+- A warning was added about usage of embind without C++17 or above. (#25424)
 - The minimum supported versions of Node, Chrome and Firefox were bumped
   enabling the removal of the `globalThis` polyfill and universally enabling
   mutable globals: (#25375, #25385)
   - Node: v10.19.0 -> v12.22.9

   - Firefox: v55 -> v65
+- The Embind `val` functions `call`, `operator()`, and `new_` now support
+  passing `pointer`s by using the `allow_raw_pointers()` argument. This feature
+  is only enabled with C++17 and newer. Older versions will allow pointers by
