+- Deprecate CONDA_LIBMAMBA_SOLVER_NO_CHANNELS_FROM_INSTALLED. No longer needed with v2.
+- Typing in all methods
+- time_recorder for metadata collection and solving loop
+- removed state.BaseIndexHelper
+- The libmamba v1 "pool" (collection of "repos"; repo = loaded repodata.json) is now a "database" of "RepoInfo" objects.
+- Do use current_repodata.json if explicitly set in CLI
