Grafana OnCall's open-source line is in upkeep mode: runtime pins and Helm bumps, no features.
The last four releases of Grafana OnCall's open-source build contain no user-facing changes. Two Helm chart releases in mid-2025 were followed by v1.16.10 and v1.16.11 in early 2026, which pin Python 3.12.11, update urllib3, and adjust the Telegram integration's imports. The project still ships, but only to keep its dependencies current.
SigNoz makes LLM traces readable with a conversation-style Thread view.
SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

The project still ships, but only to keep its dependencies current.
The cadence is slowing: two releases in summer 2025, then a five-month gap, then two patch releases two weeks apart in early 2026. Nothing in these notes points to new alerting, scheduling, or escalation work in the open-source line.
Expect more v1.16.x patches for dependency and runtime hygiene, if any arrive at all; the entries give no sign of a 1.17 or a feature release.

SigNoz is moving into LLM observability from both sides: August's plugin put it inside AI coding agents, and the Thread view now makes it a place to debug AI apps. Underneath, the alerting API keeps migrating on fixed, repeatedly announced dates. Alert channels into incident tools fill out the operational side.
Expect more AI-specific views on top of the Thread view, such as token or cost breakdowns per conversation, and the v1 rules removal to ship on November 11 as announced.
