Since we are back on track churning out JBoss AS releases, here is another one: JBoss Application Server 4.2.3.GA. You can start downloading it immediately from here.
This is the 3rd bug fixing release of the JBoss Application Server v4.2 series. It provides more than 80 bug fixes thanks to your valuable input. There were also some backwards compatible component upgrades so switching to AS 4.2.3.GA from a previous 4.2.0/4.2.1/4.2.2 release should not present any problems.
A secondary target for this release was to improve support for Java 6. JBossAS 4.2.3.GA can be build with both JDK5 and JDK6. The JDK5 compiled binaries have undergone more rigorous testing, they constitute our certified version and can run under both Java 5 & 6 VMs (with a few configuration changes for JDK6). The JDK6 compiled binaries include support for the JDBC 4 APIs, but this should be considered experimental at this point.
Please check out the Detailed Release Notes for the full details.
