  * Map now preserves its center after resize.
  * When panning to another copy of the world (that's infinite horizontally), map overlays now jump to corresponding positions. [#273](https://github.com/CloudMade/Leaflet/issues/273)
  * Limited maximum zoom change on a single mouse wheel movement (so you won't zoom across the whole zoom range in one scroll). [#149](https://github.com/CloudMade/Leaflet/issues/149)
+ * Significantly improved line simplification performance (noticeable when rendering polylines/polygons with tens of thousands of points)
  * Improved circles performance by not drawing them if they're off the clip region.
 
 #### API improvements

  * Improved `Map` `locate` method, added ability to watch location continuously and more options. [#212](https://github.com/CloudMade/Leaflet/issues/212)
  * Added second argument `inside` to `Map` `getBoundsZoom` method that allows you to get appropriate zoom for the view to fit *inside* the given bounds.
  * Added `hasLayer` method to `Map`.
+ * Added `Marker` `zIndexOffset` option to be able to set certain markers below/above others. [#65](https://github.com/CloudMade/Leaflet/issues/65)
  * Added `urlParams` third optional argument to `TileLayer` constructor for convenience: an object with properties that will be evaluated in the URL template.
  * Added `TileLayer` `continuousWorld` option to disable tile coordinates checking/wrapping.
  * Added `TileLayer` `tileunload` event fired when tile gets removed after panning (by [@CodeJosch](https://github.com/CodeJosch)). [#256](https://github.com/CloudMade/Leaflet/pull/256)
  * Added `TileLayer` `zoomOffset` option useful for non-256px tiles (by [@msaspence](https://github.com/msaspence)).

  * Improved superclass access mechanism to work with inheritance chains of 3 or more classes; now you should use `Klass.superclass` instead of `this.superclass` (by [@anru](https://github.com/anru)). [#179](https://github.com/CloudMade/Leaflet/pull/179)
 
+#### Development workflow improvements
