      • CJ reports ~763 packages that use “toolchain” in build deps. MichaelS to get that list from CJ, and will divide into two sets:

        • recipes that have already been done in AnacondaRecipes and should be PR’ed to Conda-forge

        • recipes that need modification for new compilers and remove python as mechanism for activating VC features

  • How do we want the bot to handle non-release releases (alpha/beta/dev/pre/etc.) https://github.com/regro/cf-scripts/issues/86 and https://github.com/conda-forge/conda-forge-enhancement-proposals/pull/3 and https://github.com/conda-forge/matplotlib-feedstock/pull/24#issuecomment-221496870

      • Chatting in the background with Intel about using their compilers on the CI services

      • defaults uses:

        • intel fortran compiler to build SciPy (fortran only; VS used for C/C++)
