+## [0.9.2] — 2026-10-28
+
+Fixes from a code and security review. None of them change how containers are
+monitored or recovered.
+
+### Fixed
+
+- **A bad value saved from Settings can no longer stop Inspector from starting.**
+  The forms now reject invalid times (maintenance start/end), unknown log levels and
+  out-of-range numbers (for example `interval_seconds: 0`, which made the loop spin).
+  If `config.yml` already has such a value, Inspector starts with the default and
+  logs a warning instead of crashing in a restart loop.
+- **The dashboard password can no longer be cleared.** Saving an empty password (or
+  username) is refused, and an empty password never signs anyone in. Before, clearing
+  it left the running dashboard open to anyone.
+- **Passwords with non-ASCII characters (é, ü, £ …) now work.** Before, every login
+  attempt with one crashed.
+- The Events page no longer errors for a moment after a container is removed.
+- The HTTP check hint no longer suggests `302` as an expected status; redirects are
+  followed, so the final page's code is what counts.
+
+### Security
+
+- **Sign-in throttling:** after 5 failed sign-ins (form or Basic Auth) from one address
+  within 5 minutes, that address is refused for the rest of the window.
+- **Changing the dashboard username or password signs out existing sessions.**
+  Expired sessions are cleaned up.
+- Request bodies are limited to 1 MB; an invalid `Content-Length` gets a 400.
+- The Gotify token is sent in the `X-Gotify-Key` header instead of the URL, so it no
+  longer appears in Gotify or reverse-proxy access logs.
+- Portainer token environment variables must be named `PORTAINER_…` (a name already in
+  your `config.yml` keeps working), so Test connection can't be used to send other
+  container secrets to an arbitrary URL.
+- Single quotes are escaped in HTML, and the delete confirmations build their text safely.
+- Two settings saves at the same moment can no longer overwrite each other.
+- `requests` updated to 2.32.5 (CVE-2024-47081).
