 NPY_RELAXED_STRIDE_CHECKING is now true by default.
 
+UPDATE: In 1.10.2 the default value of  NPY_RELAXED_STRIDE_CHECKING was
+changed to false for back compatibility reasons. More time is needed before
+it can be made the default. As part of the roadmap a deprecation of
+dimension changing views of f_contiguous not c_contiguous arrays was also
+added.

 Compatibility notes
 ===================
 
-fix swig bug in ``numpy.i``
+Relaxed stride checking is no longer the default
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+There were back compatibility problems involving views changing the dtype of
+multidimensional Fortran arrays that need to be dealt with over a longer
+timeframe.
+
+Fix swig bug in ``numpy.i``
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Relaxed stride checking revealed a bug in ``array_is_fortran(a)``, that was
 using PyArray_ISFORTRAN to check for Fortran contiguity instead of
 PyArray_IS_F_CONTIGUOUS. You may want to regenerate swigged files using the
 updated numpy.i
 
+Deprecate views changing dimensions in fortran order
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This deprecates assignment of a new descriptor to the dtype attribute of
+a non-C-contiguous array if it result in changing the shape. This
+effectively bars viewing a multidimensional Fortran array using a dtype
+that changes the element size along the first axis.
+
+The reason for the deprecation is that, when relaxed strides checking is
+enabled, arrays that are both C and Fortran contiguous are always treated
+as C contiguous which breaks some code that depended the two being mutually
+exclusive for non-scalar arrays of ndim > 1. This deprecation prepares the
+way to always enable relaxed stride checking.
