+# 6.1.0
+
+With 47 pull requests, this release keeps up the momentum of the v6.x effort and brings several bug fixes, performance improvements and new features. In addition to that, we added some missing documentation to our API docs and gave them some usability improvements.
+
+## New features
+
+* A new, performance optimized hit detection API on the layer level, `Layer#getFeatures(pixel)` has been introduced. At this point it is implemented for vector, vector tile and image vector layers, and is recommended when performance is critical, e.g. for hit detection on mouseover.
+* For the WebGLPoints layer, we made several additions to the style expressions system. This includes a `case` operator, support for array and string types, and type checking.

+# 6.2.0
+
+With almost 90 pull requests, this release brings several new features, performance improvements and bug fixes. In addition to that, we once again improved the API documentation and the example pages.
+
+## New features and improvements
+
+* Mousewheel zooming now brings the same user experience as trackpad zooming. One click on the wheel no longer means a jump of a whole zoom level. Instead, depending on the speed of moving the wheel, the user has fine-grained control over zoom increments/decrements.
+* Users now have better control over the initial map viewport when the aspect ratio of the map is different from a specified initial extent.
+* Text rendering has been optimized for decluttering and improved for rotated views. This means lower memory footprint and no more blurry text when the map is rotated. **Note:** Whit this change, the label cache has been deprecated.
+* A new `displacement` option for icon, circle and regular shape styles makes positioning of point symbolizers more flexible.
+* Several improvements have been made to the KML parser for reading styles, bringing the rendered result much closer to Google Earth.
+* OpenLayers is now less aggressive on stopping events and preventing event default behavior. This means that users have more control over events, making it easier to use interactive SVGs as layers and to embed maps on scrollable pages.
+* Vector tile layers now have a `vector` render mode, which brings improved zooming experience for sources with not too much data.
+* We replaced the previous pointer events polyfill to elm-pep, which should work better in web components.
+

-  This example shows how to use `ol/renderer/webgl/PointsLayer` to dynamically filter a large amount
+  This example shows how to use `ol/layer/WebGLPoints` with a literal style to dynamically filter a large amount
     of point geometries. The above map is based on a dataset from the NASA containing 45k recorded meteorite
     landing sites. Each meteorite is marked by a circle on the map (the bigger the circle, the heavier
     the object). A pulse effect has been added, which is slightly offset by the year of the impact.
 
-  Adjusting the sliders causes the objects outside of the date range to be filtered out of the map. This is done using
-    a custom fragment shader on the layer renderer, and by using the `v_opacity` attribute of the rendered objects
-    to store the year of impact.
+  Adjusting the sliders causes the objects outside of the date range to be filtered out of the map. This is done
+    by mutating the variables in the `style` object provided to the WebGL layer. Also note that the last snippet
+    of code is necessary to make sure the map refreshes itself every frame.

+  This example uses the "immediate" rendering API with geometries in geographic coordinates.
+  The immediate rendering API lets you draw styled geometries without adding them to a layer first.
+  Use the `getVectorContext` function to create a rendering context from a render event.  Using the

+  <p>Note: when <code>Single-click</code> is used double-clicks won't select features. This in contrast to <code>Click</code>, where a double-click will both select the feature and zoom the map (because of the <code>DoubleClickZoom</code> interaction). Note that <code>Single-click</code> is less responsive than <code>Click</code> because of the delay it uses to detect double-clicks.</p>
+  <p>In this example, a listener is registered for the Select interaction's <code>select</code> event in order to update the selection status above.

+  When the user clicks on two different points on the Idaho state border,
+  the part of the border comprised between these two points is added to

-    </ul>
-  </p>
+  This example shows how to use a `WebGLPointsLayer` to show a large amount of points on the map.
+  The layer is given a style in JSON format which allows a certain level of customization of the final reprensentation.
+
+  The following operators can be used:
+
+   * Reading operators:
+     * `['get', 'attributeName']` fetches a feature attribute (it will be prefixed by `a_` in the shader)
+       Note: those will be taken from the attributes provided to the renderer
+     * `['var', 'varName']` fetches a value from the style variables, or 0 if undefined
+     * `['time']` returns the time in seconds since the creation of the layer
+     * `['zoom']` returns the current zoom level
+     * `['resolution']` returns the current resolution
+
+   * Math operators:
+     * `['*', value1, value2]` multiplies `value1` by `value2`
+     * `['/', value1, value2]` divides `value1` by `value2`
+     * `['+', value1, value2]` adds `value1` and `value2`
+     * `['-', value1, value2]` subtracts `value2` from `value1`
+     * `['clamp', value, low, high]` clamps `value` between `low` and `high`
+     * `['%', value1, value2]` returns the result of `value1 % value2` (modulo)
+     * `['^', value1, value2]` returns the value of `value1` raised to the `value2` power
+
+   * Transform operators:
+     * `['case', condition1, output1, ...conditionN, outputN, fallback]` selects the first output whose corresponding
+       condition evaluates to `true`. If no match is found, returns the `fallback` value.
+       All conditions should be `boolean`, output and fallback can be any kind.
+     * `['match', input, match1, output1, ...matchN, outputN, fallback]` compares the `input` value against all
+       provided `matchX` values, returning the output associated with the first valid match. If no match is found,
+       returns the `fallback` value.
+       `input` and `matchX` values must all be of the same type, and can be `number` or `string`. `outputX` and
+       `fallback` values must be of the same type, and can be of any kind.
+     * `['interpolate', interpolation, input, stop1, output1, ...stopN, outputN]` returns a value by interpolating between
+       pairs of inputs and outputs; `interpolation` can either be `['linear']` or `['exponential', base]` where `base` is
+       the rate of increase from stop A to stop B (i.e. power to which the interpolation ratio is raised); a value
+       of 1 is equivalent to `['linear']`.
+       `input` and `stopX` values must all be of type `number`. `outputX` values can be `number` or `color` values.
+       Note: `input` will be clamped between `stop1` and `stopN`, meaning that all output values will be comprised
+       between `output1` and `outputN`.
+
+   * Logical operators:
+     * `['<', value1, value2]` returns `true` if `value1` is strictly lower than `value2`, or `false` otherwise.
+     * `['<=', value1, value2]` returns `true` if `value1` is lower than or equals `value2`, or `false` otherwise.
+     * `['>', value1, value2]` returns `true` if `value1` is strictly greater than `value2`, or `false` otherwise.
+     * `['>=', value1, value2]` returns `true` if `value1` is greater than or equals `value2`, or `false` otherwise.
+     * `['==', value1, value2]` returns `true` if `value1` equals `value2`, or `false` otherwise.
+     * `['!=', value1, value2]` returns `true` if `value1` does not equal `value2`, or `false` otherwise.
+     * `['!', value1]` returns `false` if `value1` is `true` or greater than `0`, or `true` otherwise.
+     * `['between', value1, value2, value3]` returns `true` if `value1` is contained between `value2` and `value3`
+       (inclusively), or `false` otherwise.
+
+   * Conversion operators:
+     * `['array', value1, ...valueN]` creates a numerical array from `number` values; please note that the amount of
+       values can currently only be 2, 3 or 4.
+     * `['color', red, green, blue, alpha]` creates a `color` value from `number` values; the `alpha` parameter is
+       optional; if not specified, it will be set to 1.
+       Note: `red`, `green` and `blue` components must be values between 0 and 255; `alpha` between 0 and 1.
+   Values can either be literals or another operator, as they will be evaluated recursively.
+   Literal values can be of the following types:
+    * `boolean`
+    * `number`
+    * `string`
