CentOS announce - Jan 2015 - Improvements in the docker registry for CentOS

The CentOS images in the docker index have been bumped to 20150102.
Additionally there are numbering scheme improvements requested by the
community.

Fixes
====1. All updates through 20150101 applied to rolling builds


Enhancements
===========1. Minor version tags - 5.11, 6.6, and 7.0.1406
   These builds are built from install media only. They do not contain
updates and will not be updated as part of the rolling/monthly builds.
They are meant for use by those with specific vendor versioning
requirements. Users are responsible for ensuring that the images are
updated as needed via a 'yum update -y' in their Dockerfiles or other
method.

2. Short names
   Users can now use short names to identify specific docker image tags.
For example: centos:6 in place of centos:centos6. Both names are now
valid and point to the same images.


Additional Information

used in
