Highlights
Upgraded to oasdiff v1.23.0
Every action (breaking, changelog, diff, pr-comment, validate) now runs on oasdiff v1.23.0: nullability changes are recognized in all three equivalent forms (the nullable keyword, the 3.1 type array, and the null oneOf wrapping) and reported as a single, correctly-leveled finding, for bodies, properties, and parameters, in both directions. Wrapping a $ref'd schema in oneOf: [{type: "null"}, ...] no longer produces false breaking errors. See the nullability guide.
No workflow changes are required: existing steps pick up the newer engine automatically on your next run.
Full Changelog: v0.1.5...v0.1.6
