v5.0.0

• A constant=True term is reused while its arguments keep the same values, checked
  against a copy taken when it was built, instead of hashed, so array arguments such as
  material.C or an array rho are cached too, and an in-place write is seen.
  Elastic (including Rayleigh damping), Thermal and HyperElastic's mass declare
  every solution-independent term constant.
• A constant=True term refuses a bound-method operator, and a list, dict, set or
  identity-compared object argument (breaking).
• Term.Scaled(coef, slots=None) returns a copy multiplied by coef, outside the
  cache, so Rayleigh damping reuses the stiffness and mass integrations.
• The term cache is dropped on a mesh notification, and a simulation observes a mesh
  assigned after construction.
• Simu.Add_terms, Simu.Terms_Init and Term.Set are removed (breaking): a
  simulation is extended by subclassing it and composing Get_terms, and a value that
  changes between steps is a parameter of that subclass (see
  examples/CardiacElastoDynamics/utils.py). A simulation saved with added terms
  reloads without them.
• Python 3.10 to 3.14 are supported: 3.9, end-of-life since October 2025, is dropped
  (breaking) and 3.14 is added. Annotations use X | Y instead of Union and
  Optional.
• Docs: the gallery keeps its interactive scenes. docs/requirements.txt requires
  trame-vtk>=2.11.15 and pyvista>=0.49, and the build fails instead of silently
  falling back to static images. The how-to's RigidContact declares itself nonlinear.
• CREDITS.md credits JAX and mpi4py.
• Contributors: make format and make lint run black, ruff and mdformat at the
  versions pinned in the lint extra; CI runs make lint. All tracked Markdown is
  formatted with mdformat, wrapped at 88 columns.
