towncrier 21.3.0.rc1 (2021-03-21)

Features

- Ticket number from file names will be stripped down to avoid ticket links such as ``#007``. (`#126 <https://github.com/hawkowl/towncrier/issues/126>`_)

- Allow definition of the project ``version`` and ``name`` in the configuration file.

This allows use of towncrier seamlessly with non-Python projects. (`#165 <https://github.com/hawkowl/towncrier/issues/165>`_)

- Improve news fragment file name parsing to allow using file names like

``123.feature.1.ext`` which are convenient when one wants to use an appropriate

extension (e.g. ``rst``, ``md``) to enable syntax highlighting. (`#173 <https://github.com/hawkowl/towncrier/issues/173>`_)

- The new ``--edit`` option of the ``create`` subcommand launches an editor for entering the contents of the newsfragment. (`#275 <https://github.com/hawkowl/towncrier/issues/275>`_)

- CPython 3.8 and 3.9 are now part of our automated test matrix and are officially supported. (`#291 <https://github.com/hawkowl/towncrier/issues/291>`_)

- When searching for the project, first check for an existing importable instance.

This helps if the version is only available in the installed version and not the source. (`#297 <https://github.com/hawkowl/towncrier/issues/297>`_)

- Support building with PEP 517. (`#314 <https://github.com/hawkowl/towncrier/issues/314>`_)

Bugfixes

- Configuration errors found during command line execution now trigger a message to stderr and no longer show a traceback. (`#84 <https://github.com/hawkowl/towncrier/issues/84>`_)

- A configuration error is triggered when the newsfragment files couldn't be discovered. (`#85 <https://github.com/hawkowl/towncrier/issues/85>`_)

- Invoking towncrier as `python -m towncrier` works. (`#163 <https://github.com/hawkowl/towncrier/issues/163>`_)

- ``check`` subcommand defaults to UTF-8 encoding when ``sys.stdout.encoding`` is ``None``.

This happens, for example, with Python 2 on GitHub Actions or when the output is piped. (`#175 <https://github.com/hawkowl/towncrier/issues/175>`_)

- Specifying ``title_format`` disables default top line creation to avoid duplication. (`#180 <https://github.com/hawkowl/towncrier/issues/180>`_)

Improved Documentation

- The README now mentions the possibility to name the configuration file

``towncrier.toml`` (in addition to ``pyproject.toml``). (`#172 <https://github.com/hawkowl/towncrier/issues/172>`_)

- ``start_line`` corrected to ``start_string`` in the readme to match the long standing implementation. (`#277 <https://github.com/hawkowl/towncrier/issues/277>`_)
