Blender 2.83.1 LTS

  • Post-mortem, main outcome is that cherry-picking issues is getting complicated.
  • Proposal: original developers to be contacted by the LTS maintainer to help merging.
  • This wasn’t received so well since it will add burden to the core-team.
  • There were no conclusions and Dalai Felinto, Jeroen Bakker and Sergey will discuss this internally.


  • Dalai proposes to have a 2-week long bug sprint as part of the regular release cycle after bcon2.
  • There was no consensus on the best way of handling this, if it should be handled per-module or when to happen.
  • A clear proposal will be posted on bf-committers for discussion later.

Google Summer of Code

  • This week (29/Jun 18h CEST - 03/Jul 18h CEST) is the first evaluation period.
  • All mentors to fill in their reports.
  • Mentors that need help assessing the student work poke Dalai for help.
