# 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).
# 1.5.0
* Added support for converting pseudo elements with double colon syntax to
the single colon syntax.
# 1.4.7
* Further performance improvements by using less postcss-selector-parser
iterations.
# 1.4.6
* Bump normalize-selector to `0.2.0`, decreases overall package weight.
* Speed up node iteration by calling `eachInside` once rather than twice.
# 1.4.5
* Update normalize-selector to cut down package weight.
# 1.4.4
* Fixed an integration issue with postcss-font-magician.
# 1.4.3
* Fixed an issue where `.from` was transformed to `0%`.
# 1.4.2
* Bump dependencies.
* Fixes for PostCSS plugin guidelines.
# 1.4.1
* Fixes incorrect deduplication of pseudo selector rules.
# 1.4.0
* Update to postcss-selector-parser to greatly improve parsing logic.
# 1.3.1
* Fixes a crash when nothing was passed to `node-balanced`.
# 1.3.0
* Now uses the PostCSS `4.1` plugin API.
# 1.2.1
* Passes original test case in issue 1.
# 1.2.0
* Does not touch quoted values in attribute selectors.
* No longer will mangle values such as `2100%` in keyframes.
# 1.1.0
* Now minifies `from` to `0%` and `100%` to `to` in keyframe declarations.
# 1.0.0
* Initial release.
