1.3.4

• Improve compatibility with MySQL Server 8.0.24:
  • Ignore new ER_CLIENT_INTERACTION_TIMEOUT error packet sent to timed-out connections: #970.
  • Known Issue: Connections with UseCompression=true may throw a MySqlProtocolException when timed out.

1.3.3

• Support Enum parameters in prepared commands: #965.
• Fix OverflowException reading OkPayload: #966.
• Fix internal SQL parsing error with C-style comments.

1.3.2

• Fix a bug that could cause a timed-out query to still throw a QueryInterrupted MySqlException instead of CommandTimeoutExpired.

1.3.1

• Remove two new Info log messages added in 1.3.0: #956.
  • The equivalent messages in 1.2.1 were at Debug level.
• Make Adler32 class internal.
  • This was not intended to be added to the public API in 1.3.0.

1.3.0

• Connections are now reset asynchronously in the background: #178.
  • This speeds up MySqlConnection.Open(Async) but still cleans up connections between uses.
  • Use DeferConnectionReset=true in the connection string to revert to the old behaviour.
  • Experimental Use ConnectionIdlePingTime=300 in the connection string to avoid any network I/O when retrieving a connection from the pool; this is fastest but may return invalid connections from Open. This setting is experimental and may change in the future.
• Change default value of IgnorePrepare to false: #929.
  • Calling MySqlCommand.Prepare(Async) will have an effect by default.
• Implement Azure Server Redirection: #789.
  • Support community protocol for server redirection: #945.
• Support MemoryStream as a value for MySqlParameter.Value: #943.
• Implement MySqlException.IsTransient: #849.
• Implement IComparable<MySqlDateTime> and IEquatable<MySqlDateTime> on MySqlDateTime.
• Breaking Remove public constructor for MySqlConversionException.
  • This constructor was never intended to be public.
• Implement serialization for exceptions.
• Report CommandTimeoutExpired consistently: #939.
  • This changes the MySqlException.ErrorCode from QueryInterrupted to CommandTimeoutExpired.
• Nagle's Algorithm is disabled on TCP sockets: #921.
• Adler32 checksum (for compressed packets) uses hardware acceleration: #865.
• Set timeouts for cancellation operations from CancellationTimeout connection string option: #951.
• Throw OperationCanceledException from OpenAsync when the CancellationToken is cancelled: #931.
• Use transaction for 'SHOW WARNINGS': #918.
• Improve exception message for unsupported parameter types: #925.
• Fix exception in server version parsing: #934.
• Fix silent failure to use TLS 1.3 (when explicitly requested) on older frameworks.
• Fix error deserialising MySqlException.ErrorCode property.
• Prevent exceptions being thrown from MySqlTransaction.Dispose: #923.
• Fix nested MySqlException (thrown in some scenarios from ExecuteReader).
• Use .NET 5.0 methods to load PEM certificates.
• Thanks to @novak-as for contributions to this release.
