Leaflet Changelog

(all changes without author notice are by @mourner)

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 for a big part of this work.
• Added layers control (Control.Layers) for convenient layer switching.
• Added ability to set max bounds within which users can pan/zoom. #93

Improvements

Usability improvements

• 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
• Limited maximum zoom change on a single mouse wheel movement (so you won't zoom across the whole zoom range in one scroll). #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

• Added ability to add a tile layer below all others (map.addLayer(layer, true)) (useful for switching base tile layers).
• Added Map zoomstart event (thanks to @Fabiz). #377
• Improved Map locate method, added ability to watch location continuously and more options. #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
• 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). #256
• Added TileLayer zoomOffset option useful for non-256px tiles (by @msaspence).
• Added TileLayer.Canvas redraw method (by @mortenbekditlevsen). #459
• Added Polyline closestLayerPoint method that's can be useful for interaction features (by @anru). #186
• Added setLatLngs method to MultiPolyline and MultiPolygon (by @anru). #194
• Added getBounds method to Polyline and Polygon (by @JasonSanford). #253
• Added FeatureGroup setStyle method (also inherited by MultiPolyline and MultiPolygon). #353
• Added FeatureGroup invoke method to call a particular method on all layers of the group with the given arguments.
• Added ImageOverlay load event. #213
• Added minWidth option to Popup (by @marphi). #214
• Improved LatLng constructor to be more tolerant (and throw descriptive error if latitude or longitude can't be interpreted as a number). #136
• Added LatLng distanceTo method (great circle distance) (by @mortenbekditlevsen). #462
• Added LatLngBounds toBBoxString method for convenience (by @JasonSanford). #263
• Added LatLngBounds intersects(otherBounds) method (thanks to @pagameba). #350
• Added Bounds intersects(otherBounds) method. #461
• Added L.Util.template method for simple string template evaluation.
• Added DomUtil.removeClass method (by @anru).
• Added ability to pass empty imageUrl to icons for creating transparent clickable regions (by @mortenbekditlevsen). #460
• 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). #179
