-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

+SimGrid (3.25) February 2. 2020 (aka 02 02 2020)
+
+The Palindrom Day Release.
Important user-visible changes:
- Improve the Python usability (stability and documentation).
- 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.
+- Further deprecate MSG: you now have to pass -Denable_msg=ON to cmake.
+ - This is mandatory to use the Java bindings.
+ - OFF by default; The plan is to completely remove MSG by 2020Q4 or 2021Q1.
- SimDAG++: Automatic dependencies on S4U activities (experimental)
- Some features are already implemented but not all of them
- Cannot block an activity until it's scheduled on a resource
- - Only Exec and Io so far. Comms are not handled yet.
- - No heterogeneous wait_any() that would mix Exec and Io activities.
- - See examples/s4u/{io-,exec-}dependent for what's already there.
+ - No heterogeneous wait_any() that would mix Exec/Comm/Io activities.
+ - See examples/s4u/{io,exec,comm}-dependent for what's already there.
