Metro

• Although Metro work is riding the trains, it's all behind an ifdef (MOZ_METRO) which is only turned on in Nightly.
• Current expected work complete date for v1 is November 19th, although it has been moving up due to faster velocity in the recent iterations (so it may move up more).
• Tier 1 status? No, but we will be. The main step in progress towards this is releng work to turn on mochitests (bug 864418).
• Waiting for OMTC to land for a bunch of panning/zooming work.
• Other than OMTC, largely what's remaining for v1 work is front end work.
• Most of the progress from the Metro team is in the form of front end work.
• Elm users (Where Metro development began) have been migrated from elm to m-c.
• Software updates through the Metro interface, will be offered trough the about flyout and silently in the background.
  • Some changes for that included upgrading while another browser from the same install is open.
• May 13th - May 17th will be the 2nd Metro work week in the Vancouver office.
• Sprint 5 and sprint 6 were recently completed, and Sprint 7 is in progress.
