+Announce: Release of PyGreSQL version 3.1
 ===============================================
 
-PyGreSQL v3.0 has been released.
+PyGreSQL v3.1 has been released.
 It is available at: ftp://ftp.druid.net/pub/distrib/PyGreSQL.tgz.  If
 you are running NetBSD, look in the packages directory under databases.
 There is also a package in the FreeBSD ports collection.              
@@ -25,16 +25,11 @@ PyGreSQL is a python module that interfaces to a PostgreSQL database. It
 embeds the PostgreSQL query library to allow easy use of the powerful
 PostgreSQL features from a Python script.
 
-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.
+This release fixes a few bugs, adds a few minor features and makes a
+few speedups in the code.
 
-Due to the fact that the DB-API is brand new, it is expected that there
-will be a 3.1 release shortly with corrections once many people have
-had a chance to test it.
+The next release (unless serious bugs are found) will be to match PyGreSQL
+to version 2.0 of Python.
 
 See the other changes below or in the Changelog file.

 the code to use full ANSI style prototypes and changed the order of
