Starburst ODBC Driver Release Notes 
==============================================================================

The release notes provide details of enhancements, features, known issues, and
workflow changes in Starburst ODBC Driver 2.0.9.1012, as well as the version 
history. 


2.0.9.1012 ===================================================================

Released 2022-07-20

Enhancements & New Features

 * [PRESO-851] User impersonation support 

   The driver can now delegate all operations against the SEP server to the
   specified user, rather than to the authenticated user for the connection. 
   To do this, set the sessionUser, EffectiveUserName, or DelegationUID 
   property to the specified value. For more information, see the Installation
   and Configuration Guide. 


Resolved Issues
The following issues have been resolved in Starburst ODBC Driver 2.0.9.1012.

 * [PRESO-823] When installing the driver, the driver displays an incorrect
   file path.

 * [PRESO-836] SSL errors display incorrect error messages. 
 
 * [PRESO-881] When IgnoreBrokenCatalog is enabled, the driver sends an
   incorrect query. 


Known Issues 
The following are known issues that you may encounter due to limitations in 
the data source, the driver, or an application. 

 * Implicit casting of CHAR(x) to larger CHAR(x) is not supported

   Beginning with version 0.152.1-t, Starburst does not support implicit 
   casting of CHAR(x) data to a CHAR(x) of a larger size. As a workaround, 
   INSERT queries into columns of CHAR(x) type must contain an explicit cast 
   into a CHAR(x) type of the size reported by the Starburst Server.
   
 * [PRESO-681] Some year values not supported in TIME and TIMESTAMP

   The driver does not support year values less than -9999 or greater than 
   9999 in TIME and TIMESTAMP data types.
