- Made sure SET DESCRIPTOR accepts all data types including constants.
+ - Some code cleanup.
+
+Mon, 5 Jul 2004 10:41:54 +0200
+
+ - Fixed indicator in SET DESCRIPTOR.
+ - Added special handling of descriptor header information.
+ - More code cleanup.
- Set pgtypes library version to 1.2.
- Set ecpg version to 3.2.0.
- Set compat library version to 1.2.
