Bumps js-yaml from 4.1.0 to 4.3.1.

Changelog

Sourced from js-yaml's changelog.

4.3.1 - 2026-07-31

Security

[backport] Remove quadratic complexity from !!omap duplicate key detection.

4.3.0 - 2026-06-27

Added

[backport] Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.

Fixed

Restore umd builds back to es5.

Removed

[backport] maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

[4.2.0] - 2026-06-01

Added

Added docs/safety.md with notes about processing untrusted YAML.

Added maxDepth (100) loader option. Not a problem, but gives a better exception instead of RangeError on stack overflow.

Added maxMergeSeqLength (20) loader option. Not a problem after merge fix, but an additional restriction for safety.

Added sourcemaps to dist/ builds.

Changed

Stop resolving numbers with underscores as numeric scalars, #627.

Switched dev toolchains to Vite / neostandard.

Updated demo.

Reorganized tests.

dist/ files are no longer kept in the repository.

Fixed

Fix parsing of properties on the first implicit block mapping key, #62.

Fix trailing whitespace handling when folding flow scalar lines, #307.

Reject top-level block scalars without content indentation, #280.

Ensure numbers survive round-trip, #737.

Fix test coverage for issue #221.

Fix flow scalar trailing whitespace folding, #307.

Fix digits in YAML named tag handles.

Security

Fix potential DoS via quadratic complexity in merge - deduplicate repeated elements (makes sense for malformed files > 10K).

[3.14.2] - 2025-11-15
