Hi Imran,
It is the new “unstable” version of Corona plugin and not the update of Beta 1. This is the reason why it is called Beta 2, but it is of course based on Beta 1. Beta 1 is current “stable” version and it will be the most actual stable version until Beta 2 stable version is released. The first two features which we managed to finish from the roadmap are “Skin material” and “Material preview responsiveness” other features implementation is in progress, but I still have to update the roadmap. If you started some job in Beta 1 we recommend to finish it in Beta 1 because Beta 2 is in daily builds phase so it can be quite unstable.
