+
+> Sprint: reasoning model param filtering, local provider 404 fix, Kilo Gateway provider, dependency bumps.
+
+### ✨ New Features
+
+- **feat(api)**: Added **Kilo Gateway** (`api.kilo.ai`) as a new API Key provider (alias `kg`) — 335+ models, 6 free models, 3 auto-routing models (`kilo-auto/frontier`, `kilo-auto/balanced`, `kilo-auto/free`). Passthrough models supported via `/api/gateway/models` endpoint. (PR #408 by @Regis-RCR)
+
+### 🐛 Bug Fixes
+
+- **fix(sse)**: Strip unsupported parameters for reasoning models (o1, o1-mini, o1-pro, o3, o3-mini). Models in the `o1`/`o3` family reject `temperature`, `top_p`, `frequency_penalty`, `presence_penalty`, `logprobs`, `top_logprobs`, and `n` with HTTP 400. Parameters are now stripped at the `chatCore` layer before forwarding. Uses a declarative `unsupportedParams` field per model and a precomputed O(1) Map for lookup. (PR #412 by @Regis-RCR)
+- **fix(sse)**: Local provider 404 now results in a **model-only lockout (5 seconds)** instead of a connection-level lockout (2 minutes). When a local inference backend (Ollama, LM Studio, oMLX) returns 404 for an unknown model, the connection remains active and other models continue working immediately. Also fixes a pre-existing bug where `model` was not passed to `markAccountUnavailable()`. Local providers detected via hostname (`localhost`, `127.0.0.1`, `::1`, extensible via `LOCAL_HOSTNAMES` env var). (PR #410 by @Regis-RCR)
+
+### 📦 Dependencies
+
+- `better-sqlite3` 12.6.2 → 12.8.0
+- `undici` 7.24.2 → 7.24.4
+- `https-proxy-agent` 7 → 8
+- `agent-base` 7 → 8
