Highlights

LightningCSS minimizer

In v0.7.4 Rspack provides a new CSS minimizer which uses Lightning CSS under the hood, for now you can enable it by optimization.minimizer, and in Rspack v1.0, it will be enabled by default.

And here are two very useful features powered by the new LightningCSS minimizer:

• removeUnusedLocalIdents: during minification, it removes the CSS declarations corresponding to the unused-symbols. This allows Rspack to work with CSS modules' tree shaking to remove unused CSS declarations corresponding to exports (previously, it would only remove the JS exports).
• browserslist: with this options minification will also performs downgrading. If the postcss-loader was previously used only for downgrading, it can be removed.

Checkout our docs for more details.

Compatible with worker-loader

In v0.7.4 Rspack is compatible with worker-loader, which is usually used by some older projects, so this is provided only as a temporary solution to facilitate these older projects migration to Rspack, checkout our docs for more details.
