Which of the information on this site isn't updated? What exactly are you interested in? D3Planner has a bunch of public data on up-to-date datamined info accessible, but it really depends on what you need. The max stats on the D3Maxstats websites are still fine though, none of that hasn't changed to my knowledge.
For that I'd recommend D3planner:
