When decoding the optional priority context tag in wp_decode_service_request(), the code passes apdu_len - apdu_size to bacnet_unsigned_context_decode instead of apdu_size - apdu_len. Similar typo in bacnet_action_command_decode().
* Added example Device object and property value backup using create-object list-of-initial-values and writable properties. Initiated using ReinitializeDevice with STARTBACKUP command. Added backup and restore required properties to the Device object.
* Fixed fwrite parameters in bacfile_posix_write_stream_data to return the correct number of bytes written.
* Added Device Management-Backup and Restore-B (DM-BR-B) conversion to Wireshark PCAP format command line utility in apps/dmbrcap which decodes and provides a view of the binary backup file.
* Added Send_UEvent_Notify_Device function for device-specific unconfirmed event notifications.
* Fixed event_notify_parse() loop index to start from zero.
* Added device ID binding support in the UEvent command-line application.
* Fixed the UEvent command-line application help output.
* Fixed initialization of event data in the UEvent command-line application by adding static CharacterString for message text and handling the failure case.
* Added Blink.Callback and Blink.Priority to support end-of-blink actions for WARN_OFF/WARN_RELINQUISH. The Blink.Callback is invoked when a blink sequence ends or when a new command interrupts a WARN_OFF/WARN_RELINQUISH in progress.
* Added Lighting Output (LO) WARN_OFF/WARN_RELINQUISH post-egress priority array handling using the Blink.Callback
* Fixed lighting output object lighting-commands for warn-off and warn-relinquish when blink-warn notification shall not occur.

* Added API to get the RGB pixel and brightness values from the blinkt interface.
* Fixed Channel object for Color object present-value which does not use coercion.
* Added API to the color-RGB library to convert from ASCII CSS color name to X,Y and brightness.
* Converted the Blinkt example app to use the basic-server. Added a default color name command line option --color that accepts CSS color names. Set the color and brightness at startup.
* Added vacancy timer for lights using timer object defaulted to 30m and started at startup.
* Added enumeration text lookup for BACnetAuthenticationStatus, BACnetAuthorizationMode, BACnetAccessCredentialDisable, BACnetAccessCredentialDisableReason, BACnetAccessUserType, BACnetAccessZoneOccupancyState, BACnetWriteStatus, BACnetIPMode, BACnetDoorValue, BACnetMaintenance, BACnetEscalatorFault, BACnetEscalatorMode, BACnetEscalatorOperationDirection, BACnetBackupState, BACnetSecurityLevel, BACnetLiftCarDirection, BACnetLiftCarDoorCommand, BACnetLiftCarDriveStatus, BACnetLiftCarMode, BACnetLiftFault, BACnetLiftGroupMode, BACnetAuditLevel, BACnetAuditOperation, BACnetSCHubConnectorState, BACnetSCConnectionState, BACnetNodeRelationship, BACnetAction, BACnetFileAccessMethod, BACnetLockStatus, BACnetDoorAlarmState, BACnetDoorStatus, BACnetDoorSecuredStatus, and BACnetAccessEvent.
* Created BINARY_PV_MAX with the same semantic meaning as one more than the last valid enumeration, and deprecated MAX_BINARY_PV usage in the examples.
* Reduced code size by using bactext_property_states_strtoul() instead of individual API for each enumations.
Added a new API for writable property lists across all the basic example object types, preparing for the introduction of a Writable_Property_List property in every object in a future BACnet standard revision.
The lists can be used by backup and restore feature to automatically choose the object property values in the backup that can be restored via internal WriteProperty directly from BACnet CreateObject services with List of Initial Values.
Updated existing device object examples to include these writable property lists.
* Fixed lighting output object lighting-command last-on-value to only
be updated with the last value of the Present_Value property that
was greater than or equal to 1.0%, keeping in mind that the Present_Value
shall indicate the target level of the operation and not the current
value.
Fixes the CreateObject service list-of-initial-values encoding and decoding by refactoring the data structure to be similar to WriteProperty. The implementation changes from using a linked list of property values to using a flat buffer approach with delayed decoding.
Changes:
* Refactored BACNET_CREATE_OBJECT_DATA structure to use an application_data buffer instead of a linked list for initial values
* Added a new create_object_process() and create_object_initializer_list_process() functions to centralize object creation logic and error reporting
* Updated all device implementations to use the new centralized creation functions
* Enhanced the create-object example application to support command-line specification of initial property values
* Added comprehensive test coverage for the new encoding/decoding and processing functions
