 * Fixed an issue whereby board revision ``0`` did not include overlay files for that revision.
 
+* Added ``PRE_IMAGE_CMAKE`` and ``POST_IMAGE_CMAKE`` hooks to sysbuild modules, which allows for
+  modules to run code after and before each image's cmake invocation.
+
+* Added :kconfig:option:`CONFIG_ROM_END_OFFSET` option which allows reducing the size of an image,
+  this is intended for use with firmware signing scripts which add additional data to the end of
+  images outside of the build itself.
+
+* Added MCUboot image size reduction to sysbuild images which include MCUboot which prevents
+  issues with building firmware images that are too large for MCUboot to swap.
