📝 Walkthrough

Walkthrough

The package manifest adds a js-yaml resolution override and updates the direct dependency from ^4.3.1 to ^4.3.2.

Align js-yaml versions package.json	The resolutions block pins js-yaml to ^4.3.2. The dependency entry uses the same version.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 593c3

This update forces all transitive consumers onto js-yaml 4.3.2, which may break packages still relying on removed v3 APIs and cause runtime failures. The change is mergeable with explicit owner awareness and compatibility verification for those consumers.

Poem

A rabbit checked the YAML line
Both versions now align just fine
The lockstep pins sit neat
With carrots by their feet
And hops through green builds shine

Scope the js-yaml resolution to compatible consumers.

The root Yarn resolutions entry can replace the ^3.x requests from @istanbuljs/load-nyc-config and cosmiconfig@3.1.0 with v4. js-yaml v4 removes v3 APIs such as safeLoad(). Upgrade these consumers or retain a patched v3 resolution for them.

does not force v4 onto `@istanbuljs/load-nyc-config` and cosmiconfig@3.1.0, which
require v3 APIs; either upgrade those consumers to v4-compatible versions or add
a targeted patched v3 resolution while preserving v4 for compatible consumers.
