This page discusses what was added in each version of the Microsoft OLE DB Driver for SQL Server.

What's new in version 18.2.1

Features added:

• Support for UTF-8 server encoding. For more information, see: UTF-8 Support in OLE DB Driver for SQL Server.
• Azure Active Directory authentication support. For more information, see: Using Azure Active Directory.

What's new in version 18.1.0

Features added:

• Support for UseFMTONLY connection string keyword and SSPROP_INIT_USEFMTONLY initialization property. UseFMTONLY controls how metadata is retrieved when connecting to [!INCLUDEssSQL11] and newer.
  For more information, see:
  • Using Connection String Keywords with OLE DB Driver for SQL Server

Bugs fixed:

• Fixed incorrect version of the BCP format file. The OLE DB Driver 18.0 incorrectly sets the version of the BCP format file to 18.0 instead of 11.0. Format files generated by the OLE DB Driver 18.0 cannot be read by the OLE DB Driver 18.1. If you need to use format files generated by the previous version of the driver with the new driver, you can manually edit the files to change the version to 11.0.

What's new in version 18.0.2

Features added:

• Support for MultiSubnetFailover connection string keyword and SSPROP_INIT_MULTISUBNETFAILOVER initialization property.
  For more information, see:
  • OLE DB Driver for SQL Server Support for High Availability, Disaster Recovery
  • Using Connection String Keywords with OLE DB Driver for SQL Server
