Nothing new here.
By happenstance I recently removed a clutch of pages, so I'm getting a lot of 410s anyway. No unusual 404 activity lately: that seems to have come a month or two back with a flurry of garbage requests. That is: not misreading of links or bad parameters, but the kind you get when the cat walks across the keyboard-- or the search engine is checking for soft 404s.
By unrelated happenstance I also added a whole slew of (non-indexed but crawlable) pages last month. So this too may have triggered some robotic investigation.
