[marcia]

• Explosiveness report is quiet: https://crash-analysis.mozilla.com/release-mgmt/2017-07-31/2017-07-31.firefox.release.explosiveness.html
• Not much actionable in the top 10. Some shutdown hangs and JS crashes, Websense, etc

[marcia]

• Mobile rate looks good across all three channels
• Nightly #2 browser crash https://bugzilla.mozilla.org/show_bug.cgi?id=1384828 has a patch

Roundtable

[elan] multi for 55 is a 'go'

• We will deal with any regressions as they come. Risk areas continue to be stability, re:TCP Fast open pref on (occasionally), 20% of Nightly has stylo on

[marcia]

• Tracking Talos Regressions?
  • [ritu] Makes perfect sense to do it, we should triage and track them and mark them as blockers if need be
  • [kevin] Makes sense to mark the branches affected when the bug is filed
