Blender 2.82 bcon3

  • Original plan is to move to bcon3 this Thursday (9/1)
  • Grease Pencil / annotation patch needs review by then - D6467
  • Lukas Stockner says at least one UDIM patch needs review, specially the Eevee/Workbench patch (D6456) - other patches: D6465 (simple), D6492 (packing, more complex, not priority) - Clement will try to look at it
  • Lukas will also work in UDIM manual in the coming days
  • Pablo Dobarro wants the IK pose brush (D6389) to be in bcon3

Blender 2.83 bcon1

  • Time when consider what to schedule in the modules roadmaps let’s remember of the tracker curfew
    (so devs are expected to work 2 full days a week with bug triaging, fixing and patch review)
    This will impact the inflow of new features, but it is temporary
