Changes in Anki 2.1
At a glance
Anki 2.1 uses the same scheduling, syncing and file format as Anki 2.0.x, so you can upgrade and downgrade at will.
It’s built with recent support libraries (Python 3.6, Qt 5.9/5.12), bringing fixes for crashes, better handling of high resolution displays, non-Latin text, and the latest web standards.
It requires a modern system - Windows 7+, OSX 10.10+, or a Linux distro from around 2014+.
Add-ons will need to be updated to work with 2.1.
Add-ons need to be updated to work with Anki 2.1. Some add-ons have already been updated; others have not been ported yet.
When you install 2.1, it will create a separate folder for add-ons, and not import any existing ones you have installed.
If you’re an add-on author, you can read more about the required changes on https://apps.ankiweb.net/docs/addons.html
Anki 2.1 brings numerous bugfixes, and some quality of life improvements, such as:
Built in MathJax support
A "restore backup" option in the profiles screen
SVG rendering support for LaTeX
Improved add-on configuration, management and updating
Night mode for reviewing
Improved pasting, with less unnecessary formatting included, and better handling of media links. You can hold the shift key when pasting to allow more formatting to be included.
The Browse screen has been simplified:
Various shortcuts that were previously in the sidebar are now available via the Filter button. If you find yourself frequently accessing certain items, you can save the search to have them appear in the side bar.
The top bar with common shortcuts has been removed. You can access all actions quickly by right clicking or ctrl+clicking in the card list instead, and there is an add-on available for adding back the top bar if you still prefer it.
A full list of changes made during the alpha and beta period are documented here.
Anki 2.1 contains an optional, experimental scheduler. The experimental scheduler is not compatible with older Anki versions.
