SMTPing 1.2.2 Revision 19 is available now :) (News & notices)
We've uploaded a maintenance release that didn't change SMTPing's main version digits for one simple reason: SMTPing's core components didn't change.
We've improved the Inno Setup scripts for all packages. Those users to reinstall the whole package instead of just updating will not get the core scripts updates.
This update is not critical or mandatory, so if you don't have the time to update right now, don't sweat about it :)
