Node cluster support lands on Unix (
04e5db2)
Deno now implements node:cluster on Unix, wiring up IPC handle passing and the cluster worker/primary polyfills. This unlocks 68 additional Node compatibility tests and is a meaningful step toward fuller Node runtime parity.
HTTP request bodies skip the stream wrapper when already buffered (6cf098d)
req.json()/.text()/.bytes() can now take a fast path when Hyper has already buffered the whole body, avoiding ReadableStream setup and related resource churn. The change also adds a new Rust op to drain buffered bodies non-blockingly, which should improve common small-request server performance.
Node crypto gains more Node-compatible key handling (
19bd3d8, 
c86f92b, fa01b38, 509eb54, 8ec2df3, 1f0b5c8)
A cluster of crypto fixes brought node:crypto closer to Node.js semantics: CryptoKey inputs are now accepted in key-creation APIs, JWK input paths are handled more consistently, and several PEM/PKCS#8/cipher edge cases were corrected. These changes unlock multiple compat tests and fix real interoperability gaps around key import/export and signing.
Node type/runtime defaults now include Node built-ins (
05f52c3, bfc3c88)
Type checking now includes the Node lib by default, and timer APIs return NodeJS.Timeout instead of number. That better matches Deno's runtime behavior and should reduce friction for codebases that rely on Node globals and timer typings.
Node module resolution now handles nested package.json safely (
5197c79)
The CommonJS resolver was adjusted to treat nested package.json files inside node_modules as part of the package root, while still preserving traversal protection. This fixes resolution for packages with subpath layouts and closes a module-resolution edge case.
More Node polyfills and lazy-loading perf work (e84fc15, ce3598e, bf42857, a317222)
Large parts of the Node polyfill layer were converted to lazy-loaded scripts, reducing eager startup cost and breaking up some dependency cycles. Separate perf work also moved ext/http, ext/process, ext/kv, and ext/webgpu sources onto the same lazy-loading path.
Other misc changes
- Reverted a flaky AES-128-ECB crypto fix.
- Added HTTP header/socket behavior fixes for specific Node compat tests.
- Tweaked update/lockfile behavior so
deno update --lockfile-onlypreserves config. - Minor CI/test config updates and one flaky Node compat test disablement.
