## Worth attention

- **64-Day Certificate Lifetimes Coming Feb 2027**
  https://letsencrypt.org/2026/10/07/64-day-certs.html
  Let's Encrypt announced that certificate lifetimes will drop to 64 days starting February 2027. Anything that renews certificates by hand or with a long cron interval will need to be fully automated and monitored before then. Check that every domain you run (including VPS-hosted ones) renews automatically and that failures alert you.
- **2026 Usage Policy update**
  https://www.anthropic.com/news
  Anthropic posted a 2026 Usage Policy update. The item carried no body text and the link is the generic news page, so what changed is unknown. Since your products are built on Claude, read the policy diff directly for anything affecting MCP/agent or contractor-verification use cases.
- **Show HN: Durable Actors – OSS Durable Objects with configurable compute**
  https://github.com/TerseAI/durable-actors
  Terse released Durable Actors, an open-source take on Cloudflare Durable Objects: one named, single-threaded actor with its own SQLite DB, aimed at multiplayer and coordinated agents. It targets lock-in to Cloudflare's stack. Worth a look if you build stateful agent backends, but it is a brand-new project with only the authors' claims behind it.
- **MXC - a sandboxed code execution system**
  https://github.com/microsoft/mxc
  A Microsoft GitHub repo called MXC is described as a sandboxed code execution system. Sandboxed execution is a core building block for running agent-generated code safely. No content was fetched, so scope, licence and maturity need checking before relying on it.
- **ttok 1.0**
  https://simonwillison.net/2026/Oct/9/ttok/
  Simon Willison shipped ttok 1.0, a token-counting CLI whose default tokenizer is now the GPT-5/GPT-6 family rather than GPT-4. He cites a third-party experiment showing GPT-5.5/5.6/6 variants all produce identical token counts on 31 fixtures, though OpenAI has not confirmed GPT-6 uses the same tokenizer. Useful if you estimate prompt costs from the command line.
- **Introducing the Anthropic Cyber Mission**
  https://www.anthropic.com/news
  Anthropic announced an initiative called the Anthropic Cyber Mission. No detail was retrievable, so treat it as a headline to watch for concrete programs or API/policy implications.
