User:NThomas:Process changes
bug 908134 is set to change the release process around the final beta and release builds. The aim is to take the exact bits release users will get and give them to beta users, to catch the Radeon crash problem early.
Current process
Here's the current state of process, sketch-style, for the 27.0 cycle. D-Day is relative to when we release the build to the world. All activities are in column for the source repository used to create that build.
| D-Day | This cycle | mozilla-beta | mozilla-release |
| -8 days | Mon 27 Jan | Last changes for 27.0 land here | |
| Build last beta (27.0b10) | |||
| QA tests (functional, updates on releasetest) | |||
| Merge code from mozilla-beta to mozilla-release | |||
| Build 27.0 build1 | |||
| -7 days | Tue 28 Jan | QA sign off on b10 testing | |
| Enable updates on beta channel, QA verify updates | |||
| QA tests (functional, updates on betatest) | |||
| -4 days ? | Friday ? | QA signoff | |
| -1 day | Monday 3 Feb | Final signoff checks | |
| Push to mirrors | |||
| QA check updates on releasetest | |||
| This is it | Tue 4 Feb | Push to release channel, QA verifies |
New process
Here's how it would look after we change things. Removals are marked with a red background, additions with a green one.
In words - we don't create a beta 10 build, instead we offer the release build on the beta channel as soon as we complete the normal beta-level of testing. Then continue with regular release testing and ship as before.

What about respins ?
Suppose we find some bugs in 27.0 build1, what then ? I'm assuming we will want the fix on both beta and release channels. The code changes need to land in mozilla-release and we will spin a 27.0 build2. The release automation will run the same as build1 from the point of view of updates - we will be ready to push build2 to the beta channel if we think there is value. There may not be, eg too close to release to get crash feedback and 28.0b1 coming soon, but we'll have the option.
Repeat as required up to buildN.
