[Plugin: WP Security Scan] What’s with the empty updates?

I’ve noticed that wp-security-scan is updated more frequently than any other plugin I have. This is good, since it’s under active development. The weird thing: Out of curiosity, I’ve started downloading it instead of using the automatic updater, so taht I can compare what’s changed, and in at least two cases the ONLY change from the previous version is the version number itself.

For example: 2.2.56.59 and 2.2.56.61 are absolutely identical except for the version number listed in readme.txt and securityscan.php.

It makes it tempting to ignore the upgrade banner, and that’s not something a security plugin should be encouraging people to do.

On a related note, I’d really appreciate a changelog. The combination of updates with no substantial change and no indication of what has changed other than running diff myself is starting to set off alarm bells.
