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

(all changes without author notice are by [@mourner](https://github.com/mourner))

## 0.7 (master)

An in-progress version being developed on the master branch.

 * Fixed a bug where zoom buttons inherited Bootstrap link hover styles. [#1791](https://github.com/Leaflet/Leaflet/issues/1791)
 * Fixed a bug with broken zooming on maps with EPSG3395 projection. [#1796](https://github.com/Leaflet/Leaflet/issues/1796)

## 0.6 (June 26, 2013)

### Breaking changes

 * Moved polyline editing code into [Leaflet.draw](https://github.com/Leaflet/Leaflet.draw) plugin (where it fits much better along with all other editing and drawing handlers). The API remains the same.
 * Dropped support for environments that augment `Object.prototype` (luckily it's a thing of the past nowadays).

### Improvements

#### Usability and performance improvements

 * **Improved zoom control design** - cleaner, simpler, more accessible (mostly by [@jacobtoye](https://github.com/jacobtoye)). [#1313](https://github.com/Leaflet/Leaflet/issues/1313)
 * Updated `Control.Layers` icon (designed by Volker Kinkelin), added retina version and SVG source. [#1739](https://github.com/Leaflet/Leaflet/issues/1739)
 * Added keyboard accessibility to markers (you can now tab to them and press enter for click behavior). [#1355](https://github.com/Leaflet/Leaflet/issues/1355)
 * Improved `TileLayer` zoom animation to eliminate flickering in case one tile layer on top of another or when zooming several times quickly (by [@mourner](https://github.com/mourner) with lots of fixes from [@danzel](https://github.com/danzel)).

 * Subtly improved default popup styles
 * Improved attribution control to be much less obtrusive (no "powered by", just a Leaflet link). You can still remove the prefix with `map.attributionControl.setPrefix('')` if you need.
 * Improved zoom behavior so that there's no drift of coordinates when you change zoom back and forth without panning. [#426](https://github.com/Leaflet/Leaflet/issues/426)

## 0.5 (January 17, 2013)

### Breaking changes

Be sure to read through these changes to avoid any issues when upgrading from older versions:

 * Removed default `LatLng` wrapping/clamping of coordinates (`-180, -90` to `180, 90`), wrapping moved to an explicit method (`LatLng` `wrap`).
 * Disabled `Map` `worldCopyJump` option by default (jumping back to the original world copy when panning out of it). Enable it explicitly if you need it.
 * Changed styles for the zoom control (you may need to update your custom styles for it).

## 0.4.4 (August 7, 2012)

### Improvements

 * Improved `GeoJSON` `setStyle` to also accept function (like the corresponding option).
 * Added `GeoJSON` `resetStyle(layer)`, useful for resetting hover state.
 * Added `feature` property to layers created with `GeoJSON` (containing the GeoJSON feature data).

## 0.4 (July 30, 2012)

### API simplification

Leaflet 0.4 contains several API improvements that allow simpler, jQuery-like syntax ([example](https://gist.github.com/3038879)) while being backwards compatible with the previous approach (so you can use both styles):

 * Improved most methods and options to accept `LatLng`, `LatLngBounds`, `Point` and `Bounds` values in an array form (e.g. `map.panTo([lat, lng])` will be the same as `map.panTo(new L.LatLng(lat, lng))`)
 * Added `addTo` method to all layer classes, e.g. `marker.addTo(map)` is equivalent to `map.addLayer(marker)`
 * Added factory methods to most classes to be able to write code without `new` keyword, named the same as classes but starting with a lowercase letter, e.g. `L.map('map')` is the same as `new L.Map('map')`

### Notable new features

 * Added configurable **panning inertia** - after a quick pan, the map slows down in the same direction.
 * Added **keyboard navigation** for panning/zooming with keyboard arrows and +/- keys (by [@ericmmartinez](https://github.com/ericmmartinez)). [#663](https://github.com/Leaflet/Leaflet/pull/663) [#646](https://github.com/Leaflet/Leaflet/issues/646)
 * Added smooth **zoom animation of markers, vector layers, image overlays and popups** (by [@danzel](https://github.com/danzel)). [#740](https://github.com/Leaflet/Leaflet/pull/740) [#758](https://github.com/Leaflet/Leaflet/issues/758)
 * Added **Android 4+ pinch-zoom** support (by [@danzel](https://github.com/danzel)). [#774](https://github.com/Leaflet/Leaflet/pull/774)
 * Added **polyline and polygon editing**. [#174](https://github.com/Leaflet/Leaflet/issues/174)
 * Added an unobtrusive **scale control**.
 * Added **DivIcon** class that easily allows you to create lightweight div-based markers.
 * Added **Rectangle** vector layer (by [@JasonSanford](https://github.com/JasonSanford)). [#504](https://github.com/Leaflet/Leaflet/pull/504)

### Improvements

#### Usability improvements

 * Improved zooming so that you don't get a blank map when you zoom in or out twice quickly (by [@danzel](https://github.com/danzel)). [#7](https://github.com/Leaflet/Leaflet/issues/7) [#729](https://github.com/Leaflet/Leaflet/pull/729)
 * Drag-panning now works even when there are markers in the starting point (helps on maps with lots of markers). [#506](https://github.com/Leaflet/Leaflet/issues/506)
 * Improved panning performance even more (there are no wasted frames now).
 * Improved pinch-zoom performance in mobile Chrome and Firefox.
 * Improved map performance on window resize.
 * Replaced box-shadow with border on controls for mobile devices to improve performance.
 * Slightly improved default popup styling.
 * Added `TileLayer` `detectRetina` option (`false` by default) that makes tiles show in a higher resolution on iOS retina displays (by [@Mithgol](https://github.com/Mithgol)). [#586](https://github.com/Leaflet/Leaflet/pull/586)

#### GeoJSON API changes

GeoJSON API was improved to be simpler and more flexible ([example](https://gist.github.com/3062900)). The changes are not backwards-compatible, so be sure to update your old code.

 * Added `style` option for styling vector layers, passed either as an object or as a function (to style vector layers according to GeoJSON properties).
 * Added `filter` option to leave out features that don't correspond to a certain criteria (e.g. based on properties).
 * Added `onEachFeature` option to execute certain code on each feature layer based on its properties (binding popups, etc).
 * Changed `pointToLayer` function signature to provide `geojson` in addition to `latlng` when creating point features for more flexibility.

#### Icon API changes

Icon API was improved to be more flexible, but one of the changes is backwards-incompatible: you now need to pass different icon properties (like `iconUrl`) inside an options object ([example](https://gist.github.com/3076084)).

 * Converted `Icon` properties to options, changed constructor signature to `Icon(options)`.
 * Moved default marker icon options to `L.Icon.Default` class (which extends from `L.Icon`).
 * Added `Icon` `className` option to assign a custom class to an icon.
 * Added `Icon` `shadowAnchor` option to set the anchor of the shadow.
 * Made all `Icon` options except `iconUrl` optional (if not specified, they'll be chosen automatically or implemented using CSS). Anchor is centered by default (if size is specified), and otherwise can be set through CSS using negative margins.

#### Control API changes

 * Added `setPosition` and `getPosition` to all controls, as well as ability to pass certain position as an option when creating a control.
 * Made controls implementation easier (now more magic happens under the hood).
 * Replaced ugly control position constants (e.g. `L.Control.Position.TOP_LEFT`) with light strings (`'topleft'`, `'bottomright'`, etc.)

#### Other breaking API changes

 * Improved `TileLayer` constructor to interpolate URL template values from options (removed third `urlParams` argument).
 * Changed `TileLayer` `scheme: 'tms'` option to `tms: true`.
 * Removed `Map` `locateAndSetView` method (use `locate` with `setView: true` option)
 * Changed popup `minWidth` and `maxWidth` options to be applied to content element, not the whole popup.
 * Moved `prefix` argument to `options` in `Control.Attribution` constructor.
 * Renamed `L.VERSION` to `L.version`.

## 0.3 (February 13, 2012)

### 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.
