GitHub Copilot CLI v1.0.79 Adds Kimi-K3 Support and Reworks Sandbox Auth Settings
GitHub (Microsoft)
GitHub Copilot CLI v1.0.79 adds support for the kimi-k3 model, switches large monorepos to trigram-indexed tgrep instead of ripgrep, reworks sandbox settings by moving git/gh auth under a new sandbox.auth.* namespace with no migration path, and renames allowDevToolCaches to allowDevToolAccess as a breaking change.
Why it matters
The breaking sandbox-setting renames mean existing managed/MDM policies silently revert to defaults unless updated, which can quietly widen tool access for teams that don't catch the changelog.
Importance: 2/5
