendar graph day labels showing incorrectly in some timezones.
• Improved validation of add-on package names (thanks to BlueGreenMagick for the
  report and initial fix).

For add-on developers:

• The Svelte components Anki exports should now work correctly in add-ons,
  provided they exclude Svelte when bundling.
• WithShortcut is now also available.

• Fix duplicate text when pasting with Ctrl+Shift+V (thanks to Henrik).
• Remember last colors in editing window (thanks to Henrik).
• Show flag and mark icons in preview window (thanks to Hikaru).
• Center first match when searching in sidebar (thanks to Abdo).
• Added F9/Shift+F9 shortcuts for sticky fields, and increase opacity (thanks to
  Henrik).
• Fixed starting ease specified in deck options not being used by v3 scheduler.
• Fixed learning cutoff not updating during review, and some learning cards
  remaining at the end of review in the v3 scheduler.
• Fixed Change Notetype not mapping fields correctly when count differed.
• The congrats screen now updates periodically again.
• Fixed Redo menu item showing Undo action name.
• Fixed notetype selection in the import screen.
• Fixed error in overview/congrats screen when there is no current deck.

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.
• Most undoable actions can now be redone, so you can undo an accidental undo.
• 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:

• A new scheduler is available, with a number of improvements. Please see the
  2021 scheduler page for
  more information.
• The deck list now shows the learning count separately.
• On new collections, the v2 scheduler is now the default.
• Set due date uses the deck's configured starting ease (thanks to cyphar).

Browser changes, mostly 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.
• New tag icons and associated backend work (thanks to Henrik).
• Added an option in the Preferences screen to customize the starting
  search text (eg, to start with "deck:current").
• More reliably scroll to the current card.
• When opening the Browse screen with an active study card, the whole
  deck is now shown.
• Added 3 new flag colours.
• Flags can now be renamed in the sidebar.
• Horizontal scrolling in the browse screen is less jumpy.
• Sidebar items can be dragged onto the Saved Searches area to add them as a favourite.

Editor changes, mostly thanks to Henrik:

• A new editor toolbar implementation, with improved icons and handling.
• 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.
• A new API is available for add-ons, and the existing API should continue
  to work.
• The HTML editor is now shown inline, and supports syntax highlighting,
  and showing opening/closing tags.
• Warn user when they attempt to use cloze markers inappropriately
  (thanks to Rumo).

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. A new API is available,
  thanks to Henrik.
• The deck description is now accessible via a button in the overview screen,
  instead of via the deck options.

Other features:

• An updated Change Notetype implementation, that can match fields by name, and
  allows you to map a source field to multiple destination fields in order to
  clone a field.
• Pre-load images on answer side (thanks to Hikaru).
• The [...] in cloze deletions is now read as "blank" by TTS (thanks to Rumo).
• The Find&Replace option in the Browse screen can now be used on tags as well.
• Added a Card Info option to the review screen.
• When opening deck option from the study screen, you'll now be asked which deck
  you want if the card is in a subdeck.
• You can now choose which add-ons you want to update (thanks to BlueGreenMagick).
• Support system SSL certs on Linux.
• Extra checks are now done when updating a card template, such as detecting when
  a cloze notetype is missing a cloze directive, or two templates have identical question sides (thanks to Rumo).
• Support Ctrl+Numpad Enter to add cards.
• Added night mode styling to 'type in the answer' box, and improve legibility
  of comparison.
• Sidebar search now scrolls to first match (thanks to Abdo & Rumo).
• F3/F4 in card layout screen go to next/previous template (thanks to Evandro).

Fixes:

• Custom study now limits the tag selection to 100 tags or fewer, to prevent errors caused by exceeding database limits.
• Fixed an issue compiling on recent Python 3.9 installs.
• Fixed audio getting stuck when pausing near end (thanks to kelciour).
• Fixed building on linux-arm64 (thanks to qubist-pixel-ux).

• Fixed various links to the manual (thanks to cherryblossom000).
• Fixed red duplicate background being included in copy+paste (thanks to Hikaru).
• Fixed flags not being excluded on export (thanks to Alex).
• Force x11 mode when the packaged build is run on a system that tells Qt to use
  Wayland, as Wayland is not currently supported by the packaged build.
• Numerous behind-the-scenes improvements from Henrik and Rumo.
• Other fixes and improvements, thanks to Abdo, Glutanimate, Arthur, Shaun,
  hkr and others.
• Strip invalid unicode from filenames in media check.

Browser improvements:

• Tags now show in a tree (thanks to Abdo).
• Added a search bar to the sidebar (thanks to Abdo).
• New context menu actions to rename or remove tags and their children, rename
  decks, manage notetypes, and rename/remove saved searches (thanks to Abdo
  and BlueGreenMagick).
• The preview button in the browse screen has moved into the editing area (thanks to Henrik).
• With the improved sidebar, a number of options have been removed from the Filter button.
• The remaining items in the Filter button have been moved into the sidebar, and
  the Filter button removed.

  not only the start.
• Invalid field content can no longer spill out into the editing area (thanks to Henrik).

Search improvements:

• Searches are now rewritten into a canonical format (eg one two becomes
  "one" AND "two") (thanks to Rumo).
• Search error messages are now much more specific (thanks to Rumo).
• is:learn, is:due and prop:due now handle more cases, such as suspended cards
  (thanks to Henrik).
• Added prop:pos search to search for new card position (thanks to Abdo).
• Added a shortcut to replace part of a search with a different search
  (eg changing the selected deck) (thanks to Rumo).

• The intervals and ease graphs now covers more cases, such as suspended cards
  (thanks to Henrik).
• Place less emphasis on outliers in the Calendar graph (thanks to Henrik).
• Ignore manually scheduled cards in hour graph.

Scheduler improvements:

• The V2 scheduler no longer applies parent review limits to child decks.
  Previously the limits were inconsistently applied, which could lead to the
  deck list not reflecting the actual number of cards you'd receive when you
  clicked on a deck. AnkiMobile and AnkiWeb have been updated to match this
  behaviour, and AnkiDroid will also be updated soon. Using 2.1.41 in
  conjunction with older clients will not cause any problems when syncing, but
  you may find the deck list/review counts do not match.
• 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.
• 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.

Reworked the Reschedule tool:

• Split into separate "Forget" and "Set Due Date" actions
• "Set Due Date" defaults to not adjusting the card interval.
• Changed the "Delete Tags" shortcut; Ctrl+Shift+D now changes the due date.
• Added the action to the review screen as well.
• Input now remembered.

Other changes:

• A basic sync server is now built into Anki. It does not yet support
  media. Docs are in the docs/ folder of the source tree.
• The title bar on Macs will now turn dark when night mode is activated.
• Deck descriptions of the congratulations screen can be enabled by turning markdown
  on in the deck options, but only 2.1.41+ will be able to render the markdown.
• Add opus to media list in editor.
• Edit/More buttons auto-hide when window is small (thanks to Henrik).
• Support Alt+number to switch between clozes in the card layout screen (thanks to Abdo).
• Use monospace font in HTML editor.
• Improve error message when trying to nest under a filtered deck (thanks to Rumo).
• Reposition dialog's "shift cards" option now defaults to off.
• Other fixes and improvements thanks to Henrik, Rumo, Abdo, Arthur, Maksim, Guillem,
  stayingpeachy, Daniel, khonkhortisan and Kerrick.
