While browsing DeviantART, I came across a post that the newest version of the drawing software Manga Studio, has been released. I checked the official website, and sure enough, Manga Studio 5 is available for purchase. Upon further research, I learned that the full (EX) version is not yet available, but it will be this summer.

Personally, I hope they allow upgrades from version 3, not just version 4. If they don't allow me to skip to the current version, I will be miffed. I'm still trying to get a handle on EX 3, so that's why I never upgraded.
