This includes some nifty code from me that required a database upgrade (content items can now be featured on one section while displayed as regular content on another–and the system can be expanded to define other “publishing modes” beyond regular and featured), hence the .1 version number.
Oscar also sped up things significantly, particularly in the admin tool. There are also some further refinements to permissions. They’re reflected all over the admin tool–datatype-level and object-level.
Of course, I found a couple of bugs today right after the release, so at some point soon I’ll have those in CVS for the .1 release. However, they’re not really show-stoppers.
