What's Changed

Breaking Changes

• Editable dependencies in the [project] table is not allowed, according to PEP 621. They are however still allowed in the [tool.pdm.dev-dependencies] table. PDM will emit a warning when it finds editable dependencies in the [project] table, or will abort when you try to add them into the [project] table via CLI. #1083
• Now the paths to the global configurations and global project are calculated according to platform standards. #1161

Features & Improvements

• Add support for importing from a setup.py project. #1062
• Switch the UI backend to rich. #1091
• Improved the terminal UI and logging. Disable live progress under verbose mode. The logger levels can be controlled by the -v option. #1096
• Use unearth to replace pip's PackageFinder and related data models. PDM no longer relies on pip internals, which are unstable across updates. #1096
• Lazily load the candidates returned by find_matches() to speed up the resolution. #1098
• Add a new command publish to PDM since it is required for so many people and it will make the workflow easier. #1107
• Add a composite script kind allowing to run multiple defined scripts in a single command as well as reusing scripts but overriding env or env_file. #1117
• Add a new execution option --skip to opt-out some scripts and hooks from any execution (both scripts and PDM commands). #1127
• Add the pre/post_publish, pre/post_run and pre/post_script hooks as well as an extensive lifecycle and hooks documentation. #1147
• Shorter scripts listing, especially for multilines and composite scripts. #1151
• Build configurations have been moved to [tool.pdm.build], according to pdm-pep517 1.0.0. At the same time, warnings will be shown against old usages. #1153
• Improve the lock speed by parallelizing the hash fetching. #1154
• Retrieve the candidate metadata by parsing the pyproject.toml rather than building it. #1156
• Update the format converters to support the new [tool.pdm.build] table. #1157
• Scripts are now available as root command if they don't conflict with any builtin or plugin-contributed command. #1159
• Add a post_use hook triggered after succesfully switching Python version. #1163
• Add project configuration respect-source-order under [tool.pdm.resolution] to respect the source order in the pyproject.toml file. Packages will be returned by source earlier in the order or later ones if not found. #593

Bug Fixes

• Fix a bug that candidates with local part in the version can't be found and installed correctly. #1093

Dependencies

• Prefer tomllib on Python 3.11 #1072
• Drop the vendored libraries click, halo, colorama and log_symbols. PDM has no vendors now. #1091
• Update dependency version pdm-pep517 to 1.0.0. #1153

Removals and Deprecations

• PDM legacy metadata format(from pdm 0.x) is no longer supported. #1157

Miscellany

• Provide a tox.ini file for easier local testing against all Python versions. #1160
