conda env update would ask for user input and hang when working with pip installs of git repos and the repo was previously checked out. Tell pip not to ask for user input for that case. (#11818)
Fix for conda update and conda install issues related to channel notices. (#11852)
Signature verification printed None when disabled, changes default metadata_signature_status to an empty string instead. (#11944)
Fix importlib warnings when importing conda.cli.python_api on python=3.10. (#11975)
Several user facing MatchSpec crashes were identified by fuzzing efforts. (#11999)
Apply minimal fixes to deal with these (and similar) crashes. (#12014)
Prevent conda from using /bin/sh + exec trick for its own entry point, which drops $PS1 on some shells (#11885, #11893 via #12043).
Handle CTRL+C during package downloading more gracefully. (#12056)
Prefer the outer name when a MatchSpec specifies a package's name twice package-name[name=package-name] (#12062)

Add a pending deprecation warning for when importing tqdm from conda._vendor. (#12005)
Drop ruamel_yaml and ruamel_yaml_conda in favor of ruamel.yaml. (#11837)
context.experimental_solver is now marked for pending deprecation. It is replaced by context.solver. The same applies to the --experimental-solver flag, the CONDA_EXPERIMENTAL_SOLVER environment variable, and the ExperimentalSolverChoice enum, which will be replaced by --solver, EXPERIMENTAL_SOLVER and SolverChoice, respectively. (#11889)
Mark context.conda_private as pending deprecation. (#12101)
