- The "sprint cleanups (before the next Big Project kicks in)" release.

+
+ CMAKE:
+ * Remove option custom_flags. Now use environment variables CFLAGS
+ and LDFLAGS.
+
+ MSG:
+ * Add an experimental interface to manipulate VMs. They are mainly
+ process groups with very few intrinsic semantic, but they should
+ allow you to build the semantic you want easily.
+
+ Simix:
+ * Bug fixes around the resource failures: don't let the processes
+ survive the host they are running onto
+
+ SimDag:
+ * New type of typed tasks SD_TASK_COMP_PAR_AMDAHL that represents a
+ parallel task whose initial work is distributed among host according
+ to the Amdahl's law. Such tasks are created with a parameter alpha
+ that corresponds to the non-parallelizable part of the computation.
+
+ Before calling SD_task_schedulel or SD_task_schedulev, the
+ SD_task_distribute_comp_amdahl function has to be called with the
+ desired number of workstations. The filling of computation_amount and
+ communication_amount (actually empty) structures is then done
+ seamlessly.
+ * New function SD_workstation_dump to display various information
+
+ XBT:
+ * Functions xbt_dict_hash() and xbt_dict_hash_ext() are made public,
+ and renamed to xbt_str_hash() and xbt_str_ext()._

+SimGrid (3.7.1) stable; urgency=low
+
+ MSG:
+ * Restore the prototype of MSG_process_create_with_environment() to
+ the pre-3.7 situation by removing the kill_time argument.
+ * Add a MSG_process_set_kill_time() function instead.
+
+ SURF:
+ * Fix weird behaviors when dealing with parallel tasks.
+
+ WINDOWS:
+ * Simgrid is now built as a dll.
+ * Simgrid-java now works on Windows.
+ * Simgrid-Java is now included into Windows package.
+
+ MacOS:
+ * First pre-build package for MacOSX.
+
+ Build System:
+ * Fix compilation when using MSG_USE_DEPRECATED.
+ * Fix some compilation issues on Macs and Windows.
+ * Reduce the number of failing tests on exotic systems, like Debian/Hurd.
+ * Environment variables CFLAGS and LDFLAGS are now honored by cmake.
+
+ We discovered that the Lua console is broken, but we are missing the
+ manpower to fix it right now. The problem existed in 3.7 too, so we
+ are not blocking the release for that. Sorry if you depended on this
+ feature, any help would be really welcome.

Turn model-checking OFF if simulation performance matters to you.
Not enabling it at runtime is not enough, disable it in cmake.

GRAS:

messages from the network. It allows to overlap communication and
