Build releases stability/ Is 4.15 safe???

Okay, if I use my sense I would guess it would be wise for me to use the previous version last major which is the most stable(exp. last build of 4.14). And note, this one tried to speed up compile times( thinks about what i just said while continue writing this lol) I 'm running into a ton of compile related isssues. As far as blueprintnative having issues, and compiling code that doesn’t update on editor unless , and… writing correct code which doesn’t work. Idk if I didn’t the editor last night on the second error(think i went to sleep and just returned) after crash which restarted engine started to work again… Either these are thing I have to work around or go back a build? Any suggestions fellow coders?

I have a i76800k so I’m super beef cheese cake over here
