So that article talks about third party clients - third party e2ee support has gone from "basically none" to "a few clients". It's complaints for the official client is that e2ee is opt in (not anymore), fingerprints are shown base64 rather than base10 (a: who cares, b: there's an emoji encoded display now for shorter user recognisible fingerprints) and that it warns about being in beta (it isn't anymore).
