Fix ArgumentException in MySqlBulkCopy: #974.

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.

1.3.0

Connections are now reset asynchronously in the background: #178.

- 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.

- 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.
