@@ -23,6 +23,7 @@ Enhancements
 * `EvalAltResult::IndexNotFound` is added to aid in raising errors for indexers.
 * `Engine::def_tag`, `Engine::def_tag_mut` and `Engine::set_tag` are added to manage a default value for the custom evaluation state, accessible via `EvalState::tag()` (which is the same as `NativeCallContext::tag()`).
 * Originally, the debugger's custom state uses the same state as `EvalState::tag()` (which is the same as `NativeCallContext::tag()`).  It is now split into its own variable accessible under `Debugger::state()`.
+* Non-borrowed string keys can now be deserialized for object maps via `serde`.
