It has already been binnmued on all the official ports but the subject of the mail said [armhf] which is currently on debian-ports.org. Of the three ports on debian-ports.org that have built the current version of the package (including armhf none appear to have been either binnmu'd or otherwise built since kibi's block post.xserver-xorg needs a binNMU, you can find the details in this blog post: http://blog.mraw.org/2011/06/14/mesa_a_disturbance_in_the_Force/It already has been. http://buildd.debian.org/xorg-server
http://buildd.debian-ports.org/status/package.php?p=xorg-server
There's no need to email port mailing lists to request binNMUs, these are scheduled centrally by the wanna-build admins.
Is there such a central authority for ports on debian-ports.org or only for the architectures in the official archive?
