To help you stay on top of messages in Google Chat Spaces, Google has introduced conversation summaries, which provide a helpful digest of conversations in a space, allowing you to quickly catch-up on unread messages and navigate to the most relevant threads.

Conversation summaries is enabled for your account by defaults and you will start seeing summaries in spaces that have many unread messages.

Availability

These features are now available for all UNLVMail (@unlv.edu) and Rebelmail accounts (@unlv.nevada.edu)
