I am currently working alone on animation and game development using Spine for Unity. First, I'd like to express my gratitude to EsotericSoftware for creating Spine. The progress since version 4.0, starting with the integration of graphs and dope sheets, has been remarkable, and now it even includes its own physics processing, which is extremely convenient for a solo developer like myself. Although I used Unity's physics processing before, the current 4.2 beta version allows for direct simulation in Spine and subsequent import, which is very helpful.
However, as it is still a beta version, I've noticed a few issues. Given the nature of my project, which heavily relies on physics features, I'm using the most stable beta version of 4.2 (in my test), as it's still in beta. I would like to use the official version of Spine for my next project.
Could I inquire about the approximate release date of a stable official build?
