 # 2.0.0-alpha.10
 * All calls to `Service.parseId` are now affixed with the `<Id>` argument.
 * Added `uri` getter to `AngelHttp`.
+* The default for `parseQuery` now wraps query parameters in `new Map<String, dynamic>.from`.
+This resolves a bug in `package:angel_validate`.
 
 # 2.0.0-alpha.9
 * Add `Service.map`.
