### Upgrading from version 1.0

Options and config settings have changed. However, you need not to worry about your CSS files as all directives are backward-compatible. This is a summary of what's changed:

- New Options:

  - `autoRenameStrict` (default: `false`) to apply auto rename only when a pair exists.
  - `blacklist` to prevent execution of certain directives.
  - `clean` (default: `true`), to remove directives from output CSS.
  - `processUrls` (default: `false`) to control URL updates. You can also target specific node types using an object literal. e.g. `{'atrule': true, 'decl': false}`.

- Updated Options:

  - `autoRename` new default is `false`.
  - `stringMap`:
    - added `priority` attribute to control maps execution order.
    - added `exclusive` attribute, which determines if a map execution should stop iterating over other maps.
    - dropped `'west-east'` map from the default map collection.

- Removed Options:

  - `enableLogging`, still warnings and errors are reported directly to postcss.
  - `minify`, it wasn't actual minification after all!
  - `swapLeftRightInUrl`, `swapLtrRtlInUrl` and `swapWestEastInUrl` in favor of `processUrls` option.
  - `preserveComments`, comments inside declaration values will always be preserved.
  - `preserveDirectives`, in favor of `clean` option.

- Constructor arguments `rules`, `declarations` and `properties` are now replaced with `plugins`.
