+
+       - Some more cleanups in the library.
+
+ Thu May  7 12:34:28 CEST 1998
+
+       - Made CONNECT and DISCONNECT statement more SQL3 compliant.
+       - Changed the API for the ECPGconnect function to be able to handle
+         hostnames and ports
+
+ Fri May  8 13:54:45 CEST 1998
+       - More changes to the parser. The connect statement now allows
+         ORACLE style logins.
+       - db-name is accepted in two ways:
+               - <dbname>[@<server>][:<port>]
+               - esql:postgresql://<server>[:<port>][/<dbname>]
+
+ Mon May 11 10:28:37 CEST 1998
+
+       - Added '? options' to connect call.
+       - Also allow USING as keyword for the password
+
+ Thu May 14 15:09:58 CEST 1998
+
+       - Changed preproc.y and pgc.l according to the parser changes in the
+         backend.
+
+ Fri May 15 09:55:21 CEST 1998
+
+       - Added connection_name handling
+
+
+ Mon May 18 10:33:58 CEST 1998
+
+       - Fixed some more bugs
+       - Set version to 2.3.1
+       - Set library version to 2.2
