Thanks.
Ahhh - I think I didn’t run the right update command…
I now have 6.8.1 installed.
Unfortunately, the changes I need are in v3.x
The fork you referenced above mentions that the official espressif32 has a “lack of ongoing development” and in turn referenced a thread Documentation - Update supported IDEs and general improvements by lucasssvaz · Pull Request #8606 · espressif/arduino-esp32 · GitHub that seems to suggest that espressif is not very interested in supporting the PIO/VS IDE.
-
Any sense on when, if ever, mainline will support v3.x?
-
Is the fork referenced above considered “stable” and “well-supported” by the PIO community?
-
Is the general sense of the community that one should move to a fork like the one listed above or should one generally stick with the official espressif version unless one really needs the latest 3.x features?
Even if the answer isn’t totally straightforward, it would be helpful to get some pointers so I can at least make the right decision for my situation 
And I don’t want to be stuck on a “dead-end”, “unsupported” path
