Useful when the change log is to be included in a native package or in a WAR as documentation.
Instead of making a plain text version for the changes-report goal, I opted to make the announcement-generate goal more configurable. That way you can also include issues from JIRA.
Fixed in r1054308.
New 2.4-SNAPSHOT deployed for those who want to test drive this. See the example in the docs on how to use it.
Or use antrun to copy it to suitable location.
You can also create your own velocity template if you want to change the layout or content, but the default announcement.vm file produced by "mvn changes:announcement-generate" is pretty good as is.
What you cannot change currently is the output file name (same as template name) or directory (target/announcement).
Just rename the file and move it somewhere suitable.
You can probably use the announcement:generate goal for this.
