340b76b42cReported by formerly Old_Demon on blenderartists. Apparently this caused old files to lose their links to material sockets (noob own mistake from inexperience with node system). This should either be included in release with version checking being set to version 2.73 and subversion 10, without tweaking the BKE_blender.h file OR340b76b42cshould be reverted for this release. Thanks to Lukas for checking this out.
