From d9069388f3aa22d548b4d51c069d42bd644b7ff4 Mon Sep 17 00:00:00 2001 From: David Robertson Date: Wed, 1 Sep 2021 13:48:41 +0100 Subject: Correctly include room avatars in email notifications (#10658) Judging by the template, this was intended ages ago, but we never actually passed an avatar URL to the template. So let's provide one. Closes #1546.
