Version 4.2.0 Changelog from 4.1.0 is below. Also available on batsim.rtfd.io Added ~~~~~ - New :ref:`usage_trace_replay_profile` profile, that enables the replay of usage traces over time. This is especially helpful to replay applications from their power consumption traces. Fixed ~~~~~ - Using ``simgrid::s4u::Mailbox::put_async`` led to invalid memory management of ``simgrid::s4u::Comm`` objects. This sometimes resulted in segmentation faults, especially when using SimGrid 3.34.0. Batsim no longer calls ``put_async``. - Batsim's memory consumption increased over time due to lazy/bad ZeroMQ buffers management — cf. `issue 2 (framagit) <https://framagit.org/batsim/batsim/-/issues/2>`_.
