"Other than departmentalizing the Weblog functionality, the major addition is the integration and rewrite of Xhoo. In short, this version of Weblog is a move towards a well-defined environment for creating, editing, syndicating, and organizing channels. ... If you haven't heard of it before, Xhoo is a Web catalog that I developed as an article a while back. You can still read about it off the Mother of Perl home page. The difference now is that Xhoo itself is built using RSS files, which allows you to leverage all of the same tools that are now available for manipulating RSS. In the future, Xhoo will probably support the RSS 1.0 threads module as soon as it matures a bit. Weblog channels link to Xhoo categories through the taxonomy RSS 1.0 module."
