+ 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.

+
+SimGrid (3.7) stable; urgency=low
+
+ The "spring cleanups (before the next Big Project kicks in)" release.
+
+ Models:
+ * We can specify the SMPI latency/bandwidth factor with command line
+ add --cfg=smpi/bw_factor:"threshold0:value0;...;thresholdN:valueN"
+ or add --cfg=smpi/lat_factor:"threshold0:value0;...;thresholdN:valueN"
+ You can also use the "config tag" from platform file by adding this line
+ <prop id="smpi/bw_factor" value="threshold0:value0;...;thresholdN:valueN"></prop>
+ (see "example/platforms/tag_config.xml" to use "config tag").
+ Note that the command line supersedes the platform file configuration.
+ * Change the correction factors used in LMM model, according to
+ the latest experiments described in INRIA RR-7821.
+ Accuracy should be improved this way.
+ * Use the partial invalidation optimization by default for the
+ network too. Should produce the exact same results, only faster.
+ * Major cleanup in surf to merge models and split some optimization
+ mechanisms from the core of the models. As a result you can now
+ specify which model to use (e.g., --cfg=network/model:LV08
+ --cfg=cpu/model:Cas01) and which optimization mode to use
+ (e.g., --cfg=network/optim:lazy --cfg=cpu/optim:TI).
+ Incompatible combinations should err at initialization. See
+ --help-models for the list of all models and optimization modes.
+ * The CLM03 workstation model was dropped for simplicity because it
+ used the deprecated CM02 network model. Use default instead.
+ * Rename the TCP_gamma configuration option to network/TCP_gamma
+ * Rename the coordinates configuration option to
+ network/coordinates, and document it
+ * Use now crosstraffic keyword instead of the terribly misleading
+ fullduplex keyword. It is activated by default now in the current
+ default model, use --cfg=network/crosstraffic:0 to turn it off.
+ * Ongoing refactoring the model parsing to make XML files optional
+ See include/simgrid/platf.h for details (still to be completed)
+
+ MSG:
+ * Major overhaul of the documentation. Almost instructive now :/
+ * Deprecate the use of m_channel_t mechanism like MSG_task_{get,put}
+ functions and friends. This interface was considered as
+ deprecated since over 2 years, it's time to inform our users that it is.
+ Switch to MSG_task_{send,recv} instead, or compile SimGrid command line
+ 'cmake -Dcustom_flags="-DMSG_USE_DEPRECATED" .' if you really need to
+ use these (crappy) functions in your code.
+ These functions will be removed soon. Stop using them now.
+ * Deprecate MSG_get_host_{table,number}
+ Implement MSG_hosts_as_dynar() instead.
+ * Implement MSG_processes_as_dynar() (Closes gforge #13642)
+ * Remove the public field msg_host_t->name. Use MSG_host_get_name()
+
+ Simix:
+ * Stabilize the parallel execution mode of user contexts
+ * Introduce configuration variables to control parallel execution:
+ - contexts/synchro: Synchronization mode to use when running
+ contexts in parallel (either futex, posix or busy_wait)
+ - contexts/parallel_threshold: Minimal number of user contexts
+ that must be part of a scheduling round to switch to parallel
+ execution mode (raw contexts only)
+ * Fix bugs that prevented to use suspend/resume along with
+ synchronization structures.
+ * Fix bugs in process termination that lead to invalid memory access
+ in very specific conditions.
+
+ SURF:
+ * Introduce a parallel mode for the models (controlled by surf/nthreads
+ configuration item). In our tests, running the models in parallel
+ never lead to any speedups because they are so fast that the gain
+ of computing each model in parallel does not amortizes the
+ synchronization costs, even when ultra fast futexes are used.
+ This is released anyway because YMMV.
+
+ SimDag:
+ * Performance boost by using a swag internally to compute the set of
+ tasks that are finished and should constitute the return value of
+ SD_simulate.
+
+ SMPI:
+ * Enable it by default now that it is considered rather stable.
+
+ TRACE:
+ * Documentation of the tracing functions.
+ * Performance gains when tracing categorized/uncategorized resource
+ utilization by avoiding calls to get route when updating resource
+ variables. LMM constraints are being used instead.
+ * API changed to set task categories. Use MSG_task_set_category instead
+ of TRACE_msg_set_task_category, and SD_task_set_category instead
+ of TRACE_sd_set_task_category. They only work if ENABLE_TRACING is ON.
+ * Bugfix for graphicator, routes not correctly obtained, memory leaks
+ * Examples for link user variables added (see at examples/msg/tracing/)
+ * Deprecated function TRACE_msg_set_process_category completely removed
+ * Trace header updated according to the latest Paje file format
+ * Tracing network lazy updates, no longer obligate users to use full updates
+ * --cfg=tracing/platform:1 also registers power/bandwidth variables
+ * Experimental: let user code declare/set/push/pop application states for hosts
+ * API changed to allow the manual creation of graph configuration files
+ for Triva. See TRACE_get_node_types() and TRACE_get_edge_types().
+
+ Lua:
+ * Improve the API of Lua MSG bindings, using the Lua spirit.
+ * Each simulated process now lives in its own Lua world (globals are
+ automatically duplicated). It helps writing simulators. Will allow
+ to run Splay programs within SimGrid in the future.
+ * Add a Chord example in Lua, equivalent to the MSG one.
+
+ MODEL-CHECKING:
+ * Start the implementation of a solution to express temporal
+ properties, not only local assertions. This is still an
+ experimental work in progress, stay clear from it to be safe.
