  General:
   - Stop setting random seed with srand48() at initialization.
 + - Use addr2line as a fallback for stacktraces when backtrace is not available.
+  - Build option -Denable_documentation is now OFF by default.
  
  XBT:
   - New log appenders: stdout and stderr. Use stdout for xbt_help.
@@@ -17,8 -17,10 +18,10 @@@ Model-checker
   - Remove option 'model-check/record': Paths are recorded in any cases now.
  
  Fixed bugs (GH=GitHub; FG=FramaGit):
+  - FG#7: simple cmake call requires doxygen
   - FG#10: Can not use MSG_process_set_data from SMPI any more
   - FG#11: Auto-restart actors forget their on_exit behavior
+  - FG#12: -Denable_lto=OFF doesn't disable LTO
   - GH#133: Java : a process can run on a VM even if its host is off
   - GH#326: Valgrind-detected error for join() when energy plugin is activated
