being loaded correctly (thanks to @andyjansson).
|
|
* postcss-minify-params: Resolved an issue with cssnano's handling of the
|
|
`@value` syntax from css-modules to better integrate with css-loader.
|
|
|
|
# 4.0.0-rc.0
|
|
|
|
Since version 4 has been in-development for some time, we thought it would be
|
|
best to release an alpha version so that we could catch any issues before
|
|
the actual release.
|
|
|
|
## Breaking changes
|
|
|
|
* cssnano & its plugins have been upgraded to PostCSS 6.x. Please ensure that
|
|
for optimal results that you use cssnano with a PostCSS 6 compatible runner
|
|
& that any other plugins are also using PostCSS 6.
|
|
* cssnano is now essentially a preset loader and does not contain any built-in
|
|
transforms (instead, it delegates to `cssnano-preset-default` by default).
|
|
Due to the new architecture, it's not possible to exclude asynchronous
|
|
transforms and run it synchronously, unlike in 3.x. Any transforms that
|
|
were "core" modules have now been extracted out into separate packages.
|
|
* Because of the new preset system, cssnano will not accept any transformation
|
|
options; these must be set in the preset. The option names remain mostly the
|
|
same, except some cases where "core" modules have been extracted out:
|
|
|
|
* `core` is now `normalizeWhitespace`.
|
|
* `reduceBackgroundRepeat` is now `normalizeRepeatStyle`.
|
|
* `reduceDisplayValues` is now `normalizeDisplayValues`.
|
|
* `reducePositions` is now `normalizePositions`.
|
|
* `reduceTimingFunctions` is now `normalizeTimingFunctions`.
|
|
* `styleCache` is now `rawCache`.
|
|
|
|
When excluding transforms, we now have an `exclude` option (in 3.x this was
|
|
named `disable`). Similarly, the `safe` option was removed; the defaults
|
|
are now much less aggressive.
|
|
* By default, the following transforms are no longer applied to any input CSS.
|
|
You may see an increased output file size as a result:
|
|
|
|
* `autoprefixer`
|
|
* `postcss-discard-unused`
|
|
* `postcss-merge-idents`
|
|
* `postcss-reduce-idents`
|
|
* `postcss-zindex`
|
|
|
|
Note that you can load `cssnano-preset-advanced` instead which *does* contain
|
|
these transforms.
|
|
* We no longer detect previous plugins to silently exclude our own, and now
|
|
consider this to be an anti-pattern. So `postcss-filter-plugins` was removed.
|
|
* We also changed some options to make the default transforms safer:
|
|
|
|
* `postcss-minify-font-values`: `removeAfterKeyword` set to `false` from `true`.
|
|
* `postcss-normalize-url`: `stripWWW` set to `false` from `true`.
|
|
|
|
* cssnano now does not accept the `sourcemap` shortcut option; please refer
|
|
to the PostCSS documentation on sourcemaps. The `quickstart.js` file included
|
|
with this module will give you a good starting point.
|
|
* `cssnano.process` is no longer a custom method; we use the built-in `process`
|
|
method exposed on each PostCSS plugin. The new signature is
|
|
`cssnano.process(css, postcssOpts, cssnanoOpts)`, in 3.x it was
|
|
`cssnano.process(css, cssnanoOpts)`.
|
|
* We dropped support for Node 0.12, now requiring at least Node 4.
|
|
* Finally, cssnano is now developed as a monorepo, due to the fact that some
|
|
transforms have a lot of grey area/overlap. Due to this, some modules have
|
|
been refactored to delegate responsibility to others, such that duplication
|
|
of functionality is minimized. For instance, `postcss-colormin` will no
|
|
longer compress whitespace or compress numbers, as those are handled by
|
|
`postcss-normalize-whitespace` & `postcss-convert-values` respectively.
|
|
|
|
## Other changes
|
|
|
|
* Due to the PostCSS 6 upgrade, we have been able to reduce usage of custom
|
|
methods, such as node `clone` behaviour. In cases where some utility
|
|
has been used by several plugins it is now a separate package, reducing
|
|
cssnano's footprint.
|
|
* cssnano now makes much better use of Browserslist. `postcss-colormin` &
|
|
`postcss-reduce-initial` were enhanced with different behaviour depending
|
|
on which browsers are passed. And now, the footprint for the `caniuse-db`
|
|
dependency is much smaller thanks to `caniuse-lite` - 7 times smaller as
|
|
of this writing. This makes cssnano much faster to download from npm!
|
|
|
|
# 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

|
|
an infinite loop.
