Roundtable

• [RyanVM] Concerns about missing symbols from DevEdition 57b1/b2 builds and overall crash rate monitoring during that week
  • No monitoring on the Socorro side for crash reports that it can't symbolicate (has also burned us on OSX previously)
  • Crash stats dashboards didn't really have the DevEdition rates anywhere obvious
  • Calling DevEdition version b0 makes it hard to discern trends between versions
    • Marco C worked on that, we (RM) have some alerts, we can extend that
  • (callek) Task Configuration Change https://bugzilla.mozilla.org/show_bug.cgi?id=1403970 is one option to reduce the chance of missing this when creating or modifying jobs.

• READ ONLY [elan] We have three quick-turnaround product integrity requests for SV from the Shield team, you should be seeing requests soon:

   1) enrollment add-on (Pioneer related)
   2) 57 satisfaction survey (must get deployed during 56 Release) 
   3) Search related experiment 

• READ ONLY [selena] milan is asking for us *not* to update any Windows 7 Pre-SP1 with 64-bit -- catlee asked us to notify liz
  • that wn't be happening till next week anyway at the earliest , talk with romain and cpeterson ok great thanks
• mtabara - RelEng automation needs some buffer time to update all resources and propagate. I think we should not block the release on WNP issues. We can tackle that after
