I can't find my really old version of imgmin to compare but I just ran an image through it and it set the after quality to 65 as the "perfect" quality even though the image is full of jpeg artifacts normally imgmin has always given me images that I can't tell the difference between at 100% zoom only if I zoom in waymore than that can I begin to notice it.

imgmin's "optimzied" file that it says is nearly identical to the original image when it clearly is not as there is a crapton of compression artifacts throughout the image. 2016-10-08-000043- optimized original file quailty was 90 non-progresive non optimized even huffman optimied via jpegtran 2016-10-08-000043

thanks for the feedback and the examples. for your usecase you may prefer more conservative settings -- have you tried imgmin's commandline options? -- see imgmin --help and look at --conservative, --very-conservative and --error-threshold N in that order to see if you can find options that work you.

I didn't know it had any sort of options before it had always just worked I guess it's something to do with anime images I have genrally just used imgmin for all jpegs I have and never thought anything of it to save space.
