We're cleaning up some lingering behavior in our legacy Real Time Messaging API. In message events streamed over the RTM API, channel and usergroup mentions will no longer include entity names. Still need entity names? Access them using Web API methods such as conversation.info and usergroups.list. Alternatively, consider using the Events API, which also supports WebSockets, to receive message events.
