The big one has landed: mesh-based rendering. This is the main reason for the major version bump and it is fully working now. Mesh-based rendering means that instead of drawing lines using the low-level GL class a mesh is generated which Unity can then render the same way it renders any other mesh. This means that grid lines can now be rendered below sprites instead of always on top of them.
Grid Framework version 3.0 is coming along nicely, I have reached feature parity with the previous major release. This means that the heavy refactoring is mostly done and I can now build upon that foundation. I want to take this opportunity to reflect on what will change.
I intend to release a new major update which will address among other things the grid rendering system. It has been almost five years since the release of version 2.0, and Unity has changed quite a lot in this time. Some of those changes, in particular the introduction of sprites, need to be accounted for in Grid Framework.
