Firefox 40.0b9

• Intermittent compiler crash in win32 build
• Time out cleaning up in update verify
  • It's getting really hard to notice these in the wake of the permafailing ui update verify tests, ended up shipping before the rerun completed

Fennec 40.0b10

100% smooth.

Firefox 38.2.0esr

• Updates builder failed because bug 1188014 didn't land before the release started.
• Update verify failed because extra test channel esr rules were not removed

Firefox 40.0

• Lots of intermittent issues:
  • Download MARs from stage
  • Out of space on windows
  • Mac update verify
• Somewhat interconnected update issues:
  • Release channel updates builder failed because of fallout from partner-only 38.0.6 builds
  • This exposed dependency issues that we normally don't see, where beta channel update verify relies on some parts of the release channel updates builder.
  • Beta update verify probably would've failed anyways, due to 39.0 -> 40.0 partials not being specified properly. This was fixed with a manual tweak of the blob.

We should look into a couple of things here:

1. Look into whether empty update response are cached bug 1190779
2. Figure out how to cope better with multi-channel versions, such as 39.0 -> 40.0.

Build 2 is coming.
