Stable release of Tapspace 1.6.0. Tapspace 1.x versions will be maintained but probably not actively developed in order to focus on Tapspace 2.x.
The main difference is that Tapspace 1.x implements a virtual scene tree that is rendered into HTML. Tapspace 2.x handles DOM directly.
While Tapspace v1 is purely 2D, Tapspace v2 provides both 2D and 3D features.
