+## [3.2.6] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **API Key Reveal (#740)** — Added a scoped API key copy flow in the Api Manager, protected by the `ALLOW_API_KEY_REVEAL` environment variable.
+- **Sidebar Visibility Controls (#739)** — Admins can now hide any sidebar navigation link via the Appearance settings to reduce visual clutter.
+- **Strict Combo Testing (#735)** — Hardened the combo health check endpoint to require live text responses from models instead of just soft reachability signals.
+- **Streamed Detailed Logs (#734)** — Switched detailed request logging for SSE streams to reconstruct the final payload, saving immense amounts of SQLite database size and significantly cleaning up the UI.
+
+### 🐛 Bug Fixes
+
+- **OpenCode Go MiniMax Auth (#733)** — Corrected the authentication header logic for `minimax` models on OpenCode Go to use `x-api-key` instead of standard bearer tokens across the `/messages` protocol.
+
+---
+
+## [3.2.5] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Void Linux Deployment Support (#732)** — Integrated `xbps-src` packaging template and instructions to natively compile and install OmniRoute with `better-sqlite3` bindings via cross-compilation target.
+
+## [3.2.4] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Qoder AI Migration (#660)** — Completely migrated the legacy `iFlow` core provider onto `Qoder AI` maintaining stable API routing capabilities.
+
+### 🐛 Bug Fixes
+
+- **Gemini Tools HTTP 400 Payload Invalid Argument (#731)** — Prevented `thoughtSignature` array injections inside standard Gemini `functionCall` sequences blocking agentic routing flows.
+
+---
+
+## [3.2.3] — 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Provider Limits Quota UI (#728)** — Normalized quota limit logic and data labeling inside the Limits interface.
+
+### 🐛 Bug Fixes
+
+- **Core Routing Schemas & Leaks** — Expanded `comboStrategySchema` to natively support `fill-first` and `p2c` strategies to unblock complex combo editing natively.
+- **Thinking Tags Extraction (CLI)** — Restructured CLI token responses sanitizer RegEx capturing model reasoning structures inside streams avoiding broken `<thinking>` extractions breaking response text output format.
+- **Strict Format Enforcements** — Hardened pipeline sanitization execution making it universally apply to translation mode targets.
