Yet another release focusing on internal modifications that will allow next developments.

[0.13.1] 2026-04-21

  • [BREAKING] when loading a powergrid from pypowsybl with "use_buses_for_sub" tagged
    and disconnected element on the grid will now raise a RuntimeError. Before there were
    some "automatic" bahaviour to try to find a possible bus which could lead to
    error afterwards.
  • [BREAKING] adding a more precise information about linear solvers. The "refactor" timings
    are now also available in solver.get_timers_jacobian() which now returns a tuple of size 10
  • [FIXED] an issue where disconnected powerlines could be tagged as "fakely connected"
  • [FIXED] some issues when loading a grid from pypowsybl in case of disconnected elements.
  • [FIXED] remove the undefined behaviour while maintaining compile time check to prevent
    wrong conversion from different bus labelling.
  • [IMPROVED] the CI to allow automatic push on pypi on new version tag (introduced in version 0.12.0)
  • [IMPROVED] reduce code duplication between ContingencyAnalysis and TimeSerie (cpp side)
  • [IMPROVED] handling of branches disconnected at only one side: less code duplication and
    it should be working with TimeSeries and ContingencyAnalysis
  • [IMPROVED] speed (DC mode): avoid the systematic call to "refactor" when Ybus is not changed
    when using DC approximation.
  • [IMPROVED] simplify the future integration of other linear solvers and the logic when linear_solvers
    are called by decoupling "refactor" steps from "solve" steps (they used to be all under the same
    "solve" method).
