  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
