### Minor Changes

- 16c057df: Breaking Change: Performance Optimization for `styled`

  When a component is wrapped in `styled`, Linaria needs to determine if that component is already a styled component. To accomplish this, the wrapped component is included in the list of variables for evaluation, along with the interpolated values used in styles. The issue arises when a wrapped component, even if it is not styled, brings along a substantial dependency tree. This situation is particularly evident when using `styled` to style components from third-party UI libraries.

  To address this problem, Linaria will now examine the import location of the component and check if there is an annotation in the `package.json` file of the package containing the components. This annotation indicates whether the package includes other Linaria components. If there is no such annotation, Linaria will refrain from evaluating the component.

  Please note that this Breaking Change solely affects developers of component libraries. In order for users to style components from your library, you must include the `linaria.components` property in the library's `package.json` file. This property should have a mask that covers all imported files with components. Here's an example of how to specify it:

  ```json
  "linaria": {
    "components": "**/*"
  }
  ```

### Patch Changes

- af5bb92d: The end of support for Node.js 14. Migration to pnpm 8.

## 4.1.0

### Minor Changes

- 77bcf2e7: - 714a8e86: Modify the handling of CSS @ rules in `collect` to only include child rules if critical
  - 1559cfa9: Add support in `collect` for ignoring and blocking classes from the regex for critical CSS extraction

## 4.0.0

### Major Changes

- bc0cbeea: A completely new async mode with native support for Vite, Rollup, esbuild and Webpack resolvers.

  BREAKING CHANGES: Despite the fact, that it should be fully compatible with 3.0 and 2.0 branches, the new version of styles evaluator can have some serious bugs which can make your project unbuildable (however, since there is no runtime, if the build is finished successfully, everything will continue work as it was on 2.0 and 3.0). If you face some problems please let us know and we will fix it as soon as possible.

### Patch Changes

- 8be5650d: The repo has been migrated to PNPM and Turborepo
- ea41d440: New package @linaria/tags that contains all abstract logic for tags processors.
- 4cdf0315: Tagged template-specific logic has been moved from `BaseProcessor` to `TaggedTemplateProcessor`. `BaseProcessor` now can be used to define any type of expressions for zero-runtime transformations, such as `makeStyles` from `@griffel/react`.
