 The [vector mark](./README.md#vector) now supports the **shape** constant option; the built-in shapes are *arrow* (default) and *spike*. A custom shape can also be implemented, returning the corresponding SVG path data for the desired shape. The new [spike convenience constructor](./README.md#plotspikedata-options) creates a vector suitable for spike maps. The vector mark also now supports an **r** constant option to set the shape radius.

 The new [geoCentroid transform](./README.md#plotgeocentroidoptions) and [centroid initializer](./README.md#plotcentroidoptions) compute the spherical and projected planar centroids of geometry, respectively.
 
-Diverging scales now correctly handle descending domains. When the stack **order** option is used without a *z* channel, a helpful error message is now thrown. The **clip** option *frame* now correctly handles band scales. Using D3 7.8, generated SVG path data is now rounded to three decimal points to reduce output size.
+The **interval** option now supports named time intervals such as “sunday” and “hour”, equivalent to the corresponding d3-time interval (_e.g._, d3.utcSunday and d3.utcHour). The [bin transform](./README.md#bin) is now many times faster, especially when there are many bins and when binning temporal data.

Fix a crash when a facet scale’s domain includes a value for which there is no corresponding facet data. The bin, group, and hexbin transforms now correctly ignore undefined outputs. Upgrade D3 to 7.8.2.
