I downloaded the latest version and it requires p455w0rd's Library which has not been updated since September. Is there a way to get this download?

Sorry about that! You can contact me on discord for now till its approved on CF

I am dealing probably with the same issue - mod AE2 wireless terminals is missing last library 2.0.36 (last updated library is 2.0.35)

its just been approved on Curse https://minecraft.curseforge.com/projects/p455w0rds-library/files/2651697 Sorry!
