Blender version support (4.3)
Version 1.68 update notes;
Physics / Proxies (HHP):

This addon has an auto update feature. But you can always click the check for update button and update it yourself if you don't want to wait for the auto update and you want the features now. Be sure to restart Blender after the update completes (It usually takes 2 seconds or less)
