reticulate Files

The S3 classes for some (rarely encountered) Python objects have changed. Only Python objects with non-standard __module__ values are affected. If a Python object’s parent class’s __module__ attribute does not resolve to a string, reticulate:

• Attempts to resolve it from the class's class, if it's a metaclass.
• If no string can be resolved, reticulate no longer implicitly prepends 'python.builtin.' as the class prefix, instead it uses just the __name__. (See [#1686] for more context)

Added support for Python 3.13. Note that Python 3.13 removed support for classmethod descriptors, which may affect the S3 class of some Python objects that use metaclass properties to resolve a class’s __module__ or __name__ attribute. (#1686, [#1698])

py_is_null_xptr() and [[ now load delayed modules (#1688).

Fixed error when attempting to use a python venv created with uv (#1678)

Resolved an issue where py_discover_config() attempted to detect Windows App Store Python installations. These are now excluded from discovery by both py_discover_config() and virtualenv_starter() (#1656, [#1673]).

Fixed an error when converting an empty NumPy char array to R (#1662).

Fixed an error when using reticulate with radian (#1668, [#1670]).

Fixed a segfault encountered when running the Python session finalizer (#1663, [#1664]).

Resolved a segfault in RStudio when rapidly switching between R and Python chunks in a Quarto document (#1665).

Improved behavior when the conda binary used to create an environment cannot be resolved (contributed by @tl-hbk, [#1654], [#1659]).

Added Positron support for the Variables Pane and repl_python() (#1692, [#1641], [#1648], [#1658], [#1681], [#1687]).
