+## Changes Between 6.3.1 and 6.4.0
+
+This release adds the ability to specify a maximum message size when receiving data. The default
+values are:
+
+* RabbitMQ .NET client 7.0.0 and beyond: 128MiB
+* RabbitMQ .NET client 6.4.0 up to 7.0.0: no limit by default
+
+Receiving a frame that specifies a content larger than the limit will throw an execption.
+
+
+To set a limit, use the `AmqpTcpEndpoint` API and set `MaxMessageSize` before opening connections:
+
+```
+// This sets the limit to 512MiB
+var ep = new AmqpTcpEndpoint("host", 5672) { MaxMessageSize = 536870912 };
+var cf = new ConnectionFactory();
+var conn = cf.CreateConnection(new List<AmqpTcpEndpoint> { ep });
+```
