7.3 CR1 is now available for download. From last release of 7.3 Beta1, support for auto-increment IDs for temp tables is added. Also couple caching issues has been resolved when the JBoss AS being run in the "all" profile. When using H2 as the source "boolean" data type was being imported incorrectly, that has been fixed along with few other issues. For more information check out the JIRA issues here.
If you have been putting off 7.3 version so far and working with 7.2-Final, this is time for you to check your usecase with 7.3 version and report any regressions that we might have missed, so that we can fix them before the 7.3 Final is released.
