Hi, I did a hack that solves the most urgent issue. The problem is that images changed by media library editor gets new filenames – any old references to the thumbnail will therefore point to the unedited version. This hack will rename the edited image to the original (overwriting it!). Only affects intermediate size, e.g. 150×150 thumbnails, at the moment.

/**
 * Edited images using media library image editor gets new filenames, so
 * will not automatically be used by posts where they have already been inserted.
 * This filter detects those re-crops and changes the name back to the original
 * Caution: Will overwrite original thumbnail. Only affects "intermediate size".

function overwrite_recropped_thumbnail($resized_file) {
	// Remove timestamp added to re-cropped images. TODO improve regex to avoid
	// accidental path changes
	$new_path = preg_replace( '/-e([0-9]+)-/', '-', $resized_file, -1, $count );
	if($count>0) { // The file path had the timestamp, move back to original name
		rename($resized_file, $new_path);
		return $new_path;
	} else { // do nothing
		return $resized_file;
	}
}
add_filter('image_make_intermediate_size', 'overwrite_recropped_thumbnail',10);
