+## 23.7.4 (2023-09-12)

+* Fix performance regression of basic commands (e.g., `conda info`) on WSL. (#13035)
+* Catch `PermissionError` raised by `conda.cli.find_commands.find_commands` when user's `$PATH` contains restricted paths. (#13062, #13089)
+* Fix sorting error for `conda config --show-sources --json`. (#13076)
