+0.9.3, Apr 2006
+
+  Backward incompatible library changes:
+    * The NC.Hashtable indexer was changed to follow SCG.Dictionary behavior
+      of throwing exception when the key is not found.
+
 0.9.2, Jan 21 2006
   This version brings a bunch of new features and of course several bugfixes.
   We now require mono 1.1.11+ or MS.NET 2.0.
