+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.
+
+C binding and interface:
+ - Rename (lowercase) functions sg_actor_get_PID, sg_actor_get_PPID, sg_actor_by_PID.
+
+Documentation:
+ - New section: Configuring the logs from the command line.
+ - New section: Programming API of logs.
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GF: issues on GForge; GH: issues on GitHub)
+- FG#37: Parallel tasks are limited to 1 core per host
+- GH#343: Wrong consumed energy when an exec timeouts

    This can cause some troubles if codes are already overriding these. If this

    help, but will make this feature unusable.
