No member named `crend` in `xt::fixed_shape<N>`

[danielcjacobs]

Compiler: clang 17.0.0
Xtensor version: 0.26.0
OS: macOS Sequoia 15.4

I used to be able to do operations with fixed shape arrays like in this snippet:

#include <xtensor/containers/xfixed.hpp>
#include <xtensor/containers/xtensor.hpp>
#include <xtensor/views/xview.hpp>

int main() {
	auto arr       = xt::xtensor<double, 1>({5, 5, 5, 5, 5});
	auto fixed_arr = xt::xtensor_fixed<double, xt::xshape<3> >{1, 2, 3};

	xt::view(arr, xt::range(0, 3)) = fixed_arr + 1;
}

However, this code no longer compiles, as I get this error about xt::fixed_shape not having a .crend() member:

What's going on here and why is this happening when it was fine with previous versions of xtensor (up to 0.25.0)?
