Incompatibility with Julia 1.12 due to missing `Base.module_keys`

[kbarros]

There are a couple places where JLD2 currently depends on Base.module_keys:

This function is no longer available on nightly (1.12) versions of Julia, which makes JLD2 incompatible.

Will there be a replacement ?

[giordano]

This was changed in JuliaLang/julia#56329, my understanding is that Base.module_keys was replaced by Base.loaded_modules_order (but with a different type, and apparently also a different list of modules)

[kbarros]

Another option to consider is values(Base.loaded_modules). I'm not sure how that's distinct from Base.loaded_modules_order. Either way, these functions seem available across Julia versions (I looked at 1.10, 1.11, 1.12-dev).

Here are some links to show how Base.loaded_modules_order gets filled in different versions:
https://github.com/JuliaLang/julia/blob/release-1.10/base/loading.jl#L1859-L1861
https://github.com/JuliaLang/julia/blob/master/base/loading.jl#L2530-L2531

Of course, all of these functions seems to be private. Ideally one could find an alternative that's in the public API?

[JonasIsensee]

Since I haven't needed to drop support for julia 1.6, yet, I went with values(Base.loaded_modules) which has been around forever. (Base.loaded_modules_order was added in julia v1.9)

I'd love an alternative using public API only, but that's no reason to leave it broken until then.

A new release with fix should hopefully be out later today.
