+> Codex account quota policy with auto-rotation, fast tier toggle, gpt-5.4 model, and analytics label fix.
+
+### ✨ New Features (PRs #366, #367, #368)
+
+- **Codex Quota Policy (PR #366)**: Per-account 5h/weekly quota window toggles in Provider dashboard. Accounts are automatically skipped when enabled windows reach 90% threshold and re-admitted after `resetAt`. Includes `quotaCache.ts` with side-effect free status getter.
+- **Codex Fast Tier Toggle (PR #367)**: Dashboard → Settings → Codex Service Tier. Default-off toggle injects `service_tier: "flex"` only for Codex requests, reducing cost ~80%. Full stack: UI tab + API endpoint + executor + translator + startup restore.
+- **gpt-5.4 Model (PR #368)**: Adds `cx/gpt-5.4` and `codex/gpt-5.4` to the Codex model registry. Regression test included.
+
+### 🐛 Bug Fixes
+
+- **fix #356**: Analytics charts (Top Provider, By Account, Provider Breakdown) now display human-readable provider names/labels instead of raw internal IDs for OpenAI-compatible providers.
 
 > Major release: strict-random routing strategy, API key access controls, connection groups, external pricing sync, and critical bug fixes for thinking models, combo testing, and tool name validation.
