CentOS is an Enterprise class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor.
CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.)
This OS is developed by a small but growing team of core developers. In turn the core developers are supported by an active user community including system and network administrators, enterprise users, managers, core Linux contributors and enthusiasts from around the world.
CentOS is a community-supported, mainly free software operating system based on Red Hat Enterprise Linux (RHEL). It stands for Community ENTerprise Operating System.
The developers use Red Hat’s source code to create a final product very similar to Red Hat Enterprise Linux. CentOS is free.
CentOS has numerous advantages over some of the other clone projects including: an active and growing user community, quickly rebuilt, tested, and QA’ed errata packages, an extensive mirror network, developers who are contactable and responsive, multiple free support avenues including IRC Chat, Mailing Lists, Forums, a dynamic FAQ.
CentOS 7 (1708) most notable changes are:
Since release 1503 (abrt>= 2.1.11-19.el7.centos.0.1) CentOS-7 can report bugs directly to bugs.centos.org. You can find information about that feature at this page.
- Various new packages include among others: python-gssapi, python-netifaces, mod_auth_openidc, pidgin and Qt5.
SSH1-support has been removed from the SSH-server. Along with this move, all cryptographic protocols and algorithms which are considered insecure have been deprecated. More on this can be found here and here.
- OpenSSL now supports DTLS (TLS via UDP) and ALPN.
- NVMe Over Fabric is now supported in the NVM-Express kernel driver.
- There have been various changes/enhancements to cryptographic abilities of various packages. I.e. sendmail now supports ECDHE, OpenSSH now using SHA2 for public key signatures, … among others. All changes are too numerous to mention here, so please take a look at the upstream release notes.
Various packages have been rebased. Some of those are openLDAP, samba, clufter, ipmitool, tcpdump, shim, GNOME, NetworkManager, Kernel-GRE-module, openssh, openSSL, libreswan, chrony, rsyslog, sudo and libvirt. Users of openldap should see the note in the known issues section below.
Because of these rebases some 3rd party repositories (Like EPEL, ELRepo, nux!, etc.) may not have all their packages rebuilt to use the newer packages in this release. This may cause the inability to update to the new release until those repositories fix their dependencies. You should contact the 3rd party repository owner to get problems fixed, or remove problem packages from 3rd party repositories to complete the update to this release.
- SHA2 is now supported by OpenLDAP.
- ECC-support has been added to OPenJDK-8, PerlNet:SSLeay and PerlIO::Socket::SSL.
- Bluetooth LE is now supported.
- virt-p2v is now fully supported. virt-v2v and virt-p2v add support for the latest windows releases.
- Lots of updated storage, network and graphics drivers.
- Technology Preview: Among others support of Btrfs, OverlayFS, CephFS, DNSSEC, kpatch, the Cisco VIC and usNIC kernel driver, nested virtualization with KVM and multi-threaded xz compression with rpm-builds.
There are some important changes to this release compared with the previous versions and highly recommended reading this announcement along with the Release Notes.
