I have "Delete originals" checked, but the original files still exists after upload and optimization. My assumption was uploadfiles would be optimized and then deleted while files already uploaded would be deleted only after manual optimization. Is this correct?
Also, I have current versions of jpegtran and gifsicle from homebrew and am still seeing update availabe notice.
