 * *dsv*.parse now exposes column names as *data*.columns; available to row conversion functions
-* *dsv*.format now takes an optional array of column names
+* *dsv*.format now takes an optional array of column names, useful for filtering columns and explicitly specifying the column order

+symbols instead of strings for -in, -out, -in-out, e.g.:
+
+* d3.ease("cubic-in") -> d3.easeCubicIn
+* d3.ease("cubic-out") -> d3.easeCubicOut
+* d3.ease("cubic-in-out") -> d3.easeCubicInOut

+sensible default aliases if no -in, -out, or -in-out:

+* d3.easeCubic ↦ d3.easeCubicInOut

+* d3.ease("elastic", *a*, *p*) ↦ d3.easeElastic.amplitude(*a*).period(*p*)
+* d3.ease("back", *s*) ↦ d3.easeBack.overshoot(*s*)

+fix confusion around elastic, bounce and back easing:

+* “elastic-out” ↦ d3.easeElasticIn
+* “elastic-in” ↦ d3.easeElasticOut
+* “elastic-out-in” ↦ d3.easeElasticInOut
+* “bounce-out” ↦ d3.easeBounceIn
+* “bounce-in” ↦ d3.easeBounceOut
+* “bounce-out-in” ↦ d3.easeBounceInOut
+* remove “-out-in” easing
+* fix default overshoot for backInOut
+* fix parameter interpretation for elasticInOut
+
+other improvements:
+
+* optimizations (fewer closures, more inlining)
+* better accuracy
+* remove implicit clamping
