Agent Plugins 1.0 went GA: build once, run across VS Code, Copilot CLI, Copilot SDK, and the Copilot app. Kimi K3 and MAI-Code-1.1-Flash rolled out to paid plans. Copilot CLI gained a /tasks subagent view, --plan plus --mode autopilot headless combos, and /rewind. JetBrains added cross-session memory and Ollama as a BYOK provider.
