Action items

Feature Status Review

• Fx91 Beta (On track)
  • No features identified as challenged or at risk. No known uplifts planned. Looks quiet.
    • status of https://bugzilla.mozilla.org/show_bug.cgi?id=1708455#c19 ?
• Fx 92 Nightly (On Track)
  • Working to finalize feature list. No challenged or at risk callouts from Feature owners.
  • Working to get additonal details around several features; 'WebRTC testing of Facebook group calling', and 'Ship ETP Strict Shimming Phase 3'
  • Both 'run-from-.dmg behavior changes' & 'Package into MSIX' not expected to ship until Fx93. Requested QA support for Fx92.
  • MR 1.1 scope has been scaled down for Fx92. Trying to understand what the new scope is but I would say were looking at 30% or so of the original features/scope.
  • May have some additional features coming from Platform. Team is getting better around their usage of JIRA. See their basic Kanban roadmap; https://mana.mozilla.org/wiki/pages/viewpage.action?pageId=130928588.
