-### Changes
+:bangbang: Afterwards you should force-reload the Web Interface (usually Ctrl-F5 will do it)!
 
-This release only migrates some parameters, see #2023 for details and a list of all parameter changes.
-The parameter migration happens automatically on the next startup. No user interaction is required.
-A backup of the config is stored on the SD-card as `config.bak`.
+:bangbang: Afterwards you should check your configuration for errors!
 
-Beside of the parameter change and the bugfix listed below, no changes are contained in this release!
+### Changes
 
-If you want to revert back to `v14` or earlier, you will have to revert the migration changes in `config.ini` manually!
+For a full list of changes see [Full list of changes](https://github.com/jomjol/AI-on-the-edge-device/compare/v15.0.3...v15.1.0)
 
 #### Added
+- The Configuration page has now tooltips with enhanced documentation
+- MQTT:
+    - Added `GJ` (`gigajoule`) as an energy meter unit
+    - Removed State Class and unit from `raw` topic
+    - Various Improvements (Only send Homeassistant Discovery the first time we connect, ...) (https://github.com/jomjol/AI-on-the-edge-device/pull/2091
+- Added Expert Parameter to change CPU Clock from `160` to `240 Mhz`
+- SD card basic read/write check and a folder/file presence check at boot to indicate SD card issues or missing folders / files ([#2085](https://github.com/jomjol/AI-on-the-edge-device/pull/2085))
+- Simplified "WIFI roaming" by client triggered channel scan (AP switching at low RSSI) -> using expert parameter "RSSIThreshold" ([#2120](https://github.com/jomjol/AI-on-the-edge-device/pull/2120))
+- Log WLAN disconnect reason codes (see [WLAN disconnect reasons](https://jomjol.github.io/AI-on-the-edge-device-docs/WLAN-disconnect-reason))
+- Support of InfluxDB v2 ([#2004](https://github.com/jomjol/AI-on-the-edge-device/pull/2004))
 
--   Additional interface to InfluxDB Version 2 upwards
--   Updated the network and corrected problems with quantized version:
-  -   Hybrid CNN network to `dig-cont_0611_s3` 
-  -   Analog CNN network to `ana-cont-11.0.5` and `ana-clas100-1.5.7`
-  -   Digital CNN network to `dig-class100-1.6.0`
-
--   :bangbang:  Update Camera driver: contrast, brightness and saturation now working
-   
-    :bangbang:  **Attention**: this can effect old version as well, because there not all settings were effective!
-    
-- Option to change the CPU frequency (stability vs. speed)
-- Homeassistant: add GJ (giga joule)
-- Implementes "poor mans" wifi roaming to connect to the nearest access point
-- Additional startup checks (sd card, folder / file prescence, boot phase)
-- Internal updates (log file handling, boot phase)
 
 #### Changed
-
--   [#2023](https://github.com/jomjol/AI-on-the-edge-device/pull/2023) Migrated Parameters
--   Removed old `Topic` parameter, it is not used anymore
--   Internal optimization of memory usage to enable new features
--   Improve MQTT
+- Updated models (tflite files), removed old versions (https://github.com/jomjol/AI-on-the-edge-device/pull/2089, https://github.com/jomjol/AI-on-the-edge-device/pull/2133)
+  :bangbang: **Attention:** Update your configuration!
+    -   Hybrid CNN network to `dig-cont_0611_s3` 
+    -   Analog CNN network to `ana-cont-11.0.5` and `ana-clas100-1.5.7`
+    -   Digital CNN network to `dig-class100-1.6.0`
+-   Various Web interface Improvements/Enhancements:
+    - Restructured Menu (Needs cache clearing to be applied)
+    - Enhanced `Previous Value` page
+    - Improved/faster Graph page
+    - Various minor improvements
+    - ROI config pages improvements
+    - Improved Backup Functionality
+- Added log file logs for Firmware Update
+- Improved memory management (moved various stuff to external PSRAM, https://github.com/jomjol/AI-on-the-edge-device/pull/2117)
+- Camera driver update: Support of contrast and saturation ([#2048](https://github.com/jomjol/AI-on-the-edge-device/pull/2048))   
+  :bangbang:  **Attention**: This could have impact to old configurations. Please check your configuration and potentially adapt parametrization, if detection is negativly affected.
+- Improved error handling and provide more verbose output in error cases during boot phase ([#2020](https://github.com/jomjol/AI-on-the-edge-device/pull/2020))
+- Red board LED is indicating more different errors and states (see [Status LED Blink Codes](https://jomjol.github.io/AI-on-the-edge-device-docs/StatusLED-BlinkCodes))
+- Logfile: Print start indication block after time is synced to indicate start in logfile after a cold boot
+- `Image Quality Index`: Limit lower input range to 8 to avoid system instabilities
 
 #### Fixed
+- Various minor fixes
+- Added State Class "measurement" to rate_per_time_unit
+- GPIO: Avoid MQTT publishing to empty topic when "MQTT enable" flag is not set
+- Fix timezone config parser
+- Remote Setup truncated long passwords (https://github.com/jomjol/AI-on-the-edge-device/issues/2167)
 -  Problem with timestamp in InfluxDB interface
 
 #### Removed
-
 -   n.a.
