GitHub Copilot can now turn Slack or Teams threads into collaborative cloud-agent sessions. Teammates can add context and steer the work in public, while repository permissions, agent budgets and optional extra PR approvals remain the main control boundaries.
GitHub Copilot for JetBrains now honors enterprise-managed settings for MCP allowlists, plugin marketplaces, OpenTelemetry routing and bypass/autopilot restrictions, giving security and platform teams enforceable controls across another major IDE family.
GitHub Spark stops being available to existing users on August 31, 2026. Deployed apps are meant to keep running, but owners should export code to a repository now; Spark apps using `llm()` need a separate inference provider because the underlying GitHub Models service retired July 30.
Agent Plugins 1.0 now has documented support across VS Code, Cursor, GitHub Copilot, ChatGPT/Codex, Kiro and several open-source agents. That makes the format materially more useful for cross-client distribution, but portable components remain limited to Agent Skills and MCP servers while permissions, hooks, commands and host UX stay client-specific.
GitHub Issues now gives agent automations confidence levels, rationales and optional approvals, letting teams automate routine triage while holding uncertain changes for review.
