The Changelog: Software Development, Open Source

Adam and Jerod get into the news, Jerod officially retires from the pod (and Changelog), plus a bonus for our Changelog++ subs!

Burke Holland works on GitHub Copilot by day and codes with his AI agents always. Early January, Burke posted about how Opus 4.5 changed everything. We were all still buzzing from the holiday-season 2x usage bump Claude gave us, and Opus 4.5 felt like a genuine step function in capability. Burke and I get into all the details. Opus 4.5 may have started the fire, but GPT-5.3 Codex is certainly living up to the hype.

Wes McKinney on the mythical agent-month, install Peon Ping to employ a Peon today, Andreas Kling explains why Ladybird is adopting Rust, Cloudflare has a new MCP server that's quite efficient, and Elliot Bonneville thinks the only moat left is money.

Steve Ruiz joins us for a deep-dive on tldraw (a very good free whiteboard) and the business he's built selling SDKs that help others build very good whiteboards (and more) with tldraw's high-performance web canvas.

Along the way, we discuss the excitement/fear we share about keeping our agents busy, how SDK and infra companies are affected differently by agentic software than SaaS companies, how Steve is approaching the coming era of internal tooling, what will happen when we equip LLMs with an infinite canvas, and more.

Peter Steinberger joins OpenAI, ZeroClaw is "claw done right", MimiClaw runs on a $5 chip, Steve Yegge on managing the AI Vampire, and the day the telnet died.
