Announcements

• CHL: Conda SC - starting vote on PURL CEP
• TH: Cool dashboard focused on staged-recipe turn around times and other various statistics: https://nodtem66.github.io/cfsr-stats/

New agenda items

• (HV, in absentia) Go/no-go for dropping py3.10, migrating for 3.15:
  • https://github.com/conda-forge/conda-forge.github.io/pull/2923
  • https://github.com/conda-forge/conda-forge-pinning-feedstock/pull/8891
  • Feel free to modify/merge at will from my (=HV) side
  • (IF) Generally drop version to be EOL when RC1 of new version comes along; minimize strain on CI resources so we're not building for 6 Python versions
• TH: prototypefund.de
  • Program partially funded by the German government (requires at least one team participant to have residency in Germany)
  • Two tracks that could be interesting for funding conda-forge related projects:
    • https://www.prototypefund.de/en/resilience
    • https://www.prototypefund.de/en/innovation
  • Do others feel like conda-forge could be a good match for this program?
  • If so, would anyone be interesting in writing an application for this program together as a team? (I think we could come up with some neat ideas!)
  • Application period is between 2026-10-01 and 2026-11-30
• BZ: Update on publishing conda-forge packages directly to prefix.dev
  • We are working on "groups". conda-forge will be a group that can host multiple channels. Core members will be added as owners to this group.
  • We have a prototype that allows copying packages from a URL into a channel. All using graphQL.
  • The call is async it returns a job that can be queried for changes or just left alone.
  • A temporary channel will be created e.g. conda-forge/staging to which we will copy the packages. If this all works as expected we can switch the mirroring.
  • The call requires the API key of a core member, this can be scoped to specificly this operation and only on this channel.
  • In the future a frontend is added to view job states.
• LH: linux-riscv64 / libffi review
  • blocking many other feedstocks; how do we get it moving?
  • https://github.com/conda-forge/libffi-feedstock/pull/63 (just merged, thanks @isuruf!)
• IF: rattler-build not running tests
  • https://github.com/prefix-dev/rattler-build/pull/2769
• BZ: microrattler preview
  • A blazingly fast drop in replacement for conda but built natively in rust using rattler.
  • Will contribute to conda-incubator soon(TM).
