[xwiki-devs] Building the source for XWiki Enterprise 1.3

Hi all, I downloaded XWiki Enterprise 1.3 RC1 some weeks ago and brought it to run with MySql 4 and Tomcat 5.0.28. Now, I want to do the same for the new version 1.3, but I want to build this version from source. Is there a way to get the complete source of version 1.3? (For Building - and especially for my understanding) And how can I compare the differences of the source code of two released versions (e.g. XWiki Enterprise 1.2 and 1.3), so that I can review the consequences of changing a release in the future? Thanks a lot and best Regards, Marco P.S. I'm new to this list. Please apologize, if this question is asked before.
