Echo display these messages since the last MW release:
However, these messages are not translated, and, for French, not marked as missing.
I've changed language on wiki and tested it to display English, Spanish, Breton and French. Only English is available. Something is missing concerning translations?
These messages are new. See T107823: Rewrite EchoNotificationFormatter and T116847: Write presentation models for notifications in Thanks.
notification-header-edit-thank is part of the Thanks extension. See https://translatewiki.net/w/i.php?title=Special:Translate&group=ext-thanks&language=fr&filter=!translated&action=translate
notification-header-mention and notification-header-mention-nosection are part of Echo. See https://translatewiki.net/w/i.php?title=Special:Translate&group=ext-echo&language=fr&filter=!translated&action=translate
There's many more coming in about 8 extensions. See T116834: Write presentation models for all notification types
Thanks a lot for this clarification @SBisson. Just to know if something is missing, this has not been announced, correct?
I haven't seen anything about it. How do we usually announce new messages that need translation?
I've sometimes seen major translations changes announced on TechNews. I've asked Johan about that.
I'm sending an email to translators-l, and this will be announced on TechNews as well.
Any reason to think this is different from the long-standing brokenness of WMF's deployment system, reported at T103879: l10n-update not updating Vector and extensions?
Not really.
They have been fixed.
Definitely not.

But https://fa.wikipedia.org/wiki/%D9%85%D8%AF%DB%8C%D8%A7%D9%88%DB%8C%DA%A9%DB%8C:Notification-header-mention is still in English.
