OpenCode 2.0 Runs One Background Service for Every Client and Ships Code Mode, Background Subagents, and an Embeddable SDK
OpenCode 2.0 makes the client/server model the default: one background service shared by the TUI, web and desktop, Code Mode scripts for MCP tools, background subagents, 80-plus plugins and an embeddable SDK the launch note calls still in development, plus the opt-in upgrade path from 1.19.0.
