+Important user-visible changes:
+- Improve the Python usability (stability and documentation).
+ - A nasty synchronization bug was ironed out, see also below.
+ - Python's doc was organized as a separate tree, now integrated with C++.
+ - C bindings of S4U were not part of the doc.
+ - The C++ doc was also improved as methods are now split by theme.
+- Further deprecate MSG: you now have to pass -Denable_msg=ON to cmake.
+ - This is mandatory to use the Java bindings.
+ - OFF by default; The plan is to completely remove MSG by 2020Q4 or 2021Q1.
+- SimDAG++: Automatic dependencies on S4U activities (experimental)
+ - Some features are already implemented but not all of them
+ - Cannot block an activity until it's scheduled on a resource
+ - No heterogeneous wait_any() that would mix Exec/Comm/Io activities.
+ - See examples/s4u/{io,exec,comm}-dependent for what's already there.
+
+
General:
