Roller 0.9.7.2 is available.
This is a minor bug fix release, see JIRA for the fix list. The release is available on SourceForge or you can get it via CVS from the ROLLER_0972 tag.
The most significant fix is that all URLs generated by Roller are once again relative (as they were in earlier versions). Also, a new setting has been added to the Website:Config page to allow you to configure the base URL for those URLs that cannot be relative (those in RSS feeds, XML-RPC return values, Trackbacks, etc.). These changes make it easier to run Roller behind an HTTPS configured web server.
The out-of-memory problems reported by users have turned out to be the results of misconfigured JVM, Tomcat, and OSCache settings, so I think Roller 0.9.7.2 is ready for deployment on FreeRoller.
UPDATE 3:02PM EST: If you have already downloaded the build, please download it again. I found a little glitch and had to do a respin.
