+   shared across images to reduce memory footprint. The romlib image is stored
+   in ROM but is accessed through a jump-table that may be stored
    in read-write memory, allowing for the library code to be patched.
 
+-  A prototype implementation of a Secure Partition Manager (SPM) that is based
+   on the SPCI and SPRT specifications.
+
+-  Support for ARMv8.3 pointer authentication in the normal and secure worlds.
+   The use of pointer authentication in the normal world is enabled whenever
+   architectural support is available, without the need for additional build
+   flags. Use of pointer authentication in the secure world remains an
+   experimental configuration at this time and requires the ``ENABLE_PAUTH``
+   build flag to be set.
+
+-  Position-Independent Executable (PIE) support. Initially for BL31 only, with
+   further support to be added in a future release.
