@lkdvos it looks like this may have broken a certain contraction pattern in TensorOperations, I see a failure in this test: https://github.com/ITensor/ITensors.jl/blob/v0.7.3/NDTensors/src/lib/TensorAlgebra/test/test_basics.jl#L163-L165 where we are looping over a number of tensor contraction patterns.

I'm having trouble reproducing it with a minimal example.

From what I can see here, this should not related to the compat entry, and really is a bug that probably existed before. I'll have a look in a second

I see what happened: somehow there is a compat problem, and the installed version of TensorOperations in the failing tests is 0.7.1, which is incredibly outdated. I am not entirely sure why this is happening, as this should probably be excluded by the compat entry of the packages here, since the order of arguments changed.

I guess this is because you don't have TensorOperations as a dependency, and thus don't have a compat entry for it?

As a sidenote, this problem should resolve itself as soon as the tests automatically take the new registered version of TensorOperations, JuliaRegistries/General#119490

I see, that would explain it. Thanks for investigating. Yeah, TensorOperations is just being used for testing right now but I guess we could put a compat entry in test/Project.toml.

Yes, looks like that fixed it.
