Searching for a rule engine with fuzzy logic abilities

I am looking for a rule engine with fuzzy logic abilities. I wanted to use Jess

but unfortunately it's fuzzy logic plugin is out of date, it's not supported any more and I was unable to download it anywhere. Is there any similar modern software with this abilities? I know about CLIPS and FuzzyCLIPS but 开发者_开发问答seemed to look old and useless nowadays, isn't it?
