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

bun test --isolate and --parallel
Two new flags for bun test that dramatically speed up large test suites:
--isolate runs each test file in a fresh global environment within the same process. Between files Bun drains microtasks, closes sockets, cancels timers, kills subprocesses, and creates a clean global object. A VM‑level transpilation cache means shared dependencies are only parsed once.
--parallel[=N] distributes test files across up to N worker processes (defaults to CPU count). Files are partitioned for cache locality, idle workers steal work, and output remains identical to serial execution.

bun test --shard
Split test files across multiple CI runners with the new --shard flag (syntax M/N). Files are sorted by path and distributed round‑robin. Works with --changed and --randomize. Invalid inputs produce clear errors.

bun test --changed
Runs only test files affected by git changes by building the import graph and filtering to changed dependencies. Supports uncommitted changes, specific commits/branches, and works with --watch for continuous re‑filtering.

bun install streams tarballs to disk
bun install now extracts package tarballs while downloading, using only in‑flight HTTP chunks plus fixed buffers. Integrity hashing runs incrementally. Streaming extraction is enabled by default; can be disabled with BUN_FEATURE_FLAG_DISABLE_STREAMING_INSTALL=1.

Faster bun install with isolated linker
In a peer‑heavy monorepo, bun install --linker=isolated reduces install time dramatically (e.g., from 20.5s to 2.4s).

Source maps use up to 8x less memory
Source map representation rearchitected to a compact bit‑packed binary format (~2.4 B per mapping vs ~20 B). Memory usage drops from ~11 MB to ~2.9 MB for a large TypeScript project. Decoding cost is near zero; lookups ~6 % slower.

Bun’s runtime uses 5% less memory
Upgraded mimalloc to v3 and added libpas scavenger support on Windows & Linux, reducing baseline memory usage and fixing hangs/crashes.

Upgraded JavaScriptCore engine
Merged 1,316 upstream commits into WebKit’s JavaScriptCore, bringing numerous performance improvements and bug fixes.

Performance improvements from upstream
- Inline cache for array.length = N
- Inline cache for undefined, true, false, null as property keys
- String length folding in DFG/FTL
- toUpperCase intrinsic JIT‑intrinsified
- String#indexOf single‑character fast path
- Redundant mov removed from await/yield bytecode
- Cached default date formatters
- Wider bulk copy in GC‑safe memcpy/memmove
- SIMD‑accelerated equalIgnoringASCIICase
- SIMD fast path for identifier parsing

Faster addEventListener, dispatchEvent, and DOM events
Cherry‑picked ~270 upstream WebKit commits improve event system and promise internals.

File streaming improvements
Response(Bun.file(path)) and static routes now stream incrementally on SSL and Windows, reducing memory usage for large files.

Range Request Support in Bun.serve()
Bun.serve() now handles HTTP Range requests for file‑backed responses, returning 206 Partial Content or 416 as appropriate. Supports suffix, open‑ended, and standard RFC 9110 ranges.

Up to 5.5x faster gzip compression with zlib‑ng
Upgraded to zlib‑ng 2.3.3 with SIMD acceleration. Significant speedups for gzipSync, deflate, createGzip streams, etc.

Faster array iteration in Bun’s internals
Array iteration up to 1.43× faster for common cases by reading elements directly from JSC’s butterfly memory.

SHA3 support in WebCrypto and node:crypto
Adds SHA3‑224/256/384/512 to crypto.createHash, crypto.createHmac, crypto.getHashes, crypto.subtle.digest, and crypto.subtle.sign/verify.

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
