Maintainer changes

This version was pushed to npm by GitHub Actions, a new releaser for postcss since your current version.

Updates axios from 1.13.5 to 1.18.1

Release notes

Sourced from axios's releases.

v1.18.1 — June 21, 2026

This release focuses on Node HTTP adapter fixes, safer AxiosError serialisation, runtime/type correctness fixes, documentation updates, and dependency maintenance.

🐛 Bug Fixes

• AxiosError Serialisation: Made AxiosError#cause non-enumerable to prevent circular JSON serialisation failures when errors include nested causes. (#10913)
• Node HTTP Adapter: Guarded socket.setKeepAlive for proxy agent streams, accepted path-only URLs when socketPath is configured, deferred environment proxy handling to Node, and explicitly passed maxBodyLength through to follow-redirects. (#10917, #10930, #10942, #10993)
• Runtime and Type Correctness: Fixed several runtime crashes, type definition mismatches, and incorrect error handling paths. (#10959, #11021)
• AxiosURLSearchParams: Switched the encoder callback to an arrow function so encoder.call(this) receives the AxiosURLSearchParams instance correctly. (#11019)

🔧 Maintenance & Chores

• Documentation: Documented sensitive headers and status transition behaviour, prepared cleaned-up docs, added Deno install instructions, and clarified that request data is request-specific (#11007, #11010, #11023, #11025)

• Dependencies: Bumped vite, rollup, form-data, js-yaml, and multer across the root project, docs, smoke tests, and module test workspaces. (#11011, #11012, #11013, #11014, #11015, #11016, #11017, #11026)

Full Changelog

v1.18.0 — June 13, 2026

This release hardens redirect and URL handling, improves the validateStatus configuration semantics, and includes updates to documentation, dependencies, and release metadata.

🔒 Security Fixes

• Redirect Header Safety: Added Node HTTP adapter support for stripping caller-specified sensitive headers on cross-origin redirects, helping prevent custom auth headers such as API keys from leaking to another origin. (#10892)

• URL And Request Hardening: Rejects malformed http: and https: URLs that omit // with ERR_INVALID_URL, while tightening prototype-pollution-safe config reads, stream size limits, FormData depth handling, data URL sizing, and local NO_PROXY matching. (#11000)

🐛 Bug Fixes

• Status Validation: Added transitional.validateStatusUndefinedResolves so applications can opt in to treating validateStatus: undefined like the option was omitted, while validateStatus: null remains the explicit way to accept every status. (#10899)

🔧 Maintenance & Chores

• Documentation: Published the v1.17.0 release notes, fixed a changelog typo, clarified the package update PR policy, and marked the proxy request config as Node.js-only in the advanced docs. (#10984, #10988, #10992, #10995)

• Dependencies: Bumped @babel/core, @babel/preset-env, @commitlint/cli, @commitlint/config-conventional, @rollup/plugin-babel, @rollup/plugin-commonjs, @vitest/browser, @vitest/browser-playwright, eslint, lint-staged, rollup, vitest, and actions/checkout. (#10989, #10996, #10997)

• Release Metadata: Prepared the 1.18.0 release by updating package metadata and the runtime VERSION value. (#11003)

Full Changelog

v1.17.0 — June 1, 2026

This release adds Node HTTP zstd decompression, hardens config and release workflows, and fixes authentication, header, proxy, and type-handling regressions.

🔒 Security Fixes

• Config Hardening: Guarded socketPath, params, and paramsSerializer reads with own-property checks to prevent inherited prototype values from affecting request behavior, including SSRF-sensitive paths. (#10901, #10922)
• Release Publishing: Switched the publish workflow to npm staged publishing for safer, auditable package releases with provenance. (#10926)

🚀 New Features

• HTTP Compression: Added Node HTTP adapter support for zstd response decompression, with transitional.advertiseZstdAcceptEncoding controlling whether zstd is advertised in Accept-Encoding. (#6792, #10920)

🐛 Bug Fixes

• Authentication Handling: Restored Basic auth on same-origin Node redirects while continuing to strip credentials cross-origin, and aligned the fetch adapter with HTTP adapter behavior for URL-embedded Basic auth. (#10929, #10896)

• fix(IndexedCollection): has(index) on a lazy Seq of unknown size now checks index existence instead of searching for a value equal to the index #2203
• [TypeScript]: reduce/reduceRight without an initial value now infer the result type from the collection's values when the reducer returns a value (e.g. list.reduce((a, b) => a + b) infers number), matching Array#reduce. Previously an explicit type argument was required. #2205

5.1.6

• fix(reverseFactory): read reversedSequence.size in __iterator instead of this #2196

5.1.5

• Fix Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in immutable

Updates js-yaml from 4.1.1 to 4.3.0

Changelog

Sourced from js-yaml's changelog.

4.3.0, 3.15.0 - 2026-06-27

Security

• Backported maxTotalMergeKeys option.

[5.2.0] - 2026-06-26

Added

• Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.
• Added maxAliases (-1) loader option to limit the number of YAML aliases per document.

Removed

• maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

Fixed

• Round-trip of integers with exponential form (>= 1e21)

[5.1.0] - 2026-06-23

Added

• Collection tags can finalize an incrementally populated carrier into a different result value.

Changed

• [breaking] quoteStyle now selects the preferred quote style; use the restored forceQuotes option to force quoting non-key strings.

[5.0.0] - 2026-06-20

Added

• Added named exports for schemas, tags, parser events and AST utilities.
• Reworked JSON_SCHEMA and CORE_SCHEMA with spec-compliant scalar resolution rules, and added YAML11_SCHEMA.
• Added realMapTag for lossless mappings with non-string and complex keys. Object-based mappings now reject complex keys instead of stringifying them.
• Added dump() transform option for changing the generated AST before rendering.
• Added dump() options seqInlineFirst, flowBracketPadding, flowSkipCommaSpace, flowSkipColonSpace, quoteFlowKeys, quoteStyle and tagBeforeAnchor.
• Added formal data layers (events and AST) for modular data pipelines.
  • Added low-level parser (to events), presenter and visitor APIs.
• Added the YAML Test Suite to the test set.

Changed

• See the migration guide for upgrade notes.
• Rewritten in TypeScript and reorganized the public API around flat named exports.
