Functionality Added or Changed

  • Added .NET 9 GA and EF Core 9 GA support, and removed .NET 6 and EF Core 6 support. (WL #16638, WL #16654)

Bugs Fixed

  • The MySql.Data.OpenTelemetry.dll metadata reported the version as 0.0.0.0. (Bug #37198051)

  • Added ROW_COUNT() concurrency checking in EFCore for update operations.

    Our thanks to Ryan Kelly for the contribution. (Bug #115853, Bug #36960454)

  • The MySQLUpdateSqlGenerator class now inherits from UpdateAndSelectSqlGenerator instead of UpdateSqlGenerator.

    Our thanks to Hikari Fujioka for the contribution. (Bug #115020, Bug #36624158)

  • Added a NULL check to the MySQLActivitySource class.

    Our thanks to Maximilian Bienhüls for the contribution. (Bug #114457, Bug #36568102)

  • Added a new rewritebatchedstatements connection option that makes the connector rewrite batched statements and execute them all at once in a single block rather than one at a time, which is default behavior.

    Note that this connection option impacts functions like LAST_INSERT_ID().

    Our thanks to Sebastian Schwarzhuber for the contribution. (Bug #110553, Bug #35240186)
