Movable Type 4.0, the latest version of the software that runs PerlBuzz and who knows how many other blogs, was released yesterday by Six Apart, who are also responsible for TypePad, LiveJournal, and Vox -- all written in Perl.
The list of what's new is pretty long, with lots of interesting stuff on it.
Significant new features [...] are centered around community building, with first-class support for comment conversations using OpenID and user registration. The new community pack delivers a social network in a box, allowing end users to create profile pages and rate others.
Unfortunately not all of these features will be included in the forthcoming Open Source version, and it's hard to know exactly what the differences will be at this point. Byrne Reese, product manager for Movable Type, said, "Before we dive too deeply into defining the precise difference we wanted to engage the community about that." The discussion around Movable Type Open Source will occur on http://movabletype.org, the MT community site.
The Open Source version is a new step for Six Apart. Although Movable Type was free for download in its early days, the release of Movable Type 3.0 in 2004 came with a new proprietary license, requiring all but the smallest blogs to pay to use it. This engendered a great deal of controversy at the time.
In any case, the new commercial version looks pretty slick, and the administrative interface is quite a departure from earlier versions.
PerlBuzz will be upgrading to the official 4.0 release as soon as we find enough round tuits.
