    The cache for PythonInfo is now invalidated if the PythonInfo class changes. I achieved this by hashing the py_info.py file and storing the hash in the cache. When loading from the cache, the hash is recomputed and compared with the stored hash. If they don't match, the cache is invalidated.

          Seems this is a valid error, you'll need to fix it.  | 
    
* Add `encoding="utf-8"` to `subprocess.run` calls in `tests/unit/discovery/test_discovery.py` for consistent text handling. * Update assertion in `tests/unit/discovery/py_info/test_py_info.py` to handle potential multiple calls on Homebrew installations. * Ensure consistent text encoding across subprocess executions in discovery tests.

           That linter rule is dumb. It will be happier if I completely remove the comment leaving everybody in the dark. Should I remove it?  |
