I don't have a specific date, but Google has changed its crawling method. I think Google is now ignoring the "static" version (before the javascript runs) and just evaluates the "final" (rendered) version.

For articles, I embed resized images that link directly to full-size versions. When the DOM is ready, javascript replaces those links with links to optimized gallery pages. Around July-August, full version images started dropping from Google Images results.

Funny thing is, some of them are now appearing under a different website that iframes my pages with sandbox (javascript never runs, so Google crawls full-size image links)

I've switched from replacing links to attaching window.open events and Google started to crawl & include full-size versions.

this is very interesting to see google is handling javascript.

is this a generic technique to handle headless browsers or something specific to your application?

Not generic, attaching onclick event doesn't change 'right click and open', so I was changing the actual link.

I was right. They've just announced the "rendering-based indexing."

I wonder if this might lead to a more sophisticated version of the "Page Layout Algorithm" (a.k.a. the "Top-Heavy Algorithm") that would look at total page clutter, not just at ads above the fold?

As I see it, they are targeting too many above-the-fold ads, not sites with pages containing heavy number of ad units, otherwise, thousands of sites will fall off the roof.

Either way, they want access to your script files and will downgrade you otherwise.

Good to hear.

Hopefully that means those sites with the annoying css-based pop-over ads that take up nearly the full size of the screen will start to loose rankings.
