Yes, the version on Aminet is the most recent, and the last.
I wouldn't bother with rtgpip either - it's a great idea but only ever worked on P96. If you have a BVision I guess you use cybergraphx, so it won't work for you.
But at least you can still use rtgmaster stuff. It will eventually stop working with more modern graphics cards on Amiga PCI, AmigaONE and Pegasos because of endian problems.
