The smoke and fluid solvers now support sinks that are defined by relationships. The previous ability to have a scalar field named "sink" in fluid objects no longer will work as it is overwritten by the sink field defined by the relationships.

Also of note is that sink fields are "negative is inside the sink" now - the previous method used the exterior to be inside.

The Sink from Objects fluid tool should now work.

The smoke and fluid objects now default to having a bounding box geometry visualize the space they are acting in. Note that this will be imported by Object Merge or DOP Import Object, so old .hip files may have to turn off the Bounding Box option of the Surface and Density guide geometry to return to old behaviour.

When copying and pasting parameter expressions, Houdini now automatically sets the pasted parameter's expression language to match the copied parameter's expression language.
