### [`v3.0.0`](https://togithub.com/sapphiredev/plugins/blob/HEAD/packages/hmr/CHANGELOG.md#sapphireplugin-hmr300---2023-12-05) [Compare Source](https://togithub.com/sapphiredev/plugins/compare/@sapphire/plugin-hmr@2.0.3...@sapphire/plugin-hmr@3.0.0) #### ↩️ Revert - "refactor(register): cleanup unnecessary side effect imports of index" ([c2af242](https://togithub.com/sapphiredev/plugins/commit/c2af24269956132237988d94e4d94719b2cd442c)) #### 🏠 Refactor - **register:** Cleanup unnecessary side effect imports of index ([dede596](https://togithub.com/sapphiredev/plugins/commit/dede596ae22ceec2700dd860287a1260f092b502)) #### 🚀 Features - Split ESM and CJS bundles for proper ESM and CJS loading ([#​512](https://togithub.com/sapphiredev/plugins/issues/512)) ([d9aa006](https://togithub.com/sapphiredev/plugins/commit/d9aa006ff8c7f78a613dcca605d3353b992b7a46)) - 💥 **BREAKING CHANGE:** This ensures that the plugins will properly load the either only ESM or only CJS files. This is done by outputting dist/cjs and dist/esm folders. This requires [@​sapphire/framework](https://togithub.com/sapphire/framework) v5.x!
