-SimGrid (3.14) UNRELEASED; urgency=low
+SimGrid (3.14) stable; 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.
+ * Model checking needs libevent
 
  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.)
+   consecutive calls by using an adjustment file (see the documentation).
 
- * Fixed computation of timings for MPI_Send, MPI_Recv but possibly also others
+ * 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
+
+ * smpi/grow-injected-times option to enable or disable multiplication of the 
+   timings injected in MPI_Iprobe, or MPI_Test. Enabled by default, which can 
+   make simulation less precise (but also much faster).
+
+ * smpirun script should be (much) faster for large deployments.
+
+ * SMPI tracing : fixed issue with poor matching of send/receives.
+
+ * Replay : Fix broken waitall
+
+ 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
+ * Don't pass the free_f parameter to property related functions:
+   - MSG_host_set_property_value()
+   - MSG_as_router_set_property_value()
+   - MSG_storage_set_property_value()
+ * VM properties. Since msg_vm_t are msg_host_t, just use
+   MSG_host_get_property_value() and friends
+ * VM I/O related things:
+   - Ignored parameter of vm_create: core_nb, disk_path and disk_size.
+   - Unimplemented save/restore methods
+ * MSG_as_router_get_property_value() was redundent with
+   MSG_environment_as_get_property_value(). 
+   - Removed MSG_as_router_*propert*() functions
+   - Added MSG_environment_as_set_property_value() for consistency
+ * xbt heterogeneous dictionnaries (created with xbt_dict_new()). 
+   Well, they are still there for now, but deprecated with a warning. 
+   Please switch to xbt_dict_new_homogeneous() before this is removed
+   for real.
+ * 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
+ * Option network/coordinates is now useless and should be dropped.
+ 
+ Storage: 
+ * Added option storage/max_file_descriptors to allow more than 1024 files opened
+
+ SURF:
+ * Added option maxmin/concurrency_limit to allow more than 100 processes per host
+ * Added Dragonfly topology support
+
+ 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
+
+ MSG:
+ * Memory usage should be decreased for simulations with a large number 
+  of processes. This also helps for SMPI.
