+## [0.2.39] - 2026-08-07
+
+### Added
+- **Benchmark, redesigned into the console** (⏱ sidebar entry): two explicit modes. **Smart
+  routing** (default) sends every probe through `cortiq-auto` and judges the ROUTER — task label
+  vs expected (✓/✗), complexity tier, chosen model with per-request cost, task-rule badge —
+  with KPIs for answer quality, classification accuracy, TTFT, tok/s and money spent, plus a
+  "requests went to" per-model distribution. **Individual models** compares pinned models
+  head-to-head. Results render live row-by-row, runs land in a browser-side history (per-run ×
+  and Clear-all), custom tests supported, ⚡ quick subset (7) vs full suite (17).
+- **Hard probes that exercise the high tier**: two route-judged tests (science / ops pools)
+  generated fresh each run — interdisciplinary prompts rate high reliably while fixed wordings
+  decay with the router's novelty signal. Pass = the router said `high` and the request escalated;
+  the tiny token budget keeps them at cents even on the priciest model.
+- **One-paste harness setup** on the API-keys page: Claude Code (native Anthropic `/v1/messages`,
+  now on by default, one-click enable for older configs), Codex, OpenCode, Continue and Cline —
+  each pre-filled with the gateway URL and the freshly created key. The gateway detects harnesses
+  already installed on its machine (✓ on the tab, "already configured for this gateway" status).
+- **Stale-tab detection**: open consoles notice a gateway restart via the meta start marker and
+  show a reload banner instead of silently running an old interface.
+- Log viewer Clear button (`DELETE /admin/api/logs`).
+
+### Changed
+- **High complexity escalates over task rules**: at tier `high` the tier chain leads and the task
+  rule demotes to fallback — a `code → cheap-model` rule no longer pins the hardest prompts to
+  the cheap model. Low/medium keep task-rule-first semantics (documented in docs/ROUTING).
+- **Honest stream costs**: the final cost rides a closing SSE event (`cortiq_cost_usd`) since the
+  initial header is written before generation; money renders with 4 decimals (last two smaller)
+  and grows precision below $0.0001 instead of collapsing to $0.0000.
+- **Oracle-sized timeouts**: router default 800 ms → 15 s (hosted escalations take ~10 s);
+  provider clients gained a 10 s connect timeout (dead upstreams fail over fast) with no overall
+  cap so long generations and streams are never cut.
+- Benchmark fairness: +256-token reasoning headroom (thinking models aren't cut mid-`<think>`),
+  router degradation shown as "⚠ router degraded" and excluded from accuracy, "budget spent on
+  reasoning" instead of a misleading "empty answer", creative-writing budget 96 → 512.
+- New-key dialog simplified to account / rate limit / optional custom value.
+
+### Fixed
+- `cortiq bench` results showed "error" with newer cortiq releases that pretty-print `--json`:
+  the parser now finds the last balanced JSON object anywhere in the output, and tok/s prefers
+  steady decode speed (the old heuristic could report `allocs_per_token` as tok/s).
