NumPy 1.14.0 Release Notes
..., considering a buffer of all zeros as false, and anything else as true. Checks for V0 can still be done with arr.dtype.itemsize == 0. MaskedArray.squeeze never returns np.ma.masked np.squeeze is documented as returning a view, but the ma...
NumPy 1.16.0 Release Notes
...at aligned structured dtypes may now have a different size. For instance, np.dtype('c8,u1', align=True) used to have an itemsize of 16 (on x64/gcc) but now it is 12. More in detail, the complex64 type now has the same alignment as a C-struc...
NumPy 1.8.0 Release Notes
...se otherwise. The typical problem we’ve seen so far is C code that works with C-contiguous arrays, and assumes that the itemsize can be accessed by looking at the last element in the PyArray_STRIDES(arr) array. When relaxed strides are in e...
