+About the GraphQL API
+
Decidim comes with an API that follows the GraphQL specification. It has a comprehensive coverage of all the public content that can be found on the website.
+
Currently, it is read-only (except for posting comments) but intends to cover anything that is published on the regular website.
+
Typically (although some particular installations may change that) you will find 3 relevant folders:
+
+
+URL/api The route where to make requests. Request are usually in the POST format.
+
+URL/api/docs This documentation, every Decidim site should provide one.
+
+URL/api/graphiqlGraphiQL is a in-browser IDE for exploring GraphQL APIs. Some Decidim installations may choose to remove access to this tool. In that case you can use a standalone version and use any URL/api as the endpoint
+
+
+Using the GraphQL APi
+
The GraphQL format is a JSON formatted text that is specified in a query. Response is a JSON object as well. For details about specification check the official GraphQL site.
+
For instance, you can check the version of a Decidim installation by using curl in the terminal:
The most practical way to experiment with GraphQL, however, is just to use the in-browser IDE GraphiQL. It provides access to the documentation and auto-complete (use CTRL-Space) for writing queries.
+
From now on, we will skip the "query" keyword for the purpose of readability. You can skip it too if you are using GraphiQL, if you are querying directly (by using CURL for instance) you will need to include it.
+
+Usage limits
+
Decidim is just a Rails application, meaning that any particular installation may implement custom limits in order to access the API (and the application in general).
+
By default (particular installations may change that), API uses the same limitations as the whole Decidim website, provided by the Gem Rack::Attack. These are 100 maximum requests per minute per IP to prevent DoS attacks
+
+Decidim structure, Types, collections and Polymorphism
+
There are no endpoints in the GraphQL specification, instead objects are organized according to their "Type".
+
These objects can be grouped in a single, complex query. Also, objects may accept parameters, which are "Types" as well.
+
Each "Type" is just a pre-defined structure with fields, or just an Scalar (Strings, Integers, Booleans, ...).
+
For instance, to obtain all the participatory processes in a Decidim installation published since January 2018 and order them by published date, we could execute the next query:
In the former query, each keyword represents a type, the words publishedSince, publishedAt, slug, locale are scalars, all of them Strings.
+
The other keywords however, are objects representing certain entities:
+
+
+participatoryProcesses is a type that represents a collection of participatory spaces. It accepts arguments (filter and order), which are other object types as well. slug and title are the fields of the participatory process we are interested in, there are "Types" too.
+
+filter is a ParticipatoryProcessFilter* input type, it has several properties that allows us to refine our search. One of them is the publishedSince property with the initial date from which to list entries.
+
+order is a ParticipatoryProcessSort type, works the same way as the filter but with the goal of ordering the results.
+
+title is a TranslatedField type, which allows us to deal with multi-language fields.
+
+
Finally, note that the returned object is an array, each item of which is a representation of the object we requested.
+
+
*About how filters and sorting are organized
+
There are two types of objects to filter and ordering collections in Decidim, they all work in a similar fashion. The type involved in filtering always have the suffix "Filter", for ordering it has the suffix "Sort".
Other collections (or connections) may have their own filters (i.e. ComponentFilter).
+
Each filter has its own properties, you should check any object in particular for details. The way they work with multi-languages fields, however, is the same:
+
Let's say we have some searchable object with a multi-language field called title, and we have a filter that allows us to search through this field. How should it work? Should we look up content for every language in the field? or should we stick to a specific language?
+
In our case, we've decided to search only one particular language of a multi-language field but we let you choose which language to search.
+If no language is specified, the configured as default in the organization will be used. The keyword to specify the language is locale, and it should be provided in the 2 letters ISO 639-1 format (en = English, es = Spanish, ...).
Of course, you can combine both filter and order. Also remember to check availability of this type of behaviour for any particular filter/sort.
+
+
+Decidim main types
+
Decidim has 2 main types of objects through which content is provided. These are Participatory Spaces and Components.
+
A participatory space is the first level, currently there are 5 officially supported: Participatory Processes, Assemblies, Consultations, Conferences and Initiatives. For each participatory process there will correspond a collection type and a "single item" type.
+
The previous example uses the collection type for participatory processes. You can try assemblies, conferences, consultations or initiatives for the others. Note that each collection can implement their own filter and order types with different properties.
+
As an example for a single item query, you can run:
First, note that we are querying, in singular, the type participatoryProcess, with a different parameter, slug*, (a String). We can use the id instead if we know it.
+
Second, the response is not an Array, it is just the object we requested. We can expect to return null if the object is not found.
+
+
* The slug is a convenient way to find a participatory space as is (usually) in the URL.
+
For instance, consider this real case from Barcelona:
Every participatory space may (and should) have some components. There are 9 official components, these are Proposals, Page, Meetings, Budgets, Surveys, Accountability, Debates, Sortitions and Blog. Plugins may add their own components.
+
If you know the id* of a specific component you can obtain it by querying it directly:
+
{
+ component(id:2) {
+ id
+ name {
+ translation(locale:"en")
+ }
+ __typename
+ participatorySpace {
+ id
+ type
+ }
+ }
+}
+
We can also apply some filters by using the ComponentFilter type. In the next query we would like to find all the components with geolocation enabled in the assembly with id=2:
Note that, in this case, there is only one component returned, "Meetings". In some cases Proposals can be geolocated too therefore would be returned in this query.
+
+Polymorphism and connections
+
Many relationships between tables in Decidim are polymorphic, this means that the related object can belong to different classes and share just a few properties in common.
+
For instance, components in a participatory space are polymorphic, while the concept of component is generic and all of them share properties like published date, name or weight, they differ in the rest. Proposals have the status field while Meetings have an agenda.
+
Another example are the case of linked resources, these are properties that may link objects of different nature between components or participatory spaces.
+
In a very simplified way (to know more please refer to the official guide), GraphQL polymorphism is handled through the operator ... on. You'll know when a field is polymorphic because the property __typename, which tells you the type of that particular object, will change accordingly.
+
In the previous examples we've queried for this property:
Until the ... on Proposals line, there's nothing new. We are requesting the Assembly participatory space identified by the id=3, then listing all its components with the type "Proposals". All the components share the id and name properties, so we can just add them at the query.
+
After that, we want content specific from the Proposals type. In order to do that we must tell the server that the content we will request shall only be executed if the types matches Proposals. We do that by wrapping the rest of the query in the ... on Proposals clause.
+
The next line is just a property of the type Proposals which is a type of collection called a "connection". A connection works similar as normal collection (such as components) but it can handle more complex cases.
+
Typically, a connection is used to paginate long results, for this purpose the results are not directly available but encapsulated inside the list edges in several node results. Also there are more arguments available in order to navigate between pages. This are the arguments:
+
+
+first: Returns the first n elements from the list
+
+after: Returns the elements in the list that come after the specified cursor
+
+
+last: Returns the last n elements from the list
+
+before: Returns the elements in the list that come before the specified cursor
+
As you can see, a part from the edges list, you can access to the object pageInfo which gives you the information needed to navigate through the different pages.
+
For more info on how connections work, you can check the official guide:

GraphQL Interfaces are a sort of "parent object" from which other objects can "inherit" from. For example, Stars is considered an interface, because both Repository and Gist can be starred. An interface has its own list of named fields that are shared by implementing objects.

+__Type
+
The fundamental unit of any GraphQL Schema is the type. There are many kinds of types in GraphQL as represented by the __TypeKind enum.
+
Depending on the kind of a type, certain fields describe information about that type. Scalar types provide no information beyond a name and description, while Enum types provide their values. Object and Interface types provide the fields they describe. Abstract types, Union and Interface, provide the Object types possible at runtime. List and NonNull types compose other types.

-## 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 — 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 — 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.

-* Renamed `Util.limitExecByInterval` to `Util.throttle`.
-
-### Other API improvements
-

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

-
-## 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)
- * 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)

-
-## 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).

-Leaflet is the leading open-source JavaScript library for **mobile-friendly interactive maps**.
-Weighing just about 37 KB of gzipped JS 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][].
-For **Leaflet downloads** (including the built master 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!
