#### `ol.source.VectorTile` no longer requires a `tileGrid` option
By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22. If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
Before:
```js
var source = new ol.source.VectorTile({
tileGrid: ol.tilegrid.createXYZ({tileSize: 512, maxZoom: 22}),
url: url
});
```
After:
```js
var source = new ol.source.VectorTile({
url: url
});
```
If you need to change the max zoom level, you can pass the source a `maxZoom` option. If you need to change the tile size, you can pass the source a `tileSize` option. If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
#### `ol.interaction.Modify` deletes with `alt` key only #### `ol.interaction.Modify` deletes with `alt` key only
To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex. If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option. For example, to allow deletion on a single click with no modifier keys, configure the interaction like this: To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex. If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option.
