 ## Workaround List
-
-### Cronet Compression
-
-**Workaround ID:** WORKAROUND\_ID\_CRONET\_COMPRESSION
-
-**Date added:** May 06, 2017
-
-**Status:** Implemented in C core and C++
-
-**Issue:** Before version v1.3.0-dev, gRPC iOS client's Cronet transport did not implement compression. However the clients still claim to support compression. As a result, a client fails to parse received message when the message is compressed.
-The problem above was resolved in gRPC v1.3.0-dev. For backward compatibility, a server must forcingly disable compression for gRPC clients of version lower than or equal to v1.3.0-dev.
-
-**Workaround Description:** Implemented as a server channel filter in C core.  The filter identifies the version of peer client with incoming `user-agent` header of each call. If the client's gRPC version is lower that or equal to v1.3.x, a flag GRPC_WRITE_NO_COMPRESS is marked for all send_message ops which prevents compression of the messages to be sent out.
