# Release Notes - Versions 0.13.x

## Version 0.13.21

### New Features
* Python 3.15 support

### Bugs Fixed
* Vendored packages and `coverage` failed to import on Python 3.15, which
removed the legacy `load_module()` fallback from the import machinery. Both
of PyBuilder's meta path loaders now implement the PEP 451
`create_module()`/`exec_module()` protocol.
* `packaging` 26.3 gave `Requirement` a `__slots__` layout, breaking the
`project_name` attribute PyBuilder attached to dependency requirements.
Requirement names are now read from `Requirement.name`.

### Removed Features
* Removed compatibility workarounds for Python versions below 3.10

### Vendorized Dependency Upgrades
* Bumped vendorized dependencies, notably:
* virtualenv 20.36.1 to 21.7.4, which splits interpreter discovery into a
separate `python-discovery` package and no longer depends on `click`
* importlib-metadata 8.7.1 to 9.0.0
* packaging 26.0 to 26.3
* importlib-resources 6.5.2 to 7.1.0
* rich 14.3.2 to 15.0.0
* wheel 0.46.3 to 0.48.0
* setuptools to 84.0.0
