I am pleased to announce the general availability of CentOS Linux 7
(1708) for 64 bit x86 compatible machines. Effectively immediately, this
is the current release for CentOS Linux 7 and is tagged as 1708, derived
from Red Hat Enterprise Linux 7.4

As always, read through the Release Notes at :
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 - these notes
contain important information about the release and details about some
of the content inside the release from the CentOS QA team. These notes
are updated constantly to include issues and incorporate feedback from
the users.

Updates, Sources, and DebugInfos

Updates released since we froze the iso and install media content are
posted in the updates repo along with the release. This will include
content from late Aug 2017 and Sept 2017, therefore anyone
running a new install is highly encouraged to run a 'yum update'
operation immediate on install completion.  You can apply all updates,
including the content released today, on your existing CentOS Linux
7/x86_64 machine by just running 'yum update'.

As with all CentOS Linux 7 components, this release was built from
sources hosted at git.centos.org. In addition, SRPMs that are a
byproduct of the build (and also considered critical in the code and
buildsys process) are being published to match every binary RPM we
release. Sources will be available from vault.centos.org in their own
dedicated directories to match the corresponding binary RPMs. Since
there is far less traffic to the CentOS source RPMs compared with the
binary RPMs, we are not putting this content on the main mirror
network. If users wish to mirror this content they can do so using the
reposync command available in the yum-utils package. All CentOS source
RPMs are signed with the same key used to sign their binary
counterparts. Developers and end users looking at inspecting and
contributing patches to the CentOS Linux distro will find the code
hosted at git.centos.org far simpler to work against. Details on how
to best consume those are documented along with a quick start at :

Debuginfo packages are also being signed and pushed. Yum configs
shipped in the new release file will have all the context required for
debuginfo to be available on every CentOS Linux install.

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.

Note that older content, obsoleted by newer versions of the same
applications are trim'd off from repos like Extras/ and Plus/ However
this time we have also extended this to the sIG content hosted at
mirror.centos.org, and some older End of Life content has been dropped.
Everything we ever release, is always available on the vault service for
people still looking for and have a real need for it.


In order to conserve donor bandwidth, and to make it possible to get
the mirror content sync'd out as soon as possible, we recommend using
torrents to get your initial installer images:

Details on the images are available on the mirrors at
http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt - that file
clearly highlights the difference in the images, and when one might be
more suitable than the others.

The sizes, sha256 sums for the ISO files:

 CentOS-7-x86_64-DVD-1708.iso ( 4.2G)

CentOS-7-x86_64-Everything-1708.iso ( 8.1G)

 CentOS-7-x86_64-LiveGNOME-1708.iso ( 1.2G)

CentOS-7-x86_64-LiveKDE-1708.iso ( 1.7G)

CentOS-7-x86_64-Minimal-1708.iso ( 792 M)

CentOS-7-x86_64-NetInstall-1708.iso ( 422 M)

Information for the torrent files and sums are available at

Additional Images

The container, Vagrant, Cloud and Atomic Host images are being prepared
and will be released in the next few days. Look for an announcement
posted to the centos-announce list for more information on availability
for these in the coming days.


We try and organise Dojos in various parts of the world as a one day
event, to bring together people who use CentOS and others who are keen
to learn about CentOS. The day's focus is on sharing technical
knowledge and success stories. It's also a great place to meet and
talk about upcoming technologies and learn how others are using them
on CentOS Linux.

The next Dojo coming up is on the 20th Oct hosted by CERN, in
Switzerland. Details for this are available on
https://indico.cern.ch/event/649159/ ( please note that you must
register ahead of time to attend )

Getting Help

The CentOS ecosystem is sustained by community driven help and
guidance. The best place to start for new users is at

We are also on social media, you can find the project:
on Twitter at  : http://twitter.com/CentOSProject
on Facebook at : https://www.facebook.com/groups/centosproject/
on LinkedIn at : https://www.linkedin.com/groups/22405

And you will find the core team and a majority of the contributors on
irc, on freenode.net in #centos ; talking about the finer points of
distribution engineering and platform enablement.


This release was made possible due to the hard work of many people,
foremost on that list are the Red Hat Engineers for producing a great
distribution and the CentOS QA team, without them CentOS Linux would
look very different. Many of the team went further and beyond
expectations to bring this release to you, and I would like to thank
everyone for their help.

We are also looking for people to get involved with the QA process in
CentOS, if you would like to join this please introduce yourself on
the centos-devel list
(http://lists.centos.org/mailman/listinfo/centos-devel ).

As some people would have noticed there is no i686 build for 1708 as yet
- we have run into a couple of build and dependency issues that could
use help. So if you are keen to get involved this is a great opportunity.

Finally, please join me in thanking the donors who all make this
possible for us.

Enjoy the fresh new release!
