 # Changelog
 
+## v2.2.3 - 2026-05-27
+
+### Features
+
+- **Usage reset radar.** New `/subscriptions` page consolidates the Codex Reset Radar summary, recent RSS events, and a reset-time hook. When a window-close signal is detected the backend clears stale cooldown/usage caches and re-tests every account so the pool reflects the new reset boundary immediately.
+- **Streaming batch operations in admin.** Account batch refresh/test/enable/disable/lock/reset now stream per-account progress events (`success/banned/rate_limited/failed`) to the admin UI instead of waiting for the full operation to complete.
+- **Compact usage number setting.** Added a system setting to render token counts with K/M units in the usage table for easier reading at scale.
+- **Card view for account management.** Desktop accounts page gains a table/card view toggle (up to 5 cards per row on `xl` screens). Choice is persisted in `localStorage`.
+- **Status badge error tooltip.** Hovering an `unauthorized` or `error` status badge now surfaces the full upstream error message in a popover, matching the usage log status code tooltip style.
+- **Anthropic `speed: fast` forwarding (#170).** Anthropic-style `speed: fast` requests now map to the Codex priority tier upstream so fast clients get fast tokens end-to-end.
+
+### Fixes
+
+- **Version popover always clickable.** The sidebar version badge now opens the popover even when the GitHub latest-version lookup is still pending or blocked; a "checking…" hint is shown until the remote tag arrives.
+- **First-token timeout and scheduler races.** Hardened the proxy path so first-token timeouts and concurrent scheduler races no longer collapse into a spurious "no available account" 503.
+- **`/responses` WebSocket ingress.** WebSocket clients hitting `ws://host/v1/responses` are now accepted; the prior 404/101 misclassification has been fixed. Setting `CODEX_UPSTREAM_TRANSPORT=ws` no longer reports the connect handshake as an unknown error.
+- **Anthropic content preservation + deactivated probe flagging.** Anthropic-shaped responses keep their original content blocks; deactivated accounts are clearly flagged in probe state instead of silently appearing healthy.
+- **Wham window classification.** Usage window classification now uses `limit_window_seconds` rather than field position, so free-tier accounts no longer have a 7d window misclassified as 5h.
