(I'm afraid you'll get a lot of spam^W mails from me these days...sorry for those of you who read mailing lists....but some others don't, so I prefer sending you important informations directly)
The string freeze will officially last until October 7th 00:00UTC. So this is the deadline for your translation updates.
Because of the delays induced by the l10n-sync script, I highly suggest you don't wait the very last minutes for your updates. So, consider that the deadline is 10/7 16:00UTC.
I cross my fingers for not upstream changes (it looks like one or two happened this night *after* the freeze....you can be sure that I will protest in your name)
