There is no need to use this version any more as most of the good changes are now in SVN.
You cannot choose where to get your covers from with the new SVN version, but it does have an auto update csscript facility with central store + update grabbers.
I am sure the remainder of the features you all like from this test build will make it into the core at some point, but at the moment we are thinking more like version 1.0.1 just we can get 1.0 as stable as possible.
If you want to start using the latest svn and make your changes to that version we can get them released to all.
