If there was a change in the upstream repository ([isaul32/ckeditor5-math](https://github.com/isaul32/ckeditor5-math)), it can be integrated as follows:
1. Add the upstream as remote (`git remote add upstream ssh://git@github.com/isaul32/ckeditor5-math.git`).
2. Fetch the changes: `git fetch upstream`
3. Merge with a tag: `git merge v43.1.2`
4. Solve the conflict in `package.json` by:
1. Taking the same version as the upcoming one and appending `-hotfix1`.
2. Keeping the `@triliumnext/ckeditor5-math` name.
5. Install dependencies: `yarn install`
6. Check that the build works via `yarn prepublishOnly`.
7. Commit the changes, push them.
8. Release a version with<a class="reference-link" href="Release%20management%20%26%20continuou.md">Release management & continuous integration</a>.
