 ------
+## Coming next
 
+* Automated update of the neural network file (tflite) to make the learing of additional pictures much easier and automated (GitHub action)
+* New "hyprid" neural network for digital numbers --> allowing the detection of intermediate states ("ring between two numbers") as a subdigit
+
+
+------
+## Change log
 ### Known Issues
 
 * slow response of web server during picture analysis
 * spontaneous reboots (mostly due to html access during image processing) - self recovery implemented
 
-------
-
 **General remark:** Beside the `firmware.bin`, typically also the content of `/html` needs to be updated!

-##### 6.6.1 Image Processing in Memory - (2021-04-05)
 
-* NEW 6.6.1: failed SD card initialization indicated by fast blinking LED at startup

-##### 6.5.0 Image Processing in Memory - (2021-03-25)
+- **Bug Fix MQTT problem**
+- Issue: 
+  - Changing from v9.x to 10.x the MQTT-paramter "Topic" was renamed into "MainTopic" to address multiple number meters
+    This renaming should have been done automatically in the background within the graphical configuration, but was not working. Instead the parameter "Topic" was deleted and "MainTopic" was set to disabled and "undefined".
+- ToDo
+  - Update the `html.zip`
+  - If old `config.ini` available: copy it to `/config`, open the graphical configuration and save it again.
+  - If old `config.ini` not available: reset the parameter "MainTopic" within the `config.ini` manually 
+  - Reboot
