A new version of Rialto is available in the download section of the site corresponding to the 0.9 release:
* bug corection
* the tabFolder has a new parameter call orientation that allow to set the orientation of the tabitem with `t’ for top, `l’ for left, `r’ for right and `b’ for bottom position.
* integration of firebug lite for debug. If you have the firebug plugin in FF then all the messages will be display in. Else (IE or FF without firebug) an emulation of the console appear in a floating frame in your page. I already talk about it here
* the grid become skinable
Notice that the next version will be the V1. We plan to release it in september.
