Bun Blog2025-10-22 18:110 views

Fixes 103 issues (addressing 172 👍). 2× faster bun build on macOS for symlink-heavy projects, source maps preserve legal comments, and --format=cjs now inlines import.meta; bun test adds global vi, --pass-with-no-tests, and --only-failures; .npmrc :email auth support, faster installs when no peer deps, selective hoisting for isolated installs (publicHoistPattern/hoistPattern), and fs/promises FileHandle.readLines(); numerous bundler/transpiler fixes (external sourcemaps in Bun.build({ compile:true }), --bytecode with import.meta, Windows react-jsxdev); reliability fixes across install/pm/pack, bunx, Node.js compatibility improvements, and numerous bug fixes.
