Hi everyone,
This is really news from a week ago, but there's a new version out of the Semantic Bundle, that now includes the latest stable version of Semantic MediaWiki, 1.9.2, as well as updated versions of most of its other extensions. It took a little while to "iron all the kinks out", as well as to make sure that the package fully works for people across different systems, but now everything seems to be fine.
About Semantic Bundle: it's a package of over 25 extensions and libraries, that includes SMW and extensions that are typically used in conjunction with it.
