 SimGrid (3.25.1) UNRELEASED (target: March 20 2020 or v3.26 on 3/26/20)
 
 Important user-visible changes:
+ - SimGrid now requires a compiler with C++14 support.
+   Sibling projects should upgrade their FindSimgrid.cmake
  - Surf precision default value is now 1e-9, instead of 1e-5. This was changed as
    several users had difficult to understand issues when using high bandwidth or
    small latency events. The new value was already the default for SMPI and

+New features:
+ - New routing 'WiFi' that makes it easier to specify a wifi network zone.
+ - New plugins: wifi_energy and link_load. See the associated examples.

+General:
+ - LTO is now enabled for Intel/clang compilers.
+ - LTO behavior on GCC can be parameterized using LTO_EXTRA_FLAG in cmake.
+   Setting it to "auto" will use all available cores, while setting it to n will
+   use n cores to speedup link step (usage: cmake -DLTO_EXTRA_FLAG=4).
+ - Remove obsolete option --cfg=contexts/parallel-threshold.
+ - Further improve the documentation.
