## Upgrade notes
### Next release
#### `ol.Map#forEachFeatureAtPixel` and `ol.Map#hasFeatureAtPixel` parameters have changed
If you are using the layer filter of one of these methods, please note that you now have to pass in the layer filter via an `ol.AtPixelOptions` object. If you are not using the layer filter the usage has not changed.
Old syntax:
```
map.forEachFeatureAtPixel(pixel, callback, callbackThis, layerFilterFn, layerFilterThis);
map.hasFeatureAtPixel(pixel, layerFilterFn, layerFilterThis);
```
New syntax:
```
map.forEachFeatureAtPixel(pixel, callback, {
layerFilter: layerFilterFn
});
map.hasFeatureAtPixel(pixel, {
layerFilter: layerFilterFn
});
```
To bind a function to a this, please use the bind method of the function (See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
This change is due to the introduction of the `hitTolerance` parameter which can be passed in via this `ol.AtPixelOptions` object, too.
### v3.20.0
#### Use `view.animate()` instead of `map.beforeRender()` and `ol.animation` functions

#### Use `ol.proj.getPointResolution()` instead of `projection.getPointResolution()`
The experimental `getPointResolution` method has been removed from `ol.Projection` instances. Since the implementation of this method required an inverse transform (function for transforming projected coordinates to geographic coordinates) and `ol.Projection` instances are not constructed with forward or inverse transforms, it does not make sense that a projection instance can always calculate the point resolution.
