-SimGrid (3.29.1) NOT RELEASED YET (v3.30 expected December 21. 2021, 15:59 UTC)
+SimGrid (3.30) January 30. 2022.
+
+The Sunday Bloody Sunday release.
Main user-visible changes:
- The SimDag API for the simulation of the scheduling of Directed Acyclic
- Introduce on_X_cb() functions for all signals, to attach a new
callback to the signal X. The signal variables are now hidden and
only these functions should be used.
- Rationale: this enables the usual deprecation schema where functions
+ Rationale: this enables the usual deprecation scheme where functions
remain for 4 releases if we need to modify the signals, while the
current code with the signal variables directly visible prevents any
smooth transition.
- New function: Engine::run_until(date), to split the simulation.
- New signal: Activity::on_veto, to detect when an activity fails to start.
- - Signal change: Comm::on_start(Comm&, bool) has been replaced by
- Comm::on_send and Comm::recv. These two signals respectively correspond to
- when the sending or receiving side of a Comm is ready. They are raised at
- the same locations as the former Comm::on_start signal.

- New function: Engine::track_vetoed_activities() to interrupt run()
when an activity fails to start, and to keep track of such activities.
Please see the corresponding example for more info.
- New functions: s4u::Comm::{sendto_init, set_source, set_destination} to enable
- the use of vetoers with direct host-to-host communications. Both source and
+ the use of vetoers with direct host-to-host communications. Both source and
destination have to set for a comm to start. Each call to these setters check
- if all vetos are satistied. When it is the case, the comm starts. A use case of
- these functions is given in examples/cpp/dag-scheduling.

- New functions: {Exec, Io}::update_priority allow you to modify the priority of

SMPI:
- Dynamic costs for MPI operations: New API to allow users to dynamically
change injected costs for MPI_Recv, MPI_Send and MPI_Isend operations.
Alternative for smpi/or, smpi/os and smpi/ois configuration options.
+ - Fix some issues with the replay mechanism.
XBT:
- Function xbt::Extendable::get_data() is now templated with the type of the
