## 1.0-beta1 (2015-07-14)
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 panning inertia behavior so that there are no tearing during animation when panning around quickly. [#2360](https://github.com/Leaflet/Leaflet/issues/2360)
* Improved inertial scrolling to have a nicer, more natural feel (by [@RickMohr](https://github.com/RickMohr)). [Leaflet/Leaflet#3063](https://github.com/Leaflet/Leaflet/pull/3063) [#3063](https://github.com/Leaflet/Leaflet/pull/3063) [#3062](https://github.com/Leaflet/Leaflet/issues/3062) [#2987](https://github.com/Leaflet/Leaflet/issues/2987)
* Added popup fade out animation.
* Improved keyboard support to ignore keystrokes with modifier keys (Ctrl, Alt, Meta) to not interfere with OS shortcuts.
* Made popup to close when pressing Escape (by [@snkashis](https://github.com/snkashis)). [#951](https://github.com/Leaflet/Leaflet/issues/951) [#3000](https://github.com/Leaflet/Leaflet/pull/3000)
* Improved keyboard zoom to zoom by 3 levels if shift key is pressed (by [@yohanboniface](https://github.com/yohanboniface)). [#3024](https://github.com/Leaflet/Leaflet/pull/3024)
* Improved layers control to become scrollable when there are too many layers (by [@rowanwins](https://github.com/rowanwins)). [#3571](https://github.com/Leaflet/Leaflet/pull/3571) [#3167](https://github.com/Leaflet/Leaflet/issues/3167)
### Misc. performance improvements
* Significantly [improved](http://jsperf.com/leaflet-parsefloat-in-latlng/2) `LatLng` creation performance (8x).
* Improved performance of layer objects construction.
* Significantly improved `FeatureGroup` (and correspondingly `GeoJSON`) layer adding and events performance (about 10x) by implementing a much better event propagation mechanism. [#2311](https://github.com/Leaflet/Leaflet/pull/2311)
* Improved Leaflet events and DOM events memory footprint.
* Improved `Evented` `off` performance by about 2 times.
### Other breaking API changes
* Changed `DomUtil` `off` to require `context` attribute if you remove a listener that was previously added with a particular context.
* Removed `DomUtil.getViewportOffset` method as it is no longer necessary.

## 0.6 (2013-06-26)
### 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).
* `Map` `invalidateSize` no longer fires `move` and `moveend` events if the map size didn't change. [#1819](https://github.com/Leaflet/Leaflet/issues/1819)

## 0.5 (2013-01-17)
### 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 (2012-08-07)
### 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).
* 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)

## 0.4 (2012-07-30)
### 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)

* Fixed a regression where tiles sometimes flickered with black on panning in iOS.
## 0.3 (2012-02-13)
### 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)
* 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.
* Improved stability of zoom animation (less flickering of tiles).
#### 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](https://github.com/Fabiz)). [#377](https://github.com/Leaflet/Leaflet/pull/377)

* Fixed a bug that caused an error when clicking vector layers under iOS. [#204](https://github.com/Leaflet/Leaflet/issues/204)
* Fixed crash on Android 3+ when panning or zooming (by [@florian](https://github.com/florianf)). [#137](https://github.com/Leaflet/Leaflet/issues/137)
* Fixed a bug on Android 2/3 that sometimes caused the map to disappear after zooming. [#69](https://github.com/Leaflet/Leaflet/issues/69)
* Fixed a bug on Android 3 that caused tiles to shift position on a big map.
* Fixed a bug that caused the map to pan when touch-panning inside a popup. [#452](https://github.com/Leaflet/Leaflet/issues/452)
* Fixed a bug that caused click delays on zoom control.
## 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 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 `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)).
* Improved `L` definition to be compatible with CommonJS. [#122](https://github.com/Leaflet/Leaflet/issues/122)
### Bug fixes
#### General bugfixes
* Fixed a bug where zooming is broken if the map contains a polygon and you zoom to an area where it's not visible. [#47](https://github.com/Leaflet/Leaflet/issues/47)
* Fixed a bug where closed polylines would not appear on the map.
* Fixed a bug where marker that was added, removed and then added again would not appear on the map. [#66](https://github.com/Leaflet/Leaflet/issues/66)
* Fixed a bug where tile layer that was added, removed and then added again would not appear on the map.
* Fixed a bug where some tiles would not load when panning across the date line. [#97](https://github.com/Leaflet/Leaflet/issues/97)
* Fixed a bug where map div with `position: absolute` is reset to `relative`. [#100](https://github.com/Leaflet/Leaflet/issues/100)
* Fixed a bug that caused an error when trying to add a marker without shadow in its icon.
* Fixed a bug where popup content would not update on `setContent` call. [#94](https://github.com/Leaflet/Leaflet/issues/94)
* Fixed a bug where double click zoom wouldn't work if popup is opened on map click
* Fixed a bug with click propagation on popup close button. [#99](https://github.com/Leaflet/Leaflet/issues/99)
* Fixed inability to remove ImageOverlay layer.
#### Browser bugfixes
* Fixed a bug where paths would not appear in IE8.
* Fixed a bug where there were occasional slowdowns before zoom animation in WebKit. [#123](https://github.com/Leaflet/Leaflet/issues/123)
* Fixed incorrect zoom animation & popup styling in Opera 11.11.
* Fixed popup fade animation in Firefox and Opera.
* Fixed a bug where map isn't displayed in Firefox when there's an `img { max-width: 100% }` rule.
#### Mobile browsers bugfixes
* Fixed a bug that prevented panning on some Android 2.1 (and possibly older) devices. [#84](https://github.com/Leaflet/Leaflet/issues/84)
* Disabled zoom animation on Android by default because it's buggy on some devices (will be enabled back when it's stable enough). [#32](https://github.com/Leaflet/Leaflet/issues/32)
* Fixed a bug where map would occasionally break while multi-touch-zooming on iOS. [#32](https://github.com/Leaflet/Leaflet/issues/32)
* Fixed a bug that prevented panning/clicking on Android 3 tablets. [#121](https://github.com/Leaflet/Leaflet/issues/121)
* Fixed a bug that prevented panning/clicking on Opera Mobile. [#138](https://github.com/Leaflet/Leaflet/issues/138)
* Fixed potentional memory leak on WebKit when removing tiles, thanks to [@Scalar4eg](https://github.com/Scalar4eg). [#107](https://github.com/Leaflet/Leaflet/issues/107)
## 0.1 (2011-05-13)

Leaflet was created 11 years ago by [Volodymyr Agafonkin](https://agafonkin.com), a Ukrainian citizen living in Kyiv.
Russian bombs are now falling over Volodymyr's hometown. His family, his friends, his neighbours, thousands and thousands of absolutely wonderful people, are either seeking refuge or fighting for their lives.
The Russian soldiers have already killed tens of thousands of civilians, including women and children, and are committing mass war crimes like gang rapes, executions, looting, and targeted bombings of civilian shelters and places of cultural significance. The death toll keeps rising, and Ukraine needs your help.
As Volodymyr [expressed a few days before the invasion](https://twitter.com/LeafletJS/status/1496051256409919489):
> If you want to help, educate yourself and others on the Russian threat, follow reputable journalists, demand severe Russian sanctions and Ukrainian support from your leaders, protest war, reach out to Ukrainian friends, donate to Ukrainian charities. Just don't be silent.
Ukrainians are recommending the [Come Back Alive](https://savelife.in.ua/en/) charity. For other options, see [StandWithUkraine](https://stand-with-ukraine.pp.ua).
If an appeal to humanity doesn't work for you, I'll appeal to your egoism: the future of Ukrainian citizens is the future of Leaflet.
It is chilling to see Leaflet being used for [documenting Russia's war crimes](https://ukraine.bellingcat.com/), [factual reporting of the war](https://liveuamap.com/) and for coordination of humanitarian efforts [in Romania](https://refugees.ro/) and [in Poland](https://dopomoha.pl/). We commend these uses of Leaflet.
If you support the actions of the Russian government (even after reading all this), do everyone else a favour and [carry some seeds in your pocket](https://www.theguardian.com/world/video/2022/feb/25/ukrainian-woman-sunflower-seeds-russian-soldiers-video).
Yours truly,<br>
Leaflet maintainers.

Leaflet is the leading open-source JavaScript library for **mobile-friendly interactive maps**.
Weighing just about 39 KB of gzipped JS plus 4 KB of gzipped CSS code, it has all the mapping [features][] most developers ever need.
Leaflet is designed with *simplicity*, *performance* and *usability* in mind.
It works efficiently across all major desktop and mobile platforms out of the box,
taking advantage of HTML5 and CSS3 on modern browsers while being accessible on older ones too.
It can be extended with a huge amount of [plugins][],
has a beautiful, easy to use and [well-documented][] API
and a simple, readable [source code][] that is a joy to [contribute][] to.
For more info, docs and tutorials, check out the [official website][].<br>
For **Leaflet downloads** (including the built main version), check out the [download page][].
We're happy to meet new contributors.
If you want to **get involved** with Leaflet development, check out the [contribution guide][contribute].
Let's make the best mapping library that will ever exist,
and push the limits of what's possible with online maps!

* @class Control.Layers
* @aka L.Control.Layers
* @inherits Control
*
* The layers control gives users the ability to switch between different base layers and switch overlays on/off (check out the [detailed example](https://leafletjs.com/examples/layers-control/)). Extends `Control`.
*
* @example
*
* ```js
* var baseLayers = {
* "Mapbox": mapbox,
* "OpenStreetMap": osm
* };
*
* var overlays = {
* "Marker": marker,
* "Roads": roadsLayer
* };
*
* L.control.layers(baseLayers, overlays).addTo(map);
* ```
*
* The `baseLayers` and `overlays` parameters are object literals with layer names as keys and `Layer` objects as values:
*
* ```js
* {
* "<someName1>": layer1,
* "<someName2>": layer2
* }
* ```
*
* The layer names can contain HTML, which allows you to add additional styling to the items:
*
* ```js
* {"<img src='my-layer-icon' /> <span class='my-layer-item'>My Layer</span>": myLayer}
* ```

@class Class
@aka L.Class
L.Class powers the OOP facilities of Leaflet and is used to create almost all of the Leaflet classes documented here.
In addition to implementing a simple classical inheritance model, it introduces several special properties for convenient code organization — options, includes and statics.
@example
```js
var MyClass = L.Class.extend({
initialize: function (greeter) {
this.greeter = greeter;
// class constructor
},
greet: function (name) {
alert(this.greeter + ', ' + name)
}
});
// create instance of MyClass, passing "Hello" to the constructor
var a = new MyClass("Hello");
// call greet method, alerting "Hello, World"
a.greet("World");
```
@section Class Factories
@example
You may have noticed that Leaflet objects are created without using
the `new` keyword. This is achieved by complementing each class with a
lowercase factory method:
```js
new L.Map('map'); // becomes:
L.map('map');
```
The factories are implemented very easily, and you can do this for your own classes:
```js
L.map = function (id, options) {
return new L.Map(id, options);
};
```
@section Inheritance
@example
You use L.Class.extend to define new classes, but you can use the same method on any class to inherit from it:
```js
var MyChildClass = MyClass.extend({
// ... new properties and methods
});
```
This will create a class that inherits all methods and properties of the parent class (through a proper prototype chain), adding or overriding the ones you pass to extend. It will also properly react to instanceof:
```js
var a = new MyChildClass();
a instanceof MyChildClass; // true
a instanceof MyClass; // true
```
You can call parent methods (including constructor) from corresponding child ones (as you do with super calls in other languages) by accessing parent class prototype and using JavaScript's call or apply:
```
var MyChildClass = MyClass.extend({
initialize: function () {
MyClass.prototype.initialize.call(this, "Yo");
},
greet: function (name) {
MyClass.prototype.greet.call(this, 'bro ' + name + '!');
}
});
var a = new MyChildClass();
a.greet('Jason'); // alerts "Yo, bro Jason!"
```
@section Options
@example
`options` is a special property that unlike other objects that you pass
to `extend` will be merged with the parent one instead of overriding it
completely, which makes managing configuration of objects and default
values convenient:
```js
var MyClass = L.Class.extend({
options: {
myOption1: 'foo',
myOption2: 'bar'
}
});
var MyChildClass = MyClass.extend({
options: {
myOption1: 'baz',
myOption3: 5
}
});
var a = new MyChildClass();
a.options.myOption1; // 'baz'
a.options.myOption2; // 'bar'
a.options.myOption3; // 5
```
There's also [`L.Util.setOptions`](#util-setoptions), a method for
conveniently merging options passed to constructor with the defaults
defines in the class:
```js
var MyClass = L.Class.extend({
options: {
foo: 'bar',
bla: 5
},
initialize: function (options) {
L.Util.setOptions(this, options);
...
}
});
var a = new MyClass({bla: 10});
a.options; // {foo: 'bar', bla: 10}
```
Note that the options object allows any keys, not just
the options defined by the class and its base classes.
This means you can use the options object to store
application specific information, as long as you avoid
keys that are already used by the class in question.
@section Includes
@example
`includes` is a special class property that merges all specified objects into the class (such objects are called mixins).
```js
var MyMixin = {
foo: function () { ... },
bar: 5
};
var MyClass = L.Class.extend({
includes: MyMixin
});
var a = new MyClass();
a.foo();
```
You can also do such includes in runtime with the `include` method:
```js
MyClass.include(MyMixin);
```
`statics` is just a convenience property that injects specified object properties as the static properties of the class, useful for defining constants:
```js
var MyClass = L.Class.extend({
statics: {
FOO: 'bar',
BLA: 5
}
});
MyClass.FOO; // 'bar'
```
@section Constructor hooks
@example
If you're a plugin developer, you often need to add additional initialization code to existing classes (e.g. editing hooks for `L.Polyline`). Leaflet comes with a way to do it easily using the `addInitHook` method:
```js
MyClass.addInitHook(function () {
// ... do something in constructor additionally
// e.g. add event listeners, set custom properties etc.
});
```
You can also use the following shortcut when you just need to make one additional method call:
```js
MyClass.addInitHook('methodName', arg1, arg2, …);
```

@namespace Event objects
Whenever a class inheriting from `Evented` fires an event, a listener function
will be called with an event argument, which is a plain object containing
information about the event. For example:
```js
map.on('click', function(ev) {
alert(ev.latlng); // ev is an event object (MouseEvent in this case)
});
```
The information available depends on the event type:

be the same as the `target`.
@property propagatedFrom: Object
For propagated events, the last object that propagated the event to its
event parent.
@property layer: Object
**Deprecated.** The same as `propagatedFrom`.

@class Interactive layer
@inherits Layer
Some `Layer`s can be made interactive - when the user interacts
with such a layer, mouse events like `click` and `mouseover` can be handled.
Use the [event handling methods](#evented-method) to handle these events.
@option interactive: Boolean = true
If `false`, the layer will not emit mouse events and will act as a part of the underlying map.
@option bubblingMouseEvents: Boolean = true
When `true`, a mouse event on this layer will trigger the same event on the map
(unless [`L.DomEvent.stopPropagation`](#domevent-stoppropagation) is used).
@section Mouse events
@event click: MouseEvent
Fired when the user clicks (or taps) the layer.
@event dblclick: MouseEvent
Fired when the user double-clicks (or double-taps) the layer.
@event mousedown: MouseEvent
Fired when the user pushes the mouse button on the layer.
@event mouseup: MouseEvent
Fired when the user releases the mouse button pushed on the layer.
@event mouseover: MouseEvent
Fired when the mouse enters the layer.
@event mouseout: MouseEvent
Fired when the mouse leaves the layer.
@event contextmenu: MouseEvent
Fired when the user right-clicks on the layer, prevents
default browser context menu from showing if there are listeners on
this event. Also fired on mobile when the user holds a single touch
for a second (also called long press).

* - the `offset` Tooltip option: it defaults to [0, 0], and it's specific to one tooltip.
* Add a positive x offset to move the tooltip to the right, and a positive y offset to
* move it to the bottom. Negatives will move to the left and top.

* @class GridLayer
* @inherits Layer
* @aka L.GridLayer
*
* Generic class for handling a tiled grid of HTML elements. This is the base class for all tile layers and replaces `TileLayer.Canvas`.
* GridLayer can be extended to create a tiled grid of HTML elements like `<canvas>`, `<img>` or `<div>`. GridLayer will handle creating and animating these DOM elements for you.
*
*
* @section Synchronous usage
* @example
*
* To create a custom layer, extend GridLayer and implement the `createTile()` method, which will be passed a `Point` object with the `x`, `y`, and `z` (zoom level) coordinates to draw your tile.
*
* ```js
* var CanvasLayer = L.GridLayer.extend({
* createTile: function(coords){
* // create a <canvas> element for drawing
* var tile = L.DomUtil.create('canvas', 'leaflet-tile');
*
* // setup tile width and height according to the options
* var size = this.getTileSize();
* tile.width = size.x;
* tile.height = size.y;
*
* // get a canvas context and draw something on it using coords.x, coords.y and coords.z
* var ctx = tile.getContext('2d');
*
* // return the tile so it can be rendered on screen
* return tile;
* }
* });
* ```
*
* @section Asynchronous usage
* @example
*
* Tile creation can also be asynchronous, this is useful when using a third-party drawing library. Once the tile is finished drawing it can be passed to the `done()` callback.
*
* ```js
* var CanvasLayer = L.GridLayer.extend({
* createTile: function(coords, done){
* var error;
*
* // create a <canvas> element for drawing
* var tile = L.DomUtil.create('canvas', 'leaflet-tile');
*
* // setup tile width and height according to the options
* var size = this.getTileSize();
* tile.width = size.x;
* tile.height = size.y;
*
* // draw something asynchronously and pass the tile to the done() callback
* setTimeout(function() {
* done(error, tile);
* }, 1000);
*
* return tile;
* }
* });
* ```
*

*
* ```js
* var latlngs = [

This file documents the common options passed to several map methods.
@miniclass Locate options (Map)
@aka locate options
@section
Some of the geolocation methods for `Map` take in an `options` parameter. This
is a plain javascript object with the following optional components:
@option watch: Boolean = false
If `true`, starts continuous watching of location changes (instead of detecting it
once) using W3C `watchPosition` method. You can later stop watching using
`map.stopLocate()` method.
@option setView: Boolean = false
If `true`, automatically sets the map view to the user location with respect to
detection accuracy, or to world view if geolocation failed.
@option maxZoom: Number = Infinity
The maximum zoom for automatic view setting when using `setView` option.
@option timeout: Number = 10000
Number of milliseconds to wait for a response from geolocation before firing a
`locationerror` event.
@option maximumAge: Number = 0
Maximum age of detected location. If less than this amount of milliseconds
passed since last geolocation response, `locate` will return a cached location.
@option enableHighAccuracy: Boolean = false
Enables high accuracy, see [description in the W3C spec](https://w3c.github.io/geolocation-api/#enablehighaccuracy-member).
@miniclass Zoom options (Map)
@aka zoom options
@section
Some of the `Map` methods which modify the zoom level take in an `options`
parameter. This is a plain javascript object with the following optional
components:
@option animate: Boolean
If not specified, zoom animation will happen if the zoom origin is inside the
current view. If `true`, the map will attempt animating zoom disregarding where
zoom origin is. Setting `false` will make it always reset the view completely
without animation.
@miniclass Pan options (Map)
@aka pan options
@section
Some of the `Map` methods which modify the center of the map take in an `options`
parameter. This is a plain javascript object with the following optional
components:
@option animate: Boolean
If `true`, panning will always be animated if possible. If `false`, it will
not animate panning, either resetting the map view if panning more than a
screen away, or just setting a new offset for the map pane (except for `panBy`
which always does the latter).
@option duration: Number = 0.25
Duration of animated panning, in seconds.
@option easeLinearity: Number = 0.25
The curvature factor of panning animation easing (third parameter of the
[Cubic Bezier curve](https://cubic-bezier.com/)). 1.0 means linear animation,
and the smaller this number, the more bowed the curve.
@option noMoveStart: Boolean = false
If `true`, panning won't fire `movestart` event on start (used internally for
panning inertia).
@miniclass Zoom/pan options (Map)
@aka zoom/pan options
@inherits Zoom options
@inherits Pan options
@miniclass Padding options (Map)
@aka padding options
@option paddingTopLeft: Point = [0, 0]
Sets the amount of padding in the top left corner of a map container that
shouldn't be accounted for when setting the view to fit bounds. Useful if you
have some control overlays on the map like a sidebar and you don't want them
to obscure objects you're zooming to.
@option paddingBottomRight: Point = [0, 0]
The same for the bottom right corner of the map.
@option padding: Point = [0, 0]
Equivalent of setting both top left and bottom right padding to the same value.
@miniclass FitBounds options (Map)
@aka fitBounds options
@inherits Zoom/pan options
@inherits Padding options
@option maxZoom: Number = null
The maximum possible zoom to use.
