I think jQuery is amazing, but one thing that I've found over the years is that the real killer for it was CSS animations becoming simpler to use and more widespread in terms of support.
The final thing I used to reach for jQuery for was animation support, but that need is by and large gone now. AJAX/JSONP is good there, but to be honest it's not something that needs a wrapper these days.
Glad to see the library is still updated, though - for sites that might not have a budget to upgrade, knowing it's still got support must be nice.
CSS animations are a pain-inducing non-starter for thousands of recurring use cases.
Example: Using Javascript to SHOW a modal, but then relying applying addClass('animate') using CSS animations to transition that modal (eg: bottom of screen to center, while fading in) are nearly impossible without tons of hackery. The animations do not render.
