Yes, there is a difference, comparing 4.3.4.1 and 4.4.0.0. The file size was what alerted me: it has been reduced from enormous to a reasonable size. For example, the latest community magazine comes out as a 169Mb PDF with 4.3.4.1 and just 30Mb with 4.4.0.0. Every example that I've looked at shows that pictures are either stored in their original format, or converted to PNG (if not already PNG) and made larger. The difference is that 4.3.4.1 seems to do it with most images, whereas 4.4.0.0 with very few. When a specific image is converted by both 4.3.4.1 and 4.4.0.0, the resulting file is identical, which suggests that the algorithm has not changed; only the decision whether or not to convert has changed. As for a pattern, I've not been able to find one. As mentioned before, there seems to be no pattern as to whether the images are linked or embedded, large or small, resized or not. It seems random. I'm sure it's not random, but still, I find it crazy to modify any of the images especially as they are always made larger (why take a lossless PNG image and make it into a bigger PNG?).
