New Agenda Items

• (DG) Anaconda Survey: https://anaconda.surveymonkey.com/r/usrfdbk
• (DG) Anaconda package data is now updated and available on https://github.com/ContinuumIO/anaconda-package-data
  • See context & previous discussions here: https://github.com/ContinuumIO/anaconda-package-data/issues/45
  • Added tracking of .conda artifacts
  • Discovered and fixed double counting from requests to CDN
• (JRG) Playing with conda activation stuff (inspired by pixi shell): https://github.com/conda-incubator/conda-spawn
  • WV: If --sandbox Python bindings become available, this could be integrated nicely.
• (JRG) conda.org goodness! Can we use it for Bluesky and schemas.conda.org?
  • Subnote: the steering council should have ownership of conda/schemas, imo.
• (JRG) Looking forward to starting the vote for two upcoming CEPs:
  • Frozen environments: https://github.com/conda/ceps/pull/99
  • Virtual packages: https://github.com/conda/ceps/pull/103
• (BZ) Will Anaconda support sharded repodata on conda.anaconda.org?

    • This conda-index PR: https://github.com/conda/conda-index/pull/161
    • Finish CEP for run exports in shared repodata
  • (CHL/DG) Would like to, but we don't have resources and timelines as of today.
• (WV) Can give a quick demo of building a feedstock with pixi-build
  • JRG: Discuss whether this requires feedstock directory structure standardization via a CFEP (at least the location of conda-forge.yml?)
