• [ON TRACK] APZC on B2G apps
• [ON TRACK] Metro
• [ON TRACK] E10S
• [ON TRACK] Australis TART
• [ON TRACK] The GFX team will resolve all actionable security bugs within six weeks of their entering our components and receiving sec-high or sec-critical designation. [7] (All trains)

Layout

• [ON TRACK] Vertical Text - Basic logical geometry and writing mode API landed
• [ON TRACK] HarfBuff text shaping - performance and correctness update
• [ON TRACK] HTML5 Form input type (number)
• [ON TRACK] CSS Variables landed on mozilla-central
• [ON TRACK] Multi-line CSS Flexbox landed and enabled on mozilla-central

• [DONE] have our own CSS parsing and selector matching code in Servo

Media

2. [DONE] Fragmented MP4 Parser
3. [DONE] WebM VP9 Support

DOM

• [DONE] Norway worker work (bug 916204) (dougt / khuey / nikhil)
  • This ended up being basically no work, but a bunch of discussions to further understand the needs of the gaia team. In the end it resulted in no JS API implemented APIs exposed to workers, but some of those APIs are being exposed by converting their implementations to C++
• [DONE] E10s and B2g work related to message manager and event handling (olli) (significant work done, but more stuff may come up)
• [ON TRACK] add some helper code to deal with cross-thread cycles, (bug 915097 and others) (olli)
• [ON TRACK] fix AppShell's favorPerfMode (bug 822096 and others )(olli)
• [DEFER] Update document.register to latest spec revision (bug 856140) (blake / wchen)

• [ON TRACK] Implement ShadowRoot event retargeting algorithm (bug 887541) (blake / wchen)
• [ON TRACK] ShadowRoot <shadow> element (bug 887538) (blake / wchen)
• [MISSED] Implement HTML imports (bug 877072) (blake / wchen)
  • A bulk of this work got done, but other work got in the way and was of higher priority than this work.
• [ON TRACK] Finalize the patch for per-document,docshell,window event queue (olli)
• [ON TRACK] Service Workers (nikhil)
• [DONE] Think about Push payload (nikhil)
  • This ask went away, so we ended up really not doing any work here, but we did deal with this situation.
• [ON TRACK] ICC landed but not turned on.
• [MISSED] Deal with all the main bullet items in our Window bindings task list
  • Large parts of this is done, but we ran into unexpected complications along the way that took more time than expected to get through, so this won't be done for the end of Q4
• [ON TRACK] Ensure that the median age of all DOM sec-critical and sec-high bugs is 3 weeks or less.

• [WISHLIST] Land (async) IDB in workers (bug 701634) (baku)
  • this ate up most of baku and bent's time and will likely land very early in 2014
