Anki

Audio changes:

• Text to speech is now supported in card templates.
• 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.
• You can customize the size and colour.
• 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.
• Added an option in the preferences to not interrupt the currently playing audio when answering.
• Fix multiple spaces in filenames from getting truncated when pasting sound files.

Night mode:

• The night mode option in the preferences screen now turns the interface dark as well.
• On macOS, when the system is in dark mode, Anki will switch to night mode automatically.
• Invert LaTeX in night mode (thanks to zjosua).
• Some of the colours in areas like the graphs could be improved - pull requests with included screenshots of the changes would be appreciated.

Add-on changes:

• Anki will now check for add-on updates automatically once a day.
• Disabled add-ons are now included in the check as well.
• Add-on authors can specify the minimum and maximum Anki version they support, and add-ons will be automatically disabled when running on an unsupported Anki version.
• Add-on authors can now upload different add-on versions for different Anki versions, and Anki will download the correct one.
• A new hook system for add-ons - please see here.
• 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
