v2.11.0

Features & Improvements

• Officially drop the support for Python 3.7.
• Allow exporting current project as editable dependency with pdm export. #1910
• Improve the lockfile compatibility checking by using 3-digit version numbers. This can distinguish forward-compatibility and backward-compatibility. #2164
• Add --skip-existing to pdm publish to ignore the uploading error if the package already exists. #2362
• Use ==major.minor.* as default requires python for application projects. #2382
• We now use the package-type field in the tool.pdm table to differentiate between library and application projects. #2394
• Add support for {pdm} placeholder in script definitions to call the same PDM entrypoint #2408
• When exporting requirements, record the environment markers from all parents for each requirement. This allows the exported requirements to work on different platforms and Python versions. #2418
• pdm lock now supports --update-reuse option to keep the pinned versions in the lockfile if possible. #2419
• Introduce a new lock strategy inherit_metadata to inherit and merge markers from parent requirements. This is enabled by default when creating a new lockfile. #2421
• New cache methods: symlink_individual for creating a symlink for each individual package file and hardlink for creating hardlinks. #2425
• Add "pdm sync" pre-commit hook #2474
• New update strategy: reuse-installed. When this strategy is enabled, PDM will try to reuse the versions already installed in the environment, even if the package names are given in the command line following add or update. This strategy is supported by add, update and lock commands. #2479
• Show subcommand's help info when passing unrecognized arguments. #2480
• add PDM_CACHE_DIR environment variable to configure cache directory location. #2485

Bug Fixes

• Use the same order of Python interpreters as interactive mode in pdm init -n. #2436
• pdm init now implies --lib if --backend is passed. #2437
• Fix a bug that link collection ignores package-index-binding. #2442
• Fix the wrong installation candidates for different architectures on Windows. #2464
• Fix installing PEP 561 stub-only packages with install.cache_method = "symlink". #2466
• Fix a KeyError raised by pdm update --unconstrained when the project itself is listed as a dependency. #2483

v2.10.4

Bug Fixes

• Do not detect as requirements.txt if the file is a python script. #2416
• Provide information of the original line when parsing requirement fails. #2417
• Resolve -r requirements paths relative to the requirement file they are specified in #2422
• Updating package now overwrites the old files instead of removing before installing. #2423

v2.10.3

Bug Fixes

• Create virtualenv for conda base Python. #2409

v2.10.2

Features & Improvements

• Log the response text when pdm publish fails with HTTP error. #2400

Bug Fixes

• Improve the error message when a specific package can't be found in the lockfile. #2358
• prevent wrong project name (including space and illegal characters) #2360
• Fix a bug that PDM cannot detect namespace packages correctly when creating symlinks. The package's __init__.py contains an unusual line. #2378
• Fix template files created by pdm init being read-only when copied from a read-only PDM installation. #2379
• Don't reset the build backend when asking for import. #2388
• Never wrap the output of the export command. #2390
• Forbid global project in conda base environment, since it may remove conda-managed packages. #2409

v2.10.1

Bug Fixes

• Fix a bug preventing ctrl-c from interrupting program execution on 2nd invocation when using "pdm run" (Windows only). #2292
• Fix list index out of range when build error message is empty. #2337
• Fix find_link sources being exported as --extra--index-url #2342
• Fix an installation failure when install.cache = true. #2355

Documentation

• Set up a chatbot powered by LLM on the doc page. #2365
