v0.33.0 — June 13, 2026

This release hardens request config handling and form serialisation, adds Node.js 26 coverage for v0.x, and updates the v0.x release workflow.

🔒 Security Fixes

• Request Config Hardening: Uses own-property reads for nested request options affecting auth, params, proxy, and data handling; adds bounded form serialisation depth checks; normalises nullish Basic Auth credentials; and treats 0.0.0.0 as local for proxy bypass. (#11001)

🚀 New Features

• Node.js 26: Adds Node.js 26 to the v0.x CI and release/publish matrices. (#10937)

🔧 Maintenance & Chores

• Release Publishing: Adopts npm staged publishing for v0.x releases and disables npm caching in CI to make installs and publish jobs more deterministic. (#10936, #10943)
• Changelog: Backfills missing v0.x changelog entries for prior releases. (#10842)
• Release Metadata: Bumps package and internal version metadata for v0.33.0. (#11002)
