CentOS is een opensource-besturingssysteem dat gebaseerd is op Red Hat Enterprise Linux en zich profileert voor gebruik in enterprise-omgevingen. De naam is een afkorting van Community Enterprise Operating System. In tegenstelling tot RHEL is CentOS gratis te gebruiken. Als naar populariteit gekeken wordt, valt CentOS net binnen de top tien. Elke twee jaar verschijnt er een nieuwe versie van CentOS, die vervolgens zeven jaar lang van updates wordt voorzien. Versie 7 (1611) van CentOS is nu uitgebracht en de volledige releasenotes zijn hier te vinden. Dit zijn in het kort de belangrijkste veranderingen:
Major Changes
- 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.
- Support for the 7th-generation Core i3, i5, and i7 Intel processors and I2C on 6th-generation Core Processors has been added.

Note: 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.
