 3.1.35 (in development)
 -----------------------
+- The following JavaScript runtime functions were converted to JavaScript
+  library functions:
+   - UTF8ArrayToString
+   - UTF8ToString
+   - stringToUTF8Array
+   - stringToUTF8
+   - lengthBytesUTF8
+  If you use any of these functions in your JS code you will now need to include
+  them explictly in one of the following ways:
+   - Add them to a `__deps` entry your JS library file ((with leading $)
+   - Add them to `DEFAULT_LIBRARY_FUNCS_TO_INCLUDE` (with leading $)
+   - Add them to `EXPORTED_FUNCTIONS` (without leading $)
+   - Set `-sLEGACY_RUNTIME` to include all of them at once.
 - `allocateUTF8` and `allocateUTF8OnStack` library function moved to
   `library_legacy.js`.  Prefer the more accurately named `stringToNewUTF8` and
   `stringToNewUTF8OnStack`. (#19089)
