-SimGrid (3.24.1) NOT RELEASED YET (v3.25 expected December 22. 2029, 04:19 UTC)
+SimGrid (3.25.1) UNRELEASED (target: March 20 2020 or v3.26 on 3/26/20)
+
+Important user-visible changes:
+- 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 
+ should not cause too much performance hit. It can change some simulation 
+ timings if simulation was skipping a lot of small events (which was actually 
+ an issue of said simulation). The value can still be changed back using
+ --cfg=surf/precision:1e-5
+
+General:
+- LTO is now enabled for Intel/clang compilers.
+- LTO behavior on GCC can be parametrized 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).
+
+C interface:
+ - Many MSG tests were converted to the new S4U's interface in C, that
+   was extended for that.
+
+Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
+ - FG#43: xbt::random needs some care
+ - FG#48: The Impossible Did Happen (yet again)
+ - FG!24: Documentation and fix for xbt/random
+ - GH#139: Allow pthread creation in SMPI

   - Python's doc was organized as a separate tree, now integrated with C++.
   - C bindings of S4U were not part of the doc.
   - The C++ doc was also improved as methods are now split by theme.
-- Further deprecate MSG: you now have to pass -Denable-MSG=ON to cmake.
-  - The plan is to completely remove MSG by the end of 2020.
