# v4.6.0

### Summary

The 4.6 release includes enhancements and fixes from 30 or so pull requests.  Headlining this release, vector layers got new `textBackgroundFill`, `textBackgroundStroke` and `padding` options that can be used to render background boxes for text. `ol.source.ImageVector` is now deprecated and replaced by a more convenient way to render vectors as images: by simply setting `renderMode: 'image'` on the vector layer.

Please note that if you are using `closure-util` to build your OpenLayers based application, it is time to migrate to using the [`ol` package](https://www.npmjs.com/package/ol) and a module bundler like webpack.  OpenLayers has not had a dependency on the Closure Library since the [3.19 release](https://github.com/openlayers/openlayers/releases/tag/v3.19.0); and with the 5.0 release we will be moving completely away from `goog.require` and `goog.provide`, dropping support for `closure-util`, and going with ES modules for our sources.

See the [wiki](https://github.com/openlayers/openlayers/wiki/OpenLayers-v5.x) about upcoming changes in 5.0 and tips on how to upgrade.  We likely won't have another 4.x release before the 5.0 release.  If you're interested in continuing to get feature enhancements in future releases, migrating to the `ol` package now will make the transition easier.


### Upgrade notes

#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`

To update your applications, simply replace `exceedLength` with `overflow`.

#### Deprecation of `ol.source.ImageVector`

Rendering vector sources as image is now directly supported by `ol.layer.Vector` with the new `renderMode: 'image'` configuration option. Change code like this:

```js
new ol.layer.Image({
  source: new ol.source.ImageVector({
    style: myStyle,
    source: new ol.source.Vector({
      url: 'my/data.json',
      format: new ol.format.GeoJSON()
    })
  })
});
```
to:

```js
new ol.layer.Vector({
  renderMode: 'image',
  style: myStyle,
  source: new ol.source.Vector({
    url: 'my/data.json',
    format: new ol.format.GeoJSON()
  })
});
```
