There was a lot of work put into Tiled over this past summer which we'll be seeing in the upcoming Tiled 1.1 release (which is currently in beta).

Tiled2Unity version 1.0.13.0 supports two of the most important features that are coming our way: Infinite Maps and Templates.

Infinite Maps is a great addition for Unity games employing larger maps. These maps are broken down for you, automatically, into smaller chunks. These chunks will work with Unity's frustrum culling so you'll now only be rendering parts of your map that actually visible to the player. This is a good optimization we'll be get getting for free as a side-effect of the infinite maps feature.

Templates are very useful for populating your map with objects (like sprites, for instance) without having to edit every property on every object individually.  This is my favorite new feature to Tiled so I was happy to add support for it to Tiled2Unity!

This was, of course, a big change to the Tiled2Unity codebase so please let me know if you're running into any bugs or problems.
