CastHub follows Semantic Versioning to deliver your content to Users through initial downloads and updates.
You can create a new Version via the in-app Developers section. Through this, you can also target a specific version of the CastHub App, such as a future release which has a breaking API change or new feature you're targeting. You can find the Developers section by clicking your avatar in the titlebar of the App.
Drafting new Versions is only available after your initial v1.0.0 Version release.
