v1.6.0
- MQTT + Home Assistant Discovery: automatic entities and expanded diagnostics.
- Configurable publish interval (10–3600 s, default 60 s) plus immediate publish on key events.
- API hardening: mutating endpoints are now POST-only with X-ESP32MIC-CSRF, plus strict input validation.
- Boot log time fix: correct local offset is applied from the very first log line.
- Web UI is now served as gzip-compressed content from PROGMEM, reducing flash usage after firmware size exceeded 100% capacity.
