+S4U:
+- 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
+
+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

+
+XBT:
+- Remove unused parameter 'free_ctn' for xbt_dict_set() and xbt_dict_set_ext().
+- New module: random, providing classical random numbers generators.

+SimGrid (3.24) October 9. 2019
+
+The Clean Disk Release.
S4U:
- Introduce a s4u::Disk interface to manage the newly introduced <disk>
MPI_C_COMPILER, MPI_CXX_COMPILER, MPI_Fortran_COMPILER variables.
- Add support for MPI Errhandlers in Comm, File or Win. Default errhandler is now
MPI_ERRORS_ARE_FATAL, so codes which were sending warnings may start failing.
- - trace-call-location can now be used with TI traces, and replayed.
+ - trace-call-location can be used with TI traces, and replayed, and is compatible
+ with smpi/comp-adjustment-file.
+ - sleep events are now correctly traced/replayed.
- Default for trace-call-location is now to use file names and not full paths.
- To revert to previous behaviour (in case of collision of filenames), option
+ To revert to previous behavior (in case of collision of filenames), option
"smpi/trace-call-use-absolute-path" can be set to yes.
Model-Checker:
- MPI calls now MC_assert() that no MPI_ERR_* code is returned.
This is useful to check for MPI compliance.
+Documentation:
+ - New section on plugins: how to define a new one, and existing ones.
+
XBT:
- xbt_mutex_t and xbt_cond_t are now marked as deprecated, a new C interface
on S4U is already available to replace them by sg_mutex_t and sg_cond_t.
only three attributes (id, read_bw, and write_bw). All the other information
that was declared with the storage related tags now has to be expressed as
properties. An example of platform using this new tag is available at

+
+tesh:
+ - 'expect signal' can now accept more than one potential signal.
Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
- FG#28: add sg_actor_self (and other wrappers on this_actor methods)
- FG!16: Fix the ns-3 bindings when several flows are simultaneously finishing
- FG!17: ns-3: unblock the right number of communications + others issues
- FG!18: Improving the performance of the ns-3 bindings

it right now (subsequent read will peek the buffer)

- In composed data description (struct, ref and so on), stop foolness of
keeping the subtype's ID, but store the type itself. This keeps sets out
of the critical path, which is good since they rely on dynar and
- dictionnaries. The only loose of that is that we cannot detect the
+ dictionaries. The only loose of that is that we cannot detect the
redeclaration of a structure/union with another content (but I'm not sure
the code detected well this error before anyway). We still can detect
the redefinition discrepancy for the other types.
