Last thing to do is publish a version tag with git.. Make sure the webhook to packagist is working on your github repository.
You can do this using:
git tag 0.1.0-beta.4
git push origin master --tags
You can pick whatever version you want ofcourse. The beta prefix denotes it's beta. I personally already publish stable releases, other devs are not doing so, most likely due to the beta state of flarum.
