### New Agenda Items

- [CHL] Update on mamba/libsolv integration
- As of Monday, down to ~5 failing tests
- We should probably re-visit the solver behavior, especially assumptions and implicit constraints
- mamba implemented `track_features` for down-weighting
- `track_features` only ever used in Anaconda's `free` channel
- https://www.anaconda.com/blog/understanding-and-improving-condas-performance:
> Prioritize solutions that minimize the number of “track_features” entries in the environment. Track_features are legacy metadata once used for lining up mkl and debug packages. They are deprecated in general, but are still sometimes used to effectively implement a default variant of a package by “weighing down” alternatives with track_features.
- [CHL] okay with mamba never implementing `track_features` (already deprecated)
- libsolv: provides, recommends; optional deps; deps based on os; pip extras
- https://github.com/conda/conda/pull/10983

- Proposed enhancements:
- [MvN,FF]: proposing a formal conda-lock spec
- https://github.com/mamba-org/mamba/issues/1209
- Possibly move environment history file to JSON- or YAML-format
- New recipe format (boa)

- [FF] pip build-in tree
- https://github.com/conda/conda-build/pull/4294 -> pip upstream not going solve it
- conda-build breaks with pytoml, poetry, etc.
- E.g., https://github.com/conda-forge/staged-recipes/pull/16643/files
- work around: `--use-deprecated=out-of-tree-build`

- [CEP-8](https://github.com/conda/ceps/pull/8/files): draft implementation being worked on
