Version 2.64 of Movable Type is now released. This is a maintenance release, fixing various CSS, XML-RPC, UI, and Creative Commons errors. This release also plugs a number of cross-site-scripting (script injection) holes for search queries, comments, TrackBacks, and notifications, and is recommended for anyone using any of these features. We have also improved the options for available RSS templates--in addition to the RSS 1.0 template that we have always provided, the default templates now include an RSS 2.0 template instead of a 0.91 template. Also in the default templates, this release fixes the rendering of the default stylesheet ("Clean") on Windows Internet Explorer. The full changelog lists the changes and fixes in 2.64.

If you hadn't yet upgraded to 2.6, see the Guide to Movable Type 2.6 for explanations of the above features, and for instructions on adding these features to your existing weblog if you are upgrading.

If you're upgrading from any previous Movable Type release, use the upgrade instructions. If you're installing this release for the first time, use the installation instructions.

The New York Times has a couple of fun articles on weblogs this weekend, chock full of good information on the social implications of weblogs and featuring a number of great sites that are powered by Movable Type.

"Dating a Blogger, Reading All About It" features MT users like Heather Armstrong and Jonathan Van Gieson talking about the trials and tribulations of living life in public via a website, along with some cogent quotes by David Weinberger and Nick Denton. And "A New York State of Blog" focuses on a subject that's near and dear to my heart, blogging culture in New York City. Jonathan and Nick are featured again, along with Gawker's Liz Spiers, a link to Gothamist, run by Jen Chung and Jake Dobkin, and a nice mention of Lockhart Steele.

It's good to see all of these sites get this much-deserved attention, and it just makes sense that Movable Type sites would get featured in a section called "Fashion & Style".

Those of you who checked out the Screen Savers today got a good look at how easy it is to change style sheets on your Movable Type weblog right within the interface. While Sarah had some good ideas on how to do this, we don't recommend just taking someone else's stylesheets. Feel free to learn from them, but make sure you modify them or create your own.

Not only will the original creator appreciate not having their design borrowed (designs are copyrighted by default), you'll benefit my making sure your design is as distinctive as your writing. And in the meantime, we're working on making it even easier to design and share your stylesheets in Movable Type.
