GitHub Copilot CLI ships v1.0.77-v1.0.78 with sandbox and session workflow improvements
GitHub
Copilot CLI v1.0.77 (Jul 30) added a web-based OAuth login as default for local terminals, Ctrl+G editor-based answer editing, and MDM-enforced sandbox policy; v1.0.78 (Jul 31-Aug 1) sped up resuming long sessions (a 230MB/74k-event transcript loads in under a second at roughly a quarter of the previous peak memory), added a /permissions command, and fixed extension slash-command double-invocation and sessionEnd hook firing for piped runs.
Why it matters
Continues GitHub's push to make Copilot CLI a serious terminal coding agent competitor to Claude Code and Codex CLI, with session-resume performance work directly targeting long-running agent workflows.
Importance: 2/5
Notable incremental update with real session-resume performance and sandbox-policy changes, official source only.
