I like the fix/improvement of the aforementioned issue, but there also seems to be a "Summary" section in old/classic UI's "Changes" section, that I think should also be adapted like this (if possible):

• see
• see "src/main/resources/hudson/scm/SubversionChangeLogSet/index.jelly", line 33

ljader added the following comment:

I've ran an initial analysis and I think parsing commit message should be implemented as in Git Plugin.
The git-plugin checks if there is a blank 2nd line (commit message with format http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html) and displays only this line on main job page and each build page,
but it displays full commit message on "Changes" section (job/test-git-repo/4/changes).

Just for reference, please checkout usage of "msgAnnotated" and "commentAnnotated" here:
