Latest release — v0.17.0

A minor release after 0.16.4 focused on new coordination and workflow surfaces: bounded Hermes MCP coordination, canonical $design workflow guidance, plugin-mode skill marketplace exposure, stronger UltraQA adversarial contracts, Windows native-hook reliability, tmux ownership safety, startup shell isolation, committed project-memory loading, and Ultragoal task-scoped goal reconciliation.

Added:

Hermes MCP bridge: bounded tools for session/status reads, audited follow-up dispatch, safe artifact reads, log tails, session starts, and coordination reports without exposing tmux scrollback or raw private state.
Canonical design workflow: DESIGN.md and mirrored $design skill guidance now define the design workflow; frontend-ui-ux is deprecated.
Plugin-mode skill discovery: setup registers and verifies the local Codex plugin marketplace/cache and plugin-scoped MCP metadata, including Hermes.

Changed:

$ultraqa is adversarial by contract, requiring hostile scenario modeling, prompt-injection attempts, interrupts/cancel/resume, stale state checks, temporary harnesses when useful, and cleanup evidence.
CLI-first runtime authority guidance is clearer about what the CLI runtime owns versus MCP/default setup paths.

Fixed:

Windows native hook launch preserves stdio and exit status through a PowerShell ProcessStartInfo shim.
Tmux continuations verify mode/session/window ownership before injecting follow-up prompts.
Startup tmux launches avoid shell rc fan-out before Codex starts.
Ultragoal can reconcile completed task-scoped aggregate Codex goals back to the active OMX story with strict evidence gates.
Release-review MCP/Hermes tests isolate inherited runtime env and canonicalize macOS temp roots.

v0.16.4

A post-0.16.3 reliability patch for approved execution handoffs, context-pack metadata visibility, Codex hook feature-flag migration, setup/notify ownership, HUD/runtime state-root visibility, Ralph completion audit evidence, and Ultragoal completion proof requirements.

Added:

Approved context references now carry context-pack refs, private entry metadata, canonical PRD aliases, ready role refs, multiline launch hints, and visible-hint lineage through Ralph, Team, and planning handoffs.
Ralph completion now records and checks audit evidence before accepting done-state claims.

Changed:

Ultragoal completion requires final cleanup/review proof, and the docs/skills make that stop condition explicit.
Skill catalog guidance is tightened around active OMX runtime surfaces.

Fixed:

Codex hook setup now prefers [features].hooks = true when supported, keeps the legacy [features].codex_hooks = true fallback, dedupes stale aliases, and retains hooks after clear resets.
Approved handoffs survive Team scale-up, multiline launch hints, visible hint lineage fallbacks, context-pack parsing edge cases, and stale PostCompact/notify recursion hazards.
HUD, boxed Team state-root precedence, plugin-mode skill discovery, and plugin MCP cleanup stay rooted in runtime authority.

v0.14.4

A patch release that promotes the default frontier lane to gpt-5.5 while keeping the standard/mini and spark lanes pinned to their existing exact models.

Changed:

Frontier defaults now target gpt-5.5 across runtime defaults, Codex agent defaults, and omx explore fallback behavior.
Setup/config guidance and regression coverage now describe the gpt-5.5 default while preserving the existing context-size recommendations.
Generated setup config and executor worker launch defaults now use medium reasoning by default.
Mini and spark lanes remain exact: gpt-5.4-mini and gpt-5.3-codex-spark are unchanged.

Fixed:

Release metadata drift across Node/Cargo metadata, lockfiles, changelog, release body, release notes, and release-readiness collateral.

v0.14.3

A reliability hardening release after 0.14.2 covering omx question/deep-interview return-pane behavior, project-local explore launch context, setup TOML repair safety, HUD window targeting, ultrawork protocol alignment, BusyBox cleanup compatibility, stale Stop/autopilot state handling, supervisor runtime events, Docker-host tmux question rendering, and native Windows psmux worker pane bootstrap hardening.

v0.14.2 and v0.14.1

Patch releases focused on interactive orchestration reliability: safer omx question renderer behavior, shared tmux answer-submit semantics, tighter deep-interview state handling, Korean ulw keyboard drift handling, setup/update refresh resilience, lifecycle contract cleanup, and clearer deep-interview background-question guidance.

v0.14.0

A minor release centered on interactive orchestration changes, including the new omx question blocking-question entrypoint, structured deep-interview question obligations, advisory triage routing, validator-gated autoresearch, explicit runtime run outcomes, clearer specialist routing, and release-proof hardening for the shipped package.

v0.13.x series

A series covering omx adapt foundations, Ralph/runtime authority fixes, hook and HUD reliability, worker identity preservation, security hardening, and detached tmux startup repairs.
