+Supported kernel versions
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The OLDEST_KERNEL setting has been changed to 5.15 in this release, meaning that
+out the box, older kernels are not supported. There were two reasons for this.
+Firstly it allows glibc optimisations that improve the performance of the system
+by removing compatibility code and using modern kernel APIs exclusively. The second
+issue was this allows 64 bit time support even on 32 bit platforms and resolves Y2038
+issues.
+
+It is still possible to override this value and build for older kernels, this is just
+no longer the default supported configuration. This setting does not affect which
+kernel versions SDKs will run against and does not affect which versions of the kernel
+can be used to run builds.
