From 14fe971183e5a281525827c8135965f57e15f73b Mon Sep 17 00:00:00 2001 From: Emmanuel Gil Peyrot Date: Tue, 12 Nov 2019 12:17:42 +0100 Subject: =?UTF-8?q?Don=E2=80=99t=20treat=20presence=20updates=20as=20MUC?= =?UTF-8?q?=20joins?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the user sends a directed presence to an unjoined MUC without a element, send a presence error back instead of attempting to join it again, as this is almost never what the user wants.
