Steve Palmer has posted a beta of Vienna 2.1, an open source RSS/Atom client for Mac OS X. Vienna is the first reader I've found acceptable for daily use; not great but good enough. (Of course my standards for "good enough" are pretty high.) 2.1 focuses on improving the user interface with a unified layout that lets you scroll through several articles, article filtering (e.g. read all articles since the last refresh), manual folder reordering, a new get info window, and an improved condensed layout.
Matt Mullenweg has released Wordpress 2.0.4, a blog engine based on PHP and MySQL. 2.0.4 plugs various security holes, mostly involving plugins.
