- Added serial-number property to basic device object example. (#789)
- Added optional description property to basic network port object example. (#788)
- Added ucix_get_list and ucix_set_list function. (#780)

- Added BACnet Ethernet support for MacOS X via pcap library. (#775)
- Added local tool aptfile to use with apt based development installation. (#772)
- Added MS/TP support for MacOS X. (#764)
- Added pre-commit clang-format 17 format check in pipeline. Formatted entire code base except external/ folders. (#755)
- Added RP and RPM error code indications in callbacks in bac-rw.c module handling. (#756)
- Added editorconfig, a widely used and supported file in profession IDEs. The configuration file indicates how files should be formatted. (#753)

This can also be used in the pipeline during a pull-request for automated checking. pre-commit can also be used in a local workspace or within an IDE. pre-commit makes it easy to select clang-format version so everyone is using same one.
- Added basic object-name get for ASCII names to enable free if they were dynamically created. Added unit testing to validate the basic object ASCII object-name API. (#754)
- Changed the lint apt install in quality pipeline to be consistent (#837)
- Changed apps/epics by enabling BACnetARRAY checking. (#823)
- Changed BACnet Ethernet and IPv6 on win32 by switching from WinPcap to npcap. Included npcap SDK in cmake and libs for IPv6 in cmake. (#774)
- Changed pipeline gcc.yml to reduce known warnings from legacy API by adding LEGACY flag to make bip-apps with GNU99. (#795)
- Changed ATmega168 example for ATmega328 on Arduino Uno R3 with DFR0259 RS485 shield. Added ADC interface from BDK port and mapped to some AV objects. Removed MS/TP MAC address DIP switch GPIO and moved MS/TP configuration to AV objects. Added AV units property. Added some Uno R3 Digital Inputs and outputs mapped to some BV. Added AVR EEPROM from BDK port and mapped some non-volatile data including MAC address and max manager and baud rate, device ID and names and description and location. (#784)
- Changed the datalink abstraction to enable selecting multiple datalinks using BACDL_MULTIPLE and one or more other BACDL defines. (#717)
- Moved west manifest, zephyr folder, and ports/zephyr folders to another repository https://github.com/bacnet-stack/bacnet-stack-zephyr so that the rapid pace of Zephyr OS development changes will have a less impact on the development of the BACnet Stack library. (#757)
- Removed static scope on character array used for object-name since the array gets copied into characterstring array and static is not needed. (#754)
- Changed clang-format rules to always align const to left side, and insertbraces to avoid having to use clang-tidy. (#753)

- 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 we got a warning that the 4th function call argument is an uninitialized value in bacapp_snprintf_weeklyschedule(). Fixed the warning by setting array_index to zero. (#714)

(#553)
- 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)

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