Good news - L10n nightly updates:
We now have l10n updates available on the 1.9.1 branch (builds that will become Thunderbird 3) as well as on trunk. Please tell your users, who regularly test Thunderbird about this.
The TB developers are still aiming for an RC1 code freeze on October 30, an RC1 l10n freeze on November 2 and the RC1 release on November 3.
However, at the time of writing there are still 35 blocker bugs open for TB3, which might not all make it in time. If that happens and the schedule slips a bit, I'll let you know immediately and you may get more time for tanslations and QA.
We also do not know yet, whether we need an RC2 or not. If it turns out that we do, I'll let you know and we will take additional opt-ins for that as well.
With all the QA that you are currently doing on your localized TB3 builds, please do not forget to update your opt-in changeset when you push changes to your 1.9.1 hg repo.
At the time of writing we still have 41 green locales (counting the two Japanese locales as one locale) on the dashboard.
From the remaining locales with less than 500 missing strings I've gotten assurances that they will update their locales soon. So we will shoot for 49 locales (incl. en-US) for the TB3 final release.
We still have only 26 locales, who have opted-in so far with only five days to go until the l10n freeze/cutoff date. So if you think you are ready, then please update your opt-in changeset or opt-in for Thunderbird 3.
Here are the locales that have opted-in so far:
