process.memoryUsage().heapUsed now reflects the latest full GC (
91cdf15)
Bun now reports heapUsed from the most recent collection instead of sticking to the last eden GC value. This fixes incorrect memory stats in full-GC and no-JIT modes, where heapUsed could be stale, zero, or even larger than heapTotal.
Shell rm -rf no longer aborts on deep paths (8000230)
Bun.$ rm now handles entries deeper than PATH_MAX as an error instead of panicking the process. That turns an uncatchable crash into a normal failure for recursive deletes on very deep trees.
SQL pool accounting stays balanced when a connection dies (254b065)
When a reserved SQL connection closes unexpectedly, Bun now keeps the pool’s query counters and reservation state in sync. This fixes cases where a dropped connection could leave the pool thinking a slot was still occupied or miscounted, breaking later scheduling and cleanup.
Bundler stops emitting dead import() chunks (
4673c48)
With --splitting, chunks referenced only from code eliminated by tree shaking are no longer emitted. That reduces unnecessary output and fixes a correctness issue where dead dynamic imports could still force real chunks into the build.
Valkey retry/close handling was tightened up (
13845e1)
The reconnect path now explicitly cancels stale timers, distinguishes terminal disconnects from retrying states, and avoids double-closing sockets during retry windows. This makes connection failure, close, and reconnect behavior much more reliable under racey shutdown and retry scenarios.
Valkey socket lifetime handling was reworked (85c8983)
Bun moved the keep-alive ref release to the close-event entry so the ref is dropped at the right moment, before user-level close handling runs. This fixes lifecycle bugs where Valkey sockets could outlive their intended close path or settle incorrectly during reconnects.
WebView now cleans up views after browser death (4855666)
If the browser process disappears, orphaned Bun.WebView instances are now rejected/closed instead of hanging forever. That prevents stuck promises and leaked view slots after crashes, EOF, or explicit shutdown.
node:crypto shake digests no longer SIGABRT on huge output lengths (87ac50c)
SHAKE digests with output lengths above 2^31 now fail safely instead of aborting the process. That aligns Bun with Node for large-but-valid digest sizes and removes a hard crash from the crypto API.
Buffer#copy now handles oversized offsets correctly (b938280)
Offsets at or above Number.MAX_SAFE_INTEGER no longer silently turn into zero. This fixes incorrect copies and brings Bun’s behavior in line with Node’s range checking and return values.
Other misc changes
- Dead-code removal across runtime, bindings, crates, and headers; including a large WebKit text-encoding cleanup and bundled binary size reductions.
- Worker startup no longer eagerly builds and discards fd-backed stdio streams.
Bun.file().arrayBuffer()and child-process output now throw cleanly instead of panicking on >4 GiB / overflow-sized payloads.- Several path-length crash fixes in CLI,
bun test,fs.watch, and shell builtins (mkdir,touch,rm). - NAPI / vm / receiver-conversion fixes for Node compatibility, including
ShadowRealm,util.isError,StringDecoder,fs.Stats, and callbacks. - WebView Windows spawn-path support, stream/direct response abort handling,
bun pm diff,bun install/build dependency cleanup, and assorted test/build updates.
