🩹 oh-my-openagent v4.19.1 — Quieter, tougher, and routed through Sol
A stability-first patch. Nothing changes about how you drive omo, but a lot changes about how well it behaves underneath: GPT defaults now route through GPT-5.6 Sol, stray background processes get swept instead of piling up, and a wave of Windows and Codex install fixes lands so the rough edges from v4.19.0 are gone.
🧠 GPT defaults now run on GPT-5.6 Sol
Active GPT defaults — including the Oracle reviewer — now route through GPT-5.6 Sol, with the prompt identity and guardrails aligned to match. The retired gpt-5.5 fallback rungs are purged so nothing silently falls back to an older model, and the builtin Kimi fallbacks are promoted to K3. You get the newer, stronger routing automatically with no config change.
🧹 No more orphaned background processes
omo now runs a family-based process sweep at startup that cleans up stale codegraph and LSP helpers, and every stdio MCP server (LSP, git-bash, codegraph bridge) now carries a parent-liveness watchdog that exits the moment its parent dies. The LSP daemon also reaps older-version daemons on startup. If you ever noticed leftover helper processes lingering after a session, that class of leak is closed.
🔎 CodeGraph 1.4.1 + opt-in shared daemon
The vendored CodeGraph binary is pinned to 1.4.1, with MCP init guidance aligned to its new output shapes. A new opt-in shared codegraph daemon mode (OMO_CODEGRAPH_DAEMON) is available across OpenCode and Codex for teams that want a single long-lived index instead of per-session spawns.
🩺 Sharper LSP diagnostics
Silent language servers that never push diagnostics no longer stall behind a freshness timeout — omo now resolves clean diagnostics for no-pull servers and guards the fallback with a version-current pull cache. The LSP daemon also reports cancelled and timed-out requests accurately instead of mislabeling them.
⚙️ ulw-loop batch efficiency
The ulw-loop gained atomic batch steering (steer --proposals-json), validation-batch review boundaries, and next-goal auto-advance fused into the checkpoint, so multi-goal loops advance with far fewer round trips. ulw-plan now enforces its mandatory opening announcement, and stop-resume writes are contained to the session state dir.
🪟 Windows & Codex install hardening
A broad reliability pass for Windows and Codex users: bun test now exits cleanly on win32 (held-open streams destroyed, isProcessAlive never throws), the codex.cmd shim resolves for doctor spawns, cold-start SessionStart hook timeouts are raised to 15s, duplicate role registration is avoided, npm-install lock drift after local dep rewrites is fixed, and the lazycodex marketplace payload bundles its component CLIs correctly.
🎯 Model routing fixes
antigravity-gemini-3-flash ids are no longer rewritten to an invalid -preview id, and GPT-5.6 (sol/terra/luna) now carry proper 372k PostCompact context budgets so compaction stops applying the 200k fallback.
