 ### Added
 
+* Added parsing for BACnetSpecialEvent in bacapp for use in apps/writeproperty
+  and add unit tests. (#1290)
+* Added multi-device support for BACnet gateway routing. Expanded Object_List
+  to Object_List[MAX_NUM_DEVICES] array to support per-device objects for
+  virtual remote devices. Added multi-device iteration for COV handler,
+  device timer, and intrinsic reporting. Added apps/gateway2 demo application.
+  When MAX_NUM_DEVICES == 1, behavior is identical to the original
+  gateway implementation. Conditional compilation with macros ensures
+  no impact on non-gateway applications. (#1279)
 * Added structured-view object subordinate-list add, remove, exist, same
   API for interfacing as a list.  Added purge API for unit testing. (#1283)
 * Added ports/pico for Raspberry Pi Pico port of the BACnet stack
