Yesterday, 8th Aug., Connie Sieh announced the release of Scientific Linux 6.3, an enterprise-class distribution built from source package for Red Hat Enterprise Linux 6.3: "Scientific Linux 6.3 i386/x86_64 is now available.
Last week, I reviewed the beta1 version. Simply outstanding distro, especially meant for power users. Further, it is feature packed and offers a wide range of applications as well as enterprise level stability. Added benefit of installing Scientific Linux is that it has full support till Q2 2017 and maintenance support till Nov-2020!
I already installed beta1 version last week. Once the final release came, I just updated my existing installation.
Rest here
