I was curious why Leaflet, which has been around a while, popped up today. Looks like it's because 1.3.0 is out, but as far as I can tell it's a bugfix release. The most exciting new feature (to me, at least) is iterating over layers in a LayerGroup with eachLayer, which is neat but hardly groundbreaking.<p>Am I missing something? I love Leaflet, but I thought it was already one of the standards for maps on the web.
