New Agenda Items

• [CJW] Deprecation of old conda versions, ~= and = matchspec not supported by older conda versions. Having repodata entries with these cause old conda to be unable to update envs.
  • To some extent conda-forge can do this by itself via repodata patches, but community consensus would be much better
  • SA: hmmm, reconciliation repodata with a matching specification version for the current environment, with that data being sufficient for conda update (then you're hosting small additional amounts of repodata per spec version). probably has to be paired with minimal override conda settings?
  • JRG: It would work like conda update -c recovery conda or similar.
  • All: deprecation cycle for conda?!
  • JL: And in general, better communication towards the community. CLI notices?
  • JRG: This was introduced in 3.20.5.
    • -This should be reverted until versioned repodatas are actually taken into account.-
    • Alternative: update conda index to generate specs compatible with older releases.
