 This section lists changes that do not have deprecation warnings.
 
+  * Keyword arguments are now `NamedTuple`s rather than `Iterators.IndexValue`s. This
+    is breaking because iteration over `NamedTuple`s produces values only, whereas iteration
+    over `Iterators.IndexValue` produces name, value pairs. The `pairs` function can be
+    used to extract both names and values. ([#24795])
+
   * `readuntil` now does *not* include the delimiter in its result, matching the
     behavior of `readline`. Pass `keep=true` to get the old behavior ([#25633]).
