Microsoft OLE DB Driver for SQL Server 19.4.3

What's new in 19.4.3

Features added

| Feature added | Details |
| ----------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Added USERAGENT feature extension | The driver sends its name, version, architecture, and operating system details to the server in the LOGIN7 USERAGENT TDS feature extension. |
| Added canonical connection string aliases | Added the ConnectTimeout, MultipleActiveResultSets, and WorkstationID keywords as aliases for the Timeout, MarsConn, and WSID keywords. The existing keywords continue to work. |
| Added redirect context to connection failure messages | When the server routes a connection to another server and the connection to that server fails, the driver adds an error that names both the target server and the server that redirected the connection. |
| Added support for enhanced routing | Supports enhanced routing for Azure SQL Database Hyperscale named-replica reader endpoints. The driver connects to the server and the database that the server's routing information specifies. |
| Updated authentication library | Updated Microsoft SQL Driver Authentication library (mssql-auth.dll) to version 1.1.4. This update fixes a crash when an application unloads and reloads the library after authentication starts. |
