+v1.1.7 (2021-04-04)
+================================================================================
+
+- __FIX__: with the phpiredis-based connection backends, failed pipelines led to
+spurious responses returned after reconnecting to Redis because the underlying
+reader was not properly reset by discarding buffered replies after disconnecting
+(ISSUE #363).
+- __FIX__: removed `cweagans/composer-patches` dev dependency and apply patches
+using `post-update-cmd` script.
