We would like to announce the general availability of CentOS Linux 7 for 64 bit x86 compatible machines. This is the first release for CentOS-7 and is version marked as 7.0-1406.
Since the upstream EL7 release, there have been some updates released – – these have been built and are being pushed to the CentOS mirror network at the moment. They will be available within the next 24 hrs. – From this point on we will aim to deliver all updates within 24 to 48 hrs of upstream releases.
For the first time, this release was built from sources hosted at git.centos.org, however srpms being a byproduct of the build and also considered critical in the code and buildsys process are being published to match every rpm we release. Sources will be available from vault.centos.org in their own dedicated directories to match the corrosponding binary rpms.
For the CentOS-7 build and release process we adopted a very open process. The output of the entire buildsystem is made available, as its built, at http://buildlogs.centos.org/ – we hope to continue with that process for the life of CentOS-7, and attempt bringing CentOS-5 and CentOS-6 builds into the same system.
CentOS 7.0-1406 introduces a new numbering scheme that we want to further develop into the life of CentOS-7. The 0 component maps to the upstream realease, whose code this release is built from. The 1406 component indicates the monthstamp of the code included in the release ( in this case, June 2014 ). By using a monthstamp we are able to respin and reissue updated media for things like container and cloud images, that are regularly refreshed, while still retaining a connection to the base distro version. In order to facilitate Special Interest Groups to further extend the CentOS Linux platform, we are also using component codes. The main distro is, therefore, titled ‘Core’. SIGs would be able to adopt any name they need and deliver that by overriding the base centos-release rpm.
