The version of towncrier is not pinned in CI so lately the rendering of the changelog is broken in the unstable version (note the changelog categories that are now numbered titles):
This is due to twisted/towncrier#483 that is included in towncrier 23.6.0.
The first commit fixes that by replacing the default template by a custom one. It also allows to put formatting in the template only rather than in the config file.
The second commit allows to simplify the
generate-changelog.sh
script by using the built-in sections feature of towncrier, instead of generating the changelog for each section separately.This is the result, which should be the same as before:

We could almost get rid of the
header.md
file except we cannot format the release date.Preview: https://pr1598--matrix-spec-previews.netlify.app
