X Server 1.5.1 Has Been Released
Red Hat's Adam Jackson has just announced the X Server 1.5.1 release on the X.Org mailing list. This point release just includes conditionalizing Composite-based backing store on pScreen->backingStoreSupport (compliments of NVIDIA), moving RELEASE_DATE below AC_INIT, disabling shared pixmaps for EXA, and fixing panoramiX request and reply swapping.
The source-code can be downloaded immediately and expect this to be quickly adopted by Linux distributions that are already tracking X Server 1.5 / X.Org 7.4. With this fixer-up release now out there, hopefully X.Org 7.4 will make it out before the end of the month.
