- there are a few typos, mostly lower/upper case letter ones
- use Fedora 18 instead of f18, especially in Release Notes
- provide more info for Contingency Plan/How To Test to include the metrics of the issues, the detailed how to test - with hints to recognize autohinting issues, also I'd pick a few prominent apps in different toolkits as a part of test coverage
- the autohinting fix how-to should be moved from Release Notes to Detailed Description section as I'm not sure it should be a part of end-users Release Notes
See my email, thank you, Jaroslav.
