Breaking: Drops support for Node 0.12, we now require at least Node 4.
Breaking: Update PostCSS to 6.0.0.
Breaking: Removes the deprecated options from version 2.2.0.
2.6.1
Resolves an issue where IE hacks were being removed from 0 values
(thanks to @Justineo).
2.6.0
Added clamping of the values for the shape-image-threshold property, using
the same logic as introduced in version 2.5.0.
2.5.0
Added clamping of the values for the opacity property to the 0-1 range.
For example, this will convert opacity: 1.1 to opacity: 1.
2.4.1
Resolves an issue where the units would be stripped from zero values in
custom properties (thanks to @jgerigmeyer).
2.4.0
Added a precision option to enable rounding of decimal places for
px values.
2.3.6
Resolves an issue with the last patch where height: 0em was not being
converted to height: 0.
2.3.5
Resolves an issue where certain properties inside @keyframes rules would
break animation in IE due to the percentage being stripped. Now, the
percentage is preserved for these properties.
2.3.4
Does not convert height:0% to height:0 (and the same for max-height), as
they produce different results.
2.3.3
Updates postcss-value-parser to version 3 (thanks to @TrySound).
2.3.2
Fixed a regression where 0% in color functions was being transformed to 0
(thanks to @TrySound).
2.3.1
Fixed a behaviour where 0deg was being converted to 0.
2.3.0
Added an option to convert between turn & deg (thanks to @TrySound).
2.2.1
Fixes a behaviour where the module would remove units from zero values inside
calc functions (thanks to @marek-saji & @TrySound).
2.2.0
Renames opts.convertLength & opts.convertTime to
opts.length & opts.time; the old options will now print deprecation
warnings (thanks to @TrySound).
2.1.0
Adds options to enable/disable unit conversion for time & length values.
2.0.1
Bump postcss-value-parser to 2.0.2.
2.0.0
Upgraded to PostCSS 5.
1.3.1
Fixes an issue where the module would convert values in gradient/url functions
since 1.3.0.
1.3.0
Converted the module to use ES6.
balanced-match, css-list & some integrated code has been replaced with
postcss-value-parser; reducing the number of moving parts in this module, and
providing a more futureproof way of parsing CSS numeric values.
1.2.5
Fixes an issue where uppercase units (such as PX) were being deleted.
1.2.4
Fixes convert not px or ms
1.2.3
Adds support for ch units; previously they were removed.
Upgrades css-list to 0.1.0, code tidied up.

negative value transforms.

1.1.1
Fixes an issue where trailing zeroes were not being removed in
values that were not 0 (thanks to @TrySound).
1.1.0
Adds support for removing leading zeroes from rem values
(thanks to @tunnckoCore).
1.0.3
Fixed a bug where filenames were being incorrectly transformed.
1.0.2
Fixed a bug where 1. and .0 were not being optimised to 1 and 0,
respectively.
1.0.1
Fixed a bug where undefined would be stringified as the unit value, if the
value did not have a unit.
