Bun v1.4.2 patches two regressions introduced in v1.4.1: a bun build variable name collision that broke Elysia imports with a SyntaxError, and an AsyncLocalStorage memory leak affecting timers and promises created inside store.exit() or nested store.run(). It also fixes a worker_threads 'online' event ordering bug that caused @discordjs/ws to hang, adds CMYK/YCCK JPEG decoding support to Bun.Image, pulls in roughly 350 upstream WebKit/JavaScriptCore commits fixing Intl, TypedArray, and Proxy correctness issues, and resolves several crash and hang bugs including a rare JIT crash, a musl GC crash, a bun install panic, and a double-close file descriptor bug on Linux
