Minutes

Present: JB, DD, CW, KS, DH, IM, FA, PB, UZ, JHC, JK

Apologies:

JB/UZ: ngsPETSc releases

JB/UZ are getting issues associated with petsc4py, specifically with numpy version. Hopefully, petsc4py developers can help to fix it. Perhaps a manual release can be done for now.

CW: Python 3.10 for loopy

Andreas has indicated that loopy will be moving to Python 3.10 soon. Do we follow? If we don't then we might need to pin to a pymbolic git hash instead of a version.

DH is fine to drop python 3.9.

CW: Slack channel for developers?

I don't want to bother 650 people when our docs fail to build etc...

DH thinks is good to make the community aware of the firedrake developers' questions/discussions.
