Looks like we're getting a revamp here.
I don't think so. Several days ago, Mikolas said in his instastory that changes in the polished version are so marginal (literally only removed three or four problematic words), that he doesn't think it needs to be released as a new version. But who knows, I had no time to stalk instagram since then, perhaps something changed.
BTW, I also watched one truly bizarre live-streamed interview with him on Instagram of local socialite/c-list celebrity Nikol Moravcová. It was one hour long, but sadly not very informative, because this woman tends to be constantly talking about herself, drinking champagne and reading pointless comments of her followers instead of asking questions. However, I was surprised when Mikolas said that Lie To Me (original, released version) was not even recorded in studio, but in his living room, and the music video cost him only 54 000 CZK (cca 2 100 Euro). One of his previous clips - Free - was even cheaper (37 000 CZK/1 400 Euro). Both videos look much more expensive, imo.
