Developers, gear up—GitHub just turbocharged the Copilot CLI with a fresh batch of updates that make coding feel even more like a superpower. Drawing straight from your feedback on bug reports and feature wishes, the team rolled out enhancements this week to streamline terminals, amp up AI models, and fix those pesky hangs. At the heart of it all, Copilot CLI now handles multiline inputs like a pro, welcomes Anthropic’s slick Haiku 4.5 model, and eases server setups for seamless sessions. If you’re knee-deep in command-line adventures, these tweaks promise fewer frustrations and more flow, turning everyday tasks into efficient rituals. As AI tools evolve, Copilot CLI keeps developers ahead, blending smarts with simplicity in the fast-paced world of GitHub workflows.
Copilot CLI’s Latest Upgrades: From Multiline Mastery to Bug-Busting Stability

GitHub’s Copilot CLI thrives on community input, and this week’s drops tackle real pain points head-on. Multiline input arrives via Shift+Enter in Kitty-protocol terminals, while VS Code users can enable it with a quick /terminal-setup command. Say goodbye to clunky single-line limits—now craft complex queries without breaking a sweat.
The spotlight shines on Anthropic Claude Haiku 4.5, a nimble new model that joins the lineup with poetic precision (even the changelog winks at haiku form). For MCP servers, setup gets intuitive: Ditch comma-separated args for full shell commands, and environment vars now parse literally with ${VARIABLE_NAME} for shell refs. Bug fixes ensure tool calls zip through without fails or freezes, making sessions rock-solid.
Noninteractive workflows level up too, respecting GH_HOST for Enterprise auth and smoothing permissions in -p mode. A –allow-all-paths flag grants broad access effortlessly.
Stability shines brighter with revamped session storage—cleaner, scalable, and primed for future integrations. Models flaunt premium multipliers upfront, Windows PowerShell warnings vanish after upgrades, and debug logs pack stack traces plus API IDs for killer bug reports.
