No, it’s not released, but Martin Wilke is looking for a few brave people to test x.org 7.5 for FreeBSD:
Please take a look on our Wikipage. There you can find the svn repo to checkout X.org ports.
A small merge script to merge the svn checkout into the real portstree could be found here:
The script is a modified version of the kdemerge script. Please set the KDEDIR variable to the path of your X.org
After merging please try
portupgrade -af \*
Please report any problems and issus to x11 (at) FreeBSD.org.
