Auto-generated public release notes for August 3, 2026, covering changes merged to airbytehq/airbyte-platform-internal between 2026-07-31 07:00 UTC and 2026-08-03 07:00 UTC (Friday through Sunday).

What

Adds one Platform entry to docs/release_notes/cloud/readme.md for the Data Worker usage reservation fix.

airbytehq/airbyte-platform-internal

The following pull requests are included in release notes.

PR	Description	Reason
#19236	Makes the Data Worker capacity reservation insert conditional on the job still being non-terminal, and only increments the hourly usage bucket when a reservation is actually created.	User-visible accounting fix: the race left orphaned reservations that permanently inflated an organization's Data Worker usage (shown on the Usage page) and reduced capacity available for new syncs. Confirmed in production.

The following pull requests were merged, but not included in release notes.

PR	Description	Reason
#19231	Adds a root CONTRIBUTING.md and fixes CODEOWNERS.	Internal developer documentation, no user-facing effect.
#19235	Removes remaining Helm chart v1 leftovers (publish script, workflow references).	Deployment tooling for Self-Managed; not a Cloud user-facing change.
#19230	Adds ArtifactHub annotations to the V2 Helm charts.	Helm chart metadata for Self-Managed operators; belongs in Self-Managed release notes if anywhere.
n/a	Three automated chore: update connector assets commits (Aug 1-3).	Automated connector metadata sync, never user-notable.

How

Inserted a new ## August 3, 2026 section directly below the page heading, above all existing entries. No existing content modified.

  • /bump-version - Bumps connector versions, scraping changelog description from the PR title.
    • Bump types: patch (default), minor, major, major_rc, rc, promote.
    • The rc type is a smart default: applies minor_rc if stable, or bumps the RC number if already RC.
    • The promote type strips the RC suffix to finalize a release.
    • Example: /bump-version type=rc or /bump-version type=minor
  • /bump-progressive-rollout-version - Alias for /bump-version type=rc. Bumps with an RC suffix and enables progressive rollout.
• ❇️ AI Testing and Review (internal link: AI-SDLC Docs):
  • /ai-prove-fix - Runs prerelease readiness checks, including testing against customer connections.
  • /ai-canary-prerelease - Rolls out prerelease to 5-10 connections for canary testing.

    • Optional args: connector=<CONNECTOR_NAME> (defaults to the modified connectors in the PR), strategy=fast|slow|default (defaults to fast).
    • Example: /enable-autopilot-rollouts or /enable-autopilot-rollouts connector=source-faker strategy=slow
