+## [Unreleased]
+
+xxx
+
+### Update Procedure
+
+Update Procedure see [online documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/#update-ota-over-the-air)
+
+:bangbang: Afterwards you should force-reload the Web Interface (usually Ctrl-F5 will do it).
+
+### Changes
+
+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`.
+
+Beside of the parameter change and the bugfix listed below, no changes are contained in this release!
+
+If you want to revert back to `v14` or earlier, you will have to revert the migration changes in `config.ini` manually!
+
+#### Added
+
+-   Additional interface to InfluxDB Version 2 upwards
+-   Updated the Hybrid CNN network to `dig-cont_0610_s3`
+-   :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!
+
+#### Changed
+
+-   [#2023](https://github.com/jomjol/AI-on-the-edge-device/pull/2023) Migrated Parameters
+-   Removed old `Topic` parameter, it is not used anymore
