What is Caddy?

Caddy 2.11's betas add ECH key rotation and a release process without its founder.

Caddy's tracked entries are the two 2.11 betas from December 2025 and January 2026. Beta 1 was the first release cut by the maintainer team's automated process without the original author, and brought time-based log rolling, argon2id basic auth and named socket activation. Beta 2 added ECH key rotation, multiple intermediates in PKI signing chains and a fix for the ZeroSSL issuer.

What is SigNoz?

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.

Caddy 2.11's betas add ECH key rotation and a release process without its founder.

◆ Current state

Caddy's tracked entries are the two 2.11 betas from December 2025 and January 2026. Beta 1 was the first release cut by the maintainer team's automated process without the original author, and brought time-based log rolling, argon2id basic auth and named socket activation. Beta 2 added ECH key rotation, multiple intermediates in PKI signing chains and a fix for the ZeroSSL issuer.

◆ Where it's heading

Caddy is investing in privacy-preserving TLS through Encrypted ClientHello, and in project continuity through a team-run release pipeline. The rest of the betas are edge-case fixes, consistent with a mature server polishing details.

◆ Prediction

The beta notes point to a 2.11 stable release; no newer entries are tracked, so its timing isn't visible here.

SigNoz makes LLM traces readable with a conversation-style Thread view.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
