LJ pushed release 99 yesterday. Tucked away in the Russian release notes
(link goes to translation/summary, not to official comm) is an announcement about a new style, Chameleon
. The standard themes include a sidebar and no-sidebar version & two different unstyled versions (I'm not sure on the difference between them.) The layer info is available here
On first glance it seems like a nice combination of the better bits of Expressive and Minimalism. When I get a chance to delve deeper into the CSS I might end up switching to this.
