What's New in Foundry 1.7.0 — Agent Payments, Realtime Logs, and a console.table

Description

Foundry 1.7.0 just shipped, and there are three things in here worth your afternoon: realtime test logs, a built-in forge lint, and agent-payable RPC. We go hands-on with the first two, and break down what agent payments actually mean for autonomous infrastructure. The buried gem is MPP — Machine Payments Protocol. RPC providers can now answer with HTTP 402, attach a payment challenge, and Foundry signs and retries automatically. No API key. No dashboard signup. Your CI agents can pay for what they use, on demand. The hands-on parts: console.log streams in realtime inside forge test (no more waiting for the run to finish), and forge lint catches gas-wasteful patterns out of the box — we replace two require strings with custom errors and watch the warnings disappear.
