Since the 17 Jun 2021 nightlies here https://nightlies.chaosgroup.com/, you can:
Use PRT data with the preview auto reduction, preview coloring by velocity, age, etc, slice preview
Use Time Bend controls to change the playback speed or animate the playback of PRTs
Plug the PRT particles into a particle texture - it does not support the PRT Reader node so far
PRT import in Maya was not possible so far - no PRT Reader there yet
Flip Y/Z axes of the PRT particles
Cache info box with particle numbers and supported channels
The standalone preview can show PRT as well and now you can associate it with PRT caches under Windows as well
The cache converter can convert from PRT to AUR and VDB
