17.0.0

Added

• Added eslint-plugin-unused-imports to the base ESLint config to flag unused imports and variables.
• Added extraEntries and extraPlugins options to the Webpack project config so projects can extend entry points and plugins without overriding the full config.
• Added at-rule-no-unknown to the Stylelint config with the SCSS at-rule allowlist to surface unknown at-rules without breaking SCSS files.

Changed

• Updated all dependencies to their latest versions.
• Updated React ESLint setting from a pinned version 18 to detect.
• Updated store.js reducer cases (SET_STYLE, SET_STYLE_BY_INDEX, UNSET_STYLE_BY_INDEX) to return new state objects instead of mutating existing state.
• Updated getCookie helper to parse cookies via document.cookie.split and decodeURIComponent for safer value handling.
• Updated attributes.js, options.js, and related helpers with WeakMap-based caching for componentName lookups and other performance refinements.
• Updated webpack/helpers.mjs to expose readManifestJson and convertDataToSass helpers, reducing duplicate manifest reads.

Removed

• Removed the global jQuery and $ Webpack ProvidePlugin injection. Projects that relied on globally injected jQuery must import it explicitly.
• Removed the process.browser Webpack DefinePlugin value in favor of typeof window: '"object"'. Code that referenced process.browser must be updated.
• Removed unused React import from css-variables.js and cleaned up other unused imports across components.

Fixed

• Fixed the MJS Webpack rule regex (/\.m?js/ → /\.m?js$/) so non-JS paths containing js are no longer matched.
• Downgraded ESLint to ^9.39.4 to restore compatibility with the current plugin ecosystem.
