[dependabot]

Bumps js-yaml from 5.2.2 to 5.3.0.

Changelog

Sourced from js-yaml's changelog.

[5.3.0] - 2026-08-14

This release focuses on reworking the documentation and making small architectural improvements before moving forward.

Added

• Added completely new documentation.
• Exported DUMP_SCHEMA, the default schema used by the dumper.
• Added YAMLException.throwAt() for throwing an error at a source position.

Changed

• Changed flat constant exports to grouped exports: EVENT_ID, SCALAR_STYLE, COLLECTION_STYLE, and CHOMPING_MODE, along with their value types. The old exports are still preserved, but deprecated.
• Made identify mandatory for custom tag definitions. Use identify: () => false for load-only tags.

Deprecated

• Deprecated flat constant exports. Use grouped ones instead.

Removed

• Removed the MERGE_KEY export (not used anymore after last fixes).

Fixed

• Validate << sequence items at merge time, so aliased merge sources are checked too.
• Resolve << outside of a mapping key as the plain string '<<', matching v4, instead of leaking an internal symbol into the result.

[5.2.3] - 2026-08-01

Fixed

• Prevent prototype fallback when resolving tags and mapping entries, #782.
• Resolve !!timestamp years 0000-0099 correctly, #775.
• Preserve implicit null mapping values before document markers and reject unpaired mapping event streams, #784.
• Preserve folded scalar values with tab-indented lines when round-tripping a parsed AST through present(); dump() and loading are unaffected, #780.
