copilot-cli-release-app[bot] · ghdev · 2026-09-02
GitHub Copilot CLI released version v1.0.83-2.
Added
- Custom agents can list multiple models in the model field, trying them in order until one is available. model-policy: required ensures model changes stay within that list.
- Added support for claude-fable-5.1.
Improved
- Linux sandboxes now restrict network egress to the configured proxy; proxy mode requires slirp4netns, util-linux 2.35+, iptables, and /dev/net/tun access.
