• (CHL) Proposals to drop Python 2.7, < 3.6 support

  • conda: https://github.com/conda/conda/issues/10180
  • conda-build: https://github.com/conda/conda-build/issues/4024
  • Looking at next major version release; ~2020-Q4 or 2020-Q1
  • Possibly consider 3.7 for encoding-related PEPs; choice will depend on how close we are to upstream EOL date for 3.6

• OVH VM: created with the communicated specs. Need to follow up with OVH about getting access.

  • People who need access need to create OVH accounts. Their accounts will be added as maintainers of that project.
    • Should probably manage with terraform
  • Add OVH to this yaml: https://github.com/conda-forge/conda-forge.github.io/blob/master/src/inst_partners.yaml
  • Render that yaml into jinja2

• (SC) R bindings for mamba: https://github.com/marimeireles/rhumba

  • Screencast: https://user-content.gitter-static.net/eb15dbe3c06bffa8af391f8f58f90240efd15cd5/68747470733a2f2f757365722d696d616765732e67697468756275736572636f6e74656e742e636f6d2f31373630303938322f38393636393235362d61376536626130302d643863652d313165612d383637362d3333313130386532386561322e676966
