- Only check lower bound on conda/mamba, upgrade unbounded if not matched (let conda apply upper bound according to existing pins, such as Python) - handle missing mamba - avoid upgrading Python by aborting the install, instead of keeping old envs - minimum supported Python for user env is 3.9 - Fix output reporting of conda install step (no need for json capture when we don't parse the output - exit codes will do)
