According to the magic decoder ring the team has now cut another Release Candidate : 3.1 RC2 is here! Get promoted build 41 from the usual page.
Starting with the first RC last week, every promoted build is really a Release Candidate. I've taken a shot at generating a query returning the bugs fixed in this RC (I'm still a JIRA newbie).
If you had installed RC1, you can use the update center to update to RC2, a simple
bin/pkg image-update will do. You can also start the Update Tool (
bin/updatetool) and update the GlassFish install image.
