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.

• 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 #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). #2618 #3386 Leaflet/Leaflet#3279 #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). #3266 #2786
• Added vector layers fillRule option (by @bullgare). #2834
• Removed L_PREFER_CANVAS global switch and added Map preferCanvas option instead (by @yohanboniface). #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):

• 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
• Simplified map panes — 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 #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). #3109 #3059
• Added ImageOverlay interactivity (mouse events, etc.) (by @snkashis). #3009 #1727
• Added ImageOverlay getBounds (by @brunob). #2848
• Renamed clickable option to interactive (by @AndriiHeonia). #2838 #2499
• Changed the default z-index of panes to be bigger, leaving more room for customization (by @patrickarlt). #3591
• Improved DOM event bubbling mechanism for layers (by @yohanboniface). Leaflet/Leaflet#3307 #3450 #3307
• Added nonBubblingEvents option to layers (by @yohanboniface). #3605 #3307 #3604

In addition, layer events implementation was rewritten to use event delegation, significantly improving add/remove performance and memory footprint. #3032 #46

TileLayer & Projections API improvements

TileLayer code and everything projections-related has undergone a major refactoring, documented in PR #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). #3573 #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 plugin.

• Added CRS.Earth which serves as a base for all Earth-based CRS (EPSG3857 etc.). #2345
• Added Projection bounds property that defines bounds for different projections (Mercator, etc.) in projected coordinates (by @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).
• Added CRS unproject method that converts coordinates in CRS-dependent units into LatLng coordinates (by @sowelie).
• Added Map distance(latlng1, latlng2) method that takes CRS into account and works with flat projections. #2345 #1442
• Improved Circle to be approximated with an ellipse in Earth-based projections. #2345
• Fixed EPSG:4326 to have correct tile pyramid (2x1 tiles at root).
• Fixed Projection.SphericalMercator to project to meter units (by @calvinmetcalf).
• Fixed Map worldCopyJump option to work for other projections.
• Fixed Circle to work with flat projections. #2345 #1465
• Fixed scale control precision in non-EPSG:3857 projections. #2345
• Fixed ImageOverlay not working properly in some non-standard projections. #3011

Animations improvements and fractional zoom

Animation code in Leaflet had undergone a major rewrite (main PR: #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 — 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

UX improvements

• Improved panning inertia behavior so that there are no tearing during animation when panning around quickly. #2360
• Improved inertial scrolling to have a nicer, more natural feel (by @RickMohr). Leaflet/Leaflet#3063 #3063 #3062 #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). #951 #3000
• Improved keyboard zoom to zoom by 3 levels if shift key is pressed (by @yohanboniface). #3024
• Improved layers control to become scrollable when there are too many layers (by @rowanwins). #3571 #3167

Misc. performance improvements

• Significantly improved 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
• 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.
• Removed DomUtil getTranslateString and getScaleString methods.
• Removed DomUtil documentIsLtr method.
• Removed LatLng RAD_TO_DEG, DEG_TO_RAD and MAX_MARGIN constants.
• Renamed Util.limitExecByInterval to Util.throttle.

Other API improvements

• Added Evented class that now many Leaflet classes inherit from (instead of mixing in events methods in each class), while keeping the old includes: L.Mixin.Events syntax available. #2310
• Improved Class options to be prototypically inherited instead of copied over in children classes, which leads to more efficient memory use, faster object construction times and ability to change parent options that get propagated to all children automatically (by @jfirebaugh). #2300 #2294

0.4 (July 30, 2012)

API simplification

Leaflet 0.4 contains several API improvements that allow simpler, jQuery-like syntax (example) 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). #663 #646
• Added smooth zoom animation of markers, vector layers, image overlays and popups (by @danzel). #740 #758

• Added polyline and polygon editing. #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). #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). #7 #729
• Drag-panning now works even when there are markers in the starting point (helps on maps with lots of markers). #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). #586

GeoJSON API changes

GeoJSON API was improved to be simpler and more flexible (example). 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).

• 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). #770
• Improved off to remove all listeners of the event if no function was specified (by @Guiswa). #770 #691
• Added TileLayer setZIndex method for controlling the order of tile layers (thanks to @mattcurrie). #837
• Added Control.Layers autoZIndex option (on by default) to preserve the order of tile layers when switching.
• Added TileLayer redraw method for re-requesting tiles (by @greeninfo). #719
• Added TileLayer setUrl method for dynamically changing the tile URL template.
• Added bringToFront and bringToBack methods to TileLayer, ImageOverlay and vector layers. #185 #505

• Added dashArray option to vector layers for making dashed strokes (by jacobtoye). #821 #165
• Added Circle getBounds method. #440
• Added Circle getLatLng and getRadius methods (by @Guiswa). #655

• 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
• Improved Marker openPopup not to raise an error if it doesn't have a popup. #507
• Added ImageOverlay opacity option and setOpacity method. #438

• 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 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.
• Improved stability of zoom animation (less flickering of tiles).

• 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 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 L.Util.template method for simple string template evaluation.
• Added DomUtil.removeClass method (by @anru).
• 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
• Added Map boxzoomstart and boxzoomend events (by @zedd45). #554
• Added Popup contentupdate event (by @mehmeta). #548

Breaking API changes
