Consider whether this release will affect any customers, including those on EMS, and warn them beforehand - in case they need to upgrade quickly.
Update the version number in pyproject.toml.
Set a variable to the version number for convenience:
```
ver=x.y.z
```
Update the changelog:
```
towncrier --version=$ver
```

Push your changes:

git add -u && git commit -m $ver && git push

Sanity-check the changelog and update if need be.
Create a signed tag for the relese:
```
git tag -s v$ver
```
Base the tag message on the changelog.
Push the tag:
```
git push origin tag v$ver
```
Pushing a tag on GitHub will automatically trigger a build in Docker Hub and the resulting image will be published using the same tag as git.

Create release on GH project page:

xdg-open https://github.com/matrix-org/sygnal/releases/edit/v$ver

Notify #sygnal:matrix.org, #synapse-dev:matrix.org and EMS that a new release has been published.
