Correlate svn/trac changest number with hudson build number

I have a software build that has an internal number from our hudson number. I'm trying to figure out if feature X was included in that build. I know what svn (also shows up in trac if there's a way to do it through trac) changeset this change occurred in. I only store a couple of weeks worth of builds i开发者_开发知识库n hudson, so I can't just lookup the build in hudson. Is there a way to determine what changesets were included in which build numbers?

We use hudson with subversion and part of the build process is to automatically add the subversion branch and global revision details to the distribution. Not sure if Hudson can pick these up and have it appear as some kind of custom field in the web interface.
