We cannot support previous versions indefinitely. This will also encourage users to upgrade to newer versions of Spine.
In any case, I have cherry-picked the commit I mentioned earlier and pushed a new version.
One last note regarding your previous message:
i cannot do that
the assets are from a game i play
i cannot change the assets unfortunately
This implies that you do not own a Spine license.
Please read this paragraph regarding our license. Even if you have extracted the Spine assets from another application, you must own a Spine license to use the Spine runtimes (unless you are only evaluating the software or developing an SDK/library — in that case, your end users must hold a license).
A Spine license is a one-time purchase that grants you lifetime software updates and allows you to publicly showcase and publish your product.
