Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (lmandel)

Next Merge: February 23, 2015		Next Release: February 24, 2015
Trains
Central: 38	Aurora: 37	Beta: 36	Release: 35

• Today is release day! Congratulations on releasing Firefox 35 and Firefox ESR 31.4!
• 36 Beta1 ships Thursday
  • MSE is enabled in beta1. Please test YouTube playback on Windows and file bugs.
• 37 Aurora updates are scheduled to be re-enabled on Friday
• 38 Nightly will be the next ESR. Get your refactorings or other major changes in while 38 is on m-c.

A note on branching:

• FXOS v2.2 update : Please note that has diverged from mainline gecko and is on its own b2g37 branch. mozilla-aurora (gecko 37) will continuously be merged to mozilla-b2g37_v2_2 . So, if you have a gecko bug that you are fixing on aurora and impacts b2g as well, you do not have to worry about requesting approval twice as the sheriff’s will auto-merge it for you.
