The main topic is probably the change of Riot to Element.
This week was the announcement of the much-awaited rebrand: Riot is now Element. In fact, three brands are coalescing into one: Riot and New Vector will be referred to as Element, while the SaaS platform known as Modular.im is now Element Matrix Services.
Note that Matrix is not involved in this change. Matrix is still Matrix, don't worry about that!
