## @radix-ui/react-accordion 1

### Performance

- Bundlers can drop unused components more effectively, because component parts are marked pure and use named render functions. (1.2.17) — [release notes](https://github.com/radix-ui/primitives/blob/925c88b773bb32aecf1b52a296a1a21ba7a720b9/packages/react/accordion/CHANGELOG.md#1217)

### Tooling

- Republished through CI so the package includes a provenance attestation. (1.2.18) — [release notes](https://github.com/radix-ui/primitives/blob/925c88b773bb32aecf1b52a296a1a21ba7a720b9/packages/react/accordion/CHANGELOG.md#1218)
