Version 1.2 of XEP-0184 (Message Delivery Receipts) has been released. Abstract: This specification defines an XMPP protocol extension for message delivery receipts, whereby the sender of a message can request notification that the message has been delivered to a client controlled by the intended recipient.
Changelog: Clarified terminology and several points of implementation; explicitly stated that this protocol notifies the sender only that a message has been delivered to a client, not that it has been read or understood by a human user (if any); changed title from Message Receipts to Message Delivery Receipts to make this 100% clear.
