+====== Choosing a version of FreeBSD – operating system branches, code quality, lifespans, and support ======
+Each //release// of FreeBSD is the end result of periodic special attention – release engineering – to a ''releng'' branch of the code for the OS.
+===== Support =====
+With the [[https://www.freebsd.org/security/#model|five-year support model]] that was established in 2015, two or more major versions may be supported at any one time. 2024 changes to the model are [[https://wiki.bsd.cafe/docs:freebsd:choose#further_reading|noted below]].
+Major versions 13 and 14 are supported.
+has:
+  * a long lifespan – the ''stable/13''  branch
+  * one supported release – **13.5-RELEASE**  on the ''releng/13.5''  branch.
+has:
+  * a longer lifespan – the ''stable/14''  branch
+  * two supported releases – **14.2-RELEASE**  and **14.3-RELEASE**  on the ''releng/14.2''  and ''releng/14.3''  branches.
+FreeBSD 14.3-RELEASE is recommended for new installations. All other supported versions of RELEASE are //legacy//.
+===== Visualising CURRENT (the main branch) and RELEASE (releng branches) =====
