+Scales now generate ticks in the same order as the domain: if you have a descending domain, you now get descending ticks. This changes applies to time scales as well, and affects the order of tick elements generated by [axes](#axes-d3-axis). For example:
 
-* quantitative scales generate ticks in the same order as the domain
-* non-linear quantitative scales are more accurate
-* *log*.tickFormat now filters by default to 10 ticks
-* better *log*.ticks filtering for large domains
-* *time*.ticks and *time*.nice now only accept time intervals (no string alias)
+```js
+d3.scaleLinear().domain([10, 0]).ticks(5); // [10, 8, 6, 4, 2, 0]
+```
+
+Non-linear quantitative scales are slightly more accurate. [Log tick formatting](https://github.com/d3/d3-scale#log_tickFormat) now assumes a default *count* of ten, not Infinity, if not specified. Log scales with  domains that span many powers (such as from 1e+3 to 1e+29) now return only one [tick](https://github.com/d3/d3-scale#log_ticks) per power rather than returning *base* ticks per power.

 new ordinal scale API!
 new *ordinal*.unknown lets you control whether the domain is implicitly extended.
 d3.scaleOrdinal constructor now takes an optional *range*.
