There are screenshots (though not animations!) in the announcement for darktable 3.0 at https://discuss.pixls.us/t/darktable-3-0/15384 https://discuss.pixls.us/t/darktable-3-0/15384. The images do really help to get a sense of the new features. It's a good point that it would be great to have such images accompanying the release announcement on the main darktable site.
