 # RustProxy source and documentation maintenance

+Current source version: **0.36.1**. The Cargo package and binary are named `rust-proxy`.

 Before editing, read [README.md](README.md), the relevant [documentation guide](docs/README.md) and the actual code and tests. Historical release experiments are not current specifications. Use the bundled `src/admin/openapi.json` for API routes and payloads; the source implementation is authoritative for runtime behavior.

 Release history focused on **features, settings, default behavior, compatibility and fixes**. Changes to internal code structure and preliminary performance experiments are intentionally omitted. Historical descriptions reflect their respective releases; consult the current documentation for the settings available in the latest release.

+## 0.36.1 — interface icon polish and on-demand live logs
+
+- **SVG icon polish:** HTTP/2 and HTTP/3 tabs now use the same protocol icon; listener HTTP/2/HTTP/3 limit links use the settings cog; **Apply preset** uses a preset/wand icon; the top **Logs** menu receives its missing icon. Compact Overview layout controls keep their native `+ / − / ← / → / ×` glyphs instead of receiving duplicate SVGs, and UI icon sizing is protected from chart SVG rules.
+- **WebSocket tunnels:** **Active tunnels** is now a compact clickable badge without an SVG icon.
+- **Overview metric cards:** removed the redundant **Recent samples / Ostatnie próbki** footer from the lower metric tiles; the footer is shown only when a metric has real detail text to present.
+- **Appearance copy:** removed the experimental/default-state sentence from the SVG icon option help text. The option remains account-scoped and off by default.
+- **On-demand live logs:** the panel status SSE uses `/api/events?...&logs=false`; `/api/logs` refreshes only while the Live Logs window is open or docked and actively following the bounded buffer. Closing, pausing or expanding the history view stops periodic log reads; reopening/resuming triggers an immediate refresh. Existing `/api/events` API consumers remain compatible because the new `logs` query parameter defaults to `true`.
+- **OPNsense certificate deploy:** the source release now includes the previously referenced `rustproxy-acme.conf.example` and `actions_rustproxy_cert.conf`; the integration guide explicitly requires certificate scope plus `allow_deploy` for the deployment credential.
+- **Preference persistence fix:** expanded the per-administrator UI preference document limit from 4 KiB to 64 KiB. Customized Overview layouts can exceed the old limit once widget widths are stored; affected saves previously surfaced as `auth.unavailable` even though authentication was healthy.
+- **Upgrade notes:** the SQLite schema is migrated automatically to expand administrator preference storage; proxy configuration is unchanged.
+
+## 0.36.0 — leaner administration polling
+
+- **Experimental interface icons:** **Settings → Appearance → Interface → Show SVG interface icons** adds semantic inline SVG icons to navigation, action buttons, tabs and dialogs. The account-scoped option is **off by default**, keeps text labels as the accessible source of meaning, follows the current theme via `currentColor`, and can be disabled without changing the original control layout or behavior.
+- **Polling API:** `GET /api/cache`, `GET /api/transform` and `GET /api/traffic` now accept `view=live` for lightweight periodic refreshes. The default response remains the complete backward-compatible payload. Live responses carry the configuration `revision`, and the panel automatically reloads static data when that revision changes.
+- **Panel network load:** Cache and Transform polling no longer retransmit static settings/Vhost configuration on every refresh; Traffic polling omits the static Vhost list. Certificate API credentials are fetched only when the corresponding Settings tab is opened.
+- **Refresh behavior:** configuration writes and operational actions refresh status without also forcing a full `/api/logs` snapshot. Initial load, explicit log refresh and the existing live-log/fallback path retain log coverage.
+- **API contract:** OpenAPI documents the polling views and revision fields; regression tests cover compatibility, invalid views and the panel refresh contract.
+- **Upgrade notes:** no configuration or database changes are required. Existing API clients that do not send `view=live` retain their previous response shapes, with the additive `revision` field on Cache, Transform and Traffic observations.
+
+## 0.35.5 — Overview polish and cache build fix
+
+- **Overview charts:** the cache-results heading now matches the other chart headings and its HIT/MISS/BYPASS legend stays on one line; system uptime is shown in the System load header; the backend count is aligned with Open connections; the redundant Requests per second footer was removed from the PHP requests tile.
+- **PL/EN status labels:** the sidebar healthy-state label is now **SYSTEM OK**, and the application self-check uses the shorter **API** label.
+**Upgrade notes:** no configuration or database changes are required.
+
+## 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.

+For browser polling, `GET /api/cache?view=live`, `GET /api/transform?view=live` and `GET /api/traffic?view=live` omit static response members that do not need to be retransmitted on every interval. Their `revision` identifies the active configuration; when it changes, clients should fetch the corresponding endpoint without `view=live` and refresh their cached static fields. Requests without `view=live` remain the complete compatibility form. Cache live responses contain metrics/dashboard/bans, Transform live responses contain resources/metrics, and Traffic live responses retain current settings/GeoIP/analytics while omitting the static Vhost list. Unknown `view` values are rejected.

 Certificate inspection accepts `{ "cert_file": "filename.pem" }` for a managed file or an absolute external path and returns `{ "cert_file": "...", "covered_hosts": ["example.com"] }`. It applies the existing certificate-file trust and size checks and reads no private key. It makes no configuration or permission changes. This POST requires the signed-in administrator's normal Origin, request-marker and CSRF checks; general RO/RW API tokens and certificate-only credentials cannot call it.

 Enabled tiles are added at the end of the Overview, so the standard block layout does not change.

-The **Remember choice** control next to the history sample count shows a status only when the current choice is temporary (not saved) or briefly after saving.
+The Overview history sample count is saved in the browser immediately when the selection changes; no separate confirmation button is required.
+
+The sidebar application-status indicator runs a lightweight self-check from the live status already used by the dashboard. Green means healthy, amber means attention is needed, and red means a problem was detected; click it to see API, listener, backend and logging details.

 The unlocked Overview layout exposes a single **Save and lock** action (plus Cancel), removing the redundant lock-and-save button.

+### Arranging blocks
+
+After **Unlock layout**, every block shows a compact toolbar: the **⠿** handle, width **− / +**, and **×** to hide it (wider blocks also show **← / →**).
+
+- **Drag:** grab the ⠿ handle (mouse, pen or touch). The block lifts and follows the pointer, and a dashed frame of the same width shows exactly where it will land; neighbouring blocks glide aside instead of jumping. Release to drop, or press **Esc** to return the block to its previous place. Dragging near the top or bottom edge of the window scrolls the page.
+- **Keyboard:** focus the ⠿ handle and use the arrow keys to move the block one position.
+- **Fill gaps:** a saved custom layout keeps blocks in exactly the order you arranged them, so a wide block that does not fit at the end of a row leaves a visible gap instead of other blocks silently moving into it. Use **Fill gaps** to pack blocks into empty space once; nothing is stored until **Save and lock**.
+
 **Dashboard Presets** supports up to **16 named layouts per administrator**. Save, load, rename, overwrite and delete presets; a factory layout can be restored. Presets preserve the dashboard arrangement, not the live traffic values. Interface theme, scale and other display settings are also account-scoped and do not alter proxy routing or rewrite shared configuration.

+### SVG interface icons
+
+Under **Settings → Appearance → Interface**, enable **Show SVG interface icons** to add semantic line icons to the main navigation, action buttons, tabs and dialogs. The preference is stored per administrator as `interface_icons: true|false` in `/api/preferences` and is **off by default** for both new and upgraded accounts.
+
+The icons are inline SVGs bundled with RustProxy; no web font, CDN or external icon library is loaded. They use `currentColor`, so the active theme, danger/primary states and disabled-state colors remain authoritative. Text labels and existing ARIA labels remain the source of accessible meaning; the SVGs are `aria-hidden`. Dynamic controls are reclassified when their state changes, so actions such as sort direction, save/loading, show/hide and refresh keep a matching icon. Turning the option off removes the injected icons and restores the original text-only presentation without restarting the panel.
