Abstract: Highlights Slicing/indexing overhaul for a more NumPy-like user experience. Special thanks to Ben Bourgart @ben-bou and the TerrSysMP group for this one. Warning for distributed arrays: breaking change! Indexing one element along the distribution axis now implies the indexed element is communicated to all processes. More flexibility in handling non-load-balanced distributed arrays. More distributed operations, incl. meshgrid . For other details, see the CHANGELOG .
