## 1.0-beta1 (July 14, 2015)

The first beta of the huge, long-awaited Leaflet 1.0 release.

This version contains a lot of beneficial but potentially breaking changes (especially if you're a plugin author), so please read through the changes carefully if your code breaks after upgrading.

### Vectors API improvements

Leaflet vector layers rendering got a major rewrite, making it possible to switch between rendering backends (Canvas, SVG) dynamically (and even use both for different layers at the same time), have more than one physical pane for vector layers, significantly improving performance, adding Canvas retina support, getting rid of ugly hacks and generally making the code much cleaner. Main PR [#2290](https://github.com/Leaflet/Leaflet/pull/2290).

* Added `Renderer` layer (inherited by SVG/Canvas implementations) that handles renderer bounds and zoom animation.
* Added `SVG` & `Canvas` classes that now contain all renderer-specific code for vector layers and can be added as layers to the map.
* All vector layer classes (`Path`, `Polyline`, etc.) now don't contain any renderer-specific code and instead can be passed a renderer layer to use as `renderer` in options;
* Removed `MultiPolyline` and `MultiPolygon` classes since multiple rings are now handled by `Polyline` and `Polygon` classes respectively. Layers with multiple rings now perform much better (since each is now physically a single path object instead of being a `FeatureGroup` of layers).
* **Dramatically improved performance of interactive Canvas layers**. Mouse events work much faster (due to improved hit detection algorithms), and layers get updated many times faster (with partial redraws instead of redrawing the whole Canvas).
* **Dramatically improved performance of interactive SVG layers** (e.g. creating a big GeoJSON layer and adding to a map got 3x faster while taking 2.5x less memory). [#2240](https://github.com/Leaflet/Leaflet/issues/2240) [#2315](https://github.com/Leaflet/Leaflet/issues/2315)
* Added retina support for Canvas layers.
* Improved default vector layer styles.
* Added `Polyline` and `Polygon` `getCenter` for getting centroids.
* Respectively, improved `Polyline` and `Polygon` popup positioning when calling `openPopup`.
* Improved `Polyline`/`Polygon` `getBounds` to be cached (so it works much faster).
* Changed `Circle` to inherit from `CircleMarker` and not the other way.
* Fixed `GeoJSON` `resetStyle` to work properly in case `style` option wasn't set.
* Fixed a bug where map fired `moveend` when updating Canvas layers.
* Removed `Polyline` and `Polygon` `spliceLatLngs` method (just use `setLatLngs` instead).
* Changed `Polygon` `getLatLngs` to always return an array of rings (nested array) (by [@yohanboniface](https://github.com/yohanboniface)). [#2618](https://github.com/Leaflet/Leaflet/issues/2618) [#3386](https://github.com/Leaflet/Leaflet/pull/3386) [Leaflet/Leaflet#3279](https://github.com/Leaflet/Leaflet/pull/3279) [#2648](https://github.com/Leaflet/Leaflet/issues/2648)
* Added the ability to specify a custom pane for vector layers (making it possible to easily do stacks like vectors-tiles-vectors with proper z-index order) (by [@Jakobud](https://github.com/Jakobud)). [#3266](https://github.com/Leaflet/Leaflet/pull/3266) [#2786](https://github.com/Leaflet/Leaflet/pull/2786)
* Added vector layers `fillRule` option (by [@bullgare](https://github.com/bullgare)). [#2834](https://github.com/Leaflet/Leaflet/pull/2834)
* Removed `L_PREFER_CANVAS` global switch and added `Map` `preferCanvas` option instead (by [@yohanboniface](https://github.com/yohanboniface)). [#3623](https://github.com/Leaflet/Leaflet/pull/3623)

### Layers API improvements

All Leaflet layers (including markers, popups, tile and vector layers) have been refactored to have a common parent, `Layer` class, that shares the basic logic of adding and removing. The leads to the following changes (main PR [#2266](https://github.com/Leaflet/Leaflet/pull/2266)):

* Added `Layer` class which all layers added to a map should inherit from.
* Added `add` and `remove` events to all layers.
* Added `remove` method to layers and controls (`marker.remove()` is now equivalent to `map.removeLayer(marker)`).
* Improved performance of adding and removing layers.
* Added `pane` option to all layers that can be changed (e.g. you can set `pane: 'overlayPane'` to a tile layer).
* Added `map` `createPane` method for custom panes. [#1742](https://github.com/Leaflet/Leaflet/issues/1742)
* Simplified map panes &mdash; removed `objectsPane`, all panes are on the same level now.
* Added `shadowPane` option to markers as well.
* Added `getEvents` method to all layers that returns an `{event: listener, ...}` hash; layers now manage its listeners automatically without having to do this in `onAdd`/`onRemove`.
* Added `togglePopup`, `setPopupContent`, `getPopup`, `isPopupOpen` methods to all layers. [#2279](https://github.com/Leaflet/Leaflet/issues/2279) [#2292](https://github.com/Leaflet/Leaflet/issues/2292)
* Improved performance of adding/removing layers with layers control present (instead of listening to any layer add/remove, the control only listens to layers added in configuration).
* Fixed `FeatureGroup` `getBounds` to work correctly when containing circle markers.
* Removed `Map` `tilelayersload` event.
* Removed `Popup` `open` and `close` events in favor of `add` and `remove` for consistency.
* Moved all layer-related logic in `Map.js` to `Layer.js`.
* Improved `FeatureGroup` `bindPopup` to accept a function for generating popup content, significantly improving memory footprint when adding popups to a huge number of layers (by [@patrickarlt](https://github.com/patrickarlt)). [#3109](https://github.com/Leaflet/Leaflet/pull/3109) [#3059](https://github.com/Leaflet/Leaflet/pull/3059)
* Added `ImageOverlay` interactivity (mouse events, etc.) (by [@snkashis](https://github.com/snkashis)). [#3009](https://github.com/Leaflet/Leaflet/pull/3009) [#1727](https://github.com/Leaflet/Leaflet/issues/1727)
* Added `ImageOverlay` `getBounds` (by [@brunob](https://github.com/brunob)). [#2848](https://github.com/Leaflet/Leaflet/pull/2848)
* Renamed `clickable` option to `interactive` (by [@AndriiHeonia](https://github.com/AndriiHeonia)). [#2838](https://github.com/Leaflet/Leaflet/pull/2838) [#2499](https://github.com/Leaflet/Leaflet/issues/2499)
* Changed the default z-index of panes to be bigger, leaving more room for customization (by [@patrickarlt](https://github.com/patrickarlt)). [#3591](https://github.com/Leaflet/Leaflet/pull/3591)
* Improved DOM event bubbling mechanism for layers (by [@yohanboniface](https://github.com/yohanboniface)). [Leaflet/Leaflet#3307](https://github.com/Leaflet/Leaflet/pull/3307) [#3450](https://github.com/Leaflet/Leaflet/pull/3450) [#3307](https://github.com/Leaflet/Leaflet/pull/3307)
* Added `nonBubblingEvents` option to layers (by [@yohanboniface](https://github.com/yohanboniface)). [#3605](https://github.com/Leaflet/Leaflet/pull/3605) [#3307](https://github.com/Leaflet/Leaflet/pull/3307) [#3604](https://github.com/Leaflet/Leaflet/issues/3604)

In addition, layer events implementation was rewritten to use **event delegation**, significantly improving add/remove performance and memory footprint. [#3032](https://github.com/Leaflet/Leaflet/pull/3032) [#46](https://github.com/Leaflet/Leaflet/issues/46)

### TileLayer & Projections API improvements

TileLayer code and everything projections-related has undergone a major refactoring, documented in PR [#2247](https://github.com/Leaflet/Leaflet/pull/2247). It includes the following changes (in addition to much cleaner and simpler code):

#### TileLayer API improvements

These changes make implementing custom grid-like layers for Leaflet much easier.

* Moved most of the `TileLayer` logic into the new `GridLayer` class (which `TileLayer` now inherits, extending it with logic specific to tile servers).
* Removed `TileLayer.Canvas` in favor of the much more flexible and powerful `GridLayer`.
* Improved tile wrapping and bounding logic in `TileLayer` to work transparently and completely depent on the CRS used; removed the need for `TileLayer` hacks when using custom projections.
* Added non-square tiles support (by [@IvanSanchez](https://github.com/IvanSanchez)). [#3573](https://github.com/Leaflet/Leaflet/pull/3573) [#3570](https://github.com/Leaflet/Leaflet/issues/3570)
* Removed `url` property in `tileload` and `tileloadstart` events (get it through `tile.src`).

#### Projections API improvements

These changes were targeted at removing any hardcoded projection-specific logic accross Leaflet classes, making it transparent and driven by the chosen CRS. They make using Leaflet with custom projections (including flat maps) much easier, and remove the need for ugly hacks in the [Proj4Leaflet](https://github.com/kartena/Proj4Leaflet) plugin.

* Added `CRS.Earth` which serves as a base for all Earth-based CRS (`EPSG3857` etc.). [#2345](https://github.com/Leaflet/Leaflet/pull/2345)
* Added `Projection` `bounds` property that defines bounds for different projections (`Mercator`, etc.) in projected coordinates (by [@perliedman](https://github.com/perliedman)).
* Added `CRS` `wrapLat` and `wrapLng` properties which define whether the world wraps on a given axis and in what range. Set as `[-180, 180]` for `EPSG:3857`, `EPSG:4326`, `EPSG:3395` by default.
* Added `CRS` and `Map` `wrapLatLng` (the latter depends on the chosen CRS).
* Added `CRS` `infinite` property that disables boundaries (the world can go on infinitely in any direction), default for `CRS.Simple`.
* Added `CRS` `getProjectedBounds` and `Map` `getPixelWorldBounds` methods that returns world bounds in projected coordinates depending on zoom (derived from `Projection` `bounds`) (by [@perliedman](https://github.com/perliedman)).
* Added `CRS` `unproject` method that converts coordinates in CRS-dependent units into `LatLng` coordinates (by [@sowelie](https://github.com/sowelie)).
* Added `Map` `distance(latlng1, latlng2)` method that takes CRS into account and works with flat projections.  [#2345](https://github.com/Leaflet/Leaflet/pull/2345) [#1442](https://github.com/Leaflet/Leaflet/issues/1442)
* Improved `Circle` to be approximated with an ellipse in Earth-based projections. [#2345](https://github.com/Leaflet/Leaflet/pull/2345)
* Fixed `EPSG:4326` to have correct tile pyramid (2x1 tiles at root).
* Fixed `Projection.SphericalMercator` to project to meter units (by [@calvinmetcalf](https://github.com/calvinmetcalf)).
* Fixed `Map` `worldCopyJump` option to work for other projections.
* Fixed `Circle` to work with flat projections. [#2345](https://github.com/Leaflet/Leaflet/pull/2345) [#1465](https://github.com/Leaflet/Leaflet/issues/1465)
* Fixed scale control precision in non-EPSG:3857 projections. [#2345](https://github.com/Leaflet/Leaflet/pull/2345)
* Fixed `ImageOverlay` not working properly in some non-standard projections. [#3011](https://github.com/Leaflet/Leaflet/issues/3011)


### Animations improvements and fractional zoom

Animation code in Leaflet had undergone a major rewrite (main PR: [#2382](https://github.com/Leaflet/Leaflet/pull/2382)), bringing improvements such as:

- Multi-level tile buffering for more seamless zooming experience with less flickering
- Optimal path animation (`map.flyTo`) for zooming to a particular place in a curve (simultaneously zooming and panning)
- Fractional zoom support &mdash; now you can do things like `map.setZoom(12.45)` and it just works.
- Layers now rely on `zoom` event in addition to `viewreset` for frame-by-frame zoom animations. [#3278](https://github.com/Leaflet/Leaflet/pull/3278)

### UX improvements

* Improved Leaflet events and DOM events memory footprint.
* Improved `Evented` `off` performance by about 2 times.

### Other breaking API changes

 * Added `GeoJSON` `resetStyle(layer)`, useful for resetting hover state.
 * Added `feature` property to layers created with `GeoJSON` (containing the GeoJSON feature data).
 * Added `FeatureGroup` `bringToFront` and `bringToBack` methods (so that they would work for multipolys).
 * Added optional `animate` argument to `Map` `invalidateSize` (by [@ajbeaven](https://github.com/ajbeaven)). [#857](https://github.com/Leaflet/Leaflet/pull/857)

### Bugfixes

 * Fixed a bug where map would occasionally flicker near the border on zoom or pan on Chrome.
 * Fixed a bug where `Path` `bringToFront` and `bringToBack` didn't return `this`.
 * Removed zoom out on Win/Meta key binding (since it interferes with global keyboard shortcuts). [#869](https://github.com/Leaflet/Leaflet/issues/869)

## 0.4.2 (August 1, 2012)

## 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`.

#### Other API improvements

 * Improved `on` and `off` methods to also accept `(eventHash[, context])`, as well as multiple space-separated events (by [@Guiswa](https://github.com/Guiswa)). [#770](https://github.com/Leaflet/Leaflet/pull/770)
 * Improved `off` to remove all listeners of the event if no function was specified (by [@Guiswa](https://github.com/Guiswa)). [#770](https://github.com/Leaflet/Leaflet/pull/770) [#691](https://github.com/Leaflet/Leaflet/issues/691)
 * Added `TileLayer` `setZIndex` method for controlling the order of tile layers (thanks to [@mattcurrie](https://github.com/mattcurrie)). [#837](https://github.com/Leaflet/Leaflet/pull/837)

 * Added `dashArray` option to vector layers for making dashed strokes (by [jacobtoye](https://github.com/jacobtoye)). [#821](https://github.com/Leaflet/Leaflet/pull/821) [#165](https://github.com/Leaflet/Leaflet/issues/165)
 * Added `Circle` `getBounds` method. [#440](https://github.com/Leaflet/Leaflet/issues/440)
 * Added `Circle` `getLatLng` and `getRadius` methods (by [@Guiswa](https://github.com/Guiswa)). [#655](https://github.com/Leaflet/Leaflet/pull/655)
 * Added `openPopup` method to all vector layers. [#246](https://github.com/Leaflet/Leaflet/issues/246)
 * Added public `redraw` method to vector layers (useful if you manipulate their `LatLng` points directly).
 * Added `Marker` `opacity` option and `setOpacity` method.
 * Added `Marker` `update` method. [#392](https://github.com/Leaflet/Leaflet/issues/392)

 * Fixed a regression where default marker icons wouldn't work if Leaflet include url contained a query string.
 * Fixed a regression where tiles sometimes flickered with black on panning in iOS.

## 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.
 * Added **layers control** (`Control.Layers`) for convenient layer switching.
 * Added ability to set **max bounds** within which users can pan/zoom. [#93](https://github.com/Leaflet/Leaflet/issues/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](https://github.com/Leaflet/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/Leaflet/Leaflet/issues/149)

 * Improved circles performance by not drawing them if they're off the clip region.
 * Improved stability of zoom animation (less flickering of tiles).

#### API improvements

## 0.2.1 (2011-06-18)

 * 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/Leaflet/Leaflet/issues/130)
 * Improved click responsiveness in mobile WebKit (now it happens without delay). [#26](https://github.com/Leaflet/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/Leaflet/Leaflet/issues/61)

#### API improvements

 * Added **MultiPolyline** and **MultiPolygon** layers. [#77](https://github.com/Leaflet/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` & `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 `opacity` option and `setOpacity` method to `TileLayer`.
 * Added `setLatLng` and `setIcon` methods to `Marker`.
 * Added `title` option to `Marker`.
 * Added `maxZoom` argument to `map.locateAndSetView` method.
 * Added ability to pass Geolocation options to map `locate` and `locateAndSetView` methods (by [@JasonSanford](https://github.com/JasonSanford)).
 * Improved `Popup` to accept HTML elements in addition to strings as its content.

#### Development workflow improvements

 * Added `Makefile` for building `leaflet.js` on non-Windows machines (by [@tmcw](https://github.com/tmcw)).
 * Improved `debug/leaflet-include.js` script to allow using it outside of `debug` folder (by [@antonj](https://github.com/antonj)).
