+    `X API`
+
+    Today, we made a change to X API V2 DM Events behavior. With the new change participant_ids array will only be included for ParticipantsJoin and ParticipantsLeave events, and it will list only the participants who joined or left at the time of the event. The MessageCreate event will no longer include the participant_ids array. Learn more [here](https://devcommunity.x.com/t/upcoming-change-to-x-api-dm-events-endpoints-behavior/241841).
