+
+  This release addresses a quite annoying bug that could occur when saving
+  reviewer assignments, and widens the short floor indication string that
+  is shown on the agenda from 2 to 3 characters.
+
+  * Rewrote the head-of-rotation review assignment loop to guarantee that 
+    it will terminate.  This should fix the 'gateway timeout' issues we've seen 
+    lately, when review request volume in some review teams have been such that 
+    multiple assignments to the head of queue members have triggered the issue.
+
+  * Changed the floorplan short string from 2 to 3 characters, in order to 
+    support things like London Hilton Metropole's level -3E, 3rd lower ground 
+    floor East.
+
+  * Changed the arguments to the xml2rfc parser to use normalize=True, in
+    alignment with xml2rfc internal use.
