New Timthumb Multisite Compatible?

Is the new timthumb (which was updated to correct vulnerabilities in the old version) compatible with Wordpress Multisite? Or does new new timthumb need to be edited as described here:

For those running Wordpress Multisite, when you upgraded timthumb did you need to make any modification?
