Red Hat has announced it is retiring support for Red Hat Enterprise Linux 5. Version 5 was originally released back in 2007 and, following ten years of support and eleven updates, is being retired. This will also likely mark the end of support for related community projects such as CentOS 5. Red Hat customers who need to continue using version 5 have the option of purchasing extended support for three and a half years. The Red Hat announcement has further details: "We recognize that some customers will wish to remain on Red Hat Enterprise Linux 5 even after the March 31, 2017 retirement date. To meet this customer requirement, Red Hat will offer customers the option to purchase the Extended Life Cycle Support (ELS) Add-On as an annually renewable subscription. This ELS Add-On provides customers with up to an additional three and a half (3.5) years of Critical Impact security fixes and selected Urgent Priority bug fixes for Red Hat Enterprise Linux 5.11. Red Hat Enterprise Linux 5 ELS coverage will conclude on November 30, 2020. Note that the Red Hat Enterprise Linux 5 ELS Add-On is available for the x86 (32- and 64-bit) and z Systems architectures only. The Red Hat Enterprise Linux 5 ELS Add-On is not available for the Itanium architecture. In addition, the Red Hat Enterprise Linux 5 ELS Add-On is only available for Server, and does not apply to layered products or Add-Ons."
