+SimGrid (3.15) UNRELEASED; urgency=low
+
+ - Rename NetCards to NetPoints.
+   This was intended to help NS3 users, but that's not a netcard.
+   That's a point in the routing algorithm, let's avoid wrong simplifications.
+
+ MSG
+ - New function: MSG_process_yield()
+ - Renamed MSG_energy_plugin_init() -> MSG_host_energy_plugin_init()
+   to make room for the upcoming network energy plugin.
+
+ Java
+ - Ensure that an actor can kill itself with Process::exit()
+ - Kill the obscure NativeException. Nobody want to survive the issues
+   it denotes, so use JniException that is a RuntimeException (not to
+   be catched explicitely).
+
+ S4U
+ - New callbacks:
+   - s4u::onPlatformCreated: right before the simulation starts
+   - s4u::onSimulationEnd: right after the main simulation loop
+   - s4u::onTimeAdvance: right after a clock change (time is discrete)
+   - s4u::Host::onSpeedChange: when the pstate is changed, or when an
+     event from the availability_file changes the avail speed.
+ - Links are now usable from s4u
+
+SimDag
+ - Backwards Compatibility breaks
+    - The SD_route_get_list and SD_route_get_size functions have been removed. 
+      They are replaced by the unique 
+         void sg_host_route(sg_host_t src, sg_host_t dst, xbt_dynar_t links)
+      The route from src to dst is built in the links dynar whose size can 
+      be obtained with xbt_dynar_length.
+ - The SD_route_bandwidth and SD_route_latency functions have been replaced by
+      sg_host_route_bandwidth and sg_host_route_latency. Macros ensure the 
+      backwards compatibility, but the new functions have to be preferred.
+ SMPI
+ - New algorithm for SMPI_SHARED_MALLOC: global, where all blocks are
+   mapped onto a unique file.
+
+ XBT
+ - Kill the fifo data container: we don't use it anymore.

+SimGrid (3.14.159) stable; urgency=low
+
+ The previous release was only a crude approximation of a Pi release;
+ this one should be a bit better.
+
+ - Revert a last minute change that broke on Mac OSX.
+ - Fix the changelog and NEWS files.
+ - Improve the documentation, in particular of the routing module.
+ - Integrate some patches flying around in Debian.

- Dropped functions and features
+ * 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

+ * VM properties. Since msg_vm_t are msg_host_t, just use

+ * 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.
