That's not unexpected, with the popularity more companies apply - even some who would have never done it in past. So, I'd assume applications will continue to grow and acceptance rate should be going down. If the acceptance rate stays the same, I guess YC is lowering the bar. This likely happened already given the top ranking post from a YC member saying that acceptance is same still even though many more apply.
