Special section about 38.0.6

(sylvestre) * funnelcake => is it still a thing? (similar to partner repack)

• testing of funnelcake
• automation on search test
• is there a list of these?
  • we should have a list of the partner somewhere

39.0

• (bhearsum) EMEFree should user mozilla- prefix (is there a bug?). Shipped in 38
  • If we rename the channel, do we need a special mar? https://bugzilla.mozilla.org/show_bug.cgi?id=1183734

• (bhearsum) win64 builds completely missed as part of 39.0
  • did we have a tracked bug? https://bugzilla.mozilla.org/show_bug.cgi?id=1180792
    • will do for 40 + update the download page to propose this build to adv users
      • maybe communication on 42 or 43 - Javaun is the guy in charge

• (UA - Robert) Malware Crash Post-Mortem: https://docs.google.com/document/d/1d-m-CmumtDSlNNMRQiWf2IOC9_zgtFjnmblXJAfI3KM/edit#
  • If we want a faster response we should foster better relationships with AV companies to get files early and without having to rely on users
  • (Alternatively we could have better file collection utils built-in, but that'd be a lot of work / potential new attack vector / etc)
    • relman has some contacts with AV

• UA needs to work on making their surveys look more official

• (KaiRo) As inconvenient the scrambling around the adware startup crash was, and as unsatisfactory overall the "solution" might feel, this story was a good example of our RC process at work, thanks for everyone involved to make it work!
  • especially during the Workweek
  • however, we would have to improve the internal communication

• (lmandel) We shipped 39.0 two days late. Might be the first time that we've found a critical issue and fixed it before release.

• (lmandel) We did a better job of limiting feature uplifts in this cycle (congrat liz)
  • suggested tiles

• (lmandel) Whistler made it difficult to shutdown the release due to the late issue that was found. It would probably be preferable to have the all-hands in the middle of the cycle rather than at the beginning or end.
  • but it will be the same in Orlando

• (rituk) Short beta cycle - 5 weeks instead of 6 weeks. Kudos! Does that mean we can ship every 5 weeks now?!
  • This might be because 39 did not include several features. Another release would have had an impact due to a shorter cycle.
