September 2025 brought major performance improvements to the Vite ecosystem. Rolldown achieved 10-45% faster builds on macOS and Windows through optimized I/O and file metadata retrieval, plus 20-30% faster source map builds. Binary size was reduced by 200KB. Oxlint saw 5-50% linting speed gains in real-world codebases, added a new rule with auto-fix, and fixed a memory leak. Vitest gained browser mode debugging support in VS Code and upcoming Playwright trace viewer integration. Community highlights include Framer adopting Rolldown in production, Qwik achieving 4x faster builds by switching from Rollup to Rolldown, date-fns switching to Oxlint, and Deno's Fresh 2.0 adding a Vite plugin. Upcoming events include ViteConf 2025 (Oct 9-10) and JSConf North America.
