GitHub: Copilot Code Review Covers Bot PRs, Drops Size Cap

GitHub Copilot code review got three upgrades in one changelog entry.

What changed: (1) Pull requests authored by bots — including Copilot cloud agent — now get a full agentic review instead of the limited fallback, and with the "allow members without a Copilot license" policy enabled, that usage bills to your organization. (2) The old 300-file or 20,000-line size limit on reviewable pull requests no longer applies. (3) You can now tag a reason — "Addressed," "Won't fix," or "Incorrect" — when resolving a Copilot review comment, via a dropdown next to the Resolve conversation button.

Why a builder cares: the size-cap removal is the headline — large refactors and generated code previously escaped Copilot review entirely. And bot-authored PRs getting real reviews closes the gap for agent-driven workflows: code your agents wrote now gets the same pass as code your humans wrote.
