## [Unreleased] - 2026-02-06

### Security

* Secured Schedule_Weekly_Schedule_Set() the example schedule object
  by fixing stack buffer overflow. The memcpy was using
  sizeof(BACNET_WEEKLY_SCHEDULE) instead of sizeof(BACNET_DAILY_SCHEDULE),
  causing it to read 6784 bytes from a 968-byte source buffer, leading
  to stack buffer overflow and segmentation fault in the test_schedule
  unit test. (#1222)
* Secured npdu_is_expected_reply() function where the MS/TP reply matcher
  could have an out-of-bounds read. (#1178)
* Secured ubasic interpreter tokenizer_string() and tokenizer_label()
  off-by-one buffer overflow when processing string literals longer
  than the buffer limit.
  Fixed ubasic potential string buffer overflows by using snprintf.
  Fixed ubasic label strings to use UBASIC_LABEL_LEN_MAX as buffer limit.
  Fixed ubasic string variables to initialize with zeros.
  Fixed compile errors when UBASIC_DEBUG_STRINGVARIABLES is defined.
  Added ubasic string variables user accessor API and unit testing. (#1196)
* Secured BACnet file object pathname received from BACnet AtomicWriteFile
  or ReadFile service used without validation which was vulnerable to
  directory traversal attacks. (#1197)

### Added

* Added Device Management-Backup and Restore-B to example object/device.c
  and basic/server/bacnet-device.c so that when ReinitializeDevice STARTBACKUP
  is requested a backup file is stored in CreateObject format for all the
  writable properties in the device. (#1223)
* Added apps/dmbrcap for Device Management-Backup and Restore to convert
  a backup file encoded with CreateObject to Wireshark PCAP format. (#1223)
* Added segmentation support functions and example changes, but
  no support for segmentation in the TSM or APDU handlers. (#1218)
* Added channel and timer object write-property observers in blinkt app
  to monitor internal writes. Added vacancy timer command line argument
  for testing initial timer object vacancy time for lights channel. (#1212)
* Added debug prints for lighting output properties to assist in identifying
  out-of-range values. (#1211)
* Added API to get the RGB pixel and brightness values from the blinkt
  interface. Added API to the color-RGB library to convert from ASCII
  CSS color name to X,Y and brightness. Added a default color name command
  line option. Set the color and brightness at startup. Changed the Blinkt
  example app to use the basic-server framework. (#1210)
* 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. (#1209)
* 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 objects to include
  these writable property lists. (#1206)
* Added post-write notifications for channel, timer, and loop objects. (#1204)
* Added device WriteProperty callbacks for Timer object in example device
  objects implementations. (#1203)
* Added file path name checking for AtomicReadFile and AtomicWriteFile
  example applications. Prohibits use of relative and absolute file paths
  when BACNET_FILE_PATH_RESTRICTED is defined non-zero. (#1197)
* Added API and optional properties to basic load control object example
  Refactored BACnetShedLevel encoding, decoding, and printing into separate
  file. Added BACnetShedLevel validation testing. (#1187)
* Added API for Analog_Input_Notification_Class, Analog_Input_Event_Enable,
  and Analog_Input_Notify_Type. (#1184)

  broadcast address in npdu_send_what_is_network_number() API.  (#1169)
* Added BACnetRecipient and BACnetAddressBinding codecs for EPICS application.
  The implementation includes full encode/decode, ASCII conversion,
  comparison, and copy functions for both data types, along with
  comprehensive test coverage and supporting string utility functions.
  Integrated the new types into the application data framework with
  application tag assignments. (#1163)
* Added library specific string manipulation utilities including strcmp,
  strncmp, and snprintf with offset functions. (#1163)(#1164)
* Added default option to bactext name functions so that NULL can be
  returned when a name does not exist. (#1160)
* Added library specific ltrim, rtrim, and trim string functions. (#1159)
* Added library specific itoa, ltoa, ultoa, dtoa, utoa, and general
  print format with ASCII return functions. (#1157)

  Added library specific string-to functions for BACnet primitives. (#1151)

### Changed

* Changed the default BACnet protocol revision to 28 to enable usage of
  special lighting output values. (#1211)
* Changed bacnet_strtof and bacnet_strtold functions to use strtod to
  improve compatibility with C89 standards while ensuring proper type
  casting and range checking. (#1207)
* Changed RGB color clamp function to avoid Zephyr RTOS name collisions. (#1201)
* Changed the load control object AbleToMeetShed to only check for immediate
  shed ability and added CanNowComplyWithShed function to attempt to meet the
  shed request while in the non-compliant state. (#1191)
* Changed the size of MAX_HEADER in BACDL_MULTIPLE because 8 is not
  big enough for some datalinks (e.g. mstp). (#1170)
* Changed printf() in many apps to use debug_printf() and friends. (#1168)
* Changed apps to use common BACnet value string parsing functions. (#1152)
* Changed basic object API for units properties to use BACNET_ENGINEERING_UNITS
  datatype. (#1104)

  BACnet property enumerations when an int is 8-bit or 16-bit in size. (#1145)

### Fixed

* Fixed bacfile-posix file write to return the number of bytes written. (#1223)
* Fixed Event parsing and help text for the example uevent and event apps.
  Fixed initialization of event data by adding static CharacterString for
  message text. Fixed the event parsing to start at argument zero. (#1221)

  of unsigned. (#1220)
* Fixed handling for abort and reject errors in Write Property service. (#1216)
* Fixed lighting output object lighting-commands for warn-off and
  warn-relinquish when an update at the specified priority slot
  shall occur after an egress time delay. (#1214)
* Fixed lighting output object lighting-commands for warn-off and
  warn-relinquish when blink-warn notification shall not occur. (#1212)
* Fixed timer object task to initiate a write-request at expiration. (#1212)
* Fixed the server name in the blinkt app and removed the unnecessary
  device.c module. (#1211)
* Fixed Channel object for Color object present-value which does not
  use coercion. (#1210)
* 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. (#1205)
* Fixed CreateObject service list-of-initial-values encoding and decoding.
  Changed the data structure to be similar to WriteProperty. (#1199)
* Fixed lighting-output object blink warn to honor blink-warn-enable.
  Fixed the blink warn logic for a non-zero percent value blink inhibit.
  Fixed the warn relinquish to actually relinquish. (#1192)
* Fixed channel-value encoding in the channel object when no-coercian
  is required for lighting-command, color-command, and xy-color. (#1190)
* Fixed NULL handling in CharacterString sprintf which caused an endless
  loop. (#1189)
* Fixed a regression in the rpm_ack_object_property_process() function
  that prevented proper parsing of multi-object ReadPropertyMultiple ACK
  responses. The bug was introduced in PR [#765] and caused the function
  to incorrectly return ERROR_CODE_INVALID_TAG after processing the
  first object, even when additional valid objects were present in
  the response. Added tests that use rpm_ack_object_property_process()
  with a multi-object RPM ACK to verify the fix and prevent regression. (#1183)
* Fix warnings during unit testing of BACnet secure connect node. (#1182)
* Fixed the BACnetChannelValue coercion function to include all the coercions,
  no coercions, and invalid datatypes described in Table 12-63 of the Channel
  object.  Expanded unit testing code coverage for BACnetChannelValue. (#1181)
* Fixed the Channel object to handle all data types that do not need
  coercion when written. Fixed present-value when no value is able to
  be encoded. (#1176)
* Fixed the Loop object read/write references and manipulated variables
  update during timer loop by adding callbacks to device read/write property
  in basic example device object. (#1175)
* Fixed library specific strcmp/stricmp functions match standard strcmp. (#1173)
* Fixed compiler macro redefined warning when optional datatypes are defined
  globally. (#1172)
* Fixed copy and compare API of BACnetObjectPropertyReference structure. (#1171)
* Fixed array-bounds on BACnetObjectPropertyReference parsing. (#1167)
* Fixed the missing BACnetObjectPropertyReference,
  BACnetSCFailedConnectionRequest, BACnetSCHubFunctionConnection,
  BACnetSCDirectConnection,BACnetSCHubConnection, BACnetTimerStateChangeValue,
  and BACnetAddressBinding text used in debugging.(#1166)
* Fixed the units to/from ASCII to function for other units properties. (#1165)
* Fixed datetime integer overflow on 8-bit AVR compiler (#1162)
* Fixed the ports/linux BACnet/IP cache netmask for accurate subnet
  prefix calculation implementation which had always returned 0. (#1155)
* Fixed the loop object empty reference property by initializing to self.
  When configured for self, the manipulated property value will update
  the controlled variable value for simulation.(#1158)
* Fixed unit test stack corruption from using stack based message text
  characterstring pointer in multiple functions and setting the value
  in the global event and test event data structures. (#1154)
* Fix timesync recipient encoding to check for OBJECT_DEVICE type before
  encoding. (#1153)
* Fixed segmented ComplexACK in MS/TP by adding postpone reply because
  transmission of the segmented ComplexACK cannot begin until the node
  holds the token. (#1116)

  files in different folder. For some tools we can just exclude
  external folder all together. (#744)
* Changed most of the functions use of pointer parameters to const.
  Used clang-tidy and sonarlint to help find places where const could be
  easily applied. (#714)
* Changed bacapp_snprintf_value() to be const correct. After that

  builds.  This change places bacnet/bacdef.h to the top of the BACnet
  Stack header files to consistently introduce integrator and ports
  header files.(#598)(#600)

* Added missing object functions to analog inputs and values. (#568)

### Changed

* Changed BACnet R/W FSM module to remove dependency on
  rpm_ack_decode_service_request() which uses large calloc/free
  value lists. Created an alternate RPM-ACK to RP-ACK processing
  function. (#583)
* Changed basic RPM handler to skip over unknown property values. (#583)

  and refactoring the service requests from the service header,
  adding APDU size checking and length features, and adding unit
  tests to check for length when passing NULL buffer:
  ARF/AWF/COV/CO/DO/DCC/Event/GE/ALE/RLE/LSO/RD/RR/RP/WP. (#553)

### Added

* Added bacapp decoding for accumulator SCALE property. (#566)
* Added a MS/TP zero-config (automatically choose an unused MAC address)
  using an algorithm that starts with MAC=64 and waits for a random number
  of PFM (minimum of 8 plus modulo 64) before attempting to choose a MAC
  sequentially from 64..127. The confirmation uses a 128-bit UUID with the
  MSTP Test Request frame. The modifications are in src/bacnet/datalink/mstp.c
  and src/bacnet/datalink/dlmstp.c modules enabling any device to use
  zero-config if enabled. A working demonstration is in the ports/stm32f4xx
  for the NUCLEO board. Complete unit testing is included.  Options include
  lurking forever (wait for a router or another master node before joining)
  or lurking for a minimum time (enables self forming automatic MAC addressing
  device nodes). (#564)

### Changed

* Modified example objects to support CreateObject and DeleteObject API for
these objects: file, analog output, binary output, multi-state output, color,
color temperature).
* Unit tests and functional tests have been moved from the source C files
into their own test files under the test folder in a src/ mirrored folder
structure under test/. 
* The testing framework was moved from ctest to ztest, using CMake, CTest, and LCOV. 
It's now possible to visually view code coverage from the testing of each file
in the library. The tests are run in continuous integration.  Adding new tests
can be done by as copying an existing folder under test/ as a starting point, and
adding the new test folder name into the CMakeLists.txt under test/ folder, or
editing the existing test C file and extending or fixing the existing test. 
* Most (all?) of the primitive value encoders are now using a snprintf()
style API pattern, where passing NULL in the buffer parameter will
return the length that the buffer would use (i.e. returns the length that the
buffer needs to be).  This makes simple to write the parent encoders to check
the length versus their buffer before attempting the encoding at the expense of
an extra function call to get the length.
* BACnetARRAY property types now have a helper function to use for encoding (see bacnet_array_encode) 

## Deprecated

* Added BACNET_STACK_DEPRECATED for functions which will be removed in a future
release, with a suggested replacement function to use instead.
