+# Project Aura v1.1.1
+
+Release date: 2026-03-16
+
+## Status
+- This is the latest stable firmware before the public Project Aura release on MakerWorld.
+- A lot has changed since `v1.1.0`; the points below summarize the main user-facing and stability improvements.
+
+## Highlights
+- Web delivery has been reworked with embedded versioned assets for the Dashboard, Fan Control page, and Theme page, plus multiple transfer hardening improvements for difficult Wi-Fi environments.
+- MQTT and Wi-Fi recovery behavior was refined for congested 2.4 GHz networks, with safer reconnect timing and reduced connection pressure.
+- RTC support was expanded with DS3231 and PCF8523 autodetection, shared-address fault handling, clearer status visibility, and a manual RTC override mode.
+- Sensor and peripheral robustness was improved for SEN66, SFA30, BMP58x/BMP388/BMP390, optional CO sensing, and DAC availability/fault reporting.
+- Fan Control received multiple updates including HCHO support in auto mode, restored armed-auto behavior after reboot, synchronized timer presets, improved QR and direct-link access, and better web/UI consistency.
+- The UI and web diagnostics flow were improved with a live system log screen, clearer OTA/update states, localized overlays, and more polished AP/STA dashboard behavior.
+- Stability work also reduced steady-state memory drift and muted noisy low-level LCD panel I2C logs.
+
+## Notes
+- OTA update keeps user settings.
+- Recommended GitHub release asset:
+  - `project_aura_1.1.1_ota_firmware.bin`
+
+Internal note:
+- Website installer files are hosted outside GitHub Release.
