 Changelog
 ---------
 
+4.5.31 (2026-04-13)
+~~~~~~~~~~~~~~~~~~~
+
+Added
+^^^^^
+
+* Added :class:`~isaaclab.envs.mdp.randomize_rigid_body_inertia` event term for
+  randomizing body inertia tensors independently of mass. Supports diagonal-only
+  (Ixx, Iyy, Izz) and full 3x3 modes.
+
+Changed
+^^^^^^^
+
+* Split :class:`~isaaclab.envs.mdp.randomize_rigid_body_material` into
+  backend-specific implementations. PhysX uses bucket-based 3-tuple materials via the
+  tensor API; Newton samples friction and restitution continuously per shape via
+  view-level attribute bindings.
+* Converted ``randomize_rigid_body_com`` from a plain function to a
+  :class:`~isaaclab.managers.ManagerTermBase` class with repeatable randomization
+  from cached defaults. Newton passes position-only (vec3); PhysX passes full pose
+  (pos + quat).
+* Converted ``randomize_rigid_body_collider_offsets`` from a plain function to a
+  :class:`~isaaclab.managers.ManagerTermBase` class with backend-specific
+  implementations. PhysX uses rest/contact offsets directly; Newton maps them to
+  ``shape_margin`` and ``shape_gap``.
+

+  :meth:`~isaaclab_physx.assets.RigidObjectCollection.set_material_properties_mask`
+  methods for setting collision shape material properties (friction, restitution).
+  These methods follow the standard ``_index``/``_mask`` pattern, providing a unified
+  API across PhysX and Newton backends.
