Check the Release notes for Alpha 5.4. There are numerous fixes to your reported bugs/defects. Also there is a new form of attribute component swizzling where instead of Color(1) Color(0) Color(2) you can put Color.grb, or P.xy or for any attribute MyAttrib.i0123. And a work-in-progress Line Smooth POP to blur line strip points with adjacent points, and more.
February 14, 2025: Here is the full package: TD Alpha POPs 5.4, a hotfix from 5.3 on February 11.
Amazing, Greg! Excited about glsl style swizzling!
It appears there’s minor licensing bug: my normal pro license was not accepted (I have an Official Parallel Build 12120 that’s working just fine and just purchased maintenance). Only when I released license from the Official Build that I could generate a key in the Experimental again.
Cheers!
+1 @greg GLSL style swizzling is fantastic! 
Yes adding glsl-like swizzling was a great idea!

regarding the swizzling can you explain MyAttrib.i0123 a bit more? what does the i indicate, component index?
Good question. I wish it was simpler. But in the land of python parsing, correct us if we’re wrong, you cannot have a digit following an AttributeName.___ so we chose i for index, and what follows are the general component indexes that cover everything else: 0, 1, 2 or 3 in any order (the swizzle). We have .xyz for 3D coordinates (and w), and we have .rgba for color components, but for all other data types, say if the 3 components are year/month/day, or latitude/longitude/radius, .i0123 are general attribute component designations that you can use for anything. So MyPolarAttribute.i2 is the radius in this example. MyPolarAttribute.i10 is longitude/latitude. And that is equivalent to MyPolarAttribute(1,0)
Comments welcome!
somewhat explained in “Selecting Components of Attributes and Swizzling” on the Learning About POPs page.
Slight bug fixes in Alpha 5.3 (nodes in network mis-snapping) brings us a full Alpha 5.4 including the macOS builds:
Again, Release notes for Alpha 5.4
