backstage release v0.129.3

Sun, 10 May 2026 22:14:10 +0000

Fixed

Stabilise the AI chat transport across React renders. useChatSetup constructed a fresh AssistantChatTransport on every render and handed it to useChatRuntime; when its identity changed mid-stream (e.g. as a side effect of a state update triggered by streamed reasoning-delta / tool-input-delta events), the runtime tore down the in-flight chat fetch with TypeError: network error. Envoy logged the symptom as response_flags: DC (downstream remote disconnect) against a healthy Backstage upstream while the SSE stream summary was sawFinish=false, last event tool-input-delta, surfacing in the UI as a “Network error” banner even though no real network outage occurred. The transport is now memoised on the resolved API URL and the stable getHeaders / debugFetch callbacks, so a single transport lives for the component’s lifetime.
AI chat instrumentation: observe the caller’s AbortSignal and log abort events with the reason inline (ABORT signaled by client at <ms> -- reason: <name>: <message>). Stream-outcome lines now annotate aborted streams with [client-aborted at Nms reason="..."] so a “Network error” banner can be classified as a deliberate client cancel (transport rebuild, unmount, manual stop) versus a real proxy / network failure (no abort signal fired, raw stream error). Read errors that fired after the caller aborted are now logged as console.warn (“cancelled by client AbortSignal”) rather than console.error (“STREAM READ FAILED”), reserving the latter for the genuine pre-finish, non-aborted failure mode.

See ./docs/releases/v0.129.3-changelog.md for more information.

backstage release v0.129.2

Sun, 10 May 2026 14:47:23 +0000

Fixed

AI chat instrumentation: render the SSE stream summary inline in the log message (bytes=... events=... sawFinish=... lastEventType=...) instead of attaching it as a trailing object argument, so it stays readable in browser-console consumers that flatten the args array (devtools-snapshotters, log shippers, the Cursor IDE browser, etc.) rather than collapsing to “[object Object]”. Also classify a stream read error that arrives after a finish event was already parsed as a post-completion teardown (console.warn, message already committed) instead of a network failure (console.error); this matches the actual semantics of the AI SDK aborting the underlying fetch once it has finished consuming the stream. See ./docs/releases/v0.129.2-changelog.md for more information.

backstage release v0.129.1

Sun, 10 May 2026 13:36:28 +0000

Fixed

AI chat: always log network-level diagnostics (request URL, response status / headers, fetch errors, SSE stream lifecycle including premature termination) to the browser console so a “Network error” banner can be triaged from a user report without requiring the ai-chat-verbose-debugging feature flag. Verbose payload-level logging (messages, system prompt, tool schemas, per-event SSE detail) remains gated on the feature flag in non-production builds. See ./docs/releases/v0.129.1-changelog.md for more information.

backstage release v0.129.0

Sun, 10 May 2026 08:53:26 +0000

Added

Make AI chat sampling parameters configurable per installation. The plugin previously called streamText() without temperature, topP, topK, seed, minP, or maxOutputTokens, so the server’s defaults applied – which for vLLM means temperature=1.0, top_p=1.0, top_k=-1, seed=null. That is far too loose for a tool-using agent backed by a reasoning model and was the dominant cause of token-cost variance in production agent loops (same prompt, fresh chat, observed total-token spread of 22k / 607k / 22k across three runs against the same Qwen3 endpoint). Config now accepts an aiChat.sampling block with temperature, topP, topK, minP, seed, and maxOutputTokens; all fields are optional and default behaviour with no sampling: block is unchanged. temperature, topP, topK, seed, and maxOutputTokens are forwarded through the AI SDK to every provider that supports them. minP is spliced into the request body via the OpenAI-compatible provider’s transformRequestBody hook, since vLLM accepts it as a top-level field but it is not part of the AI SDK call settings. The ai-chat-backend README documents recommended values per model family (Qwen3 thinking/non-thinking, Qwen3-Coder, GPT-4 / GPT-4o, Anthropic Claude). See ./docs/releases/v0.129.0-changelog.md for more information.

backstage release v0.128.1

Sat, 09 May 2026 10:54:33 +0000

Fixed

Fix AI chat backend crash on every chat send. The tools field in the request body is optional, so it arrives as undefined whenever the frontend does not register any client-side tools. The previous implementation called Object.entries(tools) unconditionally, which threw TypeError: Cannot convert undefined or null to object, returning a 500 from POST /api/ai-chat/chat on every request. The browser surfaced this as “network error” and the LLM never reached the tool-merge step, so MCP-provided tools (muster, prometheus, kubernetes, …), skill tools, getDate, and the context-usage tool were also unreachable from chat. frontendTools now accepts null/undefined and treats them as an empty registry.
Rebuild MCP clients when the underlying transport closes. The AI chat backend caches one MCPClient per server for 30 minutes, but the cache was holding on to clients whose StreamableHTTP transport had already been torn down by muster (idle timeout, server reset, …). Tool calls then failed with MCPClientError: Attempted to send a request from a closed client until the TTL expired, surfacing in the browser as a “network error” banner. The cache now chains into the transport’s onclose callback and evicts the entry as soon as the connection drops, so the next request rebuilds the client cleanly. Tool execution also detects the same SDK error eagerly and marks the entry dead so a single failure – not a 30-minute window – triggers reconnection. See ./docs/releases/v0.128.1-changelog.md for more information.

loki-app release v0.45.0

Thu, 07 May 2026 07:09:48 +0000

Changed

Upgrade upstream loki helm chart from v11 (11.6.4) to v13 (13.5.0). Loki app version unchanged at 3.7.1.
Pin loki.deploymentMode to SimpleScalable in values.yaml. Upstream v13 changed the default to Monolithic; this preserves the existing backend/read/write topology.
Move gateway route configuration from loki.gateway.route to top-level gatewayRoute. Upstream v13 redefined gateway.route as a strict-schema map of named routes that rejected our flat structure. Consumers overriding loki.gateway.route.* must rename to gatewayRoute.*.
- Note: It’s better if you use the upstream loki.gateway.route. The gatewayRoute section is here for compatibility, and keeping a few extra features we had added.

Notable upstream changes

New default livenessProbe on every loki pod (/loki/api/v1/status/buildinfo, 30s period, 10× failure threshold ≈ 5 min before kill).
Memberlist hardening: defaults add abort_if_cluster_join_fails, IPv6-friendly advertise_addr: ${HASH_RING_INSTANCE_ADDR} (auto-injected from status.podIP), join retry/backoff. Backend/read/write pods now run with -config.expand-env=true.
Server tuning defaults added (graceful_shutdown_timeout: 5s, gRPC keepalive, grpc_server_max_concurrent_streams: 1000, 100 MiB gRPC msg size, http_server_idle_timeout: 30s).
k8s-sidecar bumped 2.6.0 → 2.7.1; gains /healthz liveness/readiness probes on new http-sidecar port (8080).
Gateway nginx image bumped 1.29-alpine → 1.30-alpine.

external-dns-app release v3.5.0

Tue, 05 May 2026 16:56:23 +0000

Changed

Update VPA updatePolicy.updateMode from deprecated Auto to Recreate.
Upgrade external-dns to v0.21.0.
Sync to upstream helm chart 1.21.1.
- Add namespaceOverride value to support deploying external-dns into a different namespace than the Helm release (useful for subchart usage).
- Add enableGatewayListenerSets value to opt into Gateway API ListenerSet resource support.
- Add sourceNamespace value (used with namespaced=true) to watch resources in a namespace different from the deployment namespace.
- Avoid creating cluster-scoped namespace RBAC when gatewayNamespace is set, reducing required permissions.
- Fix extraArgs map handling: boolean values now render as --flag / --no-flag and string values are properly quoted.
Use external-dns.namespace in VPA and NetworkPolicy resources.
