+## [0.2.43] - 2026-08-08
+
+### Added
+- **API keys actually gate the gateway.** Configured `[[api_keys]]` now enforce auth on
+  `/v1`, `/route` and `/mcp` (Bearer or `x-api-key`), attribute every request to the key's
+  account in stats, apply per-key rate limits (`rate_per_min` → 429 with `Retry-After`) and
+  per-key monthly budgets (`monthly_budget_usd` → 429 `insufficient_quota`). No keys
+  configured = open mode, as before.
+- **Auto-detected tool support for managed local servers**: `cortiq serve` ≥ 0.5.63
+  advertises the loaded model's capabilities in `/healthz`; the gateway reads the handshake
+  when the server becomes healthy, so a local model whose chat template can drive tool
+  calling serves agent (tools) traffic with zero manual configuration. Manual override:
+  `caps = ["tools"]` on the `[[cmf.servers]]` entry (also the fallback for older serves).
+- **OpenRouter balance on the dashboard** (when an OpenRouter key is configured): the
+  remaining credit is a KPI card, red under $5.
+- **Harness snippets for every OS** on the API-keys page: Linux/macOS and Windows variants
+  per harness, an install command chip when the harness is missing, and a paste-your-key
+  field that substitutes the real key into every snippet.
+- Deploy guide (`docs/DEPLOY.md`, Russian mirror): systemd/launchd/Windows service, nginx and
+  Caddy TLS fronting, security checklist, backup list.
+
+### Fixed
+- Capability filtering widens the tier chain instead of killing the request: when an AUTO
+  route's chain has no model with the required capabilities (tools), the gateway escalates
+  through medium→high chains and then the rest of the pool instead of returning
+  "No healthy model available". Explicit pins still fail loudly.
+- Semantic-cache threshold no longer renders as `0.9200000166893005` (f32→f64), the cache
+  settings card shows live entries/hits/saved-$ and warns when no embedding model exists.
+- Key-page snippets survive being pasted into a real interactive zsh (no `#` comment lines,
+  no history-expansion `!`), and the install chips are readable in the light theme.
+- Stats log growth is bounded: `[stats] max_file_mb` (default 16) folds old JSONL records
+  into the sidecar totals file — per-account all-time and month spend survive compaction
+  and restarts.
+
+### Breaking
+- If your config already lists `[[api_keys]]` but your clients never send keys, requests
+  will now be rejected with 401 — either remove the keys from the config or start sending
+  `Authorization: Bearer <key>`.
