I'd especially like to see improvements in the Italian translation which was one of the first in Weblate beginnings, but hasn't received much love in past years.
Weblate 2.16: Call for translations
Do you have a project on one Weblate server and need to move it to another? Weblate 4.14 got your backup! This is the feature we are very proud to deliver in this release. It also welcomes new projects to Hosted Weblate as the backup and restore do not need to include the whole server anymore.
Many improvements in formats and Automatic Suggestions configuration in UI!
Nice and brief, that is 4.12; bringing TM management and checks improvements.
