-SimGrid (3.10) NOT RELEASED; urgency=low
+SimGrid (3.11) NOT RELEASED; urgency=low
+
+ TENTATIVE RELEASE GOALS for 3.11:
+ * Switch to tesh.pl, and kill the now unused parts of xbt that seem fragile
+ * Clean up CMake files (may need a full rewrite).
+   Non exhaustive list of subgoals:
+   - Use genuine cmake mechanisms and variables when available,
+     instead of reinventing the wheel.
+   - Correctly determine system and architecture (e.g. x32).
+   - Correctly determine compiler type and version (e.g. clang).
+   - Correctly set compiler flags according to compiler type and version.
+   - Correctly set compiler flags for C++, Java, and Fortran compilers too.
+   - Use git to generate the dist archive.  Either use git-archive to
+     generate the tarball, or keep using cmake -E tar, but use git-ls-files
+     to get the list of files to pack.
+
+ The Class Release.
+
+ Tools:
+ * Normalizing pointers addresses tool for better diff between logs
+
+ Examples:
+ * Add cloud examples using new VMs
+   - examples/msg/cloud/two_tasks_vm.tesh
+   - examples/msg/cloud/simple_vm.tesh
+   - examples/java/cloud/cloud.tesh
+   - examples/java/cloud/migration/migration.tesh

 
 

- XBT:
- * Our own implementation of getline is renamed xbt_getline, and gets
-   used even if the OS provide a getline(). This should reduce the
-   configuration complexity by using the same code on all platforms.
- * new xbt_cfg_elm_boolean type
- * Allow to disable SimGrid cleanups at exit from command line option.
-   There are situations where one may want a simulation to end with an exit.
-   Unfortunately, calling exit may cause SimGrid to segfault, which is quite
-   annoying when scripting around the simulator. Adding a
-   --cfg=clean_atexit:yes allows to circumvent this issue.
+ MSG:
+ * Add virtual machine
+   - creation of a VM on a PM
+   - migration of a VM from a PM to another PM
+
+ SIMIX:
+ * Protect context stacks against stack overflow. The number of protected memory
+   pages allocated on the top of each stack (1 by default) can be configured
+   with the new command line option --cfg=contexts/guard_size:<value>.
+ * Simcalls are now generated by a python script that
+   - generates files included by SimGrid
+   - checks that all the functions exist, and proposes prototypes
+ * Clean simcalls
+   - remove sem_destroy, file_set_data, comm_destroy, vm_set_state,
+     host_set_data, host_get_data
+
+ SURF:
+ * Translate surf models from C to C++
+   - Generic classes for all models: Model, Resource, Action
+   - A generic interface for each kind of model (cpu, network, storage
+     workstation, workstationvm)
+   - C bindings
+ * Translate surf routings from C to C++
+ * Add callbacks using sigc++ or boost::signals2
+   - Add callback functions for resource creation/destruction
+   - Add callback functions for action state change
+   - Handle Energy as a plugin
+ * Replace swag by boost::intrusive
+ * Add new routing model for torus clusters
+ * More documentation
+
+ SMPI:
+ * hostfiles support host:nb_processes construct to deploy several processes on
+   one node
+ * Collective communication algorithms should not crash if used with
+   improper number of nodes and report the error.
+
+ Java:
+ * New cmake option, enable_lib_in_jar, to control whether native libraries are
+   copied into simgrid.jar or not (ON by default).  Use this option if you want
+   to reduce the size of the installed simgrid.jar, *and* the native libraries
+   are kept installed elsewhere.
+
+ Build System:
+ * Supernovae build mode is definitively removed. It was used to improve
+   inlining and inter-module optimizations. It is nowadays superseded by
+   link-time optimizations commonly available in compilers.
+ * Update ns-3 find lib. Bindings for ns-3 should work again now.
+ * Add boost dependency for surf++
