We've recently upgraded from Hudson 1.375 to 1.377. It appears that the RSS feeds for build (e.g. rssLatest) has changed subtlely

The feed appears to no longer have SUCCES/FAILURE/UNSTABLE in the ( ) after the build name.
In our system, these codes are lower case now and feature previously unseen states. e.g. "stable" rather than "SUCCESS".

This may not be a bug, of course. Just raising this issue to confirm that this behaviour change was expected.
