This week's Weekly GitHub Copilot Roundup is about Copilot growing up operationally: more models (GPT-6.1 Sol and Claude Sonnet 5.5), clearer routing with HydraFusion patterns, and more reasons to treat model choice as a governed dependency. Agents kept expanding beyond the IDE with dynamic workflows, scheduled automations, and a new "computer use" preview that brings desktop apps into scope (and into security reviews). Code review automation moved forward with API triggers and a new default effort level, while MCP-based extensibility matured with hosted skills, shared canvases, and managed automation patterns that emphasize evidence, auditability, and controlled execution.

John Savill recaps major Microsoft AI announcements from September 2026, focusing on Azure AI Foundry updates (models, routing, agent features, and controls), Copilot platform changes, and developer-facing items like GitHub Copilot and VS Code agent workflows, plus data/AI additions such as Azure SQL vector capabilities.
