Release builds now optimize startup function order (
150f9cf)
Deno’s release pipeline now does a two-pass build on supported Linux/macOS targets: it traces startup execution from an unstripped binary, generates a function order file, then relinks the release binary with that order and verifies the result. This is a substantial startup-performance change that should improve binary cold-start behavior while keeping the order artifact reproducible and checked in CI.
AbortSignal.any() now matches Node’s validation behavior (
9dcb61d)
AbortSignal.any() now tags its argument-validation failures with Node-compatible error codes and validates array members up front to produce the expected signals[i] is not of type AbortSignal. error. That tightens Node compatibility for a commonly used API.
WebIDL and TextDecoder errors now carry Node-style codes (111ca9b)
Several WHATWG validation errors now attach Node error codes like ERR_INVALID_ARG_VALUE, ERR_INVALID_ARG_TYPE, ERR_MISSING_ARGS, and ERR_ENCODING_NOT_SUPPORTED. This makes node:* consumers see the same err.code values they would get on Node instead of generic TypeErrors.
util.diff is now implemented for Node compat (04dcb7e)
Deno’s Node polyfills now include util.diff, backed by Myers diff logic. That fills in a missing public API used by Node-compatible packages and tests.
WebCrypto deriveBits(…, 0) now returns an empty buffer (89e420c)
SubtleCrypto.deriveBits() now correctly treats a requested length of 0 as an empty result for PBKDF2 and HKDF instead of throwing OperationError. This fixes a WebCrypto spec compliance gap and avoids a crash path in the underlying derivation code.
Upgrade output test tolerates delta-upgrade logging (84c5999)
The stable upgrade spec now accepts the extra line printed during delta upgrades. This is a test-only adjustment to keep the upgrade flow stable as the release process changes.
Other misc changes
- Node/WebCrypto compat test expectations updated for a number of existing message/code differences.
- CI/test config updates to ignore or add several Node compat cases.
- Startup-order tooling, docs, and workflow scaffolding added for the new perf pipeline.
