We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Releasing 1.0
With #2435 rounding out the final thing I think we need for the next release, I think it's time to put together the 1.0 release.

This should consist of:

- [x] assembling changelog #2440
- [x] making sure new features are well documented
- [x] publishing beta release
- [x] test beta (perhaps by adding it to the z2jh chart)
- [ ] release 1.0 final

--- END ISSUE ---
