- Please welcome Xorg 7.5.2

       The Xorg Team is pleased to announce the next round of Xorg updates.
       The team created a new flag called WITH_NEW_XORG that users can include
       in /etc/make.conf. This was created for the intel KMS work being done
       althouthough It probably works for other chips. Unfortunately, the intel
       KMS driver will only work on FreeBSD 9(RELENG|STABLE) or 10/HEAD users.
       Older version of FreeBSD will not be supported. Intel users will need
       to patch their source manually with Konstantin?s KMS kernel patch to get
       the newer chips to work. Please carefully read UPDATING entry.

Changes:

        - libdrm 2.4.31 (including KMS support)
        - mesa 7.11.2
        - xorg-server 1.10.6
        - a lot of new Graphic Drivers.

    I would like to thank:

         Eitan Adler
         Niclas Zeising
         and all helpers and testers from x11@.
