 - Fix babel/env not picking the correct browserslist configuration during development. When running `docusaurus start`, `process.env.NODE_ENV` is now consistently set to `development`.
 - Ensure routes config generation to be more consistent in ordering. Nested routes should be placed last in routes.js. This will allow user to create `src/pages/docs.js` to create custom docs page for `/docs` or even `src/pages/docs/super.js` to create page for `/docs/super/`;

 - Prioritize `@docusaurus/core` dependencies/ node_modules over user's node_modules. This fix a bug whereby if user has core-js@3 on its own node_modules but docusaurus depends on core-js@2, we previously encounter `Module not found: core-js/modules/xxxx` (because core-js@3 doesn't have that).
 - Fix a bug where docs plugin add `/docs` route even if docs folder is empty. We also improved docs plugin test coverage to 100% for stability before working on docs versioning. ([#1912](https://github.com/facebook/Docusaurus/issues/1912))
 
-### Performance Improvement
+#### Performance Improvement
 
 - Reduce memory usage consumption. ([#1900](https://github.com/facebook/Docusaurus/issues/1900))
 - Significantly reduce main bundle size and initial HTML payload on production build. Generated files from webpack is also shorter in name. ([#1898](https://github.com/facebook/Docusaurus/issues/1898))
 - Simplify blog metadata. Previously, accessing `/blog/post-xxx` will request for next and prev blog post metadata too aside from target post metadata. We should only request target post metadata. ([#1908](https://github.com/facebook/Docusaurus/issues/1908))

 - Convert sitemap plugin to TypeScript. ([#1894](https://github.com/facebook/Docusaurus/issues/1894))
