This looks like a big update, thanks!

I'm a volunteer contributor and I wanted to let you know that while PRs are still accepted for translation updates, it's now strongly recommended to use Crowdin to avoid conflicts.

If you'd like to get involved on Crowdin, it's easy to do and there's lots of info here:

Yes, Crowdin has been brought to my attention when I talked about the Bluesky in interlingua somewhere else. I already started to use it. Thank you very much!
