Changes and Releases

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

• Jun 11, 2026 AI Agents klaus v0.0.201

  Fixed

  • (deps) Update module github.com/giantswarm/mcp-oauth to v0.3.0 in #329 by @renovate[bot]

  Full Changelog: https://github.com/giantswarm/klaus/compare/v0.0.200...v0.0.201

• Jun 11, 2026 Developer Portal backstage v0.135.3

  Fixed

  • Muster: fix the Workflows page failing with “tool not found” against real muster servers. The muster aggregator only exposes its meta-tools over MCP, so the workflow proxy now invokes the core workflow tools through the call_tool meta-tool and unwraps its result envelope. See ./docs/releases/v0.135.3-changelog.md for more information.

  • (oauth) Brokered RFC 8693 token exchange via tokenExchangeBroker config in #834 by @teemow

  Full Changelog: https://github.com/giantswarm/muster/compare/v0.3.17...v0.4.0

• Jun 11, 2026 Developer Portal backstage v0.135.2

  Fixed

  • AI chat: fix chat requests hanging forever when an MCP server is slow or its responses are dropped by the transport. MCP servers now load in parallel with a per-server timeout (15s default, configurable via aiChat.mcp[].timeoutMs); hanging servers degrade gracefully instead of blocking the chat. Also patch @ai-sdk/mcp to treat SSE events without an explicit event: field as message events per the SSE specification, fixing silently dropped responses from MCP servers behind agentgateway. See ./docs/releases/v0.135.2-changelog.md for more information.
