🔧 [2.0.2] — 2026-07-17

✨ Added

MQTT: 4 new sensor topics — temp_min_today, temp_max_today, hum_min_today, hum_max_today are now published every 30 s and registered via HA auto-discovery
MQTT auto-discovery extended — discovery now registers 9 sensors (previously 5); new entities appear in Home Assistant automatically without any manual configuration

🐛 Fixed

Compiler warning: format specifier mismatch — uint32_t variables in uptime formatting now correctly use (unsigned int) cast; eliminates all -Wformat= warnings on ESP32 toolchain where uint32_t resolves to long unsigned int
Buffer overflow warning: port_str — increased from [8] to [16] bytes in custom_mqtt.h; eliminates -Wformat-truncation= warning for port numbers
Unused function warnings — keep_alive() and disconnect() in custom_mqtt.h marked with __attribute__((unused)); reserved for future use

ℹ️ Notes

Firmware version string updated to 2.0.2 (visible in web interface)
No display or UI changes — behavior identical to v2.0.1
Flash required to apply MQTT changes; after reflash, new min/max entities appear automatically in HA
