 SimGrid (3.21) NOT RELEASED (Release Target: September 23. 2018, 1:54 UTC)
 
+S4U new features:
+ - s4u::Io: IOs go asynchronous as activities. This comes with new methods in the
+   s4u::Storage class: 
+     - io_init(sg_size_t, s4u::Io::OpType) to create a READ or WRITE asynchronous
+       IO operations that can be started, waited for, or canceled as a regular
+       activity.
+     - read_async(sg_size_t) and write_async(sg_size_t) which are wrappers on 
+       io_init() + start()
+
 Tracing:
  - Rename 'power' and 'power_used' variables into 'speed' and 'speed_used'
  - New host variable: 'core_count'
- 
+
 XBT:
  - Remove xbt_os_thread_specific features
  - Remove portability wrapper to condition variables
+ - Remove xbt_os_thread_yield()
