SimGrid (3.26.1) NOT RELEASED YET (v3.27 expected March 20. 2021, 09:37 UTC)
+User-visible changes:
+ - Removed some option aliases that were deprecated since v3.23 (June 2019)
+ - 'verbose-exit' is now 'debug/verbose-exit'
+ - 'simix/breakpoint' is now 'debug/breakpoint'
+ - 'clean-atexit' is now 'debug/clean-atexit'
+ - Removed all that was related to the "Storage" type in all APIs and bindings.
+ "Disks" have been introduced more than a year ago to replace them for the better.
+ It's time to finish this replacement.
+
+S4U:
+ - Define new template functions Mailbox::get_unique(), returning a std::unique_ptr.
+ - Functions Mailbox::get() and Mailbox::get_async() are now templated with the
+ type of the pointee. Untyped functions are deprecated. Use Mailbox::get<void>()
+ or Mailbox::get_async<void>() if you really want to play with void*.
+ - Unify the interface of Activity::on_{start/activity}
+ - New function: Comm::get_dst_data()
+ - New function: Comm::set_payload_size() to set the amount of bytes to simulate.
+ - New functions: Comm::sendto_{init,async} to initiate a communication
+ on between two (possibly remote) hosts.
+
+XBT:
+ - Drop simgrid::xbt::demangle. Please use boost::core::demangle instead.
+
+Documentation:
+ - New section: Configuring the logs from the command line.
+ - New section: Programming API of logs.

SimGrid (3.26) December 15. 2020
- smpicc/cxx/ff/f90 now will actually perform definition checks at link time. When
building shared libraries, this may cause issues, so environment variable
SMPI_NO_UNDEFINED_CHECK can be added to disable this.
- - most temporary files should now be created in /tmp dir (or equivalent).
+ - most temporary files should now be created in /tmp dir (or equivalent).
If this one does not allow execution of code (noexec flag), this may cause issues.
- Please use another tmp directory (using TMPDIR or equivalent system variable)

in this case.
Model-Checker:
allocations' size above which they are considered "shared" by default (as if
they were performed through SMPI_SHARED_MALLOC macros).
Default = 0 = disabled feature.
- Note : malloc, calloc and free are now overriden by smpicc/cxx by default.
+ Note : malloc, calloc and free are now overridden by smpicc/cxx by default.
This can cause some troubles if codes are already overriding these. If this
is the case, defining SMPI_NO_OVERRIDE_MALLOC in the compilation flags can
help, but will make this feature unusable.
