+- Actor: Merge signals on_migration_start/end into on_host_change
+- Actor: Rename migrate() into set_host()
+- Disk: Allow users to get the read and write nominal bandwidth values
+- Exec: Implement wait_for(timeout)
+- Io: Implement wait_for(timeout)
+
+XML:
+- Parse errors now raise a simgrid::ParseError that you may want to catch.
+
+Kernel:
+- In simgrid::kernel::resource::Model, the methods next_occuring_event*() have
+ been renamed to fix a spelling error. As usual, the previous definitions are
+ kept with a deprecation warning. However, to avoid runtime errors, it is now
+ forbidden to override these deprecated methods in a derived class. Please use
+ the new names immediately if you need to override them.
+
+XBT:
+- Remove unused parameter 'free_ctn' for xbt_dict_set() and xbt_dict_set_ext().
+- Drop unused functions for dicts and dynars: xbt_dict_cursor_get_elm,
+ xbt_dict_get, xbt_dict_get_elm, xbt_dict_get_ext, xbt_dict_get_key,
+ xbt_dict_remove, xbt_dict_reset, xbt_dynar_compare, xbt_dynar_dump,
+ xbt_dynar_foreach_ptr, xbt_dynar_free_data, xbt_dynar_free_voidp,
+ xbt_dynar_init, xbt_dynar_insert_at_as, xbt_dynar_merge,
+ xbt_dynar_remove_n_at, xbt_dynar_replace, xbt_dynar_search, xbt_dynar_set.
+- New module: random, providing classical random numbers generators.
+
+SMPI:
+- New option : "smpi/auto-shared-malloc-thresh" which sets a value for
+ allocations' size above which they are considered "shared" by default (as if
+ they were performed through SMPI_SHARED_MALLOC macros).
+ Default = 0 = disabled feature.
+ Note : malloc, calloc and free are now overriden by smpicc/cxx by default.
+ This can cause some troubles if codes are already overriding these. If this
+ is the case, defining SMPI_NO_OVERRIDE_MALLOC in the compilation flags can
+ help, but will make this feature unusable.
+- Input check is now performed much more consistently and outputs precise
+ warnings for each error found
+- New supported calls : MPI_File_set_view, MPI_File_get_view
+- MPI I/O now only supports disks, as storage is discontinued.
+- MPI I/O allows opening files without specifying absolute path
+- Note : SMPI configuration options are now initialized by smpi_init_options()
+ call, which should be called if SMPI is not being used through smpirun.

+SimGrid (3.24) October 9. 2019
+
+The Clean Disk Release.
+
+S4U:
+ - Introduce a s4u::Disk interface to manage the newly introduced <disk>
+ tag. s4u::Disk is called to supplant s4u::Storage in a near future. It
+ thus becomes the default resource to execute I/O operations. Examples
+ and the file system plugin have been modified to use disks instead of
+ storage elements. Storage can still be used but is doomed to disappear.
+ Users are thus adviced to update their simulators accordingly.
