+* Mon Jul  4 2011 Paul Howarth <paul@city-fan.org> 3.3.23-1
+- update to 3.3.23
+  - fixed ItemFactory callbacks as their argument lists did not reflect the
+    correct callback argument type/order for callback_type=1; this is a
+    long-standing hidden bug that would prevent pattern search from working on
+    64-bit big-endian architectures
+  - fixed broken "replace" signal option
+
 * Sat Jun  4 2011 Paul Howarth <paul@city-fan.org> 3.3.22-1
 - update to 3.3.22
   - optimized tree build so it can handle large amounts of component
