-### Migrating from 2.x to 3.x
-
-Version `3.x` introduced changes to configuring source maps. Accordingly, if you don't use the source map options you should be able to upgrade seamlessly. If you do use source maps, see below.
-
-#### Removed options
-
-* `sourceMappingURL` - This is calculated automatically now
-* `sourceMapPrefix` - No longer necessary for the above reason
-
-#### Changed options
-
-* `sourceMap` - Only accepts a `Boolean` value. Generates a map with a default name for you
-* `sourceMapRoot` - The location of your sources is now calculated for you when `sourceMap` is set to `true` but you can set manual source root if needed
-
-#### New options
-
-* `sourceMapName` - Accepts a string or function to change the location or name of your map
-* `sourceMapIncludeSources` - Embed the content of your source files directly into the map
-* `expression` - Accepts a `Boolean` value. Parse a single expression (JSON or single functions)
-* `quoteStyle` - Accepts integers `0` (default), `1`, `2`, `3`. Enforce or preserve quotation mark style.
-
 ### Options
 
 This task primarily delegates to [UglifyJS2][], so please consider the [UglifyJS documentation][] as required reading for advanced configuration.
