CHANGELOG
IMPORTANT: While likely compatible with earlier versions, add-on versions v1.0.0 and up have only been extensively tested with Anki 2.1.49+. The AnkiWeb upload is therefore limited to Anki 2.1.49+ for the time being (but might be expanded to earlier releases in the future).
If you are on an earlier Anki release there is no need to worry: Copying the AnkiWeb add-on code into the app will automatically download a compatible version of the add-on for you. However, please be aware that it will not include the latest changes below.
Version 1.0.1 – 2022-06-30
