Version 5.1.0 - 27 Oct 2019
- Refactored to remove all static variables and replace them with dynamically loaded variables assigned to a stack object. This makes it possible to run multiple instances of a BACnet driver with each instance isolated from the other. Each driver maintains it's own list of networks, devices and objects.
- Refactored to pass the stack object to the function calls. The calling application must pass the stack object to service requests to use the appropriate BACnet driver.
- Introduced Channels to the stack for multiple instances of the BACnet Driver.
- Added a new constructor to the CBACnetDriver class to specify the channel name associated with the class. If multiple CBACnetDriver classes are instanciated then each instance must have it's own unique name. If no name is given then only 1 CBACnetDriver class is allowed within the application.
- Added new constructors to all BACnet service class to set the CBACnetDriver to be used.

- Optimised the EDE file loader.
- When the notificationClass recipientList property contains a destination with the recipient type set to BACnetAddress and issueConfirmedTransactions is set to false then an event may not be sent. The API does not send out a whoIs request for dynamic binding and the events are held in the queue until an Iam is received which prevents the event message from being sent.
- The status flags property in the character string object does not update after writing to the outOfService property.
- Unconfirmed Event notification messages are not being broadcast onto the local network.
- When writing to a property with a TimeValue type the API does not return a valueOutOfRange error when if the time has a wildcard value. For example Any Minute for the Hour 12. The value should only be accept values for a specified time.
- When writing to a property with a DateRange type the API does not return a valueOutOfRange error when if the date has a wildcard value. For example Any Month in the Year 2018. The value should only be accept for a specified date, or an unspecified date.
- After receiving an AckAlarm Service, the API sends a confirmedEvent message with an invalid priority.

- If the presentValue object of AnalogValue, BinaryValue and MultistateValue objects are not commandable then the stack returns writeAccess denied even though the property has been configured as readWrite.
- When writing to the recipient list the fromDate and toDate should only accept a specific time. Wildcard or unspecified times should return a valueOutOfRange error when writing to the recipient list.
- Implemented the wildcard address of 4194303 for the network port object.
- Added additional callback functions to the ASN1 property maps to set the access level and to determine if a property is excluded. Removed unused callback functions from the property map.

- The bacnet api does return an error when the createObject service is executed with invalid properties.
- Incorrect required properties returned from MultistateOutput, Schedule, CharacterString and NetworkPort objects.
- Incorrect update interval for cache points that use readProperty or readPropertyMultiple.
- PDU parser should return inconsistent parameters when a packet fails to be decoded. It currently returns "constructed" data when decoding fails.

- Revised the name of some internal properties in the cache module.
- Revised the device discovery timeout to prevent service requests from timing out before a whoIs request has been sent.
- If the cache module is using COV notifications then it should remove the subscriptions before it stops. The CBACnetDriver::Stop() method has 2 additional parameters which can be used to unsubscribe from the devices before shutdown. There is a new function called ShutdownInProgress() which can be called to detirmine if all the subscriptions have been sent.
- When there is a subscribeCOV error within the cache module it will automatically revert to polling with readProperty or readPropertyMultiple. After the resubscription time has expired attempt to resubscribe to the point again. After 3 attempts permanently revert to polling.

- If the priorityArray and reliablity properties are set to NOT_SUPPORTED for commandable objects (eg AnalogOutput) then a BACnet client is still able to write to the object and internal writes no longer work as expected.
- When operating as a BBMD the stack will rebroadcast an invalid packet if it receives a Forwarded NPDU. This bug was introduced in release 5.0.15 after changes were made to allocate memory statically.
- Updated the cache module to send multiple parallel requests to a device. For example if a device only supports readProperty then allow up maxTsmQty parallel requests per device to be sent.
- Added a new helper function SetMaxTsmQuantity() to configure the property for each device. There is a global setting for maxTsmQty and this setting is used as the default value for a device which can then be set at the device level.
- The ServiceAck pdu decoding fails if the response type is a BACnet Error.
- The BACnetCharacterset transmitted datatype is not set to zero in some methods resulting in an incorrect encoding/decoding of the character set.
