# 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.
|
|
|
|
# 2.3.0
|
|
|
|
* 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.
|
|
* Fixes an issue where embedded base 64 data was being converted as if it were
|
|
a URL.
|
|
|
|
# 2.0.1
|
|
|
|
* Add `postcss-plugin` keyword to package.json.
|
|
* 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.
|
|
|
|
# 1.4.0
|
|
|
|
* Adds support for removal of unused `@keyframes` and `@counter-style` at-rules.
|
|
* comments: adds support for user-directed removal of comments, with the
|
|
`remove` option (thanks to @dmitrykiselyov).
|
|
* comments: `removeAllButFirst` now operates on each CSS tree, rather than the
|
|
first one passed to cssnano.
|
|
|
|
# 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.
|
|
|
|
# 1.3.1
|
|
|
|
* Fixes crash on undefined `decl.before` from prior AST.
|
|
|
|
# 1.3.0
|
|
|
|
* Added support for bundling cssnano using webpack (thanks to @MoOx).
|
|
|
|
# 1.2.1
|
|
|
|
* 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.
|
|
|
|
# 1.1.0
|
|
|
|
* Now can merge identifiers such as `@keyframes` and `@counter-style` if they
|
|
have duplicated properties but are named differently.
|
|
* Fixes an issue where duplicated keyframes with the same name would cause
|
|
an infinite loop.
|
|
|
|
# 1.0.2
|
|
|
|
* Improve module loading logic (thanks to @tunnckoCore).
|
|
* Improve minification of numeric values, with better support for `rem`,
|
|
trailing zeroes and slash/comma separated values
|
|
(thanks to @TrySound & @tunnckoCore).
|
|
* Fixed an issue where `-webkit-tap-highlight-color` values were being
|
|
incorrectly transformed to `transparent`. This is not supported in Safari.
|
|
* Added support for viewport units (thanks to @TrySound).
