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.

Release Management review of the r2.2 snapshot.

CHANGELOG

• Breaking changes are N/A for both APIs, but oasdiff breaking between r2.1 and this snapshot reports:
  • device-data-volume-subscriptions: config.subscriptionDetail became required in the POST /subscriptions request (request-property-became-required)
  • device-data-volume: the max of remainingDataAllowance.value in the POST /retrieve 200 response increased from 1000 to 99999 (response-property-max-increased)
• Under device-data-volume-subscriptions, two entries refer to device-data-volume: the 429 test cases for checkDataVolume and retrieveDataVolume (L72), and "Remove 404 NOT_FOUND from device-data-volume all endpoints" (L92, already listed at L131).
• Missing under Removed for device-data-volume-subscriptions: OUT_OF_RANGE from the 400 response of GET /subscriptions, and INCOMPATIBLE_STATE from the 409 response of POST /subscriptions.

Content findings

Several findings from the r2.1 review (#118) are only partially fixed, and the review found a few new ones. They need fixes on main and are collected in #134 (#135, #136, #137). As this is already the second release candidate, I recommend fixing them before it is published.
