I am pleased to announce a new version of cx_Oracle, a Python DB-API 2.0
compliant interface module. The changes are as follows....

Changes from 2.1 to 2.2

 1) Upgraded thread safety to level 1 (according to the Python DB API 2.0)
as
    an internal project required the ability to share the module between
    threads.
 2) Added ability to bind ref cursors to PL/SQL blocks as requested by
    Brad Powell.
 3) Added function write(Value, [Offset]) to LOB variables as requested by
    Matthias Kirst.
 4) Procedure execute() on Cursor objects now permits a value None for the
    statement which means that the previously prepared statement will be
    executed and any input sizes set earlier will be retained. This was done
to
    improve the performance of scripts that execute one statement many
times.
 5) Modified module global constants BINARY and DATETIME to point to the
    external representations of those types so that the expression
    type(var) == cx_Oracle.DATETIME will work as expected.
 6) Added global constant version to provide means of determining the
current
    version of the module.
 7) Modified error checking routine to distinguish between an Oracle error
and
    invalid handles.
 8) Added error checking to avoid setting the value of a bind variable to a
    value that it cannot support and raised an exception to indicate this
fact.
 9) Added extra compile arguments for the AIX platform as suggested by
Jehwan
    Ryu.
10) Added section to the README to indicate the method for a binary
    installation as suggested by Steve Holden.
11) Added simple usage example as requested by many people.
12) Added HISTORY file to the distribution.

If there are any comments please feel free to write to me at
anthony@computronix.com. Thanks.
