We record noteworthy changes in this file, which then becomes http://jenkins-ci.org/changelog
- Record your changes between "TRUNK-BEGIN" and "TRUNK-END".
  (except in rare cases when you are making changes in the RC branch,
   in which case it goes to the rc section)
- There are four CSS classes to denote the kind of changes.
  "rfe" for enhancement and "bug" for bug fixes,
  plus "major" to indicate major RFE/bugfix.
- Link to bugs in the issue tracker, e-mail thread in the archive, and so on if you can.
