Here is my status report for November 2022.
At the beginning of the month, I attended the Reproducible Build 2022 Summit in Venice . I discovered a lot of new stuff there, and hopefully, we might apply some to Tor Browser, too.
Then, for the rest of the month, I mostly worked on refinements to Tor Browser 12.0 series.
One of the most important features I have worked on is improving the experience with the multi-lingual builds. For example, I have implemented a notification to explain to the user why Tor Browser chose that language, with a button to go directly to the language preferences .
I have also fixed a few bugs introduced by the tor-launcher refactor .
I also managed to get yet another patch upstreamed to Firefox .
I had another important task, too: reviewing the profile files with our custom Firefox configuration . I removed some old settings, added new ones, and tried to add missing links to our bug tracker for the ones that we already had. I hope this will help us with future documentation and review work.
Finally, I helped to prepare some releases and to verify the reproducibility of the ones we released.
We should be very close to 12.0 becoming stable: we are very excited about it, and we would love to get any feedback. So, please, consider downloading  the fifth alpha of 12.0 (we are publishing it later today) and giving it a test ride .
Thank you very much,
