ELGG have upgraded to version 0.4 today. There is a new (mediawiki) Elgg Information portal and a new company: Curverider offering hosting, training etc

This what’s new according their Press Release

With version 0.4, podcasting is as easy as pushing a button. An advanced templating engine uses CSS
standards to allow the user full control over the look and feel of their digital assets. Users can link to
content on the Web as easily as writing a note, and search for related information – as well as people
working on the same topics they are – simply by clicking a link. Information can be drawn into a user’s
profile using the power of RSS. Shared calendars can list classes, promote events or let users keep
track of their appointments. Files, reflections, podcasts, blog posts and profile information can all be
shared with as many or as few people as the owner desires.
