+* Upgrade digital CNN to v8.3.0  (added new type of digits)
+
+* Internal update: TFlite (v2.5), esp32cam, startup sequence
+
+* Rollback to espressif v2.1.0, as v3.2.0 shows unstable reboot
+
+* Bugfix: WLan-passwords, reset of hostname
+
+
+##### 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
+* Improved SD-card handling (increase compatibility with more type of cards)
+
+##### 6.5.0 Image Processing in Memory - (2021-03-25)
+
+* Upgrade digital CNN to v8.2.0  (added new type of digits)
+* Supporting alignment structures in ROI definition
+* Bug fixing: definition of  hostname in `config.ini`
+
+##### 6.4.0 Image Processing in Memory - (2021-03-20)
+
+* Additional alignment marks for settings the ROIs (analog and digit)
+* Upgrade analog CNN to v7.0.0 (added new type of pointer)
+
+##### 6.3.1 Image Processing in Memory - (2021-03-16)
+
+* NEW: 6.3.1: bug fixing in initial edit reference image and `config.ini` (Spelling error in `InitialRotate`)
+* Initial setup mode: bug fixing, error correction
+* Bug-fixing
+
+##### 6.2.2 Image Processing in Memory - (2021-03-10)
+
+* NEW 6.2.2: bug fixing
+* NEW 6.2.1: Changed brightness and contrast to default if not enabled (resolves to bright images)
+* Determination of fixed illumination settings during startup - speed up of 5s in each run
+* Update digital CNN to v8.1.1 (additional digital images trained)
+* Extended error message in MQTT error message
+
+
+* Image brightness is now adjustable 
+
+
+* Bug fixing: minor topics 
+
+
+##### 6.1.0 Image Processing in Memory - (2021-01-20)
+
+* Disabling of analog / digital counters in configuration 
+* Improved Alignment Algorithm (`AlignmentAlgo`  = `Default`,  `Accurate` , `Fast`)
+* Analog counters: `ExtendedResolution` (last digit is extended by sub comma value of CNN)
+* `config.ini`: additional parameter `hostname`  (additional to wlan.ini)
+* Switching of GPIO12/13 via http-interface: `/GPIO?GPIO=12&Status=high/low`
+* Bug fixing: html configuration page, wlan password ("=" now possible)
+
+##### 6.0.0 Image Processing in Memory - (2021-01-02)
+
+* **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
+* 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`
+* Increased stability (internal image and camera handling)
+* Bug fixing: edit digits, handling PreValue, html-bugs
