• Announcement
  • Please thank Alexandre Lissy for his work on getting build scripts for automating FOTA builds for both aries and flame
    • it's not within his realm, but because we do not have a b2g build engineer; he has unblocked QA and moved these parts forward.

TEAM UPDATES

(Alphabetical order)

Gaia Architecture Work

• Telemetry library

   -We are closing in on feature complete.  

   -Few more review items outstanding + 1 blocker with app startup time we are working on.

   -Contacts team is trying out the custom metrics.

• Web app bridge
• Service workers
• SMS app conversion
• Music app conversion

   - Working on performance optimizations and functional bug fixes. (see more below)

• Contacts app conversion

   - No new updates, working on blockers, we got ride of the performance regressions, but still we can see how contacts 2.2 in current mozilla central performs works than in gecko 2.2

   - Patch on the way, start using custom metrics to check how features are being used.

• Sync

   Landed, now bugfixing. Next week work week in Taipei to be sure 2.5 sync on tv will run smoothly.

Comms app

Talking this week: Updates:

Red Square

   Contract still being finaliized:  Contract has just been signed. Very little code has been written, but architectural discussions with outsourced engineers are ramping up

   We still don't have access to Red-Tai code

   Looking for engineers to take tech-lead role for gecko and the Caretaker service part of Red Square
