Add support to install multiple python versions

In scope of this release we added support to install multiple python versions. For this you can try to use this snippet:

    - uses: actions/setup-python@v4
      with:
        python-version: |
            3.8
            3.9
            3.10

Besides, we changed logic with throwing the error for GHES if cache is unavailable to warn (#566).

Improve error handling and messages

In scope of this release we added improved error message to put operating system and its version in the logs (#559). Besides, the release

• fixes issue about specifying architecture for pypy-nightly on Windows with related pull request.
• improves error handling for Http Errors (#511).
• updates minimatch (#558).

Update actions/core to 1.10.0 for v2

In scope of this release we update actions/core to 1.10.0 for v2 major tag: #533.

v4.3.0

• Update @actions/core to 1.10.0 version #517
• Update @actions/cache to 3.0.4 version #499
• Only use github.token on github.com #443
• Improvement of documentation #477 #479 #491 #492

Add check-latest input and bug fixes

In scope of this release we add the check-latest input. If check-latest is set to true, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, the version will then be downloaded from python-versions repository. By default check-latest is set to false. For PyPy it will to try to reach https://downloads.python.org/pypy/versions.json

Example of usage:

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-python@v4
    with:
      python-version: '3.9'
      check-latest: true
  - run: python --version

Besides, it includes such changes as

• Resolved logs for python-version and file inputs: #465
• Added linux os release info to primary key: #467
• Added fix to change Python versions for poetry: #445
• Fix Tool Path handling for self-hosted runners: #466

v4.1.0

In scope of this pull request we updated actions/cache package as the new version contains fixes for caching error handling. Moreover, we added a new input update-environment. This option allows to specify if the action shall update environment variables (default) or not.

Update-environment input

    - name: setup-python 3.9
      uses: actions/setup-python@v4
      with:
        python-version: 3.9
        update-environment: false

Besides, we added such changes as:

• Allow python-version-file to be a relative path: #431
• Added new environment variables for Cmake: #440
• Updated error message for resolveVersion: #450
• Assign default value of AGENT_TOOLSDIRECTORY if not set: #394

v4.0.0

What's Changed

• Support for python-version-file input: #336

Example of usage:

- uses: actions/setup-python@v4
  with:
    python-version-file: '.python-version' # Read python version from a file
- run: python my_script.py

There is no default python version for this setup-python major version, the action requires to specify either python-version input or python-version-file input. If the python-version input is not specified the action will try to read required version from file from python-version-file input.

• Use pypyX.Y for PyPy python-version input: #349

Example of usage:

- uses: actions/setup-python@v4
  with:
    python-version: 'pypy3.9' # pypy-X.Y kept for backward compatibility
- run: python my_script.py

• RUNNER_TOOL_CACHE environment variable is equal AGENT_TOOLSDIRECTORY: #338

• Bugfix: create missing pypyX.Y symlinks: #347

• PKG_CONFIG_PATH environment variable: #400

• Added python-path output: #405
  python-path output contains Python executable path.

• Updated zeit/ncc to vercel/ncc package: #393

• Bugfix: fixed output for prerelease version of poetry: #409

• Made pythonLocation environment variable consistent for Python and PyPy: #418

• Bugfix for 3.x-dev syntax: #417

• Other improvements: #318 #396 #384 #387 #388

Update actions/cache version to 2.0.2

In scope of this release we updated actions/cache package as the new version contains fixes related to GHES 3.5 (#382)

Add "cache-hit" output and fix "python-version" output for PyPy

This release introduces new output cache-hit (#373) and fix python-version output for PyPy (#365)

The cache-hit output contains boolean value indicating that an exact match was found for the key. It shows that the action uses already existing cache or not. The output is available only if cache is enabled.

The python-version contains version of Python or PyPy.

Support caching poetry dependencies and caching on GHES 3.5

• In the scope of this release, we added support for caching from GHES 3.5 and fixed the download issue for files > 2GB during restore.
• Caching poetry dependencies

steps:
- uses: actions/checkout@v3
- name: Install poetry
  run: pipx install poetry
- uses: actions/setup-python@v3
  with:
    python-version: '3.9'
    cache: 'poetry'
- run: poetry install
- run: poetry run pytest
