7.1 “Universitas litterarum”

on GitHub

Autoprefixer 7.1 brings unicode-bidi support, -webkit-appearance to Edge and fix intrinsic widths prefixes in Grid Layout.

unicode-bidi

Autoprefixer 7.1 will add prefixes for isolate, plaintext and isolate-override values in unicode-bidi:

.foo {
  unicode-bidi: -webkit-isolate;
  unicode-bidi: isolate;
}

Edge and -webkit-appearance

Prefixes sometime could be very strange. Edge started to support appearance property with a prefix. But because of many only-for-Safari websites it supports -webkit-appearance instead of -ms-appearance.

Autoprefixer 7.1 knows it and will generate -webkit-appearance even if you set only "last 1 Edge version" in browserslist config.

Intrinsic Widths

min-content, stretch and other Intrinsic sizes was fixed in grid-template-columns and other Grid Layout properties.

.foo {
  grid-template-columns: minmax(100px, -webkit-min-content);
  grid-template-columns: minmax(100px, min-content);
}

Browserslist in info()

By accident Browserslist 1 loaded config from current working dir if file path was missed. In Browserslist 2 we fixed it and now you must specify path to file in explicit way.

It is not a problem for Autoprefixer user, because Autoprefixer takes CSS file path from PostCSS.
But autoprefixer.info() stopped to load conifg in 7.0. In 7.1 we added from option to info().

Set the path to your CSS file and info() will show what prefixes and why it will added to this CSS file:

autoprefixer.info({ from: './scr/app.css' })
