In v2.3, DragonBones update its skeleton data format. It’s very different between v2.2 and v2.3. This is the details: https://github.com/DragonBones/SkeletonAnimationLibrary/wiki/Move-from-V2.2-to-V2.3
About CCArmature in cocos2d-x, according to my research, it migrates the DragonBones 2.1 form Actionscript3 to C++.. 2youyou2 made this, not me .
In practice, CCArmature has a little troubles, like this(in chinese): http://zengrong.net/post/1922.htm .
If I plan to support the DragonBones 2.3 in my tool. I must update the CCArmature to 2.3. It means I need migrate the DragonBones 2.3 Library to C**, what a enormous job!
I don’t know C** very much, authough I study it very hard, I’m afraid I don’t do it in 3 months.
Perhaps you can use CocoStudio ,it can import DragonBones files into the AnimationEditor. Please scroll down the page and look at the english description.
