+            Each Yocto Project release introduces a new set of linux-yocto
+            kernel recipes that tracks the latest upstream developments and
+            introduces newly supported platforms.
+            In addition to the new kernel recipes, the previous recipes are
+            refreshed and supported for at least one additional release.
+            As they align, these previous releases are updated to include the
+            latest from the Long Term Support Initiative (LTSI) project.
+            Besides these recipes, a <filename>linux-yocto-dev.bb</filename>
+            recipe is available for working with the very latest in upstream
