+Changes between FreeRTOS-plus-TCP V4.2.0 and V4.1.0 released June 24, 2024
+    + It was possible for a carefully crafted DNS response with domain name
+      length value greater than the actual domain name length, to cause a buffer
+      over-read within the DNS Response Parser. This issue affects applications
+      using DNS functionality of the FreeRTOS-Plus-TCP stack.
+      Applications that do not use DNS functionality are not affected,
+      even when the DNS functionality is enabled.
+      This issue has been fixed by modifying the code to ensure that the DNS
+      Response Parser never attempts to read beyond the DNS
+      response buffer boundary.
+      We would like to thank Paschal Amusuo, James C. Davis, and
+      Aravind Machiry of Purdue University, for reporting this issue.
+    + Fixed possible freed memory being reused while creating TCP sockets.
+      We thank @htibosch  for their contribution.
+    + Fixed possible NULL pointer dereference in TCP transmission.
+      We thank @anordal for their contribution.
+    + Added network interface port for ARM Corstone-315 (MPS4_CS315).
+      We thank @david-hazi-arm for their contribution.
+    + Fixed MISRA C 2012 issues in the code
+    + Replaced the usage strcpy with strncpy
+    + Improved memory allocation failure handling in `vDNSSetCallBack` by
+      propagating error signal back. We thank @hlef for reporting this issue.
+    + Improved memory allocation failure handling in `prvCreateSectors` by
+      propagating error signal back. We thank @hlef for reporting this issue.
+    + Enabled build on CI with sanitizers, fixed all AddressSanitizer
+      and UB-Sanitizer errors. We thank @anordal for their contribution.
+    + Fixed mDNS lookups while parsing the mDNS answers.
+      We thank @htibosch for their contribution.
+    + Fixed DNS name resolution responses when the device IP address
+      is `0.0.0.0`. We thank @evpopov  for their contribution.
+    + Avoided FreeRTOS-Plus-TCP forcing to use the compilation options
+      set in the library CMake project in user projects.
+      We thank @apcountryman  for their contribution.
+    + Enabled user control of compiler analysis for non ISO statements.
+      We thank @thirtytwobits for their contribution
+    + Fixed use of removed macro in ATSAME5x network interface.
+      We thank @apcountryman  for their contribution.
+    + Fixed inconsistent use of `ipconfigCOMPATIBLE_WITH_SINGLE`
+      & `ipconfigIPv4_BACKWARD_COMPATIBLE`
+    + Resolved Unit Test Build Warnings
+    + Added network interface functions for multicast MAC address filtering.
+      We thank @evpopov for their contribution.
+    + Fixed missing `ipconfigUSE_DNS_CACHE` check in FreeRTOS_DNS.c.
+    + Avoided compiler warnings about the printf formats in IPv6 modules.
+      We thank @htibosch for their contribution.
+    + Removed deprecated macro `ipconfigMULTI_INTERFACE`.
+      We thank @HTRamsey for their contribution.
+    + Removed unused function xProcessedTCPMessage.
+      We thank @HTRamsey for their contribution.
+    + Removed deprecated macros ipLOCAL_MAC_ADDRESS and
+      `ipLOCAL_IP_ADDRESS_POINTER`. We thank @HTRamsey  for their contribution.
+    + Fixed eARPGetCacheEntryGateWay to properly report when no valid gateway is found
+      for a packet that needs to be sent outside the local network.
+      We thank @evpopov  for their contribution.
+    + Combined duplicated IPv4/IPv6 TCP code.
+      We thank @HTRamsey for their contribution.
+    + Improved validation of configuration macros in the default
+      IP config using static compile time checks.
+      We thank @HTRamsey for their contribution.
+    + Repaired ARP unit tests which were accessing packet memory
+      outside of allocated bounds.
+    + Moved CMake compile options to test builds to avoid build issues in
+      user projects that might be not be supporting compiler options used
+      in the original Cmake. We thank @apcountryman  for their contribution.
+    + Cleaned up CMake by adding: additional unit tests, incorporating missing
+      network interface support, removing unused "config files" that are no longer
+      required, and fixing file name issues in the unit testing framework.
+      We thank @HTRamsey for their contribution.
