1) We’re still doing Thunderbird builds manually, as we’ve not had a chance to test the Build Automation used in FF releases. It *should* work, but needs to be tested properly before we switch to using automation in production for Thunderbird. Producing Thunderbird manually explains some of the delay in producing updates above – there was a weekend in there! Now that Rick has joined MailCo, he’s starting to get up to speed, and help out. We’ll still be doing TB184.108.40.206 manually, but hope to do TB220.127.116.11 using automation. Watch this space!
2) For better or worse, we are putting all our blow-by-blow scribbles public, so the curious can read about it, warts and all, here.
3) As usual, we waited until morning to start pushing to mirrors. This was done so mirror absorption completed as QA were arriving in the office to start testing update channels. We did this because we wanted to reduce the time files were on the mirrors untested; in the past, overly excited people have post the locations of the files as “released” on public forums, even though they are not finished the last of the sanity checks. Coordinating the mirror push like this reduced that likelihood just a bit. I’m counting that wait time as “Build time” even though that might be a little unfair to the Build team.
4) Mirror absorption took 4 hours to reach good values. A little longer then usual, unclear exactly why.
