Build Changes (gps)

(Build changes of which engineers should be aware.)

<Read Only>

  • WebIDL Windows clobber issues have hopefully been resolved!

Firefox OS Performance (mlee)

Firefox OS Productivity (doliver)

<Read Only>

1.3 status

  • Testing is well underway on our new 1.3 features. Find, fix, repeat.

1.4 status

  • We have reviewed the new targeted features for Clock, Calendar and E-mail
  • Team is scoping the work this week and we'll get started on development in the first half of January

Team updates

Lots of changes to report:

  • New team members: The UX group has moved around some assignments and we have four new team members in Taipei who will handle all of our UX needs: Mike Tsai, Neo Hsieh, Harly Hsu and Juwei Huang
  • Clock app: The Bocoup group have been working on this app for the 1.2 & 1.3 releases and Mike Pennisi at Bocoup is the current module owner. They are coming off the project at the end of January so we are beginning the process to transition the ownership of this app back into our team.
  • Notes/Notes+ app: Everything.me created these apps for the initial launch of FxOS and published them in the marketplace. They are no longer interested in maintaining the apps so we are also bringing this effort into the Productivity team. The first order of business is to clean up the Evernote integration in the Notes+ app. We have started working on this now with a new contractor on our team.
  • Backlog management: Like other teams, we have found that trying to manage our backlog in Pivotal Tracker has not been very successful. Trying to keep it in sync with Bugzilla proved to be too much overhead. For 1.4, we're moving back into bugzilla with a combination of whiteboards and flags to identify our current and future work. The Pivotal Tracker board will be cleaned out and removed.
