 ## CHANGELOG:
 
 ### 2.3
+* Added high order function `multiSchain` for multiprocessing scripts.
+* Added a new graphics processing unit `PlotterReceiver`. It is decoupled from normal processing sequence with support for data generated by multiprocessing scripts.
+* Added a CLI tool named `schain`. 
+* Command for GUI is now `schainGUI`.
+* Added suggestions when parameters are poorly written.
+* `Controller.start()` now runs in a different process than the process calling it.
+
+### 2.2.6
+* Graphics generated by the GUI are now the same as generated by scripts. Issue #1074
+* Numpy version updated.
 
 ### 2.2.5:
 * splitProfiles and combineProfiles modules were added to VoltageProc and Signal Chain GUI.
