Although there haven't been any major announcements, from daily anecdotal evidence I can confirm it's still a major factor to get you into the front pages.
I'd say the major changes since deprecating PageRank in practice are 1. Much higher dependence on CTR and bounce rate once you start showing up in the SERPs 2. Much higher influence of a notion of "trust" on links (not just the quantity, but mainly the quality counts now, too much quantity without quality can actually hurt) 3. PageRank much more disconnected from domain level. A few years ago, you could rank with pretty much anything if your DomainPop was high enough. By now, Google got much smarter about different folders that don't have anything to do with what it's ranking your main site for and it's harder to get them ranking. On the bright side, they also got smarter about the negative SEO influence of subdomains or domain changeovers, which won't cost you as dearly.
So TL;DR: PageRank still exists, but it's been reduced to an input vector.
