-there were enough fixes that I didn't want to keep them from a release.
+This release of PyGreSQL is the first DB-SIG API.  That's why we have
+a bump in the major number.  There is also a potential problem in
+backwards compatibility.  Previously when there was a NULL in a returned
+field it was returned as a blank.  Now it is more properly returned as
+a Python None.  Any scripts that expect NULLs to be blanks will have
+problems with this.

+PyGreSQL 2.0 was developed and tested on a NetBSD 1.3_BETA system.  It
 is based on the PyGres95 code written by Pascal Andre,
 andre@chimay.via.ecp.fr.  I changed the version to 2.0 and updated the
 code for Python 1.5 and PostgreSQL 6.2.1.  While I was at it I upgraded
 the code to use full ANSI style prototypes and changed the order of
 arguments to connect.  Later versions are fixes and enhancements to that.
+The latest version of PyGreSQL works with Python 1.5.2 and PostgreSQL 6.5.
+

+  - Remove strlen() call from pglarge_write() and get size from object.
