karmen/node_modules/cssnano/CHANGELOG.md

3.10.0

• cssnano will no longer console.warn any messages when using deprecated options; these are now sent to PostCSS. You will be able to see them if you use a PostCSS runner with built-in messages support, or alternately by loading postcss-reporter or postcss-browser-reporter in your plugins list.
• Prepares support for grid identifier reduction by adding it to the list of optimisations turned off when options.safe is set to true.
• Adds support for normalizing unicode-range descriptors. Values will be converted when the code matches 0 & f in the same place on both sides of the range. So, u+2000-2fff can be converted to u+2???, but u+2100-2fff will be left as it is.

3.9.1

• Resolves an integration issue with v3.9.0, where undefined values would attempt to be parsed.

3.9.0

• Adds a new option to normalize wrapping quotes for strings & joining multiple-line strings into a single line. This optimisation can potentially reduce the final gzipped size of your CSS file.

3.8.2

• Resolves an issue where display: list-item inline flow would be normalized to inline list-item rather than inline-list-item (thanks to @mattbasta).

3.8.1

• Adds a quick start file for easy integration with Runkit. Try cssnano online at https://runkit.com/npm/cssnano.

3.8.0

• Adds support for normalizing multiple values for the display property. For example block flow can be simplified to block.

3.7.7

• Further improves CSS mixin handling; semicolons will no longer be stripped from rules as well as declarations.

3.7.6

• Resolves an issue where the semicolon was being incorrectly stripped from CSS mixins.

3.7.5

• Resolves an issue where the safe flag was not being persisted across multiple files (thanks to @techmatt101).

3.7.4

• Improves performance of the reducePositions transform by testing against hasOwnProperty instead of using an array of object keys.
• Removes the redundant indexes-of dependency.

3.7.3

• Unpins postcss-filter-plugins from 2.0.0 as a fix has landed in the new version of uniqid.

3.7.2

• Temporarily pins postcss-filter-plugins to version 2.0.0 in order to mitigate an issue with uniqid 3.0.0.

3.7.1

• Enabling safe mode now turns off both postcss-merge-idents & postcss-normalize-url's stripWWW option.

3.7.0

• Added: Reduce background-repeat definitions; works with both this property & the background shorthand, and aims to compress the extended two value syntax into the single value syntax.
• Added: Reduce initial values for properties when the actual initial value is shorter; for example, min-width: initial becomes min-width: 0.

3.6.2

• Fixed an issue where cssnano would crash on steps(1).

3.6.1

• Fixed an issue where cssnano would crash on steps functions with a single argument.

3.6.0

• Added postcss-discard-overridden to safely discard overridden rules with the same identifier (thanks to @Justineo).
• Added: Reduce animation/transition timing functions. Detects cubic-bezier functions that are equivalent to the timing keywords and compresses, as well as normalizing the steps timing function.
• Added the perspective-origin property to the list of supported properties transformed by the reduce-positions transform.

3.5.2

• Resolves an issue where the 3 or 4 value syntax for background-position were being incorrectly converted.

3.5.1

• Improves checking for background-position values in the background shorthand property.

3.5.0

• Adds a new optimisation path which can minimise keyword values for background-position and the background shorthand.
• Tweaks to performance in the core module, now performs less AST passes.
• Now compiled with Babel 6.

3.4.0

• Adds a new optimisation path which can minimise gradient parameters automatically.

3.3.2

• Fixes an issue where using options.safe threw an error when cssnano was not used as part of a PostCSS instance, but standalone (such as in modules like gulp-cssnano). cssnano now renames safe internally to isSafe.

3.3.1

• Unpins postcss-colormin from 2.1.2, as the 2.1.3 & 2.1.4 patches had optimization regressions that are now resolved in 2.1.5.

3.3.0

• Updated modules to use postcss-value-parser version 3 (thanks to @TrySound).
• Now converts between transform functions with postcss-reduce-transforms. e.g. translate3d(0, 0, 0) becomes translateZ(0).

3.2.0

• cssnano no longer converts outline: none to outline: 0, as there are some cases where the values are not equivalent (thanks to @TrySound).
• cssnano no longer converts for example 16px to 1pc by default. Length optimisations can be turned on via {convertValues: {length: true}}.
• Improved minimization of css functions (thanks to @TrySound).

3.1.0

• This release swaps postcss-single-charset for postcss-normalize-charset, which can detect encoding to determine whether a charset is necessary. Optionally, you can set the add option to true to prepend a UTF-8 charset to the output automatically (thanks to @TrySound).
• A safe option was added, which disables more aggressive optimisations, as a convenient preset configuration (thanks to @TrySound).
• Added an option to convert from deg to turn & vice versa, & improved minification performance in functions (thanks to @TrySound).

3.0.3

• Fixes an issue where cssnano was removing spaces around forward slashes in string literals (thanks to @TrySound).

3.0.2

• Fixes an issue where cssnano was removing spaces around forward slashes in calc functions.

3.0.1

• Replaced css-list & balanced-match with postcss-value-parser, reducing the module's overall size (thanks to @TrySound).

3.0.0

• All cssnano plugins and cssnano itself have migrated to PostCSS 5.x. Please make sure that when using the 3.x releases that you use a 5.x compatible PostCSS runner.
• cssnano will now compress inline SVG through SVGO. Because of this change, interfacing with cssnano must now be done through an asynchronous API. The main process method has the same signature as a PostCSS processor instance.
• The old options such as merge & fonts that were deprecated in release 2.5.0 were removed. The new architecture allows you to specify any module name to disable it.
• postcss-minify-selectors' at-rule compression was extracted out into postcss-minify-params (thanks to @TrySound).
• Overall performance of the module has improved dramatically, thanks to work by @TrySound and input from the community.
• Improved selector merging/deduplication in certain use cases.
• cssnano no longer compresses hex colours in filter properties, to better support old versions of Internet Explorer (thanks to @faddee).
• cssnano will not merge properties together that have an inherit keyword.
• postcss-minify-font-weight & postcss-font-family were consolidated into postcss-minify-font-values. Using the old options will print deprecation warnings (thanks to @TrySound).
• The cssnano CLI was extracted into a separate module, so that dependent modules such as gulp-cssnano don't download unnecessary extras.

2.6.1

• Improved performance of the core module functionOptimiser.

2.6.0

• Adds a new optimisation which re-orders properties that accept values in an arbitrary order. This can lead to improved merging behaviour in certain cases.

2.5.0

• Adds support for disabling modules of the user's choosing, with new option names. The old options (such as merge & fonts) will be removed in 3.0.

2.4.0

• postcss-minify-selectors was extended to add support for conversion of ::before to :before; this release removes the dedicated postcss-pseudoelements module.

• Consolidated postcss-minify-trbl & two integrated modules into postcss-merge-longhand.

2.2.0

• Replaced integrated plugin filter with postcss-filter-plugins.
• Improved rule merging logic.
• Improved performance across the board by reducing AST iterations where it was possible to do so.
• cssnano will now perform better whitespace compression when used with other PostCSS plugins.

2.1.1

• Fixes an issue where options were not passed to normalize-url.

2.1.0

• Allow postcss-font-family to be disabled.

2.0.3

• cssnano can now be consumed with the parentheses-less method in PostCSS; e.g. postcss([ cssnano ]).
• Fixes an issue where 'Din' was being picked up by the logic as a numeric value, causing the full font name to be incorrectly rearranged.

2.0.2

• Extract trbl value reducing into a separate module.
• Refactor core longhand optimiser to not rely on trbl cache.
• Adds support for ch units; previously they were removed.
• Fixes parsing of some selector hacks.

• Wraps all core processors with the PostCSS 4.1 plugin API.

2.0.0

• Adds removal of outdated vendor prefixes based on browser support.
• Addresses an issue where relative path separators were converted to backslashes on Windows.
• cssnano will now detect previous plugins and silently disable them when the functionality overlaps. This is to enable faster interoperation with cssnext.
• cssnano now exports as a PostCSS plugin. The simple interface is exposed at cssnano.process(css, opts) instead of cssnano(css, opts).
• Improved URL detection when using two or more in the same declaration.
• node 0.10 is no longer officially supported.

1.4.3

• Fixes incorrect minification of background:none to background:0 0.

1.4.2

• Fixes an issue with nested URLs inside url() functions.

1.4.1

• Addresses an issue where whitespace removal after a CSS function would cause rendering issues in Internet Explorer.

1.3.3

• Fixes incorrect minification of border:none to border:0 0.

1.3.2

• Improved selector minifying logic, leading to better compression of attribute selectors.
• Improved comment discarding logic.

• Fixed a bug where a CSS function keyword inside its value would throw an error.

1.2.0

• 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.
• Selector re-ordering now happens last in the chain of plugins, to help clean up merged selectors.
