+# 6.1.1
+
+Hot on the heels of OpenLayers 6.x, this patch release includes a few fixes for existing functionality.  There should be nothing special needed to upgrade an application from 6.x to 6.1.1. See the 6.0.0 release notes for details on upgrading from an older version.

+# 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.

+title: Tracing around a polygon
+shortdesc: Example of setting up a draw interaction to easily snap to an existing feature.
+docs: >
+  This example showcases how the draw interaction API can be set up to make snapping along
+  an existing geometry easier while preserving topology, which is sometimes called "tracing".
+  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
+  the currently drawn feature.
+  This leverages the `appendCoordinates` method of the `ol/interaction/Draw` interaction.

+  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.
