@J.M. Wu Apologies, we've been meaning to make a version select box for the example pages for a long time!
3.8 is very old and doesn't have the ability to download examples. In 4.0+ versions, you can choose from many more examples within Spine and it will download them for your current version.
@Misaki using a newer version to save JSON for an older version may work, especially when the older version is just 1-2 versions back, but probably not 4.x to 3.8. Curves will be lost, among other things. We shouldn't suggest it for any normal workflow, it can cause data loss and it's really for disaster recovery only (eg I did lots of work with a newer version and want to go back 1 version to preserve my work).
