Yes, but it's getting close to version 1.0 now, with an update build being released every two weeks. (sometimes quicker)
Also this Spriter 2 executable automatically looks for and downloads updates.
Still though, Spriter 2 is not quite fully stable yet and more importantly the UI is still incomplete and there is not yet any documentation or tutorials, so it's not ready for use in real projects yet, and it's likely best to wait until an upcoming update build which will at least start to supply the basic info to allow people to quickly get started using/testing it.
