opencode v2.3.0 ships background subagents by default

github-actions[bot] · ghdev · 2026-11-13

opencode released v2.3.0 with notable workflow changes:

Background subagents by default: subagents now return their session ID immediately, keep running in the background, and report back to the parent when idle — multiple subagents can run concurrently without blocking the main session.
Quieter transcripts: the TUI collapses each run of tool calls and thoughts into one collapsible activity row; set Verbosity to medium/high (or session.verbosity) to see every step again.
Jump to an earlier prompt: desktop app adds Jump to message (Cmd/Ctrl+Alt+G) to search prompts across the session and jump directly to one.
Other improvements: experimental MCP events support behind the mcpevents flag, backgrounding shell commands on timeout (shelltimeoutbackground flag), shell commands surviving server handoffs, and Windows local commands now running through the process daemon.
