- Added source‑map support for JavaScript (including unbundled code) and many new Web APIs such as HTMLRewriter, timers, Blob, fetch clones, atob/btoa, etc., to bun.js.
- Improved performance – bun dev is ~10 % faster on macOS, parsing of long strings and HTML entity codes in JSX up to 70 %/10 % faster, and reduced HMR latency with better syscalls.
- Fixed numerous crashes, memory leaks, UTF‑8 console bugs, async WASM compilation issue, and enhanced error messages (ResolveError/BuildError toString, source‑map error locations).
