v1.15.0

This release delivers two critical security patches, adds runtime support for Deno and Bun, and includes significant CI hardening, documentation improvements, and routine dependency updates.

⚠️ Important Changes

• Deprecation: url.parse() usage has been replaced to address Node.js deprecation warnings. If you are on a recent version of Node.js, this resolves console warnings you may have been seeing. (#10625)

🔒 Security Fixes

• Proxy Handling: Fixed a no_proxy hostname normalisation bypass that could lead to Server-Side Request Forgery (SSRF). (#10661)
• Header Injection: Fixed an unrestricted cloud metadata exfiltration vulnerability via a header injection chain. (#10660)

🚀 New Features

• Runtime Support: Added compatibility checks and documentation for Deno and Bun environments. (#10652, #10653)

🔧 Maintenance & Chores

• CI Security: Hardened workflow permissions to least privilege, added the zizmor security scanner, pinned action versions, and gated npm publishing with OIDC and environment protection. (#10618, #10619, #10627, #10637, #10666)
• Dependencies: Bumped serialize-javascript, handlebars, picomatch, vite, and denoland/setup-deno to latest versions. Added a 7-day Dependabot cooldown period. (#10574, #10572, #10568, #10663, #10664, #10665, #10669, #10670, #10616)
• Documentation: Unified docs, improved beforeRedirect credential leakage example, clarified withCredentials/withXSRFToken behaviour, HTTP/2 support notes, async/await timeout error handling, header case preservation, and various typo fixes. (#10649, #10624, #7452, #7471, #10654, #10644, #10589)
• Housekeeping: Removed stale files, regenerated lockfile, and updated sponsor scripts and blocks. (#10584, #10650, #10582, #10640, #10659, #10668)
• Tests: Added regression coverage for urlencoded Content-Type casing. (#10573)

v1.14.0

This release focuses on compatibility fixes, adapter stability improvements, and test/tooling modernisation.

⚠️ Important Changes

• Breaking Changes: None identified in this release.
• Action Required: If you rely on env-based proxy behaviour or CJS resolution edge-cases, validate your integration after upgrade (notably proxy-from-env v2 alignment and main entry compatibility fix).

🚀 New Features

• Runtime Features: No new end-user features were introduced in this release.
• Test Coverage Expansion: Added broader smoke/module test coverage for CJS and ESM package usage. (#7510)

🐛 Bug Fixes

• Headers: Trim trailing CRLF in normalised header values. (#7456)
• HTTP/2: Close detached HTTP/2 sessions on timeout to avoid lingering sessions. (#7457)
• Fetch Adapter: Cancel ReadableStream created during request-stream capability probing to prevent async resource leaks. (#7515)
• Proxy Handling: Fixed env proxy behavior with proxy-from-env v2 usage. (#7499)

v1.15.0 — April 7, 2026

This release delivers two critical security patches targeting header injection and SSRF via proxy bypass, adds official runtime support for Deno and Bun, and includes significant CI security hardening.

🔒 Security Fixes

• Header Injection (CRLF): Rejects any header value containing \r or \n characters to block CRLF injection chains that could be used to exfiltrate cloud metadata (IMDS). Behavior change: headers with CR/LF now throw "Invalid character in header content". (#10660)

• SSRF via no_proxy Bypass: Introduces a shouldBypassProxy helper that normalises hostnames (strips trailing dots, handles bracketed IPv6) before evaluating no_proxy/NO_PROXY rules, closing a gap that could cause loopback or internal hosts to be inadvertently proxied. (#10661)

🚀 New Features

• Deno & Bun Runtime Support: Added full smoke test suites for Deno and Bun, with CI workflows that run both runtimes before any release is cut. (#10652)

🐛 Bug Fixes

• Node.js v22 Compatibility: Replaced deprecated url.parse() calls with the WHATWG URL/URLSearchParams API across examples, sandbox, and tests, eliminating DEP0169 deprecation warnings on Node.js v22+. (#10625)

🔧 Maintenance & Chores

• CI Security Hardening: Added zizmor GitHub Actions security scanner; switched npm publish to OIDC Trusted Publishing (removing the long-lived NODE_AUTH_TOKEN); pinned all action references to full commit SHAs; narrowed workflow permissions to least privilege; gated the publish step behind a dedicated npm-publish environment; and blocked the sponsor-block workflow from running on forks. (#10618, #10619, #10627, #10637, #10641, #10666)

• Docs: Clarified HTTP/2 support and the unsupported httpVersion option; added documentation for header case preservation; improved the beforeRedirect example to prevent accidental credential leakage. (#10644, #10654, #10624)

• Dependencies: Bumped picomatch, handlebars, serialize-javascript, vite (×3), denoland/setup-deno, and 4 additional dev dependencies to latest versions. (#10564, #10565, #10567, #10568, #10572, #10574, #10663, #10664, #10665, #10669, #10670)
