2.1.1

• Fixes a compatibility issue with modular-css - now the module will only use the raw selector value if it equal to the 'cleaned' selector value.

2.1.0

• Adds support for converting between similar :nth-child selectors. For example, :nth-child(1) can be converted to :first-child, and p:nth-last-child(2n + 1) converts to p:nth-last-child(odd).

2.0.7

• Fixes a regression where postcss-minify-selectors would transform [title=""] into [title=] (thanks to @arperry).

2.0.6

• Performance tweaks; now calls Node#toString() ~50% less often, removed dead branches, extracted each node type into a separate transformer function.
• Resolves an issue where extraneous whitespace around a case-insensitive attribute selector ([href="foo" i]) would not be removed.

2.0.5

• Updated postcss-selector-parser to 2.0.0.

2.0.4

• Now compiled with babel 6.

2.0.3

• Fixed an issue where [a="-"] was incorrectly minified to [a=-].

2.0.2

• Fixed a crash with Polymer mixins; now the module will pass through any selector string with a trailing colon.

2.0.1

• Replaced javascript-natural-sort with alphanum-sort (thanks to @TrySound).

2.0.0

• Upgraded to PostCSS 5.
• At-rule parameter minification was extracted out of this module into postcss-minify-params (thanks to @TrySound).

1.4.7

• Further performance improvements by using less postcss-selector-parser iterations.
