Releasing a New Version
=======================

Versions of this project follow `Semantic Versioning 2.0.0 <http://semver.org/>`_.

We use `bump-my-version <https://github.com/callowayproject/bump-my-version>`_ to help update versions, and `towncrier <https://github.com/twisted/towncrier>`_ to generate the changelog.

Requirements
------------

pipx is the recommended way to install the required tools:

.. code-block:: sh

    pipx install bump-my-version
    pipx install towncrier

Using system packages is another option.

New Version
-----------

The parts of the version are: ``{major}.{minor}.{patch}``.

For example, to update the ``patch`` part and generate the changelog (requires python 3.11+ with toml):

.. code-block:: sh

    bump-my-version bump patch
    current_version=$(python3 -c "import tomllib;t = tomllib.load(open('.bumpversion.toml', 'rb'));print(t['tool']['bumpversion']['current_version'])")
    towncrier build --version=$current_version --yes
    hg remove newsfragments
    hg amend
    hg tag $current_version
