Codeowner Actions

Tick each box once done. Ticking the last box — "The release is ready for Release Management review" — starts the Release Management review.

• Update the CHANGELOG

  What to do:

  • Copy all API-consumer-relevant changes from the provided list into the appropriate Breaking changes / Added / Changed / Fixed / Removed sections for each API. List breaking changes both in Breaking changes and in their normal change category.
  • Do not copy administrative, tooling-only, or internal maintenance changes unless they affect API consumers.
  • For each API, fill the CHANGELOG against the stated comparison target, following the release-type rules at the top of the CHANGELOG.

• Document deferred validation warnings (and hints)

  What to do:

  • Check the CAMARA Validation comment on this PR for warnings and hints.
  • For each warning you do not fix, document it in an issue: include a copy of the validation summary line(s) and the reason the fix is deferred.
  • Document in the same way any validation hint that is applicable to the API and needs to be fixed later.
  • You may group several findings into one issue or split them across issues — either is fine.
  • List the documenting issue(s) in a comment on this PR.
  • Note: documenting deferred warnings is optional but recommended for alpha pre-releases, and mandatory for rc pre-releases and public releases.

• The release is ready for Release Management review

  Check that:

  • All mandatory release assets for the declared status(es) are present (see the table below "Required release assets per API status" by expanding the arrow);
  • API documentation and test cases are adequate for the target status.

  Tick this box to confirm readiness and to start the Release Management review.

The only remaining hint is not to be fixed as that definition comes from the artifact in Commonalities

The CHANGELOG for geofencing-subscriptions 0.6.0-rc.2 lists no breaking changes, but #437 declares two, and oasdiff between r4.1 and the snapshot confirms them: two error codes added to createGeofencingSubscription (400 OUT_OF_RANGE, 422 MULTIEVENT_COMBINATION_TEMPORARILY_NOT_SUPPORTED). The API is at initial status (0.y.z), so the changes are allowed, but they need to be listed under Breaking changes and under Changed. #437 also removes error codes that cannot occur; OUT_OF_RANGE on the list and callback 400 responses was added in 0.6.0-rc.1 and is now reverted to the 0.5.0 state. Suggestions inline.

location-retrieval and location-verification: oasdiff reports no wire-level changes against r4.1, so the single Changed entry for each is accurate.

The remaining S-313 hint needs no deferral issue.

BTW: as I contributed some of the fixes of this release it would make sense to get another Release Management reviewer involved here for the final approval. @tanjadegroot @eric-murray?
