# 2.0.6

* Fixes an issue where forward merging was not checking that the merge candidate
  was safe to merge (either contains no vendor prefixes,
  or the same vendor prefixes).

# 2.0.5

* Replaced PostCSS' `cloneBefore` with custom clone method to handle `null`
  values properly.

# 2.0.4

* Fixes a crash when cloning a `null` object property (thanks to @JMoxey).

# 2.0.3

* Fixed an issue where the module was incorrectly merging across `@font-face`
  at-rules.

# 2.0.2

* Fixed an issue where keyframes with the same name were being merged together
  incorrectly.

# 2.0.1

* Fixed a crash when `rule.nodes` was not defined.

# 2.0.0

* Upgraded to PostCSS 5.

# 1.3.6

* Minor boost in performance with reduced stringify passes.

# 1.3.5

* Improves merging of adjacent rules with identical selectors.

# 1.3.4

* Fixes an issue where in some cases, non-adjacent rule merging was being
  performed.

# 1.3.3

* Fixes an issue where the wildcard hack (`*zoom: 1`) was being propagated to
  other properties erroneously.
* Better merging logic in some cases.

# 1.3.2

* Fixes a behaviour in which comment nodes were being processed by the
  partial declaration merging logic.

# 1.3.1

* Fixes a behaviour in which rule adjacent forward nodes were not being type
  checked before they were merged.
* Compatibility fixes for the PostCSS plugin guidelines.

# 1.3.0

* Better support for merging properties without the existance of a shorthand
  override.
* Can now 'merge forward' adjacent rules as well as the previous 'merge behind'
  behaviour, leading to better compression.

# 1.2.2

* Fixed an issue where the plugin crashed if node.parent was undefined.

# 1.2.1

* Fixed a bug where media queries were being merged when their parameters were
  different.

# 1.2.0

* Now uses the PostCSS `4.1` plugin API.

# 1.1.1

* Bugfix of last release, now difference is calculated in both directions.

# 1.1.0

* Less eager moving of properties, to avoid cases where moving a longhand
  property would allow a shorthand property to override it.

# 1.0.0

* Initial release.
