Hi everyone,
Sorry for the silence but I was away at a trade show. This update was focused on fixing critical bugs/crashes as shown below.
Enhancements in Anime Studio® Debut/Pro 10.1.3 Update
    --None--
Fixes in Anime Studio® Debut/Pro 10.1.3 Update
    Corrected User Content Library problems that affected Mac OS X 10.9, 10.10 and Windows.
    Fixed crash when adding key frames.
    Fixed other minor issues.
As a reminder, you should get an automatic reminder for updates when you start your application. If you don't for some reason, it is available on the website here: 
http://my.smithmicro.com/anime-pro-updates.html.
In the future I'll be sure to share the readme text when I post about updates so that you all know what has changed. Sorry for the confusion.
Also, I saw in the thread that someone said they haven't heard much from the Smith Micro team lately, well that's because they've had their heads down working on the next version. Don't worry, everyone is still here.
