Scientific Linux 6.5 is a distribution built from source package for Red Hat Enterprise Linux 6.5 with extra software designed for use in scientific and academic environments. The SL6x repository has been updated to SL6.5 at this time. Users of the Scientific Linux 6x repository should run 'yum clean expire-cache'. This should allow yum to notice the updated metadata within the 6x repository. Major differences from Scientific Linux 6.4: OpenAFS has been updated to version 1.6.5.1 from openafs.org - this package may have some issues, please note there is a possibility for system panic under certain conditions; alpine 2.10 - updated to more recent version (from Fedora); yum-autoupdate-2 6.3 - bug fixes for extra, useless reporting, remove the obsolete augeas lense.

About Scientific Linux
Scientific Linux is a recompiled Red Hat Enterprise Linux, co-developed by Fermi National Accelerator Laboratory and the European Organization for Nuclear Research (CERN).
