Pat Riehecky has announced the release of Scientific Linux 6.6, the latest update of the distribution built from source package for Red Hat Enterprise Linux 6.6, with additional software meant for use in scientific and academic environments: "Scientific Linux 6.6 i386/x86_64. Major differences from SL6.5: OpenAFS has been updated to version 1.6.10 from openafs.org; X.Org Server features a new ABI. Users of proprietary drivers may experience issues with the X server loading due to changes between X.Org Server 1.13 and 1.15. Users of the 32-bit iSCSI utilities on x86_64 systems may experience multilib complaints. The 32-bit iSCSI utilities are not provided by upstream on x86_64 platforms. We have removed them from 6.6 to follow their behavior."
