 There are no changes to the behavior of the editor context. When the active editor has a selection, then just the selection is included. Otherwise, just the code that is scrolled into view is included. You can still attach other files or the full file by using the paperclip button or by typing `#` in the chat prompt.

 The follow-up prompts suggested by Chat are now more concise and only appear on the first turn to make room for the conversation.

+### Automatic chat participant detection
+
+GitHub Copilot has several built-in chat participants, such as `@workspace`, and you may have installed other extensions that contribute chat participants too.
+
+To make it easier to use chat participants with natural language, Copilot Chat will automatically route your question to a suitable participant or chat command, when possible.
+
+If the automatically selected participant is not appropriate for your question, you can still select the **rerun without** link at the top of the chat response to resend your question to Copilot.

+
+This month, we also added a command to let you skip this behavior on a per-request basis. "Send and dispatch" is the default command run when pressing "enter". "Send" will just send the request directly to Copilot Chat, and it won't be automatically dispatched to a chat participant.
