## v1.12.5 — host-neutral harness release gates (2026-05-25)

Focused release-prep patch after the host-neutral MCP browser harness SSOT.
This release integrates startup-tab reuse, pilot memory foundations, and
benchmark release-gate hardening while keeping full competitive benchmark
headline claims gated behind live or recorded-real evidence.

See [`docs/releases/v1.12.5.md`](docs/releases/v1.12.5.md) for the full
release notes.

## v1.12.4 — API-key-only benchmark readiness gate (2026-05-17)

Focused benchmark release-safety patch. This release adds an explicit
API-key-only readiness gate, removes closed #1305 from the open benchmark
audit, codifies the remaining non-key benchmark implementation PR ladder, and
keeps benchmark reporting fail-closed until live or recorded-real rows are
actually headline eligible.

See [`docs/releases/v1.12.4.md`](docs/releases/v1.12.4.md) for the full
release notes.

## v1.12.3 — live benchmark execution and publication gates (2026-05-17)

Focused live-benchmark hardening patch. This release adds injectable LLM/tool
use loop seams, native competitor task-loop surfaces, live Chrome/CDP throughput
execution support, recorded-real corpus validation, and stricter headline report
gates so mock/scaffold rows cannot be published as competitive wins.

See [`docs/releases/v1.12.3.md`](docs/releases/v1.12.3.md) for the full
release notes.

## v1.12.2 — benchmark measurement readiness (2026-05-15)

Focused benchmark-readiness patch for the Competitive Benchmark Suite. This
release expands the suite from the v1.12.1 foundation into a fuller measurement
envelope: Playwright MCP, Crawlee, and Browser Use adapters; a 5×10
token-efficiency corpus; WebVoyager task expansion from 18 to 61 tasks; speed,
throughput, reliability, auth, and DX runners; cross-platform bridge smoke
coverage; unified benchmark report generation; and an Epic #1254 close gate
that distinguishes measured evidence from mock-only or queued live cells.

See [`docs/releases/v1.12.2.md`](docs/releases/v1.12.2.md) for the full
release notes.

## v1.12.1 — competitive benchmark suite (2026-05-15)

Focused follow-up to v1.12.0: merges the Competitive Benchmark Suite
(Epic #1254) under `tests/benchmark/` — harness foundation, six scoring
axes, Playwright/Puppeteer competitor adapters, local fixtures, and a
cross-platform benchmark CI workflow. Also adds task-scoped browser lanes
(`oc_lane_*`) and opt-in codegen replay artifacts (`oc_skill_export`).
Default `tools/list` now returns 115 entries (was 110). All changes are
additive or test-only; no new mandatory runtime deps.

See [`docs/releases/v1.12.1.md`](docs/releases/v1.12.1.md) for the full
release notes.

## v1.12.0 — task harness, recovery runtime, CLI MCP driver (2026-05-14)

Largest feature release in the v1.x line: 105 PRs, ~30 new MCP tools, a
goal-level task harness, a deterministic recovery/reflection runtime, a
CLI that drives the MCP surface directly (`oc run` / `oc playbook` /
`oc doctor` / `oc vault`), Streamable HTTP daemon mode, and 2 new MCP
resources. No source files removed; no new mandatory runtime deps.

See [`docs/releases/v1.12.0.md`](docs/releases/v1.12.0.md) for the full
release notes, including the six observable breaking changes and their
migration paths.

## v1.11.x

### Transport policy

A formal transport lifecycle policy has been established in
[`docs/transport-lifecycle.md`](docs/transport-lifecycle.md). The document
covers:

- The three supported transport modes (`stdio`, `http`, `both`) with stability
  status and recommended use cases.
- Stability commitments: message-shape compatibility, guaranteed notification
  types, and what minor versions are permitted to change.
- Deprecation policy: minimum 3 minor versions **or** 6 months overlap between
  announcement and removal, whichever is longer.
- Boot-time deprecation warning contract (implementation deferred to a follow-up
  code PR; no warning is emitted yet).
- Migration recipes: stdio → HTTP, and HTTP → Streamable HTTP (when #839 lands).

**No transport is currently deprecated.** All three transport modes remain
stable with no sunset date. This section will be updated when a transport is
first marked deprecated.

## v1.11.0 — portability-harness contract (2026-05-12)

See [`docs/releases/v1.11.0.md`](docs/releases/v1.11.0.md) for the full release
notes.
