   * Applications that did set `HAVE_CPP_STDLIB` before, need to set
     `OPENTELEMETRY_STL_VERSION=<version>` instead, to build with a
     specific STL version (2011, 2014, 2017, 2020, 2023).
+  * The opentrelemetry-cpp makefile no longer sets
+    CMAKE_CXX_STANDARD by itself.
+    Instead, the CMAKE_CXX_STANDARD and/or compiler options -stdc++ used
+    by the caller are honored.
+  * Applications that set neither CMAKE_CXX_STANDARD nor -stdc++
+    options may need to provide a C++ standard in their makefiles.
