+_Ref 10.5.1_
+- MISRA C-2012 Rule 10.5 states that the value of an expression should not be cast to an inappropriate essential type. In this library, reason codes are input as bytes and processed accordingly. A byte representing the reason code is cast to an enumerated type that is also based on uint8_t. It is verified that the values will always fall within the valid range of the enumeration, and the underlying type of the enumeration is compatible. Thus, this cast is considered safe.

### Breaking Changes
@@ -232,3 +232,1647 @@ if( status == MQTTSuccess )
### Additional Changes
* The `MQTT_CancelCallback` function has been added to allow a program to prevent the event callback from being called when receiving an ACK for a sent packet. For example, if a program sends a publish with packet ID 2 and QoS > 0 using `MQTT_Publish`, the program could then call `MQTT_CancelCallback` on packet ID 2 to prevent coreMQTT from calling the event callback when it receives the `PUBACK` for packet ID 2.
+
+## coreMQTT version >=v3.0.0 Migration Guide
+
+With coreMQTT versions >=v3.0.0, there are some breaking changes that need to be addressed when upgrading.
+
+### Breaking Changes
+
+* The `MQTTEventCallback_t` function signature used in `MQTT_Init` has changed to support MQTT v5 properties and reason codes. The signature changed from `void (* MQTTEventCallback_t)( struct MQTTContext * pContext, struct MQTTPacketInfo * pPacketInfo, struct MQTTDeserializedInfo * pDeserializedInfo )` to `void (* MQTTEventCallback_t)( struct MQTTContext * pContext, struct MQTTPacketInfo * pPacketInfo, struct MQTTDeserializedInfo * pDeserializedInfo, enum MQTTSuccessFailReasonCode * pReasonCode, struct MQTTPropBuilder * sendPropsBuffer, struct MQTTPropBuilder * getPropsBuffer )`. For example:
+
+**Old Code Snippet**:
+```
+// Callback function implementation
+static void eventCallback(
+ MQTTContext_t * pContext,
+ MQTTPacketInfo_t * pPacketInfo,
+ MQTTDeserializedInfo_t * pDeserializedInfo )
+{
+ /* Handle incoming publish. The lower 4 bits of the publish packet
+ * type is used for the dup, QoS, and retain flags. Hence masking
+ * out the lower bits to check if the packet is publish. */
+ if( ( pPacketInfo->type & 0xF0U ) == MQTT_PACKET_TYPE_PUBLISH )
+ {
+ /* Handle incoming publish. */
+ }
+ else
+ {
+ /* Handle other packets. */
+ }
+}
+
+// MQTT_Init call
+status = MQTT_Init( &mqttContext,
+ &transport,
+ getTimeMs,
+ eventCallback,
+ &fixedBuffer );
+```
+**New Code Snippet**:
+```
+// Callback function implementation
+static void eventCallback(
+ MQTTContext_t * pContext,
+ MQTTPacketInfo_t * pPacketInfo,
+ MQTTDeserializedInfo_t * pDeserializedInfo,
+ MQTTSuccessFailReasonCode * pReasonCode,
+ MQTTPropBuilder_t * sendPropsBuffer,
+ MQTTPropBuilder_t * getPropsBuffer )
+{
+ /* Handle incoming publish. The lower 4 bits of the publish packet
+ * type is used for the dup, QoS, and retain flags. Hence masking
+ * out the lower bits to check if the packet is publish. */
+ if( ( pPacketInfo->type & 0xF0U ) == MQTT_PACKET_TYPE_PUBLISH )
+ {
+ /* Handle incoming publish. */
+
+ /* Access publish properties if needed */
+ uint16_t topicAlias;
+ if( MQTTPropGet_PubTopicAlias( getPropsBuffer, &topicAlias ) == MQTTSuccess )
+ {
+ /* Handle topic alias */
+ }
+ }
+ else
+ {
+ /* Handle other packets. */
+
+ /* Add properties to outgoing ack packets if needed */
+ if( pPacketInfo->type == MQTT_PACKET_TYPE_PUBACK )

+ }
+ }
+}
+
+// MQTT_Init call

+ &transport,
+ getTimeMs,
+ eventCallback,
+ &fixedBuffer );
+```
+* The `MQTT_InitStatefulQoS` function now includes support for MQTT v5 properties in outgoing publish acknowledgments with two additional parameters. Thus, the signature of `MQTT_InitStatefulQoS` changed from `MQTTStatus_t MQTT_InitStatefulQoS( MQTTContext_t * pContext, MQTTPubAckInfo_t * pOutgoingPublishRecords, size_t outgoingPublishCount, MQTTPubAckInfo_t * pIncomingPublishRecords, size_t incomingPublishCount )` to `MQTTStatus_t MQTT_InitStatefulQoS( MQTTContext_t * pContext, MQTTPubAckInfo_t * pOutgoingPublishRecords, size_t outgoingPublishCount, MQTTPubAckInfo_t * pIncomingPublishRecords, size_t incomingPublishCount, uint8_t * pBuffer, size_t bufferLength )`. The new parameters can be set to NULL and 0 respectively if not using MQTT v5 properties in publish acknowledgments. For example:
+
+**Old Code Snippet**:
+```
+// Variables used in this example.
+MQTTContext_t mqttContext;
+const size_t outgoingPublishCount = 10;
+const size_t incomingPublishCount = 10;
+MQTTPubAckInfo_t pOutgoingPublishRecords[ outgoingPublishCount ];
+MQTTPubAckInfo_t pIncomingPublishRecords[ incomingPublishCount ];
+
+status = MQTT_InitStatefulQoS( &mqttContext,
+ pOutgoingPublishRecords,
+ outgoingPublishCount,
+ pIncomingPublishRecords,
+ incomingPublishCount );
+
+if( status == MQTTSuccess )
+{
+ // QoS > 0 operations can now be performed
+}
+```
+**New Code snippet**:
+```
+/ Variables used in this example.
+MQTTContext_t mqttContext;

+MQTTPubAckInfo_t pOutgoingPublishRecords[ outgoingPublishCount ];
+MQTTPubAckInfo_t pIncomingPublishRecords[ incomingPublishCount ];
+
+// Option 1: Without MQTT v5 properties in publish acknowledgments
+status = MQTT_InitStatefulQoS( &mqttContext,
+ pOutgoingPublishRecords,
+ outgoingPublishCount,
+ pIncomingPublishRecords,
+ incomingPublishCount,
+ NULL, // No buffer for properties
+ 0 ); // No buffer length
+
+// Option 2: With MQTT v5 properties in publish acknowledgments
+uint8_t propertyBuffer[500];
+status = MQTT_InitStatefulQoS( &mqttContext,
+ pOutgoingPublishRecords,
+ outgoingPublishCount,
+ pIncomingPublishRecords,
+ incomingPublishCount,
+ propertyBuffer, // Buffer for properties
+ sizeof(propertyBuffer) );
+
+if( status == MQTTSuccess )
+{
+ // QoS > 0 operations can now be performed
+}
+```
+* The `MQTT_Connect` function now includes MQTT v5 property support with two additional parameters. Thus, the signature of `MQTT_Connect` changed from `MQTTStatus_t MQTT_Connect( MQTTContext_t * pContext, const MQTTConnectInfo_t * pConnectInfo, const MQTTPublishInfo_t * pWillInfo, uint32_t timeoutMs, bool * pSessionPresent )` to `MQTTStatus_t MQTT_Connect( MQTTContext_t * pContext, const MQTTConnectInfo_t * pConnectInfo, const MQTTPublishInfo_t * pWillInfo, uint32_t timeoutMs, bool * pSessionPresent, const MQTTPropBuilder_t * pPropertyBuilder, const MQTTPropBuilder_t * pWillPropertyBuilder )`.`pPropertyBuilder` and `pWillPropertyBuilder` can be set to NULL if the user does not want to send any properties.

+if( status == MQTTSuccess )
+{

+```
+* The `MQTT_Subscribe` function now includes support for MQTT v5 properties with an additional parameter. Thus, the signature of `MQTT_Subscribe` changed from `MQTTStatus_t MQTT_Subscribe( MQTTContext_t * pContext, const MQTTSubscribeInfo_t * pSubscriptionList, size_t subscriptionCount, uint16_t packetId )` to `MQTTStatus_t MQTT_Subscribe( MQTTContext_t * pContext, const MQTTSubscribeInfo_t * pSubscriptionList, size_t subscriptionCount, uint16_t packetId, const MQTTPropBuilder_t * pPropertyBuilder )`. The new parameter can be set to NULL if not using MQTT v5 properties. For example:

-@brief MQTT 3.1.1 client library
+@brief MQTT 5.0 client library
> MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging "machine-to-machine" (M2M) or "Internet of Things" world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.

+@ref mqtt_connect_function accepts a timeout parameter for packet reception.
For the @ref mqtt_connect_function, if this value is set to 0, then instead of a time-based loop, it will attempt to call the transport receive function up to a maximum number of retries,

-Should the timeout be set to 0, then the loop will run for a single iteration. A single iteration of a loop consists of an attempt to receive a single byte from the network, and

+For @ref mqtt_processloop_function and @ref mqtt_receiveloop_function, the timeout functionality is handled by the user application. It is up to the user to define the number of times these functions will be called, provided that there are no network errors.
+A single call to the function consists of an attempt to receive all available bytes from the network, and if the read was successful, then attempt(s) to receive the rest of the packet (with retry attempts governed by @ref MQTT_RECV_POLLING_TIMEOUT_MS), followed by the deserialization of the received packet.
