We're finally back with a new release! Most features were already ready around a month ago, but the release was held back by some complicated dependency migrations and resolving some Linux compatibility issues. This is all fixed now, enjoy!

Note: You might have to set your language again from the settings, it is now saved in a more robust way that should work more reliably, especially on Linux.

## New features
* Added option to set dark/light mode based on system preference
* Added preference in settings to use relative due date countdown as default for new due dates
* Allow marking the due date of cards as completed
* Sidebar pins now support a single letter/character or an emoji as their icon
* Add Turkish translation (@Taiizor)

## Bugfixes and other changes
* Fixed Linux issues like `EGL_BAD_PARAMETER`, app should start on different configurations more reliably now
* Fixed a bug where moving cards while using search did not move the correct card
* Fixed a bug where pressing entire sometimes did not select an already existing tag
* Deleting a board now correctly removes it from the sidebar if it's pinned
* Disabling animations also disables tooltip animations (
