MeshedVR just posted this on Discord:
"I was trying get a 2.X progress update posted on Patreon the last week or so, but I was unable to complete the video content I wanted to put in the update in time. Unfortunately I have to go out of town for several days on a family matter so the progress update won't come until next week. You may be able to figure some of what the update is about by reading my comments the last few weeks. I talked a lot about the addon system we are using internally that will also be distributed to the community for making custom content. This addon system is now fully functional and is able to send content to the runtime application. What is even better is how well that addon content loads into the runtime application. It will be night and day comparing load times between 1.X and 2.X. That is all I have time to report on until I get back to complete the update. I won't be on here for several days. Thank you all for your support."
Sounds like we will get the new addon system with the next 2.x alpha
