Sockethub 4.0.0 has been released! This release has a few major updates to the underlying system, namely switching from node-simple-xmpp to xmpp.js, from Kue to Bull and upgrading to v4. Additionally, as we performed these significant overhauls of the code, we added more tests and optimizations. This release should be overall a lot faster. For a full list of changes, see the Sockethub release page.
