 Treemap tiling is now [extensible](https://github.com/d3/d3-hierarchy#treemap-tiling) via [*treemap*.tile](https://github.com/d3/d3-hierarchy#treemap_tile)! The default squarified tiling algorithm, [d3.treemapSquarify](https://github.com/d3/d3-hierarchy#treemapSquarify), has been completely rewritten, improving performance and fixing bugs in padding and rounding. The *treemap*.sticky method has been replaced with the [d3.treemapResquarify](https://github.com/d3/d3-hierarchy#treemapResquarify), which is identical to d3.treemapSquarify except it performs stable neighbor-preserving updates. The *treemap*.ratio method has been replaced with [*squarify*.ratio](https://github.com/d3/d3-hierarchy#squarify_ratio). And there’s a new [d3.treemapBinary](https://github.com/d3/d3-hierarchy#treemapBinary) for binary treemaps!
 
-Treemap padding has also been improved. The treemap now distinguishes between outer padding ([*treemap*.paddingOuter](https://github.com/d3/d3-hierarchy#treemap_paddingOuter)) that separates a parent from its children, and inner padding ([*treemap*.paddingInner](https://github.com/d3/d3-hierarchy#treemap_paddingInner)) which separates adjacent siblings. You can also set the [top-](https://github.com/d3/d3-hierarchy#treemap_paddingTop), [right-](https://github.com/d3/d3-hierarchy#treemap_paddingRight), [bottom-](https://github.com/d3/d3-hierarchy#treemap_paddingBottom) and [left-](https://github.com/d3/d3-hierarchy#treemap_paddingLeft)outer padding separately. There are new examples for the traditional [nested treemap](http://bl.ocks.org/mbostock/911ad09bdead40ec0061) and for Lü and Fogarty’s [cascaded treemap](http://bl.ocks.org/mbostock/f85ffb3a5ac518598043). There’s also a new example showing how to use [d3.nest with d3.treemap](http://bl.ocks.org/mbostock/2838bf53e0e65f369f476afd653663a2).

 The space-filling layouts [d3.treemap](https://github.com/d3/d3-hierarchy#treemap) and [d3.partition](https://github.com/d3/d3-hierarchy#partition) now output *x0*, *x1*, *y0*, *y1* on each node instead of *x0*, *dx*, *y0*, *dy*. This improves accuracy because the edges of adjacent cells are now exactly equal, rather than sometimes being slightly off due to floating point math. The partition layout now supports [rounding](https://github.com/d3/d3-hierarchy#partition_round) and [padding](https://github.com/d3/d3-hierarchy#partition_padding).
