The new release contains the refactored and cleaned-up GUI subsystem, a new input subsystem, more composing functions, etc.
Also, since I got a full-time job, I have limited time to work on my software development projects, especially my engine, which grew pretty complex. I would like to have a few testers at least. I cannot provide any financial compensation, however I do plan to take game development in D to the next level (most likely this very same engine), so I might count you into my project. I also looking for other kind of creatives, mainly pixel artists, but I guess this is not the place for that.
