CHANGELOG.md ~~schainpy/CHANGELOG.md~~ renamed +5 -3

              ## CHANGELOG:
              ### 3.0
-             * Python 3.x compatible
-             * New architecture with multiprocessing and IPC communication
-             * Add @MPDecorator for multiprocessing Units and Operations
+             * Python 3.x & 2.X compatible
+             * New architecture with multiprocessing support
+             * Add @MPDecorator for multiprocessing Operations (Plots, Writers and Publishers)
              * Added new type of operation `external` for non-locking operations
              * New plotting architecture with buffering/throttle capabilities to speed up plots
+             * Clean controller to optimize scripts (format & optype are no longer required)
+             * New GUI with dinamic load of Units and operations (use Kivy framework)
              ### 2.3
              * Added support for Madrigal formats (reading/writing).
