+What's new in psycopg 1.99.12
+-----------------------------
+
+* .rowcount should be ok and in sync with psycopg 1.
+
+* Strings can contain NULLs and are quoted accordingly.
+
+* Implemented the new COPY FROM/COPY TO code when connection to the
+  backend using libpq protocol 3 (this also removes all asprintf calls:
+  build on win32 works again.) A protocol 3-enabled psycopg *can*
+  connect to an old protocol 2 database and will detect it and use the
+  right code.

+ psycopg 2 is the next generation psycopg, implementing a much better
+ type system and even more DBAPI extensions:
+ .
+ * support for Python datetime and Decimal types;
+ * complete implementation of adapt() from PEP 246 to convert Python
+   types to PostgreSQL ones;
+ * COPY FROM/COPY TO support
+ * inehritable connection and cursor objects and support for connection
