I currently have committed here, the wordpress-tests submodule.
Github tells me that the version attached is the latest version of the submodule:
wordpress-tests @ d983429
However, I wish to attach to an older version, like this
wordpress-tests @ 460b9c4
The specific Github tree URL to the new version is:
https://github.com/nb/wordpress-tests/tree/460b9c4ad9db7eea4710f151851060ae1921ea7c
How can I attach the older version to my program?
Took me a while to figure it out but basically when you do the gitattributes file, use the tree of the commit.
