* Refactored and secured BACnetActionCommand codec into bacaction.c module for command object and added to bacapp module encode/decode with define for enabling and pseudo application tag for internal use.
* Simplified bacapp_data_len() and moved into bacdcode module as bacnet_enclosed_data_len() function.
* Secured ReadProperty-REQUEST and -ACK decoding.
* Removed deprecated Keylist_Key() functions from usage.
* Removed pseudo application datatypes from bacapp_data_decode() which only uses primitive application tag encoded values.
* Defined INT_MAX when it is not already defined by compiler or libc.
* Deprecated bacapp_decode_application_data_len() and bacapp_decode_context_data_len() as they are no longer used in any code in the library.
* Added BACnetScale to bacapp module. Improved complex property value decoding. Refactored bacapp_decode_known_property() function.
* Refactored and improved the bacapp_snprintf() function for printing EPICS.
* Fixed Lighting Output WriteProperty to handle known property decoding.
* Reduced MS/TP MAX_APDU to 480 from 1476 so that devices not use new MS/TP extended frame types which older routers do not understand.
* Added extra objects to STM32F4xx example to elicit edge cases in object-list for testing.
* Changed MS/TP master node self destination checks to be located in receive FSM
* Changed MSTP zero configuration: modified comments for state transition names; modified next station increment; refactored the UUID rand() to not be required by common zero config implementation; added more unit tests.
* Added another context to MS/TP user data to allow additional user data
* Refactored ports/xplained to use common DLMSTP module to enable extended frames
* Added floating point compares in cases where they don't exist in math library
* Improved GCC compiler flags in ARM, OS, and test builds. Removed redundant flags, and made them consistent across various builds.
* Fixed redundant redeclaration of various functions detected by change in compiler flags.
* Fixed string truncation warning in bip-init detected by change in compiler flags.
* Fixed some set-but-not-used variables by creating dummy functions instead of using macros.
