In the October 5 weekly release, Claude Haiku 5.5 is available to Copilot Pro, Pro+, Max, Business, and Enterprise users. The update also includes broader controls and workflow improvements intended to make Copilot easier to use across accounts and environments.
GENERAL AVAILABILITY OF LOCAL SANDBOXING ACROSS COPILOT COMPONENTS
Local sandboxing now has general availability for limiting how agents access files, networks, and credentials. The capability is supported across Copilot CLI, the Copilot app, and VS Code sessions using Agent Host. It is included with Copilot at no extra cost and comes with guidance to learn more about sandboxing. TechStaged has also covered Claude Haiku 5.5 becomes generally available in GitHub Copilot, aimed at fast subagent and editing tasks.
SEPARATING COPILOT LICENSES FROM REPOSITORY ACCESS IN THE COPILOT APP
The Copilot app now supports using separate GitHub accounts for a Copilot license and repositories. This enables scenarios such as using an enterprise-provided Copilot license while accessing repositories through a different account.
LOCAL MODEL DISCOVERY AND SELECTION IN COPILOT CLI
GitHub Copilot CLI adds a streamlined way to choose a local model without disrupting workflow. Users can run /model to discover models from a running local Ollama instance alongside their configured models and cloud models provided by Copilot.
USER INTERFACE IMPROVEMENTS FOR AGENT MANAGEMENT
The Agents window now allows viewing sessions side by side in a grid, enabling easier comparison of results or monitoring multiple tasks simultaneously.
DISK-SPACE MANAGEMENT FOR SESSION WORKTREES
An “Open worktree cleanup” feature helps users free disk space by showing how much space inactive session worktrees use and allowing selection of which to remove.
WHY THESE UPDATES MATTER
The changes are designed to make Copilot easier to use across accounts and environments, with more granular control over what agents can access and how work is managed.
