Looks like CI ran with StatsBase 0.33 because something else is upper-bounding it.

[ararslan]

Ah, it's StatsModels. So we'll need JuliaStats/StatsModels.jl#291

Don't know why Julia nightly is failing, but the other versions run with StatsBase 0.34

[kleinschmidt]

I think nightly failures are the same as we see in StatsModels:

saturated linear model: Error During Test at /home/runner/work/GLM.jl/GLM.jl/test/runtests.jl:207
  Expression evaluated to non-Boolean

although looking at the tests, I don't see why (in my experience this is caused by @test_broken normally accepting non-boolean values in 1.8 or earlier)

We could backport #514 to the v1 branch. That PR fixed that issue.
