[tbb-dev] Release schedule for TBB based on FF52ESR?

Hi, I looked at the master ticket [0] for rebasing Tor Browser on FF52ESR, but couldn't find any sort of schedule. Is there somewhere else than Trac where I should look for such plans? Otherwise, do you have estimations for: * when to expect a development build? * when to expect the final release? This timing info is important for us at Tails, since the ESR migrations historically has required quite some work on our side. Cheers! [0] https://trac.torproject.org/projects/tor/ticket/21147
