For example, you can use upd to quickly inform about changes in plans or correct a previous mistake. If you wrote: "Let's meet at 5 o'clock," and then the meeting place changed, you can add: "upd: The meeting place has changed, now near the cafe." Or if you informed that the meeting will take place tomorrow at 6, but you made a mistake, you can write: "upd: Sorry, I meant 7 o'clock."
Updates can be notified in both new and existing messages.
