Safari cleaned up their act in the last year: http://caniuse.com/ http://caniuse.com/ So far they're third going by the caniuse score, which is based on the features developers can use. Previously it last place. I don't think it was the developer backlash that forced Apple to start releasing TP previews of Safari and progressing features. I was likely more of a gap between major versions (Safari 9.x vs 10.x)
