+## 0.35.4 — Dashboard status and control cleanup
+
+- **Overview samples:** the history sample selector is right-aligned on desktop and mobile and now saves immediately in the browser; the separate Remember choice button is removed.
+- **Application self-check:** the old runtime/control-plane sidebar block is replaced by a color-coded application status indicator. Clicking it shows checks for the control API, listener restart state, backend readiness and logging pipeline issues.
+- **Dashboard footer:** removed the low-value dropped-log counter; API latency and update availability remain.
+- **Navigation cleanup:** removed the static `RUNTIME / Rust / Tokio / Hyper / Axum / Tower / SQLite` text from the sidebar.
+- **Dashboard layout editing:** blocks are now moved by dragging the ⠿ handle with a live drop placeholder (mouse, pen and touch), smooth movement of neighbouring blocks, edge auto-scroll and **Esc** to cancel; arrow keys on the handle move a block from the keyboard. Custom layouts no longer back-fill gaps automatically, so blocks stay where they were placed; the new **Fill gaps** action packs them on request. The edit toolbar is a single compact row, so the layout keeps its shape while unlocked.
+- **Interface fixes:** the WebSocket tunnels title no longer overlaps its **Active tunnels** button; summary tiles on the Cache, Traffic and Transform pages fill each row instead of leaving empty columns; identifier fields (username, certificate, Docker agent and redirect IDs) no longer trigger an invalid-pattern error in current browsers; several layout-editor tooltips showed raw translation keys.
+- **Cache under turnover:** returning freed memory to the operating system is now rate-limited (at most four times per second, plus the regular maintenance pass) instead of running after every eviction. With a full HOT cache and constant replacement this measured about 2.3× higher throughput with the default system allocator (2,900 → 7,000 req/s, one core) at about 7% higher resident memory.
+- **Cache hot path:** popular objects no longer re-link the LRU list on every hit, HOT/COLD index lookups use the already-uniform cache digest instead of a second SipHash pass, and the request-collapsing bypass marker for uncacheable URLs keeps working when its table is full.
+- **Per-response work:** configured `Server` and cache `Via` values are parsed once per worker instead of on every response, and cache diagnostic headers avoid temporary allocations.
+- **Upgrade notes:** no configuration or database changes are required.

 ## 0.35.3 — Overview layout fixes
 
 - **Standard Overview layout restored:** the quick-health tiles added in 0.35.2 (healthy backends, error share, requests rejected by limits, nearest certificate expiry) are now hidden by default and placed at the end of the Overview, so they no longer shift the standard block layout. Enable them in the layout editor when needed.
