2.1.38

• Use a new approach for recording audio. If you encounter any issues,

  releases (thanks to Ryan).

  order.

• The deck options screen now limits minimum ease to 131%.

For developers:

• Added a scripts/build command to build the redistributable wheels.

2.1.36

Notable changes:

• Alternate builds have been discontinued. If you are using a 32 bit system, or
  a macOS version older than 10.13, Anki 2.1.35 is the last release you will be able
  to update to.
• MathJax has been updated to version 3, thanks to Henrik. It should render faster
  than before. If you were customizing the MathJax configuration using Javascript,
  you will need to
  use a new method.
• A separate mpv process is now used to play videos on Windows, which should
  solve issues with playing getting stuck, thanks to Kelciour.
• The handling of wildcards and escape characters in search has been
  reworked
  to be more consistent, thanks to Rumo.
• Early startup messages are now translable, thanks to Abdo.
• When cards are rescheduled in the browse screen, a review entry log is now created.
• The main card area is now focused instead of the bottom area during review,
  which allows using the keyboard to scroll, thanks to Henrik.

Bugfixes:

• Fixed duplicate search when sort field is not first field (thanks to Abdo).
• Fixed error when switching to note type with fewer fields.
• Fixed invalid utf8 in notes when checking database.

• Fixed issues with "find duplicates" (thanks to Abdo)
• Fixed some issues with adding/renaming decks (thanks to Cecini).
• Other minor fixes.

For developers:

• Anki is now built using Bazel. This leads to more reliable builds, and reduces
  the number of dependencies you need to manually install. Please see docs/ for
  updated build instructions, and report any issues you encounter on the user
  forums.
• The minimum Python version has been updated to 3.8.
• The wheels available on PyPI support both Python 3.8 and 3.9.
• All translations have been migrated to Fluent.
• Normal and night mode theming now uses CSS variables, making it easier to override in add-ons.
• The congrats screen, burying/suspending, filtered deck building/emptying, browser sidebar, and card
  reposition/reset have been reworked. If you were modifying them in an add-on, your add-on
  may need updating. For the congratulations screen, see the new webview_did_inject_style_into_page
  hook

2.1.35

This is the last Anki version that supports 32 bit Windows machines, and macOS 10.12 and older. If you use either of those, please pick the -alternate version.

• Fix a bug in Anki 2.1.29+ that caused excessive memory and CPU usage
  on long-running operations that show a progress bar, such as importing.
• Roll back Mac and Windows builds to Qt 5.14 again,
  as there are still issues with 5.15.

2.1.34

• 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%. Users who updated from
  an older Anki version and did not add new deck configurations should not be
  affected. 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. Thanks to Aleksa for discovering the issue.
• Update the standard builds to the latest GUI toolkit version.
  Please report any improvements or regressions you notice.
