 Python:
  - We are excited to introduce the SimGrid/S4U interface to your neighborhood
  - Not complete yet: asynchronous activities (amongst others) are still missing
- - Still ongoing: the interface may change a bit in the future (please
-   report any glitches), but it seems rather fast and reliable already. 
- - Forget about Java now (and soon about C++)

-Core:
- - Replace our own code to display a backtrace (that was forking addr2line)
+ - Still ongoing: the interface may change in the future. We need more
+   testers! Please report any glitches.
+ - No new project using Java should start now. Please switch to Python.
+
+General:
+ - Some of the internal cleanups may lead to speed improvements:
+   - The hard limitation on the amount of simulated actors with
+     Java+Mac was removed. Now, the  available memory is the only limit.
+   - Our refcounting was tidyied, leading to 10% speedups in some cases.
+ - We are still working on making our code robust to the actor kills
+   and hosts' churn. Things are improving, but it's not perfect yet.
+ - Replaced our own code to display a backtrace (that was forking addr2line)
    with the Boost.Stacktrace library.
    You won't see your backtraces without this optional dependency.
  - Bump cmake dependency to 3.5 (provided by Ubuntu 16.04).
- - Stop setting random seed with srand() at initialization.
+ - Stop setting random seed with srand() at initialization.

  - In <host> and <peer>, 'availability_file' is now 'speed_file'.

    Now use (int,void*) callbacks instead of (void*,void*) ones.
    The implementation was ways too messy to actually work, I guess.
 
+SMPI:
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache 
+   too often and provide more accurate timings.

 XBT:
  - Drop sg_cmdline. Please use xbt_cmdline instead.
  - Drop the C xbt_os_mutex_t; Use the C++11 std::mutex.
