+
+### Fixed
+- **Fix multipart delimter boundary parsing ([#502](https://github.com/apollographql/apollo-ios-dev/pull/502)):** The multipart message parsing code was not splitting message chunks at the correct boundary when the dash boundary was present in the message body.
+- **Fix Websocket error broadcast for unsubscribed ID ([#506](https://github.com/apollographql/apollo-ios-dev/pull/506))** Only broadcast an error to all subscribers if there was no id field in the message.

+- **Fix assigning websocket callback queue before connecting ([#529](https://github.com/apollographql/apollo-ios-dev/pull/529)):** Fixed a race condition with the callback queue assignment during an unstable connection.
