TTN V3 stack not supported

[jerryneedell]

This library is not compatible wit The Things Network v3 stack. Since TTN has fully migrated to v3, this library is not longer able to communicate with TTN.

This was also raised in.

What is the alternative? Is there another library that already supports TTN v3? Is there a plan to update this library to v3?
I am desperately trying to figure out which pieces I need to build a Rasberry Pi TTN node that sends some data to a TTN gateway. Lots of the tutorials are confusing and others are out of date. TinyLoRa looked promising, but if I understand this issue correctly it is also out of date? Any help appreciated.
