Towncrier 25.8.0

towncrier 25.8.0 (2025-08-30)

Features

• Support was added for Mercurial SCM. ([#394](https://github.com/twisted/towncrier/issues/394) <https://github.com/twisted/towncrier/issues/394>_)
• The towncrier check command now has a --staged flag to inspect the files staged for commit when checking for a news fragment: useful in a pre-commit hook ([#676](https://github.com/twisted/towncrier/issues/676) <https://github.com/twisted/towncrier/issues/676>_)
• When used with an pyproject.toml file, when no explicit values are defined for [tool.towncrier.name|package] they will now fallback to the value of [project.name]. ([#687](https://github.com/twisted/towncrier/issues/687) <https://github.com/twisted/towncrier/issues/687>_)
• More simple configuration for Keep a Changelog style changelogs ([#691](https://github.com/twisted/towncrier/issues/691) <https://github.com/twisted/towncrier/issues/691>_)
• Added support for Python 3.13 and removed support for Python 3.8. ([#700](https://github.com/twisted/towncrier/issues/700) <https://github.com/twisted/towncrier/issues/700>_)

Bugfixes

• Multi-line newsfragments that ends with a code block will now have a newline inserted before appending the link to the issue, to avoid breaking formatting. ([#614](https://github.com/twisted/towncrier/issues/614) <https://github.com/twisted/towncrier/issues/614>_)
• Markdown header level is correctly inferred from title_format. ([#695](https://github.com/twisted/towncrier/issues/695) <https://github.com/twisted/towncrier/issues/695>_)

Improved Documentation

• The documentation RST source files are now included in the sdist package. ([#672](https://github.com/twisted/towncrier/issues/672) <https://github.com/twisted/towncrier/issues/672>_)
• Refactor the default markdown template to make it easier to understand, extend, and customize. ([#706](https://github.com/twisted/towncrier/issues/706) <https://github.com/twisted/towncrier/issues/706>_)

Deprecations and Removals

• When no sections are present, the default Markdown template now renders the category headers as H2. In previous versions it was rendered as H3. ([#663](https://github.com/twisted/towncrier/issues/663) <https://github.com/twisted/towncrier/issues/663>_)
