This directory documents known bugs, regressions, and workarounds for specific OpenStack releases. Check the file for your target release before deploying or upgrading.

When to Read This

  • When investigating an unexpected behavior that appeared after an upgrade
  • When a deployment step fails in a way that is not covered by standard documentation

**Affected versions:** Release range where the bug is present (e.g., "2025.1.0 through 2025.1.2").

**Status:** One of:

  - Fixed in <version> — patch released; upgrade to resolve
  - Upstream fix pending — patch proposed, not yet merged
  - Won't fix — accepted limitation
