RELEASING.md

0. Consider whether this release will affect any customers, including those on EMS, and warn them beforehand - in case they need to upgrade quickly.

1. Set a variable to the version number for convenience:

   ver=x.y.z

2. Update the changelog:

   towncrier --version=$ver

3. Push your changes:

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

4. Sanity-check the changelog and update if need be.

5. Create a signed tag for the relese:

   git tag -s v$ver

   Base the tag message on the changelog.

6. 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.

7. Create release on GH project page:

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

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