1.5.0

Bug fixes

• An incorrect signature of the __class_getitem__ class method
  has been fixed, adding a missing class_item argument under
  Python 3.8 and older.

  This change also improves the code coverage of this method that
  was previously missing -- by :user:webknjaz.

Improved documentation

• Rendered issue, PR, and commit links now lead to
  frozenlist's repo instead of yarl's repo.

  #573.

• On the :doc:Contributing docs <contributing/guidelines> page,
  a link to the Towncrier philosophy has been fixed.

Packaging updates and notes for downstreams

• A name of a temporary building directory now reflects
  that it's related to frozenlist, not yarl.

• Declared Python 3.13 supported officially in the distribution package metadata.

1.4.1

Packaging updates and notes for downstreams

• Declared Python 3.12 and PyPy 3.8-3.10 supported officially
  in the distribution package metadata.

  Related issues and pull requests on GitHub:
  #553.

• Replaced the packaging is replaced from an old-fashioned :file:setup.py to an
  in-tree :pep:517 build backend -- by :user:webknjaz.

  Whenever the end-users or downstream packagers need to build frozenlist
  from source (a Git checkout or an sdist), they may pass a config_settings
  flag pure-python. If this flag is not set, a C-extension will be built
  and included into the distribution.

  Here is how this can be done with pip:

  .. code-block:: console

  $ python3 -m pip install . --config-settings=pure-python=
  

  This will also work with -e | --editable.

  The same can be achieved via pypa/build:

  .. code-block:: console

  $ python3 -m build --config-setting=pure-python=
  

  Adding -w | --wheel can force pypa/build produce a wheel from source
  directly, as opposed to building an sdist and then building from it.

Contributor-facing changes

• It is now possible to request line tracing in Cython builds using the
  with-cython-tracing :pep:517 config setting
  -- :user:webknjaz.

  This can be used in CI and development environment to measure coverage
  on Cython modules, but is not normally useful to the end-users or
  downstream packagers.

  Here's a usage example:

  .. code-block:: console

  $ python3 -Im pip install . --config-settings=with-cython-tracing=true
  

  For editable installs, this setting is on by default. Otherwise, it's
  off unless requested explicitly.

  The following produces C-files required for the Cython coverage
  plugin to map the measurements back to the PYX-files:

  .. code-block:: console

  $ python -Im pip install -e .
  

  Alternatively, the FROZENLIST_CYTHON_TRACING=1 environment variable
  can be set to do the same as the :pep:517 config setting.

• Coverage collection has been implemented for the Cython modules
  -- by :user:webknjaz.

  It will also be reported to Codecov from any non-release CI jobs.

  Related issues and pull requests on GitHub:
  #561.

• A step-by-step :doc:Release Guide <contributing/release_guide> guide has
  been added, describing how to release frozenlist -- by :user:webknjaz.

  This is primarily targeting the maintainers.

• Detailed :doc:Contributing Guidelines <contributing/guidelines> on
  authoring the changelog fragments have been published in the
  documentation -- by :user:webknjaz.
