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()
+ - Fully reimplement auto_restart mechanism that was utterly broken
+ (fix #22, #131 and #281 that were all very related)
+ - When creating an actor from a function and its parameters,
+ move-only parameters are not allowed anymore, as it would prevent
+ the actor to be restartable if its parameters are consumed on run.
+
+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()
+
+Fixed bugs:
+ - #22: Process autorestart seem to only work with CAS01 cpus
+ - #93: simgrid should not eat --help
+ - #131: Java : autostart does not work
+ - #264: Add ptask L07 resource tracing
+ - #271: Dynamic and manual replay of SMPI traces
+ - #279: Breakpoints option uses time deltas instead of absolute time
+ - #281: Daemonized actor no longer daemonized after an auto-restart
+ - #282: TIT convertor erase traces when using absolute path in the trace list file
+ - #285: segfault when a s4u actor kills itself with msg process tracing activated
+ - #286: Pajé traces are not exposing the number of cores
+ - #287: Command-line parsing should stop when encountering '--'
+ - #288: MPI_Init(NULL, NULL)
