Blob and File constructors now follow Web IDL conversion rules (
aead708)
Node now converts Blob/File constructor arguments in Web IDL order, including inherited dictionary members and File.lastModified conversion, and avoids invoking user getters or species constructors while copying data. It also treats detached parts as empty and tightens brand checks, which brings Node closer to browser behavior and closes observable edge cases.
Crypto caches digests and reuses HMAC contexts (
1eaaeee, 3295b92, 75c42e9, 1a2b511)
Crypto now keeps per-environment digest caches for synchronous operations and reuses HMAC templates in createHmac(), reducing repeated OpenSSL provider lookups. The accompanying tests cover cache invalidation across FIPS mode changes and confirm duplicated HMAC contexts stay independent.
HTTP parser batches body chunks per execute call (
36452f1)
The C++ HTTP parser now buffers body spans and delivers them to JS once per execute() instead of once per chunk, cutting C++↔JS crossings for chunked uploads. This should improve throughput for bodies delivered in many small pieces.
Inspector is blocked during snapshot building (
5e893ce)
Node now rejects --inspect, --inspect-brk, and --inspect-wait when --build-snapshot is in use, matching newer V8 restrictions. The runtime and docs were updated so snapshot builds fail fast instead of hitting a debugger-related V8 limitation later.
Querystring and URLSearchParams percent-encoding gets faster (
544340a, 8337f97)
Latin-1 escape sequences are now precomputed in querystring.escape(), and URLSearchParams#getAll() uses indexed appends. These are focused throughput improvements for common serialization and lookup paths.
HTTP/2 compat push responses now handle stream errors (
4830c11)
Pushed Http2ServerResponse streams now get error handling attached before the callback runs, preventing unhandled errors when a peer refuses a push. Applications that use response.createPushResponse() no longer need to race their own listener attachment to avoid crashes.
