less 5.0.0-alpha.1 on Node.js NPM

Alpha Release

This Less 5 alpha is a Jess-powered compiler rewrite for early testing, not a drop-in Less 4.x replacement yet.

Highlights:

CSS nesting is preserved by default.
Less-style ampersand joining for BEM-style modifiers and similar selector patterns is still supported.
Nested and extended selector output may use modern selectors such as :is(); selector compatibility remains part of the alpha feedback surface.
Browser compilation is not included in this alpha; a new browser build mechanism will be introduced in a future alpha.

See CHANGELOG.md for the current supported surface and work-in-progress areas.

npm install less@5.0.0-alpha.1 --tag alpha

Or:

npm install less@alpha
