+Q: Are libomptarget and plugins backward compatible?
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+No. Since libomptarget and plugins are now built as LLVM libraries starting from
+LLVM 15, they are not backward compatible. Given that fact, both libomptarget and
+plugin interfaces are not guaranteed to be compatible as well. It is always
+recommended to use the Clang compiler and runtime libraries from the same build.
+If not, it is up to users to make sure the compatibility.
