+## [1.7.4] — 2026-06-10
+
+### Fixed
+
+- **Share modal kept stale input after creating a link** — clicking "Create" only cleared the label field; scope type, user email, date range, and expiry kept their values, so the next link silently inherited the previous link's scope settings. The form-reset logic from `openShareModal()` is now a shared `_resetShareForm()` helper called after every successful create (the generated link row stays visible for copying).

+
+## [1.7.3] — 2026-06-10
+
+### Fixed
+
+- **App restart no longer hops to a new port** — the in-app update restart (and any quick stop/start) left connections from the previous instance in TIME_WAIT, and the startup port probe did a plain `bind()` that treats TIME_WAIT as occupied — so the restarted app silently came up on 5101 and the browser's reload poll never found it. The probe now sets `SO_REUSEADDR` (matching how Werkzeug actually binds, so an actively listening port is still detected as occupied), and the requested port gets a 10-second grace period before the auto-increment fallback kicks in, covering the brief window where the old process hasn't fully released the socket.
+
+- **Share links now respect a reverse proxy** — `_getShareBaseUrl()` rewrote every copied share link to `http://<LAN-IP>:5100` (via `/api/local_ip`), which would bypass TLS when the scanner sits behind a reverse proxy (Zoraxy, Caddy, nginx, …): a DPO opening the link would silently fall back to plain HTTP. The LAN-IP rewrite now only applies in the case it was built for — browsing the app at `localhost` over HTTP, where `window.location.origin` would produce links unusable from other machines. Any HTTPS or non-localhost origin is used as-is.

 - **`window.VIEWER_MODE`** — injected by Jinja2. `auth.js` adds `viewer-mode` class to `<body>`; all hide rules are CSS (`body.viewer-mode …`) except `delBtn` which is also guarded in JS.
 - **`window.VIEWER_SCOPE`** — injected alongside `VIEWER_MODE`. If `VIEWER_SCOPE.role` is set, `auth.js` pre-sets `#filterRole` and hides the dropdown.
 - **Token onclick attributes** — Copy/Revoke buttons pass the token as a single-quoted JS string literal, never via `JSON.stringify` (which produces double-quoted strings that break `onclick="…"` attributes).
-- **Share link base URL** — `_getShareBaseUrl()` fetches `/api/local_ip` (LAN IP via UDP probe to `8.8.8.8`) so copied links are routable from other machines. Both `createShareLink` and `copyTokenLink` are `async`. Do not revert to `window.location.origin` — that produces `127.0.0.1` links.
+- **Share link base URL** — `_getShareBaseUrl()` uses `window.location.origin` whenever the page is served over HTTPS or from a non-localhost host (a reverse-proxied hostname or LAN IP is already routable, and rewriting it to `http://<LAN-IP>` would bypass the proxy's TLS). Only when browsing at `localhost`/`127.0.0.1` over HTTP does it fetch `/api/local_ip` (LAN IP via UDP probe to `8.8.8.8`) so copied links work from other machines. The result is cached in `_shareBaseUrl` so Copy buttons stay within the click gesture. Both `createShareLink` and `copyTokenLink` are `async`. Do not make it return bare `window.location.origin` unconditionally — that reintroduces unusable `127.0.0.1` links.
 - **Settings Security pane** — Admin PIN and Viewer PIN groups live in `stPaneSecurity`. `switchSettingsTab('security')` triggers both `stLoadPinStatus()` and `stLoadViewerPinStatus()`.
