 mxODBC - Python ODBC Database Interface

                           Version 3.1.2

    mxODBC is our commercially supported Python extension providing
         ODBC database connectivity to Python applications
            on Windows, Mac OS X, Unix and BSD platforms

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



mxODBC provides an easy-to-use, high-performance, reliable and robust
Python interface to ODBC compatible databases such as MS SQL Server,
MS Access, Oracle Database, IBM DB2 and Informix , Sybase ASE and
Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more:

The "eGenix mxODBC - Python ODBC Database Interface" product is a
commercial extension to our open-source eGenix mx Base Distribution:



mxODBC 3.1.2 Update

The 3.1.2 release of our mxODBC is the latest release of our popular
Python ODBC Interface.

The new patch-level version includes a few important fixes:

 * Fixed a compatibility problem with Python 2.7's distutils that was
   introduced in Python 2.7.3

 * Improved compatibility of the mxODBC native Unicode string format
   handling with Unix ODBC drivers when running UCS4 builds of Python.

Licenses for mxODBC 3.1.x remain valid for mxODBC 3.1.2 as well.

Support for MS SQL Server Native Client for Linux

The above changes allows using the NVARCHAR and NCHAR types of SQL
Server with the *new MS SQL Server Native Client for Linux* with UCS4
Python builds. UCS2 Python builds don't exhibit this issue. The new
driver has proven to be much more feature complete than the FreeTDS
ODBC driver, so it's definitely worth a try.

Note that the MS driver currently has an issue with Unicode connection
strings which causes stack corruption. Please don't use Unicode
connection strings with the MS SQL Server Native Client for Linux
driver, since there's no way we can work around this problem: we only
know the type of driver after connection and then it's already too

You can download the new MS SQL Server Native Client for Linux from:

Windows x64 and eGenix mx Base 3.2

With mxODBC 3.1.1 we had already introduced compatibility with our
current mx Base 3.2 release in order to be able to support the Windows
x64 platform. If you are currently using the combinations mxODBC 3.1.0
+ mx Base 3.1, please consider upgrading to our latest releases mxODBC
3.1 + mx Base 3.2.

eGenix mx Base 3.2 is available from our product page:

New mxODBC Editions

Due to popular demand, we have extended the set of available mxODBC
editions and included a new low-cost standard edition. mxODBC is now
available in these three editions:

    * The low-cost Standard Edition which provides data connectivity
      to a selected set of database backends.

    * The Professional Edition, which gives full access to all mxODBC

    * The Product Development Edition, which allows including mxODBC
      in applications you develop.

At the same time we have simplified our license terms to clarify the
situation on multi-core and virtual machines. In most cases, you no
longer need to purchase more than one license per processor or virtual
machine, scaling down the overall license costs significantly compared
to earlier mxODBC releases.

For a complete overview of the new editions, please see the product page.
