30 March 2020

Notes for meeting of Monday, 30 March 2020. 18:00 CEST / UTC 16:00 on #blender-coders on blender.chat.


  • Google Summer of Code students deadline is March 31st, don’t miss the deadline.
  • blender.chat server will be updated Monday (march 30th) night.


  • Dalai Felinto suggests “threaded discussions” to be brought back to blender.chat with the update. It helps 1:1 discussions to happen in the public open channels.
  • Also he will try to post on #blender-coders more often the outcome of the talk with the other developers (e.g., a compilation of the daily report of activity by the developers).
  • As a rule of thumb all the developers are heavily encouraged to use the open channels as much as possible (as oppose to private messages).


  • Germano Calvalcante insists a 2.82b release would be benefitial. He will post on bf-committers about that.
