 ### Changed
 
+- Shell
+    - based on ptpython 3
+        - integration with asyncio with aiogevent
+    - starts in monochrome mode
+- relative scans (dscans) translated to absolute scans in data saving
+- ICEPAP motor controller: better error message if connection cannot be established
+    - raises CommunicationError exception
+- Lima
+    - '.use_background_substraction' is replaced by 'use_background' True/False, and 'background_source'image/file
+- progress bar refactoring
+    - new progress bar based on tqdm, avoid memory leak
+    - progress bar is no more intertwined with scan chain
+- ct output: refactoring of formatting code
 - Flint
     - When Flint is not fast enough to reach data from Redis, NaN values
       are used in order to keep the data alignment

 ### Fixed
 
+- Motion hook: post_scan is now executed after motor moved back to original position in case of 'dscan'
+- MCA
+    - better identification of communication errors
+    - when server is restarted, reconfigures device automatically
+    - block size adjusts automatically for Mercury and FalconX

+    - use redis to determine last access time
+- CalcMotorController: avoid recursive calls in '_real_position_update'
+- Display of Alias column in lscnt()
+- Measurement Group
+    - fix counters returned in random order
 - Flint
     - Fix initial curve plot selection in order to properly reuse user selection
     - Fixed slow rendering occurred on live curves and scatters with fast scans

 ### Removed
 
+- import of SpecClient_gevent in spec communication module
+    - as a consequence, "spec array" type is not supported
+- .statistics for scans
+    - was source of a memory leak
+    - for now: replaced by debugging with yappi
+    - equivalent, graphical version based on work by Linus before he left will be proposed
