+SimGrid (3.13) UNRELEASED; urgency=low
+
+ The Easter Trim Release.
+
+ Backwards Compatibility breaks
+ - The option "model-check/sparse-checkpoint" was renamed to
+ "model-check/sparse_checkpoint" as we attempt to unify our naming
+ schemes.
+ - The option smpi/async_small_thres was renamed to smpi/async_small_thresh
+ as we attempt to unify our naming schemes.
+ - The option smpi/send_is_detached_thres was renamed to
+ smpi/send_is_detached_thresh as we attempt to unify our naming schemes.
+
+ - We removed support for writing your simulation in Lua; you can use
+ the Java bindings.
+
+
+ S4U
+ * s4u::Host is now the prefered public interface to the Host features.
+ sg_host_* functions are C bindings to the exact same behavior
+ MSG_host_* and SD_workstation_* are #define to the sg_host_* ones
+
+ MSG
+ * Kill all deprecated functions. They were deprecated since a few
+ releases anyway, and probably did not even compile anymore.
+
+ Simix
+ * simgrid::simix::kernel() is the closure callback. It ensures that
+ the lambda or closure passed as a parameter will run in kernel mode.
+ Every callbacks should be rewritten to that interface at some point.
+
+ Surf
+ * Reorganizing and cleaning the internals all around the place.
+
+ SMPI
+ * Remove old default barrier/bcast buggy algorithms (see #18407)
+ * Various bugfixes to handle more codes
+
+ XBT
+ * Kill the setset data container: MC don't use it anymore.
+ * Kill the queue data container: it made more sense with GRAS.
+ * Kill the xbt_peer_t data type: it's useless without GRAS.
+
+ JAVA:
+ * Remove the ability to write internal plugins in Java.
+ It may be reintroduced once the ongoing cleanup is done.

+SimGrid (3.12) stable; urgency=low
+
+ The Facelift Release.

+ * Move headers around to sort them out on installed systems:
+ - instr/instr.h -> simgrid/instr.h
+ - instr/jedule/* -> simgrid/jedule
+ - simdag/datatypes.h was removed
+ - simdag/simdag.h -> simgrid/simdag.h
+ - msg/datatypes.h was removed
