Hi, everyone,

I would like to share with you the current engineering status of Firefox OS
2.2. On February 23rd, we reached the feature landing milestone which means
the feature implementation of Firefox OS 2.2 was done, and we are
stabilizing 2.2 now.

Currently, we are still improving the quality of 2.2. These are the metrics
for feature complete milestone :

The testing results of Firefox OS 2.2 with Flame KK are:

1. Full test (4 weeks in March)

   - Bug list <http://mzl.la/18T1AMy>

2. Smoke-test

   - an OTA bug breaking smoke-test https://bugzil.la/1139331

3. MTBF

Thanks for all teams to devote all ourselves in this version and improve
whatever we can.

FxOS 2.2 will be based on Android 5.1 which came out recently, hence we
have to make changes to support. Here is the updated schedule:

   - *04/13 ~ 04/14: *QAs start to do testing before full run.
   - *04/15 ~ 04/28:* Android 5.1 full run testing.
   - *04/29:* feature complete milestone.

The code complete milestone may be moved from May 18th to June 8th which is
3 weeks later. We will try our best to retain original code complete
date(May 18th), but depending on the quality of builds and number of
blockers remaining for 2.2 and to accomodate bug fixes beyond the late
feature complete we may use the three weeks push for this milestone. Please
reach us if you have any further questions.

Thank you.
