Changes and Releases

Updates on Giant Swarm workload cluster releases, apps, UI improvements and documentation changes.

• Apr 27, 2026 Developer Portal backstage v0.124.3

  Added

  • Allow overriding the AI chat context window size via aiChat.contextWindow in app-config.

  Changed

  • Improve markdown table rendering in AI chat: tables are now horizontally scrollable with better cell spacing.

  Fixed

  • Cache-bust custom branding logo URLs so replaced logos appear immediately instead of being served stale from the browser cache. See ./docs/releases/v0.124.3-changelog.md for more information.
• Apr 27, 2026 Developer Portal backstage v0.124.2

  Changed

  • Decouple custom branding from the gs-backend plugin so branding assets are served by a dedicated backend plugin and work without gs: config. See ./docs/releases/v0.124.2-changelog.md for more information.
