+SimGrid (3.14) UNRELEASED; urgency=low
+
+ Documentation
+ * The whole documentation was reworked and reorganized. There is
+   still much room for improvement here, but we're on it.
+
+ Infrastructure
+ * We now need python3 for our testing infrastructure.
+
+ SMPI
+ * Privatization is now activated by default in smpirun
+   You can turn it off with -no-privatize if something goes wrong.
+
+ * Call-location tracing for SMPI.
+   You can add the exact location (filename / linenumber) of an MPI call to 
+   your trace files and slow down or speed up the simulation between two 
+   consecutive calls by using an adjustment file (see the documentation).
+
+ * Fixed computation of timings for MPI_Send, MPI_Recv & possibly also others
+   We've found a bug that prevented SMPI to account for MPI_Send, MPI_Recv
+   and others (in some cases) in a correct way. That is, the smpi/os, smpi/or
+   values were ignored in some cases. The timings of these functions can now
+   be significantly different.
+
+ * smpi/cpu-threshold:-1 should become smpi/simulate-computation:no
+   smpi/running-power    is renamed to smpi/host-speed
+
+ New functions and features
+ * MSG_parallel_task_execute_with_timeout, to timeout computations.
+
+ Dropped / renamed functions and features
+ * msg_mailbox_t and associated functions. Use s4u::Mailbox instead.
+   - MSG_mailbox_is_empty() -> Mailbox::empty()
+   - MSG_mailbox_front() -> Mailbox::front()
+   - MSG_mailbox_get_by_alias() -> simgrid::s4u::Mailbox::byName(name)
+   - MSG_mailbox_get_task_ext() -> MSG_task_receive_ext()
+   - MSG_mailbox_get_task_ext_bounded -> MSG_task_receive_ext_bounded
+   - MSG_host_(get/set)_params -> MSG_vm_(get/set)_params
+
+ * Task affinity. Its intended behavior (that was very badly tested
+   and probably not really working) was deceiving what most users
+   would have hoped here.
+ * xbt_os_sem_get_value: unused internally, deprecated on OS X El Capitan
+
+ XML:
+ * Add Exa- and Peta- units such as EiB, EB, Eib, Eb for size, and
+   EiBps, EBps, Eibps, Ebps for bandwidth. 
+   They may become useful to some lucky ones.
+   
+ Java:
+ * New functions: msg.Comm.waitAll() and msg.Comm.waitAny()
+ * ex/app_tokenring: new example, very similar to the MSG Token Ring
+ * ex/async_waitAll: new example, on asynchronous communications
