Dont think there is a 'latest version'. It is burryd and forgotten.
But you can still use it. When adding a plugin to the layout, right click in the window listing the plugins. Choose the only choice given.
Also, i think it is still temporal 'there', to be backwards compatible. I will not be suprised when it is totaly gone in some nearby future version. So, using it is up to you and only up to you.
