please please please include change list with new releases

[Ari Halberstadt]

I have no idea what has been changed in each version. Does version X fix some
bug? What are the new features I can use? Anything cool and fun to play with?
The changes.txt file included with v1.2.0 only goes up to v1.1.16, which is
woefully out of date. Configuration management and bug tracking software can be
used to automatically generate complete release notes, or you could have your
engineers keep notes and include them with the distribution.
