Leaflet Changelog
=================

## 0.3 (master)

### Major features

 * Added **Canvas backend** for vector layers (polylines, polygons, circles). This enables vector support on Android < 3, and it can also be optionally preferred over SVG for a performance gain in some cases. Thanks to [@florianf](https://github.com/florianf) for a big part of this work.
 * Added **layers control** (`Control.Layers`) for convenient layer switching.

### Improvements

#### Usability improvements

 * 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)
 * Improved circles performance by not drawing them if they're off the clip region.  

#### API improvements

 * Improved `LatLng` constructor to be more tolerant (and throw descriptive error if latitude or longitude can't be interpreted as a number). [#136](https://github.com/CloudMade/Leaflet/issues/136)
 * Improved browser-specific code to rely more on feature detection rather than user agent string.
 * 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)
 * Added ability to add a tile layer below all others (`map.addLayer(layer, true)`) (useful for switching base tile layers).
 * Added `hasLayer` method to `Map`.
 * Added `Polyline` `closestLayerPoint` method that's can be useful for interaction features (by [@anru](https://github.com/anru)). [#186](https://github.com/CloudMade/Leaflet/pull/186)
 * Added `setLatLngs` method to `MultiPolyline` and `MultiPolygon` (by [@anru](https://github.com/anru)). [#194](https://github.com/CloudMade/Leaflet/pull/194) 
 * Added `DomUtil.removeClass` method (by [@anru](https://github.com/anru)).

 * Fixed a bug where drag event fired before the actual movement of layer (by [@anru](https://github.com/anru)). [#197](https://github.com/CloudMade/Leaflet/pull/197)
 * Fixed a bug where map click caused an error if dragging is initially disabled. [#196](https://github.com/CloudMade/Leaflet/issues/196)
 * Fixed a bug where attribution prefix would not update on `setPrefix`. [#195](https://github.com/CloudMade/Leaflet/issues/195)

 * Fixed regression that caused error in `TileLayer.Canvas`.

## 0.2 (2011-06-17)

### Major features

 * Added **WMS** support (`TileLayer.WMS` layer).
 * Added different **projections** support, having `EPSG:3857`, `EPSG:4326` and `EPSG:3395` out of the box (through `crs` option in `Map`). Thanks to [@Miroff](https://github.com/Miroff) & [@Komzpa](https://github.com/Komzpa) for great advice and explanation regarding this.
 * Added **GeoJSON** layer support.
 
### Improvements
 
#### Usability improvements
 
 * Improved panning performance in Chrome and FF considerably with the help of `requestAnimationFrame`. [#130](https://github.com/CloudMade/Leaflet/issues/130)
 * Improved click responsiveness in mobile WebKit (now it happens without delay). [#26](https://github.com/CloudMade/Leaflet/issues/26)
 * Added tap tolerance (so click happens even if you moved your finger slighly when tapping).
 * Improved geolocation error handling: better error messages, explicit timeout, set world view on locateAndSetView failure. [#61](https://github.com/CloudMade/Leaflet/issues/61)
 
#### API improvements

 * Added **MultiPolyline** and **MultiPolygon** layers. [#77](https://github.com/CloudMade/Leaflet/issues/77) 
 * Added **LayerGroup** and **FeatureGroup** layers for grouping other layers.
 * Added **TileLayer.Canvas** for easy creation of canvas-based tile layers.
 * Changed `Circle` to be zoom-dependent (with radius in meters); circle of a permanent size is now called `CircleMarker`.
 * Added `mouseover` and `mouseout` events to map, markers and paths; added map `mousemove` event.
 * Added `setLatLngs`, `spliceLatLngs`, `addLatLng`, `getLatLngs` methods to polylines and polygons.
 * Added `setLatLng` and `setRadius` methods to `Circle` and `CircleMarker`.
 * Improved `LatLngBounds contains` method to accept `LatLng` in addition to `LatLngBounds`, the same for `Bounds contains` and `Point` 
 * Improved `LatLngBounds` & `Bounds` to allow their instantiation without arguments (by [@snc](https://github.com/snc)).
 * Added TMS tile numbering support through `TileLayer` `scheme: 'tms'` option (by [@tmcw](https://github.com/tmcw)).
 * Added `TileLayer` `noWrap` option to disable wrapping `x` tile coordinate (by [@jasondavies](https://github.com/jasondavies)).

 * Added `setLatLng` and `setIcon` methods to `Marker`.
 * Added `title` option to `Marker`.

#### Development workflow improvements
 
 * Added `Makefile` for building `leaflet.js` on non-Windows machines (by [@tmcw](https://github.com/tmcw)).
