+Changes between FreeRTOS-plus-TCP V4.3.4 and V4.3.3 released October 10, 2025:
+	+ Fixed possible buffer over read when processing ICMPv6 packets of
+	  certain message types which are smaller than the expected size.
+	+ Fixed missing validation check in IPv6 packet processing code which
+	  can lead to out-of-bounds read when receiving a IPv6 packet with
+	  incorrect payload lengths in the packet header.
+	+ Fixed possible NULL pointer dereference when IPv6 link local endpoint
+	  is not present in the system when IPv6 is enabled.
+	+ Fixed missing validation check in UDP/IPv6 packet processing code which can
+	  lead to invalid pointer dereference when receiving a UDP/IPv6 packet with an
+	  incorrect IP version field in the packet header.
+	  We would like to thank Ivan Gotovchits on behalf of Mayhem Security for
+	  collaborating on above issues through the coordinated vulnerability disclosure process.
