node_a to be the "world node" rather than node_b. This diverges from how Godot Physics behaves, but matches how Bullet behaves in Godot 3, and yields more intuitive outcomes for the 6DOF joints.Generic6DOFJoint3D and ConeTwistJointImpl3D, as well as their substitute joints, to use pyramid-shaped angular limits instead of cone-shaped limits, to better match Godot Physics.equilibrium_point properties for Generic6DOFJoint3D and JoltGeneric6DOFJoint3D, to match the direction of the angular limits.equilibrium_point properties for Generic6DOFJoint3D and JoltGeneric6DOFJoint3D, from ZXY to XYZ, to match the rotation order of the angular limits.JoltSliderJoint3D and JoltGeneric6DOFJoint3D.RigidBody3D frozen with FREEZE_MODE_KINEMATIC to report contacts/collisions with other kinematic/static bodies, at a potentially heavy performance/memory cost.HeightMapShape3D.HeightMapShape3D.HeightMapShape3D not using back-face collision.max_contacts_reported property to a lower value.Generic6DOFJoint3D and JoltGeneric6DOFJoint3D would yield odd limit shapes when using both linear and angular asymmetrical limits.Generic6DOFJoint3D and JoltGeneric6DOFJoint3D would be moved when using asymmetrical limits.RigidBody3D with locked axes colliding with a StaticBody3D (or another frozen RigidBody3D using FREEZE_MODE_STATIC) would result in NaNs.HingeJoint3D and JoltHingeJoint3D would sometimes dull forces applied to either of its bodies when at either of its limits.Info.plist missing the MinimumOSVersion key.This release only supports Godot 4.2 (including 4.2.x).

HeightMapShape3D to always use back-face collision, to match Godot Physics.move_and_slide will respect such velocities.RigidBody3D.body_set_force_integration_callback could be called even when the body is sleeping.This release supports Godot 4.1.

gravity_point_unit_distance for Area3D to result in a constant gravity when set to zero, rather than resulting in a zero gravity, to match Godot Physics.hit_from_inside parameter report a zero normal when hitting a convex shape from inside, to match Godot Physics.space_get_contacts method of PhysicsServer3D (and thus also the "Visible Collision Shapes" debug rendering) to no longer include contacts generated by overlaps with Area3D.Parameter "body" is null would be emitted after freeing certain bodies while they were in contact with a CharacterBody3D.RigidBody3D could sometimes still be moved by another RigidBody3D despite the first body not having the second body in its collision mask.This is the second release candidate for version 0.10.0, and assuming no major bugs/regressions are found is likely to become 0.10.0-stable.

ConvexPolygonShape3D to no longer emit errors about failing to build the shape when adding one to the scene tree with 0 points.Generic6DOFJoint and JoltGeneric6DOFJoint would lock up any axis that used a spring stiffness/frequency of 0.ConcavePolygonShape3D.This release supports Godot 4.1.

apply_force and apply_impulse to be applied at an offset relative to the body's origin rather than at an offset relative to the body's center-of-mass, to match Godot Physics.Area3D to behave like they do in Godot Physics, allowing for asymmetrical setups, where overlaps are only reported if the mask of an Area3D contains the layer of the overlapping object.body_set_force_integration_callback method of PhysicsServer3D to behave like it does with Godot Physics, where omitting the binding of userdata requires that the callback also doesn't take any userdata. It also will no longer be called when the body is sleeping.JoltPhysicsServer3D as an actual singleton, which makes Jolt-specific server methods (e.g. pin_joint_get_applied_force) easier to deal with from dynamic scripting languages like GDScript.space_dump_debug_snapshot to JoltPhysicsServer3D, for dumping a binary debug snapshot of a particular physics space.dump_debug_snapshots to JoltPhysicsServer3D, for dumping binary debug snapshots of all currently active physics spaces.move_and_slide, where under certain conditions you could get stuck on internal edges of a ConcavePolygonShape3D if the floor was within 5-ish degrees of floor_max_angle.move_and_slide, where under certain conditions, while using a BoxShape3D or CylinderShape3D shape, you could get stuck on internal edges of a ConcavePolygonShape3D.ConvexPolygonShape3D could yield a flipped contact normal.Area3D with monitoring disabled wouldn't emit any entered events for already overlapping bodies once monitoring was enabled.RigidBody3D attached to a joint would shift its transform relative to the joint.total_gravity property on PhysicsDirectBodyState3D would always return a zero vector for kinematic bodies.Area3D detecting overlaps slightly outside of its collision shapes.This is the second release candidate for version 0.8.0, and assuming no major bugs/regressions are found is likely to become 0.8.0-stable.

JoltDebugGeometry3D node for all distributed builds. If you still need it, build from source using the *-development or *-debug configurations.ConcavePolygonShape3D if its hit_back_faces parameter is set to false, regardless of what the backface_collision property of the ConcavePolygonShape3D is set to.HeightMapShape3D to match Godot Physics.HingeJoint3D (or JoltHingeJoint3D) would rotate counter-clockwise instead of clockwise.ConcavePolygonShape3D that had backface_collision enabled, you would sometimes end up with a flipped normal.CharacterBody3D using move_and_slide could sometimes get stuck when sliding along a wall.RigidBody3D with locked axes to a joint could result in NaN velocities/position and subsequently a lot of random errors being emitted from within Godot.
