1.5.0

Hi, thanks for your report. test[True] works for me while test[0] does not. We are now supporting a boolean index, see #45061

@jbrockmendel I guess this is the correct behavior now?

[jbrockmendel]

test.loc[1] should definitely raise, but it may be that test.index._should_fallback_to_positional should be True, in which case the __getitem__ call should still work (but would have different behavior on test[::-1])
