+      This version is 100% backwards compatible with STIR 6.1, aside from a bug fix for
+      the blocks-on-cylindrical set-up which caused the wrong geometry, and a changed

 <h2>Overall summary</h2>
     <p>
-
+      Main new features are the capability to mash TOF bins (via <tt>SSRB</tt> utility/code)
+      and a CUDA version of the Relative Difference Prior. There are also some
+      import bug fixes, as well as some speed-up (hopefully) in the use of arrays.
