Agent Delta

Free weekly email

What changed in AI this week, and what to change in your agent.

A free weekly newsletter for people already building AI agents. Five changes that matter, each with what shipped, why you care, and what to do about it.

Written by Juan Munoz. AI engineers, developers and technical founders shipping agents in production.

What it covers

  • Model & API releases

    New models, breaking changes and migration gotchas, from official changelogs.

  • Deprecations with deadlines

    What's going away, when, and which strings to grep for.

  • SDKs, frameworks & MCP

    Agent framework releases, security fixes and protocol changes.

  • Evals & observability

    Tools that help you measure and debug agents in production.

  • A "Do this" for every item

    One concrete action per change. Every item links its official source.

Items are sourced only from official changelogs, release notes and docs.

How an issue is built

Each issue has a TL;DR, five numbered items (each with What shipped, Why you care, Do this, and an official source link), and quick hits.
