The previous version has a small but annoying bug. If you approve comments from several posts at one time, everyone subscribed to those posts will get notifications for all the approved comments! Mark applied my patch 3 weeks ago but people are slow to update.
In the last 3 days I’ve received extra notifications from 2 blogs. I emailed the first blog owner, but then Pat moderated some comments this morning and I decided this was the easiest way to get the word out!
Go on, update your plugin! Your blog visitors will thank you!
