Strings are frozen now in the 2.3.x branch so that translations can be prepared for LyX 2.3.3. Please have these done by Sunday, 19 May. I'll plan to build the release shortly thereafter.
Apologies that it has taken so long to get 2.3.3 out. It's been a crazy semester. Riki PS Apologies for duplicate messages, too. I sent from the wrong account the first time.
