GitHub Copilot moved deeper into shared workspaces with public previews for Slack and Microsoft Teams. The important shift is not just chat integration:
@GitHubcan now plan changes, investigate issues, create PRs, and work asynchronously in a secure cloud sandbox, then hand off back to the terminal, app, or IDE.

Agent Plugins 1.0 is the clearest Copilot platform standardization move this pass. GitHub says you can build a plugin once and use it across VS Code, Copilot CLI, the Copilot app, and the SDK, with skills and MCP servers bundled into one portable package.

Microsoft published Work IQ Developer Tools preview for Microsoft 365 Copilot extensibility. The pitch is strong: go from an empty folder to a published, monitored plugin or declarative agent in one flow, with the tooling explicitly designed so Copilot can drive the lifecycle.

Azure Cosmos DB got a practical agentic-era tooling update for developers. The useful bits are native Copilot tools in the VS Code extension, schema-grounded natural-language query generation, optional MCP via Cosmos DB Shell, and local/CI validation with the Emulator.

Satya Nadella signaled that Microsoft is already routing first-party models into GitHub Copilot, Excel, and Outlook, and that the same approach is expanding to Copilot Chat and PowerPoint. Microsoft also said Microsoft 365 Copilot has passed 30 million paid seats, which makes the model-routing strategy look like a real commercial bet rather than a side experiment.

Microsoft Agent Lightning v1.0 is a notable agent-infrastructure repo update rather than a runtime agent product. The repo frames itself as a 3,500-line RL trainer for agents with real harnesses, native Kubernetes support, and a coding-agent example that improved SWE-bench Verified from 41.8% to 56.4%.
