 SimGrid (3.9) NOT RELEASED; urgency=low
 
+ The Grasgory release: GRAS is really dead now.
+
+ GRAS:
+ * 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.
+
  SMPI:
  * Now works on Windows too!
  * Much more extensive test suite, from MPICH

  MSG:
  * New function: MSG_process_get_number()
 
+ 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.
+
  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.
+ * New: xbt_fifo_search(), search an item with a user-provided
+   comparison function instead of dumb pointer comparison.
