-## [1.0.3] - Bug fixes
+# Changelog
+## 1.0.4
+### Implemented Fallback Request
+
+- [Added] You can now worry less about retry action action on failure, as it just do it for you. In order to guarantee a very high availability, we implemented recommended retry strategy for all API calls on all your read and write actions. (Currently, fallback request is not supported for insight.)
+- [Added] `AlgoliaSynonymsReference` now easily set synonyms with just few lines of code
+  ```dart
+    // single
+    algolia.index('contacts').synonyms.save(AlgoliaSynonyms(
+      objectID: '1',
+      type: SynonymsType.synonym,
+      synonyms: ['iphne', 'iphone', 'ipone'],
+      forwardToReplicas: true,
+    ));
+    
+    // batch
+    algolia.index('contacts').synonyms.batch([
+      AlgoliaSynonyms(
+        objectID: '1',
+        type: SynonymsType.synonym,
+        synonyms: ['iphne', 'iphone', 'ipone'],
+        forwardToReplicas: true,
