Changelog generator fixes

There were several problems that this fixes:
- shallow fetch broke merging to release branch
- bad changelog was only outputting error msg (not exiting)
- latest version being on first line deleted itself and broke the
  changelog updates

This also has manual fixes to the changelog to bring it up to date.
