                  Remote Python Database Interface

                            Version 2.1.3

 mxODBC Connect is our commercially supported client-server product for
       connecting Python applications to relational databases
                 in a truly platform independent way.

This announcement is also available on our web-site for online reading:



The mxODBC Connect Database Interface for Python allows users to
easily connect Python applications to all major databases on the
market today in a highly portable, convenient and secure way.

Python Database Connectivity the Easy Way

Unlike our mxODBC Python extension, mxODBC Connect is designed as
client-server application, so you no longer need to find production
quality database drivers for all the platforms you target with your
Python application.

Instead, you use an easy to install royalty-free Python client library
which connects directly to the mxODBC Connect database server over the

This makes mxODBC Connect a great basis for writing cross-platform
multi-tier database applications and utilities in Python, especially
if you run applications that need to communicate with databases such
as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix,
Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many
more, that run on Windows or Linux machines.

Ideal for Database Driven Client Applications

By removing the need to install and configure ODBC drivers on the
client side and dealing with complicated network setups for each set
of drivers, mxODBC Connect greatly simplifies deployment of database
driven client applications, while at the same time making the network
communication between client and database server more efficient and
more secure.

For more information, please have a look at the mxODBC Connect product
page, in particular, the full list of available features.

mxODBC Connect 2.1.3 is a patch level release of our successful mxODBC
Connect database product. It includes these enhancements and fixes:

Security Enhancements

 * Updated included OpenSSL libraries to 1.0.1m. See
   https://www.openssl.org/news/secadv_20150319.txt for a complete
   list of changes. Among other security fixes, this addresses the
   FREAK Attack (CVE-2015-0204).

 * Upgraded default RSA key length for demo certificates to 2048 bits.

mxODBC Connect Enhancements

 * Upgraded eGenix PyRun used for mxODBC Connect Server on Linux to

 * Upgraded the Python version used for mxODBC Connect Server to

 * Fixed a bug causing pip uninstall not to remove .pyc/.pyo files

 * Resolved an intermittent error related to hash seeds which
   sometimes caused prebuilt archives to not install correctly. Thanks
   to Albert-Jan Roskam for reporting this.

mxODBC API Enhancements

 * Upgraded the mxODBC Connect Server to mxODBC 3.3.2:


MS SQL Server

 * Fixed an "ODBC driver sent negative string size" error when using
   empty strings or None with output parameters for SQL Server ODBC

 * Clarified that due to the way the SQL Server ODBC driver sends
   data, mixing output parameters and output result sets is not
   possible. A work-around for this is to send back output parameters
   as additional result set.

SAP Sybase ASE

 * Added a work-around for the Sybase ASE ODBC driver which has
   problems with BIGINT columns. These are now supported.

 * Fixed a possible "ODBC driver sent negative string size" error when
   using empty strings or None with output parameters for Sybase ASE
   ODBC drivers.


 * Fixed the handling of None as default value for output parameters
   in e.g. stored procedures to use VARCHAR binding rather than CHAR
   binding. The latter caused padding with some database backends.

 * Changed cursor.colcount to be determined on-demand rather than
   right after the prepare step of statement execution.

For the full set of changes, including those of the 2.1 series of
mxODBC Connect, please check the mxODBC Connect change log:
