   * enhancement: MAP-ALLOCATED-OBJECTS (the heart of ROOM) now walks the
     heap in a manner similar to the GC rather than its previous ad-hoc
     scheme, and is therefore no less and possibly more accurate.
+  * fixes and enhancements related to Unicode:
+    ** the character database information has been updated to Unicode 6.2;
+    ** support for canonical and compatibility decomposition of characters has
+       been added, along with support for primary composition;
+    ** support for Unicode normalization forms of strings (NFC, NFKC, NFD and
+       NFKD) has been included;
+    ** querying the character database for code points not defined by Unicode
+       gives less wrong answers (lp#1178038, reported by Ken Harris)
   * bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
     of quadratically with the size of the input in the worst case.
