The downgrade tests got skipped :(

[ChrisRackauckas]

You have to re-enable them

[ParamThakkar123]

@ChrisRackauckas All downgrade tests seem to pass. I think the one that fails isn't able to find julia executable due to some reason. I will retrigger this before merging to ensure it passes

@ChrisRackauckas

Run julia-actions/setup-julia@v2
Error: Unable to locate executable file: julia. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

getting this from the CI

That's because the machine ran out of memory. Just rerun 😅

@ChrisRackauckas There's an error in the CI which says:

I tried the path approach where I added the paths of OrdinaryDiffEqCore to some libraries. Is there a better fix for this ?

[ChrisRackauckas]

tests fail

[ParamThakkar123]

@ChrisRackauckas I retriggered CI but the Downgrade tests seem to fail with the same manifest error ? Should I rerun it with v2.2.2 ?
