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 nownormalizeWhitespace
.reduceBackgroundRepeat
is nownormalizeRepeatStyle
.reduceDisplayValues
is nownormalizeDisplayValues
.reducePositions
is nownormalizePositions
.reduceTimingFunctions
is nownormalizeTimingFunctions
.styleCache
is nowrawCache
.
When excluding transforms, we now have an
exclude
option (in 3.x this was nameddisable
). Similarly, thesafe
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 tofalse
fromtrue
.postcss-normalize-url
:stripWWW
set tofalse
fromtrue
.
-
cssnano now does not accept the
sourcemap
shortcut option; please refer to the PostCSS documentation on sourcemaps. Thequickstart.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-inprocess
method exposed on each PostCSS plugin. The new signature iscssnano.process(css, postcssOpts, cssnanoOpts)
, in 3.x it wascssnano.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 bypostcss-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 thecaniuse-db
dependency is much smaller thanks tocaniuse-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 loadingpostcss-reporter
orpostcss-browser-reporter
in your plugins list. - Prepares support for
grid
identifier reduction by adding it to the list of optimisations turned off whenoptions.safe
is set totrue
. - Adds support for normalizing
unicode-range
descriptors. Values will be converted when the code matches0
&f
in the same place on both sides of the range. So,u+2000-2fff
can be converted tou+2???
, butu+2100-2fff
will be left as it is.
3.9.1
- Resolves an integration issue with
v3.9.0
, whereundefined
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 toinline list-item
rather thaninline-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 exampleblock flow
can be simplified toblock
.
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 uniqid3.0.0
.
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 & thebackground
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
becomesmin-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 thesteps
timing function. - Added the
perspective-origin
property to the list of supported properties transformed by thereduce-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 thebackground
shorthand property.
3.5.0
- Adds a new optimisation path which can minimise keyword values for
background-position
and thebackground
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 renamessafe
internally toisSafe
.
3.3.1
- Unpins postcss-colormin from
2.1.2
, as the2.1.3
&2.1.4
patches had optimization regressions that are now resolved in2.1.5
.
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)
becomestranslateZ(0)
.
3.2.0
- cssnano no longer converts
outline: none
tooutline: 0
, as there are some cases where the values are not equivalent (thanks to @TrySound). - cssnano no longer converts for example
16px
to1pc
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 totrue
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
toturn
& 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 release2.5.0
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.

names. The old options (such as
merge
&fonts
) will be removed in3.0
.

- 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.
