We are pleased to announce the new version 2.1.1 of our mxODBC
Zope/Plone Database Adapter product.

Feature Enhancements

 * Added a new connection property "ODBC cursor type" which allows
   easily adjusting the ODBC cursor type to be used for mxODBC Zope DA
   connection objects.

   This new property allows enhancing the performance of the adapter
   significantly, when using it with MS SQL Server or IBM DB2 database
   backends. Please see below for details.

Driver Compatibility

 * MS SQL Server performance can now be much enhanced, and increased
   to levels beyond that of previous mxODBC Zope DA releases, by
   adjusting the connection ODBC cursor type to "Forward only

   The performance increase compared to mxODBC Zope DA 2.1.0 is
   enormous: from 2-3x faster executes/fetches for average queries, up
   to 300x faster for simple cases.

   In mxODBC Zope DA 2.2, we will switch to using "Forward only
   cursors" per default for all database backends.

 * IBM DB2 can benefit from the same performance enhancements using
   "Forward only cursors".

   The effect is a lot smaller, but still noticeable: up to 2x faster
   executes/fetches with forward-only cursors, compared to mxODBC Zope
   DA 2.1.0.

 * Added documentation to explain the different cursor types,
   compatibility with different database backends and effects on


 * Fixed the installation instructions to be more generic and easily
   adaptable to Plone and Zope installations on both Windows and Unix
