GitHub Copilot CLI gains enterprise BYOK; Copilot-authored PRs surface in author search

What's new

• BYOK for Copilot CLI (Jun 17): enterprise customers can plug their own model keys (own OpenAI/Azure keys etc.) into the gh copilot CLI.
• Copilot-authored PRs in author search (Jun 18): PRs opened by the agent are finally surfaced when filtering by author.
• Generated release notes credit Copilot PRs (Jun 18): release notes credit the human who opened the PR via Copilot.
• Individual plan sign-ups reopened (Jun 17).

Why it matters

For enterprise teams BYOK + correct attribution are practical gating items – Copilot is moving into regulated environments (finance, healthcare) where companies want their own model routing and audit trail of who/what the agent wrote.

How to try it

BYOK is configured in the Copilot enterprise admin panel; the new PR attribution works automatically across existing repos.
