Rolling builds for CentOS Linux are now available. CentOS Linux rolling builds are point in time snapshot media rebuild from original release time, to include all updates pushed to
mirror.centos.org's repositories.



Here the announcement:

I am pleased to announce general availability of the rolling builds
for CentOS Linux. Todays release includes CentOS Linux 7 iso based
install media and the generic cloud images.

CentOS Linux rolling builds are point in time snapshot media rebuild
from original release time, to include all updates pushed to
mirror.centos.org's repositories. This includes all security, bugfix,
enhancement and general updates for CentOS Linux. Machines installed
from this media will have all these updates pre-included and will look
no different when compared with machines installed with older media
that have been yum updated to the same point in time. All rpm/yum
repos remain on mirror.centos.org with no changes in either layout or
content.

We will aim to update and issue for release a new set of these files
at the end of every month going forward. Each released filename
includes a datestamp and a buildtag to indicate the content included.
Files marked as 20141129_02 indicate that it includes all content
released to mirror.centos.org upto ( and including ) the 29th of Nov
2014 and is the second build of that cycle. While all build's are made
public at buildlogs.centos.org/, only those that pass our QA and
testing cycles will be marked as released, to be included in
buildlogs.centos.org/rolling/. We will also do interim builds as
needed ( for development and testing purposes ) at different points in
time, those builds will not be marked for general release, but will
still be avilable publicly.

Since there is a need to test these images, the release will always
lag few days behind the datestamp ( and therefore content included )
in the release. My aim is to automate as much of this as possible
going forward to reduce this time lag as much as possible, however we
might not be able to remove it completely.

With every cycle, we hope to increase the content made available in
this rolling format. Immediate next steps include bringing the CentOS
Linux 7 livemedia into the rolling releases followed by CentOS Linux 6
content from the next ( December 2014 ) cycle.

Due to the way the installer works in CentOS-5, and its point in time
we have no plans on including CentOS-5 in this cycle at this point.

For the sake of uniformity and communication, the release media will
be referenced by the month it reflects, not the month it was released
in. Making this release the Nov 2014 Rolling release.

Other content formats like containers and vendor specific images will
aim to start with the same cycle as the main CentOS Linux media, but
might move to a more frequent build and release cycle if needed.
Special Interest Groups ( http://wiki.centos.org/SpecialInterestGroup
) wanting to do media and installer releases should also consider
using the rolling timelines to sync with.

Finally, I want to highlight that we will always consider doing a
rolling release to address major security issues like the recent
heartbleed, shellshock and poodle patches.
