OKD 5.0 Release Notes

Updated for stable release 5.0.0-okd-scos.0

This PR adds comprehensive release notes for OKD 5.0.0-okd-scos.0, the first stable release in the 5.x series.

  • Kubernetes 1.36.3 and CRI-O 1.36.4 platform upgrade
  • Storage features: Volume Group Snapshots (GA), Changed Block Tracking (Tech Preview)
  • DRA Partitionable Devices (GA) for AI/GPU workloads

  • Deprecations and upgrade guidance

Methodology:

Generated using:

  • Release controller changelog comparing 4.22.0-okd-scos.10 → 5.0.0-okd-scos.0
  • Chai bot MCP for feature classification verification (GA vs Tech Preview)
  • Feature gate analysis and cross-referencing
  • Comparison with OCP 5.0 release for context

Release Information:

Changes in this PR:

  1. Initial draft based on ec.9 changelog
  2. Updated baseline from 4.22.9 to 4.22.10 (latest stable patch)
  3. Removed features already present in 4.22.10 (GCP Sovereign Cloud, NUMA fix)
  4. Updated to stable 5.0.0-okd-scos.0 release
  5. Removed EC warnings - production ready

Ready for review and merge.

This is a draft changelog for OKD 5.0 based on 5.0.0-okd-scos.ec.9.

Key highlights:
- Kubernetes 1.36.3 and CRI-O 1.36.4 platform upgrade
- Volume Group Snapshots promoted to GA
- DRA Partitionable Devices now GA for AI/GPU workloads
- HAProxy multi-version selection (2.8 and 3.2)
- Enhanced multi-cloud platform features
- Comprehensive storage, networking, and security updates

This draft should be updated after 5.0.0-okd-scos.0 stable release.
Changes:
- Use 4.22.0-okd-scos.10 as baseline instead of .9
- Remove GCP Sovereign Cloud entry (already in 4.22.10)
- Remove NUMA Resources Operator fix (already in 4.22.10)
- Update release controller links to reflect correct comparison

This ensures release notes only highlight features truly new in 5.0,
not backported features already available in 4.22.10.
Changes:
- Update version from ec.9 to stable scos.0
- Update release date to 2026-09-17 (stable release date)
- Remove EC warning - this is now production-ready
- Update all release controller links to 5-scos-stable stream
- Update upgrade path section to reflect TRT acceptance
- Rename file to 09-17 to match stable release date

5.0.0-okd-scos.0 was manually accepted by TRT on 2026-09-17.
