Download Links for Older Versions of Spine-Godot

nickswebsite

I've been unable to find links to older versions of the Spine-Godot Run Times.

I've been on Godot 4.3 and Spine 4.2 and would like to upgrade to Godot 4.7 and Spine 4.3, but would like to do so incrementally. Basically upgrade to Godot 4.7 and keep Spine on the old version, make sure everything still works, then rinse and repeat for Spine. (Or, vice versa) But, I need access to the older run-times to do that, and I cannot seem to find them. I've been using the tarballs with the Godot editor bundled in.

Is there a link or page I missed?

nickswebsite If you want to use an older version of the spine-godot runtime, as Spinebot mentioned, an easy option is to look through the GitHub Actions history for an existing build from that time.

However, when spine-godot 4.2 was current, the latest version of Godot was 4.5.1, so I do not believe there is an existing build for Godot 4.7.

Therefore, you will need to compile either the GDExtension or the C++ engine module yourself. The process is explained in the following section of our documentation, so please refer to it for the necessary steps:

Great question! For downloading older versions of the spine-godot runtime, there are a couple of options available to you.

Option 1: Direct S3 Download Links

The spine-godot GDExtension downloads follow a predictable URL pattern:

https://spine-godot.s3.eu-central-1.amazonaws.com/{spineVersion}/{godotTag}/spine-godot-extension-{spineVersion}-{godotTag}.zip

So for example, for Spine 4.2 paired with a specific Godot 4.x build, you would substitute the appropriate version strings into that URL.

Option 2: GitHub Actions

You can browse and download older builds directly from the GitHub Actions page for the spine-godot extension:

https://github.com/EsotericSoftware/spine-runtimes/actions/workflows/spine-godot-v4-all.yml

There you can find the specific build artifacts for the Godot/Spine version combination you need.

A note on versioning

Keep in mind that the major.minor version of the spine-godot runtime must match the Spine Editor major.minor version used to export your skeletons. So your plan of upgrading Godot first while keeping Spine 4.2 is a solid approach — just make sure you grab the spine-godot runtime built for Spine 4.2 and your target Godot version. You can read more about version management in the Spine Runtimes versioning guide.

Turns out I was mistaken and was on Godot 4.5, so I was able to find an upgrade path: Godot 4.5 -> Godot 4.6, Spine at 4.2 -> Godot 4.6, Spine 4.3 -> Godot 4.7. I wasn't able to find Godot 4.5 with Spine at 4.3 unless it was a beta release (which I didn't look for). Everything went smoothly. Much more smoothly than I expected!

Thanks for the Help!
