Point File In TOP - .xyz, .obj, .exr, .FITS/.FIT, .pts, .ply files supported. It will create a square multi-RGBA buffer with pixel format 32-bit floats. Generally it can be set up as one pixel for each point, and the pixels that are unused contain NAN (a special value called Not-A-Number).

Point File Select TOP - This new TOP can select channels from a Point File In TOP, useful when multiple buffers exist.

TOP Viewer modes have been extended.

TDJSON updated and bugs fixed.

OP Class.pars(pattern) now supports legacy parameter names.

textTOP_Class / textSOP_Class - Improvements

SOP Class maximized .min .max .size members
