Pdm

---------------------------

Bug Fixes

- Fix a bug that dependencies from different versions of the same package override each other. [1307](https://github.com/pdm-project/pdm/issues/1307)
- Forward SIGTERM to child processes in `pdm run`. [1312](https://github.com/pdm-project/pdm/issues/1312)
- Fix errors when running on FIPS 140-2 enabled systems using Python 3.9 and newer. [1313](https://github.com/pdm-project/pdm/issues/1313)

---------------------------

Features & Improvements

- Add a env_file.override option that allows the user to specify that
the env_file should override any existing environment variables. This
is not the default as the environment the code runs it should take
precedence. [1299](https://github.com/pdm-project/pdm/issues/1299)

- Try to read the lock file even if the lock version is incompatible. [1273](https://github.com/pdm-project/pdm/issues/1273)
- For packages that are only available as source distribution, the `summary` field in `pdm.lock` contains the `description` from the package's `pyproject.toml`. [1274](https://github.com/pdm-project/pdm/issues/1274)
- Do not crash when calling `pdm show` for a package that is only available as source distribution. [1276](https://github.com/pdm-project/pdm/issues/1276)
