  • (Planned) Lightning talk - governance updates

New Agenda Items

• (JRG) CEP: Technical specification for creation, modification and deletion of conda environments

  • PR
  • (MRB+others) We don't want breaking changes in this CEP. We want to decide what is a core spec and what is not.

• (MRB) Any updates on sha256 and/or .conda?

  • (CHL) .conda support live in prod; upload supported with anaconda-client 1.10.0
  • (CHL) Still verifying .conda packages sync to CDN for conda-forge, bioconda, etc.
  • (CHL) SHA256 completed development; in testing, should be rolled out in next release

• (DPC) Fiscal Sponsorship application is due in 9 days.

  • Will submit a vote call today.
  • Will submit application by deadline
  • Will withdraw if vote does not pass
  • Will combine with governance vote into a single vote.
  • Vote will be open for two weeks.

• (DJC) Should higher build numbers always take precedence when package version is the same? i.e. how to make cuda variants preferred over non-cuda variants?

  • https://github.com/conda/conda/issues/11581
  • Conda-forge docs imply this works for MPI variants https://conda-forge.org/docs/maintainer/knowledge_base.html#mpi-variants-in-conda-forge
  • Could add track_features to deprioritize, but that's kinda(?) discouraged. This is the behavior used in conda-forge for things like "python *pypy", "arrow-cpp *-cuda"

• (JRG) conda-libmamba-solver 22.6 is out!

  • It works on your base environment!
  • Compatible with conda-build
  • Some fixes and performance improvements
  • (MRB) how is mamba pinned for this one? are we post 0.24 so we don't break things for other bugz?

• (KK) CEP: conda Capitalization

  • https://github.com/conda-incubator/ceps/pull/31

• (DPC) PSA: Communication channel consolidation?

  • We have too many places for people to ask questions / make announcements relevant to conda.
  • Look for a proposal later this summer.

• (KO) CEP: Conda Release Schedule

  • https://github.com/conda-incubator/ceps/pull/26
  • Proposes bimonthly regular releases (Janurary, March, May, July, September, November)
  • Proposes using CalVer (YY.MM.MICRO)
  • We are planning to cut a new conda release (4.14.0/22.7.0) by the end of July

What is this meeting for?

Various parts of the conda community gather on a regular basis. This meeting brings together all of these sub-communities for a community wide call.
