What's New

Deno platform fixes BigInt stats and socket handling; Node platform adds Unix socket support and HTTP redaction

Breaking Changes

  • Deno: `FileSystem.File.Info` metadata fields changed from `number` to `bigint`
  • Deno: `FileSystem.File.Info` stats fields are now `Option<bigint>`

New Features

  • Deno: Added `Path.resolveWithin(root, input)` utility
  • Node: Added `NodeHttpClient` options for unix sockets and mutual TLS
  • Node: Added `UrlParams.redact` and `UrlParams.redactUrl` utilities

Improvements

  • Deno: Enhanced filesystem watcher with installation notifications
  • Node: Redacted sensitive query values and URL credentials in HTTP spans
  • Node: Updated dependencies

Bug Fixes

  • Deno: Fixed `FileSystem.watch` to prefer caller-provided backend
  • Deno: Fixed `DenoSocket` dying on writer release after close

Upgrade Notes

When upgrading `platform-deno`, update code handling file stats to expect `bigint` instead of `number`. When upgrading `platform-node`, note that AWS signature headers are now redacted via `UrlParams` rather than `Headers`.
