 ### Next release
 
+### v4.2.0
+
+#### Return values of two `ol.style.RegularShape` getters have changed
+
+To provide a more consistent behaviour the following getters now return the same value that was given to constructor:
+
+`ol.style.RegularShape#getPoints` does not return the double amount of points anymore if a radius2 is set.
+
+`ol.style.RegularShape#getRadius2` will return `undefined` if no radius2 is set.
+
+### v4.1.0
+
+#### Adding duplicate layers to a map throws
+
+Previously, you could do this:
+```js
+map.addLayer(layer);
+map.addLayer(layer);
+```
+
+However, after adding a duplicate layer, things failed if you tried to remove that layer.
+
+Now, `map.addLayer()` throws if you try adding a layer that has already been added to the map.
+
+#### Simpler `constrainResolution` configuration
+
+The `constrainResolution` configuration for `ol.interaction.PinchZoom` and `ol.interaction.MouseWheelZoom`
+can now be set directly with an option in `ol.interaction.defaults`:
+```js
+ol.interaction.defaults({
+  constrainResolution: true
+});

+
+## Summary
+
+The v4.1.0 release includes features and fixes from 91 pull requests.
+
+#### Interactive overview map
+
+The extent rectangle on the overview map can now be dragged to control the view for the main map.
+
+#### Setting min and max zoom for a view
+
+You can now change the min or max zoom for a view after it has been created.  This can be useful if you want to limit how far out users can zoom based on changes in viewport width (use `view.setMinZoom()` for this).
+
+#### Adding duplicate layers to a map throws
+
+Previously, you could do this:
+```js
+map.addLayer(layer);
+map.addLayer(layer);
+```
+
+However, after adding a duplicate layer, things failed if you tried to remove that layer.

+# 4.2.0
+
+## Summary
+
+The v4.2.0 release includes features and fixes from 87 pull requests.
+
+#### New `movestart` event on `ol.Map`
+
+The map now has a `movestart` event, as countarpart to the already existing `moveend` event.
+
+#### New `moveTolerance` option in `ol.Map`
+
+Some touch devices do not play well with OpenLayers's way of detecting clicks. To overcome this, a new `moveTolerance` option was introduced, so users can override the 1 pixel threshold above which a touch-release sequence won't be considered a click any more.
+
+#### Support for multiple layers in `ol.format.TopoJSON`
+
+With the new `layerName` and `layers` options, applications can extract the layer as additional attribute for vector features from `ol.format.TopoJSON`. This can especially be useful for styling vector tile layers.
+
+#### New `tileJSON` option for `ol.source.TileJSON`
+
+Like `ol.source.TileUTFGrid`, `ol.source.TileJSON` now also has a `tileJSON` option to configue it with inline TileJSON instead of a TileJSON URL.
+
+#### New `ol.format.filter.during` filter
+
+Although OpenLayers has no support for WFS v2.0, we added `ol.format.filter.during` for the `During` temporal operator.
+
+#### Improved vector tile rendering at non-native resolutions
+
+The vector tile renderer now uses an internal tile grid for all resolutions to cache pre-rendered tiles, even if the tile source does not have tiles for the viewed resolution. This improves rendering quality and performance.
+
+#### New `insertVertexCondition` for `ol.interaction.Modify`
+
+Applications can now control whether a vertex will be inserted into the modified geometry. This makes it easier to modify custom geometries.
+
+#### New `callback` option for `ol.View#fit()`
+
+To allow applications to perform custom actions when an animation associated with `ol.View#fit()` is completed, that method now has a new `callback` option.
+
+#### New `ol.View#getInteracting()` getter
+
+Like `ol.View#getAnimating()` returns `true` during a view animation, `ol.View#getInteracting()` returns `true` while users are interacting with the view.
+
+#### New `hasZ` option for `ol.format.WFS#writeTransaction()`
+
+When the new `hasZ` option is set to `true`, 3D coordinates will be preserved and encoded when writing a WFS transaction.
+
+#### New `wrapX` option for `ol.source.Stamen`
+
+Like other tile sources, `ol.source.Stamen` now also has a `wrapX` option, which allows applications to turn off wrapping the world in x direction.
+
+#### Label support for `ol.Graticule`
+
+The `ol.Graticule` component has several new options to add and control the output of labels. To turn on labelling, configure `ol.Graticule` with `showLabels: true`. The new options to control label formatting are `lonLabelFormatter`, `latLabelFormatter`, `lonLabelPosition` and `latLabelPosition`.
+
+#### Return values of two `ol.style.RegularShape` getters have changed
+
+To provide a more consistent behaviour the following getters now return the same value that was given to constructor:
+
+`ol.style.RegularShape#getPoints` does not return the double amount of points anymore if a radius2 is set.
+
+`ol.style.RegularShape#getRadius2` will return `undefined` if no radius2 is set.
