Stability dashboard data has been signed off by Kairo.
He believes that this is no longer a blocker for deploying e10s to beta "permanently" (all 6 weeks of the cycle)
Final production-quality dashboards have not been built, but there are a bunch of prototypes which can be used to answer questions now see https://public.etherpad-mozilla.org/p/kairo-telemetry-notes and https://sql.telemetry.mozilla.org/dashboard/stability-dashboard-for-release-tracking
In particular for e10s, see https://sql.telemetry.mozilla.org/queries/177 - e10s crash rate is still 3x control
For 47 beta, really want bug 1265015 - may need help from EPMs getting proper urgency/traction

Mostly working on using firefox.exe for everything. Should have a patch by the end of today or tomorrow.
Per-process texture pool: have some preliminary patches and some good feedback from nical and mattwoodrow. Working on this in the background.
