-##### Rolling - (2021-01-01)
 
-* Increased stability (internal image handling)
-* Disabled `CheckDigitIncreaseConsistency` in default configuration - must now be explicit enabled if needed
-* Bug fixing: `message`-directory was missing on SD card, html: minor bug in edit digital/analog
 
-2020-12-31
+##### Rolling - (2021-01-05)
 
-* Bug-Fixing: internal change of camera handling to avoid reboots
+* Configuration: simple enabling / disabling of analog counters 
 
-2020-12-29
+* Alignment Algorithm: implementation of 3 alignment options (`AlignmentAlgo`)
 
-* MQTT: LWT (Last Will Testament) implemented: "connection lost" is written to the error topic in case of connection lost (`TopicError`)
+  * `Default` = know algo based on 1 channel SAD (square average difference) - using only the red channel
+  * `Accurate` = using all 3 color channels (3x slower)
+  * `Fast` = alignment only on first run, afterward only detection of shift of image by comparing SAD-values
+  * Time comparison for reference images with 2 times ~2000 pixel²: 
+    * Default ~40 s/run, Accurate: 1:40 min/run, **Fast: 7 s/run**
+    * `Fast` Option allows must faster value updates (up to 2 per Minute) 
 
-2020-12-29
+* Configuration of hostname in config.ini: new parameter `hostname` in section `System`
 
-* Parameter `TimerServer` added to `config.ini`
-* Update digital CNN to v7.2.1 (additional digital images trained)
-* Bug fixing: 
-  * edit digits: log images could not be enabled (html-page update)
-  * PreValue: no reboot necessary to use / take newly set pre-values
+* Switching of GPIO12/13 via http-interface:

-* Major change: no need of SD card for image processing anymore (all in memory)
-  
-  * 95% less SD card writing
-  * SD use: mainly reading of data (config, html, tflite parameters), only log files and prevalue write on SD card anymore
-  * Need to limit camera resolution to VGA (due to memory limits)
-  
-* New Feature: setting of time server in `config.ini`
+* Bug fixing: html configuration page
+
+* based on Master v6.0.0 (2021-01-02)
 
-  ```
-  [System]
-  TimeServer = fritz.box

-* Bug fix: corrected handling of out commented analog pointer ROIs
 
+##### 6.0.0 Image Processing in Memory - (2021-01-02)
 
-2020-12-07
+* **Major change**: image processing fully in memory - no need of SD card buffer anymore

+  * Need to limit camera resolution to VGA (due to memory limits)

+* MQTT: Last Will Testament (LWT) implemented: "connection lost" in case of connection lost to `TopicError`
 
+* Disabled `CheckDigitIncreaseConsistency` in default configuration - must now be explicit enabled if needed
 
-* Improvement: internal file handling
+* Update digital CNN to v7.2.1 (additional digital images trained) 
 
+* Setting of arbitrary time server in `config.ini`

+* Option for fixed IP-, DNS-Settings in `wlan.ini`
 
-* Option for fixed IP settings in `wlan.ini` - description see inside file
+* Increased stability (internal image and camera handling)
 
-* based on v5.0.0 (2020-12-06)
+* Bug fixing: edit digits, handling PreValue, html-bugs
 
   
 
 ##### 5.0.0 Setup Modus - (2020-12-06)
 
-* Implementation of intial setup modus for fresh installation
+* Implementation of initial setup modus for fresh installation
 
 * Code restructuring (full compatibility between pure ESP-IDF and Platformio w/ espressif)
