I think this depends on a specific setup for releases; what I can do is copy over the process I do for FNA releases which recursively grabs submodules and trims all the git dotfiles.

Sorry for the runaround, expect an archive of 2.4 later this weekend. I'll update the linked issue accordingly!

[i0ntempest]

Thanks, just confirming this will be done (automatically?) for future releases as well?

[flibitijibibo]

Probably not automatically, but I have scripts for this that I can copy over from my other projects that'll make it super quick.

[i0ntempest]

Sure. Still think an automatic workflow would be easier but I’m happy as long as full tarballs are provided.

Release has been updated with VVVVVV-2.4.zip, which contains all the submodules with the quirks included.
