Taz 5 and Marlin 2.1 firmware

Is anyone using Marlin 2.1 on their Taz 5?

I noticed in the configuration releases for Marlin that there is an example configuration file for a Taz 4 and as I understand it the two machines are pretty similar?

oh and I also just found some Lulbot official hex and config files for Marlin here: Index of /software/Marlin/
