 # Docs changelog

+The documentation has been updated to reflect the general availability of direct organization billing for premium request usage in Copilot Code Review. Organization members without a Copilot plan can now use Copilot Code Review on GitHub.com, with premium request usage billed directly to their organization or enterprise. See [Copilot code review without a Copilot license](https://docs.github.com/en/copilot/concepts/agents/code-review#copilot-code-review-without-a-copilot-license).
