+The `ol` package contains a `src/` folder with JSDoc annotated sources. TypeScript can get type definitions from these sources with a `jsconfig.json` config file in the project root:
+```js
+{
+  "compilerOptions": {
+    "checkJs": true,
+    // Point to the JSDoc typed sources when using modules from the ol package

+  },
+  "include": [

+    "node_modules/ol/**/*.js"
+  ]
+}
+```

 ## Supported Browsers
 
 OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io) for `requestAnimationFrame` and `Element.prototype.classList` are required, and using the KML format requires a polyfill for `URL`.

 ### Next version
 
+#### Backwards incompatible changes
+
+##### The `setCenter`, `setZoom`, `setResolution` and `setRotation` methods on `ol/View` do not bypass constraints anymore
+
+Previously, these methods allowed setting values that were inconsistent with the given view constraints.
+This is no longer the case and all changes to the view state now follow the same logic:
+target values are provided and constraints are applied on these to determine the actual values to be used.
+
+##### Removal of the `constrainResolution` option on `View.fit`, `PinchZoom`, `MouseWheelZoom` and `ol/interaction.js`
+
+The `constrainResolution` option is now only supported by the `View` class. A `View.setResolutionConstrained` method was added as well.
+
+Generally, the responsibility of applying center/rotation/resolutions constraints was moved from interactions and controls to the `View` class.
+
+##### The view `extent` option now applies to the whole viewport
+
+Previously, this options only constrained the view *center*. This behaviour can still be obtained by specifying `constrainCenterOnly` in the view options.
+
+As a side effect, the view `rotate` method is gone and has been replaced with `adjustRotation` which takes a delta as input.
+
+##### Removal of deprecated methods
+
+The `inherits` function that was used to inherit the prototype methods from one constructor into another has been removed.
+The standard ECMAScript classes should be used instead.
+
+The deprecated `getSnapToPixel` and `setSnapToPixel` functions from the `ImageStyle` class have been removed.
+
+##### New internal tile coordinates
+
+Previously, the internal tile coordinates used in the library had an unusual row order – the origin of the tile coordinate system was at the top left as expected, but the rows increased upwards.  This meant that all tile coordinates within a tile grid's extent had negative `y` values.
+
+Now, the internal tile coordinates used in the library have the same row order as standard (e.g. XYZ) tile coordinates.  The origin is at the top left (as before), and rows or `y` values increase downward.  So the top left tile of a tile grid is now `0, 0`, whereas it was `0, -1` before.
+
+```
+x, y values for tile coordinates
+
+origin
+  *__________________________
+  |        |        |        |
+  |  0, 0  |  1, 0  |  2, 0  |
+  |________|________|________|
+  |        |        |        |
+  |  0, 1  |  1, 1  |  2, 1  |
+  |________|________|________|
+  |        |        |        |
+  |  0, 2  |  1, 2  |  2, 2  |
+  |________|________|________|
+```
+
+This change should only affect you if you were using a custom `tileLoadFunction` or `tileUrlFunction`.  For example, if you used to have a `tileUrlFunction` that looked like this:
+
+```js
+// before
+function tileUrlFunction(tileCoord) {
+  const z = tileCoord[0];
+  const x = tileCoord[1];
+  const y = -tileCoord[2] - 1;
+  // do something with z, x, y
+}
+```
+
+You would now do something like this:
+```js
+// after
+function tileUrlFunction(tileCoord) {
+  const z = tileCoord[0];
+  const x = tileCoord[1];
+  const y = tileCoord[2];
+  // do something with z, x, y
+}
+```
+
+In addition (this should be exceedingly rare), if you previously created a `ol/tilegrid/WMTS` by hand and you were providing an array of `sizes`, you no longer have to provide a negative height if your tile origin is the top-left corner (the common case).  On the other hand, if you are providing a custom array of `sizes` and your origin is the bottom of the grid (this is uncommon), your height values must now be negative.
+
+##### Removal of the "vector" render mode for vector tile layers
+
+If you were previously using `VectorTile` layers with `renderMode: 'vector'`, you have to remove this configuration option. That mode was removed. `'hybrid'` (default) and `'image'` are still available.
+
+##### Removal of the "renderMode" option for vector layers
+
+If you were previously using `Vector` layers with `renderMode: 'image'`, you have to remove this configuration option. Instead, use the new `ol/layer/VectorImage` layer with your `ol/source/Vector`.
+
+##### New `prerender` and `postrender` layer events replace old `precompose`, `render` and `postcompose` events
+
+If you were previously registering for `precompose` and `postcompose` events, you should now register for `prerender` and `postrender` events on layers.  Instead of the previous `render` event, you should now listen for `postrender`. Layers are no longer composed to a single Canvas element.  Instead, they are added to the map viewport as individual elements.
+
+##### New `getVectorContext` function provides access to the immediate vector rendering API
+
+Previously, render events included a `vectorContext` property that allowed you to render features or geometries directly to the map.  This is still possible, but you now have to explicitly create a vector context with the `getVectorContext` function.  This change makes the immediate rendering API an explicit dependency if your application uses it.  If you don't use this API, your application bundle will not include the vector rendering modules (as it did before).
+
+Here is an abbreviated example of how to use the `getVectorContext` function:
+
+```js
+import {getVectorContext} from 'ol/render';
+
+// construct your map and layers as usual
+
+layer.on('postrender', function(event) {
+  const vectorContext = getVectorContext(event);
+  // use any of the drawing methods on the vector context
+});
+```
+
+##### Layers can only be added to a single map
+
+Previously, it was possible to render a single layer in two maps.  Now, each layer can only belong to a single map (in the same way that a single DOM element can only have one parent).
+
+##### The `OverviewMap` requires a list of layers.
+
+Due to the constraint above (layers can only be added to a single map), the overview map needs to be constructed with a list of layers.
+
+##### The `ol/Graticule` has been replaced by `ol/layer/Graticule`
+
+Previously, a graticule was not a layer.  Now it is.  See the graticule example for details on how to add a graticule layer to your map.
+
+##### `ol/format/Feature` API change
+
+The `getLastExtent()` method, which was required for custom `tileLoadFunction`s in `ol/source/Vector`, has been removed because it is no longer needed (see below).
+
+##### `ol/VectorTile` API changes
+
+* Removal of the `getProjection()` and `setProjection()` methods. These were used in custom `tileLoadFunction`s on `ol/source/VectorTile`, which work differently now (see below).
+* Removal of the `getExtent()` and `setExtent()` methods. These were used in custom `tileLoadFunction`s on `ol/source/VectorTile`, which work differently now (see below).
+
+##### Custom tileLoadFunction on a VectorTile source needs changes
+
+Previously, applications needed to call `setProjection()` and `setExtent()` on the tile in a custom `tileLoadFunction` on `ol/source/VectorTile`. The format's `getLastExtent()` method was used to get the extent. All this is no longer needed. Instead, the `extent` (first argument to the loader function) and `projection` (third argument to the loader function) are simply passed as `extent` and `featureProjection` options to the format's `readFeatures()` method.
+
+Example for an old `tileLoadFunction`:
+
+```js
+function(tile, url) {
+  tile.setLoader(function() {
+    fetch(url).then(function(response) {
+      response.arrayBuffer().then(function(data) {
+        var format = tile.getFormat();
+        tile.setProjection(format.readProjection(data));
+        tile.setFeatures(format.readFeatures(data, {
+          // featureProjection is not required for ol/format/MVT
+          featureProjection: map.getView().getProjection()
+        }));
+        tile.setExtent(format.getLastExtent());
+      })
+    })
+  }
+});
+```
+
+This function needs to be changed to:
+
+```js
+function(tile, url) {
+  tile.setLoader(function(extent, resolution, projection) {
+    fetch(url).then(function(response) {
+      response.arrayBuffer().then(function(data) {
+        var format = tile.getFormat();
+        tile.setFeatures(format.readFeatures(data, {
+          // extent is only required for ol/format/MVT
+          extent: extent,
+          featureProjection: projection
+        }));
+      })
+    })
+  }
+});
+```
+
+##### Drop of support for the experimental WebGL renderer
+
+The WebGL map and layers renderers are gone, replaced by a `WebGLHelper` function that provides a lightweight,
+low-level access to the WebGL API. This is implemented in a new `WebGLPointsLayer` which does simple rendering of large number
+of points with custom shaders.
+
+This is now used in the `Heatmap` layer.
+
+The removed classes and components are:
+* `WebGLMap` and `WebGLMapRenderer`
+* `WebGLLayerRenderer`
+* `WebGLImageLayer` and `WebGLImageLayerRenderer`
+* `WebGLTileLayer` and `WebGLTileLayerRenderer`
+* `WebGLVectorLayer` and `WebGLVectorLayerRenderer`
+* `WebGLReplay` and derived classes, along with associated shaders
+* `WebGLReplayGroup`
+* `WebGLImmediateRenderer`
+* `WebGLMap`
+* The shader build process using `mustache` and the `Makefile` at the root
+
+##### Removal of the AtlasManager
+
+Following the removal of the experimental WebGL renderer, the AtlasManager has been removed as well. The atlas was only used by this renderer.
+The non API `getChecksum` functions of the style is also removed.
+
+##### Change of the behavior of the vector source's clear() and refresh() methods
+
+The `ol/source/Vector#clear()` method no longer triggers a reload of the data from the server. If you were previously using `clear()` to refetch from the server, you now have to use `refresh()`.
+
+The `ol/source/Vector#refresh()` method now removes all features from the source and triggers a reload of the data from the server. If you were previously using the `refresh()` method to re-render a vector layer, you should instead call `ol/layer/Vector#changed()`.
+
+#### Other changes
+
+##### Allow declutter in image render mode
+
+It is now possible to configure vector tile layers with `declutter: true` and `renderMode: 'image'`. However, note that decluttering will be done per tile, resulting in labels and point symbols getting cut off at tile boundaries.
+Until now, using both options forced the render mode to be `hybrid`.
+
+##### Always load tiles while animating or interacting
+
+`ol/PluggableMap` and subclasses no longer support the `loadTilesWhileAnimating` and `loadTilesWhileInteracting` options. These options were used to enable tile loading during animations and interactions. With the new DOM composition render strategy, it is no longer necessary to postpone tile loading until after animations or interactions.

+## Why is zooming or clicking in the map off/inaccurate?
+
+OpenLayers does not update the map when the container element is resized. This can be caused by progressive updates
+to CSS styles or manually resizing the map. When that happens, any interaction will become inaccurate: the map would zoom in and out, and end up not being centered on the pointer. This makes it hard to do certain interactions, e.g. selecting the desired feature.
+
+There is currently no built-in way to react to element's size changes, as [Resize Observer API](https://developer.mozilla.org/en-US/docs/Web/API/ResizeObserver) is only implemented in Chrome.
+
+There is however an easy to use [polyfill](https://github.com/que-etc/resize-observer-polyfill):
+
+```javascript
+import Map from 'ol/Map';
+import ResizeObserver from 'resize-observer-polyfill';
+
+const mapElement = document.querySelector('#map')

-title: Blend Modes
-shortdesc: Shows how to change the canvas compositing / blending mode in post- and precompose eventhandlers.
-docs: >
-  <p>This example shows how to change the canvas compositing / blending mode in
-  post- and precompose event handlers. The Canvas 2D API provides the property
-  <code>globalCompositeOperation</code> with which one can influence which
-  composition operation will be used when drawing on the canvas. The various
-  options are well described on the <a href="https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/globalCompositeOperation">MDN
-  documentation page</a>.</p>
-
-  <p>In this example three circles on the corners of an equilateral triangle are
-  drawn with red, green or blue styles respectively. By setting the
-  <code>globalCompositeOperation</code> you can change how these colors turn out
-  when they are combined on the map.</p>
-
-  <p>You can select an operation in the select-field and you can also control
-  which layers will be affected by the chosen operation through the layer
-  checkboxes.</p>

-tags: "webgl, icon, sprite, vector, point"
+  This example shows how to use `ol/renderer/webgl/PointsLayer` to render
+    a very large amount of sprites. The above map is based on a dataset from the National UFO Reporting Center: each
+    icon marks a UFO sighting according to its reported shape (disk, light, fireball...). The older the sighting, the redder
+    the icon.
+
+  A very simple sprite atlas is used in the form of a PNG file containing all icons on a grid. Then, the `texCoordCallback`
+    option of the `ol/renderer/webgl/PointsLayer` constructor is used to specify which sprite to use according to the sighting shape.
+
+  The dataset contains around 80k points and can be found here: https://www.kaggle.com/NUFORC/ufo-sightings
