I just noticed the same thing yesterday! I don’t know if Enhancesoft sent out an email notification, but I know that I did not receive one.
I should have a version of osTicket Awesome for 1.10.5 ready this week. I’m not sure how long it will take to prepare a release for 1.11.0. It includes some significant changes and new features, so I can’t make any promises at this point.
In any event, as a paying customer you will receive email notifications as each become available.
