[robe]

Came out July 1st.

Released on July 1st 2022. ​https://docs.weblate.org/no/weblate-4.13.1/changes.html

Fixed tracking suggestions in history.

Fixed parsing reverse proxy info from Cloudflare.

Make parse error lock a component from translating.

Fixed configuring intermediate file in the discovery add-on.

Fixed DeepL translations behvior with placeholders.

Fixed untranslating strings via API.

Added support for removing user from a group via API.

Fixed audit log for user invitation e-mails.

Main fix I was looking for is the " Make parse error lock a component from translating." which would have prevented the email storm we experienced with #2778
