Hi all. This is my first post and I don't know this is the right forum.. I would like to have information about difference between 4.0.5 version and 4.2.3, if 4.2.3 is totally compatible with 4.0.5 and what are the new features in 4.2.3 compared with 4.0.5. I've found this link: http://www.jboss.org/community/docs/DOC-10734 but the link 4.0.5 -> 4.2.0 Changelog http://jira.jboss.com/jira/secure/ConfigureReport.jspa?versions=12311408&... is not working. Thanks for your help. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4185123#...
