Pdm

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

Features & Improvements

- Added a new mode `--json` to the list command which outputs the dependency graph as a JSON document. [583](https://github.com/pdm-project/pdm/issues/583)
- Add a new config `feature.install_cache`. When it is turned on, wheels will be installed into a centralized package repo and create `.pth` files under project packages directory to link to the cached package. [589](https://github.com/pdm-project/pdm/issues/589)

Bug Fixes

- Fix env vars in source URLs not being expanded in all cases. [570](https://github.com/pdm-project/pdm/issues/570)
- Fix the weird output of `pdm show`. [580](https://github.com/pdm-project/pdm/issues/580)
- Prefer `~/.pyenv/shims/python3` as the pyenv interpreter. [590](https://github.com/pdm-project/pdm/issues/590)
- Fix a bug that installing will download candidates that do not match the locked hashes. [596](https://github.com/pdm-project/pdm/issues/596)

Improved Documentation

- Added instructions to the Contributing section for creating news fragments [573](https://github.com/pdm-project/pdm/issues/573)

Removals and Deprecations

- Deprecate `-s/--section` option in favor of `-G/--group`. [591](https://github.com/pdm-project/pdm/issues/591)

Refactor

- Switch to a self-implemented version of uninstaller. [586](https://github.com/pdm-project/pdm/issues/586)
- `pdm/installers/installers.py` is renamed to `pdm/installers/manager.py` to be more accurate. The `Installer` class under that file is renamed to `InstallerManager` and is exposed in the `pdm.core.Core` object for overriding. The new `pdm/installers/installers.py` contains some installation implementations. [589](https://github.com/pdm-project/pdm/issues/589)
- Switch from `pkg_resources.Distribution` to the implementation of `importlib.metadata`. [592](https://github.com/pdm-project/pdm/issues/592)

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

Bug Fixes

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

Features & Improvements

- Support showing individual fields by `--<field-name>` options in pdm show. When no package is given, show this project. [527](https://github.com/pdm-project/pdm/issues/527)
- Add `--freeze` option to `pdm list` command which shows the dependencies list as pip's requirements.txt format. [531](https://github.com/pdm-project/pdm/issues/531)

Bug Fixes

- Switch from `toml` to `tomli`. [541](https://github.com/pdm-project/pdm/issues/541)

Refactor

- Separate the build env into two different levels for better caching. [541](https://github.com/pdm-project/pdm/issues/541)
- Refactor the build part into smaller functions. [543](https://github.com/pdm-project/pdm/issues/543)

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

Features & Improvements

- Extract package name from egg-info in filename when eligible. Remove the patching code of resolvelib's inner class. [441](https://github.com/pdm-project/pdm/issues/441)
- Support installing packages from subdiretories of VCS repository. [507](https://github.com/pdm-project/pdm/issues/507)
