RadPerf testing tool not avaliable

Good morning everyone, Is there any possibility to get RadPerf program so we can test it against our new freeradius server? I've looked in the official page, but the current form to get this tool its not working. It would be really good if we can get access to it, so we won't need to create a new one from scratch using radclient. And another question, for the ones that have used it. Is the tool compatible with the new 3.x branch or only with the 2.x.x and below? Thanks for your time, Alex
