Changes in MySQL Connector/NET 9.3.0 (2025-04-15, General Availability)

Functionality Added or Changed

  • The following are the updated version requirements of Connector/NET on some of the third-party libraries it uses (see Connector/NET Installation for details):

    • Google Protobuf .NET version 3.30.0

    • ZstdSharp version 0.8.5

    • Kerberos version 1.21.3

    • BouncyCastle version 2.5.1.

    • OpenTelemetry .NET version 1.11.2

    (WL #16852)

Bugs Fixed

  • The test GetSchemaReturnColumnsByOrdinalPosition() in the testsuite failed because the server has changed the precision for displaying floating values resulted from arithmatic operations. The patch fixes the test. (Bug #37705281)

  • Performing a database migration using MySql.EntityFrameworkCore 9.0.0 or later resulted in a SQL syntax error. (Bug #117258, Bug #37513445)

  • Timeout testing for Connector/NET used non-existing server addresses, which caused unexpected behaviors. With this fix, the tests now use mock servers instead. (WL #16033)
