Karanbir Singh has announced the availability of the first point update to CentOS 7, a Linux distribution built by compiling the source code of Red Hat Enterprise Linux 7: "We would like to announce the general availability of CentOS Linux 7 (1503) for 64-bit x86-compatible machines. This is the second major release for CentOS 7 and is tagged as 1503. This build is derived from Red Hat Enterprise Linux 7.1. This merges in all base, updates, and CR (continuous release) components released in the month of March 2015. If you have been using the CR repositories on your previous CentOS Linux 7 install, you already have all the components used to compose this new release. This release supersedes all previously released content for CentOS Linux 7, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the release notes."
