Fixes 82 issues (addressing 381 👍). bun test --parallel, --isolate, --shard, and --changed, bun install streams tarballs to disk using 17x less memory, source maps use 8x less memory, 5.5x faster gzip with zlib-ng, Range request support in Bun.serve(), SHA3 in node:crypto and WebCrypto, ws+unix:// WebSocket client, and many bugfixes and Node.js compatibility improvements

Features
- bun test --isolate runs each test file in a fresh global environment within the same process, draining microtasks, closing sockets, cancelling timers, killing subprocesses, and creating a clean global object between files.
- bun test --parallel[=N] distributes test files across up to N worker processes (default CPU count), partitioning for cache locality and stealing work from idle workers; output remains identical to serial execution.
- bun test --shard=M/N splits test files across CI jobs, sorting by path and distributing round‑robin; works with --changed and --randomize, exits gracefully when a shard has no files.
- bun test --changed runs only test files affected by git changes, building an import graph and filtering to transitive dependents; supports --watch for re‑filtering on every restart.
- bun install streams tarballs to disk: extracts package tarballs while downloading, using only in‑flight HTTP chunks plus fixed buffers, reducing memory usage by ~17x.
- Faster bun install with isolated linker: `bun install --linker=isolated` speeds up installs in peer‑heavy monorepos.
- Source maps use up to 8x less memory: compact bit‑packed binary format (~2.4 B per mapping) replaces full VLQ list, reducing resident size from ~11 MB to ~1.3 MB for large projects.
- Bun’s runtime uses 5% less memory: upgraded mimalloc to v3 and added libpas scavenger support for Windows and Linux, improving baseline usage and reducing hangs/crashes.
- Upgraded JavaScriptCore engine (1,316 upstream commits) with performance improvements such as inline cache for array length, property keys, string length folding, toUpperCase intrinsic, fast path for String#indexOf, redundant mov removal, cached date formatters, wider bulk copy in GC‑safe memcpy, SIMD‑accelerated case‑insensitive comparisons, and SIMD fast path for identifier parsing.
- Faster addEventListener, dispatchEvent, and DOM events via ~270 upstream WebKit commits.
- File streaming improvements in Bun.serve(): Response(Bun.file(path)) now streams incrementally on SSL and Windows, reducing memory usage for large files.
- Range request support in Bun.serve(): automatic handling of `Range` headers for static and dynamic file responses, returning 206 Partial Content or 416 as appropriate.
- Up to 5.5x faster gzip compression with zlib‑ng 2.3.3: SIMD‑accelerated CRC32, Adler32, longest‑match and chunk‑copy operations; benchmarks show 2.5‑5.5× speedups for gzip/deflate.
- Faster array iteration in Bun’s internals: up to 1.43× speedup for common cases by reading elements directly from JSC’s butterfly memory.
- SHA3 support in WebCrypto and node:crypto: SHA3‑224/256/384/512 available via `crypto.createHash`, `crypto.createHmac`, `crypto.subtle.digest`, etc.
- X25519 deriveBits support in SubtleCrypto: full X25519 key agreement implementation, handling small‑order public keys per RFC 7748.
- WebSocket client now supports `ws+unix://` and `wss+unix://` URLs for Unix domain socket connections, with proper Host header and proxy handling.
- Standalone HTML built with `bun build --compile --target browser` now inlines file‑loader assets imported from JavaScript as data URIs.
- `bunx claude` is now an alias for `bunx @anthropic-ai/claude-code`.

Bugfixes
- Node.js compatibility improvements: fixed worker lifecycle crashes, tls.connect host handling, passphrase option crashes, process.ppid caching, --cpu-prof output format, socket.setTimeout spurious timeouts, node:http2.createServer ENABLE_PUSH issue, StringDecoder.write crash, native N‑API module finalizer order, dgram source‑specific membership options, os.freemem on Linux,

Bun v1.1.24 fixes a regression introduced in v1.1.23 that caused the net module to throw an error after upgrading from TCP -> TLS.The tests that would've prevented this regression were being skipped due to a credentials issue after migrating to a new CI provider.To prevent this regression from recurring, we have ensured tests missing credentials in our CI will always fail.There are no release notes for this version, please see the release notes for v1.1.23.Read Bun v1.1.23's release notes on Bun's blog
