Releasing a new version of DeltaChat core
For example, to release version 1.116.0 of the core, do the following steps.
1. Resolve all [blocker issues](https://github.com/deltachat/deltachat-core-rust/labels/blocker).
2. Update the changelog: `git cliff --unreleased --tag 1.116.0 --prepend CHANGELOG.md` or `git cliff -u -t 1.116.0 -p CHANGELOG.md`.
3. add a link to compare previous with current version to the end of CHANGELOG.md:
`[1.116.0]: https://github.com/deltachat/deltachat-core-rust/compare/v1.115.2...v1.116.0`
4. Update the version by running `scripts/set_core_version.py 1.116.0`.
5. Commit the changes as `chore(release): prepare for 1.116.0`.
Optionally, use a separate branch like `prep-1.116.0` for this commit and open a PR for review.
6. Tag the release: `git tag --annotate v1.116.0`.
7. Push the release tag: `git push origin v1.116.0`.
8. Create a GitHub release: `gh release create v1.116.0 --notes ''`.
