Hell yeah! Numerous additions, sleeko-neato functionality, two bugs swatted and some feature cuts, including but not restricted to:

• XR::RenderRegion - calculates the world coordinates of the current viewport's four sides, based on XR::Camera2D's current viewer and layer, so you don't have to.
• XR::Indexer2D - takes the weight of managing 1D array represented 2D arrays, off your shoulder. Includes conversion to and from indices, coordinates' and range validation.
• Optimisation and flexibilisation in XR::Texture2D::Capture() and XR::Texture2D::Generate<>() - use shorthand generation with colorkeys!
• XR::DrawArrow() for customizable yet optimal arrow drawing.
• XR::KeyPositiveEdge() and XR::KeyNegativeEdge() to more conveniently check for just pressed / released keys.
• Well, I did pull the plug on XR::Table<> and XR::GridHasher<> in the process, but you've got XR::Indexer2D in lieu of the earlier, and I'll come up with something neater in lieu of the latter.

You'll need to wait a couple of hours for the OS X version, but I hope you'll agree with me that it'll be worth it. Check the docs in the meantime!
