Squiz Matrix Operating System Support Statement
Each minor release of Squiz Matrix is supported on the major version of the Operating System (OS) it was originally released on until either the OS vendor ceases support for the OS or 36 months elapse since that Minor release of Squiz Matrix was released.
For most OSs', security and maintenance fix updates are only provided for the latest minor version of that OS, so users will need to update their OS installation to the latest minor version of the OS to continue receiving security and maintenance fixes for the entirety of the supported period.
Squiz Matrix updates may also require packages additional to those provided by the OS and these will be indicated in the release notes for each version of Squiz Matrix.
For example, Squiz Matrix 5.3 was released in November 2015 and is fully supported until November 2018. At release, it was tested and certified on Red Hat Enterprise Linux version 6, which is supported by Red Hat until November 30, 2020.
This means users could have built a server with Squiz Matrix 5.3 and Red Hat Enterprise Linux 6 in November 2016, and retain that server as a fully supported configuration simply by applying OS package and Squiz Matrix updates until November 2018.
