Invision Power Services has launched their test site for their new 4.0 software that we'll be upgrading to sometime after they release it and a new skin is available (most likely the same skin / theme we are using now). Its interesting as I didn't know what exactly to expect. I knew they were recoding the entire platform so all their products can be used separately, but I was kind of expecting some new eye popping layout or something. When compared to their current forum, it actually looks very similar:

Current forum running IPB 3:

Test forum running IPB 4:

Once a good skin is installed, I'm sure it'll look fine, just like how AC currently looks very different from the regular IPB3 skin.

It does look like some nice features have been added and the software works much better on mobile devices now, including mobile image uploads. According to their admins, they have spent a long time making the new core software to give them a solid platform to add many new features and functionality to for years to come. I look forward to seeing what this software is actually capable of. I've been holding off on doing any major renovations to this site because I've been waiting for this new version. As of this post, they have still not revealed the new content management system (CMS aka IP.Content), and that is the primary piece that I'm most interested in and how the new version of it will affect the way articles are handled on AC.
