-SimGrid (3.9) NOT RELEASED; urgency=low
+SimGrid (3.10) NOT RELEASED; urgency=low
+
+ XBT:
+ * Our own implementation of getline is renamed xbt_getline, and gets
+   used even if the OS provide a getline(). This should reduce the
+   configuration complexity by using the same code on all platforms.
+
+ Java:
+ * Reintegrate Java to the main archive as desynchronizing these
+   package is not acceptable anymore (Java is now considered stable)
+ * Bugfix: Task.setDataSize() only changed the C world, not the value
+   cached in the Java world
+
+ SMPI:
+ * Improvements of the SMPI replay tool:
+   - Most of the collective communications are now rooted in the same process as
+     in the original application.
+   - Traces now rely on the same MPI datatype as the application (MPI_BYTE was 
+     used until now). Multiple datatypes can now be used in a trace.
+   - The replay tool now supports traces produce either by TAU or a modified 
+     version of MPE.
+   - Bug Fix: the compute part of the reduce action is now taken into account.

+SimGrid (3.9) stable; urgency=low
+
+ The Grasgory release: GRAS is really dead now.
+
+ * Complete overhaul of the internal host structures scheme.
 
  GRAS:
- * GRAS is definitely dead now.
+ * If you use GRAS, you should stay at SimGrid 3.5 (at most) since it
+   was considered as experimental and badly maintained since then.
+ * Keeping it was thus a trap to our potential users, that could take
+   it instead of MSG or SMPI by mistake despite is pity state.
+ * GRAS seems to have very few users (if any), and no one volunteered
+   to maintain it further. It also induces a lot of XBT code (for
+   portability sake), that must be maintained too.
+ * For all these reasons, we killed GRAS. If someone wants to revive it
+   in the future, don't cry, our git history still remembers of GRAS.
+
+ Documentation:
+ * Major overhaul. Merge our documentation again as time proved that
+   splitting it was really not helping our users.
+ * Further improve the developer documentation to help newcomers
+   hacking on SimGrid itself. The user documentation (and in
+   particular, the beginner documentation) is still in a sorry state.
 
  SMPI:
  * Now works on Windows too!
  * Much more extensive test suite, from MPICH
 
+ SIMDAG:
+ * Add a new loader (SD_PTG_dotload) that creates a parallel task graph
+  (i.e., a DAG whose nodes are parallel tasks) from a dot file. Creates a
+  dynar of SD_TASK_COMP_PAR_AMDAHL and SD_TASK_COMM_MXN_1D_BLOCK tasks.
+ * Bug fix: let task be scheduled when the last dependency to be solved is
+   a control dependency.
+ * Remove SD_load_environment_script function.
+   Use the C sg_platf function if you want to declare a platform
+   programmatically.
+
  MSG:
  * New function: MSG_process_get_number()
+ * Old function documented: MSG_config()
+ * Remove MSG_load_platform_script function
+   Use the C sg_platf function if you want to declare a platform
+   programmatically.
+
+ SURF:
+ * Change the default value of the TCP_gamma constant (maximal size of TCP
+   congestion window) to a more realistic 4MiB value. If you notice changes in
+   your simulation results, you can fall back to the previous 20k tiny window
+   by adding --cfg=network/TCP_gamma:20000 on command line.
+ * (Hopefully) fix a bug wrt periodic availability and state traces
+ * Bug fix: use default values at start when first event in availability/state
+   trace is not at time 0.
+
+ PLATFORM:
+ * remove the "new_" part of function name sg_platf_new_trace_connect
+   (resulting in sg_platf_trace_connect), since it does not create
+   anything new
 
  XBT:
  * Kill synchronized dynars, and xbt_dynar_dopar(). We cannot think of a
-   usecase where it's really mandatory, and maintaining it was a pain in
-   our codebase.
+   use case where it's really mandatory, and maintaining it was a pain in
+   our code base.
+ * New: xbt_fifo_search(), search an item with a user-provided
+   comparison function instead of dumb pointer comparison.
+
+ LUA:
+ * Fix the lua deployment:
+   Use `simgrid.init_application()` before deployment instead of
+   `simgrid.msg_register_application()` after.
+
+ TRACING:
+ * Transfer the tracing files into the corresponding modules.
