3.1.0
-----
* [!] Major refactoring. Broken into `SliderBase`, `ClickableRail`, and
`SliderValueRange` classes, and `Y.Slider` is the product of
`Y.Base.build(…)` of these. `SliderBase` is responsible for rendering the UI
and broadcasting `slideStart`, `slideEnd`, and `thumbMove` events.
`ClickableRail` adds support for clicking on the `rail` to move the `thumb`.
`SliderValueRange` adds support for `min`, `max`, and `value` attributes.
Values are integers ranging from 0 to 100 by default. `Base.build()` in
different value algorithms or extensions to specialize from `SliderBase`.
* [!] `railSize` attribute renamed to `length`.
* [!] `maxGutter` and `minGutter` attributes removed. Use CSS and/or apply
manually via `slider._dd.con.set('gutter', …);`.
* [!] `rail`, `thumb`, `thumbImg` `Node` attributes removed, as well as
`HTML_PARSER` support. Progressive enhancement stems from a value source,
not a markup source. Various progressive enhancement extensions will arrive
in future versions.
* Sam skin updated and 7 new skins added (`sam-dark`, `round`, `round-dark`,
`capsule`, `capsule-dark`, `audio`, `audio-light`).
* New markup and CSS structure including separate shadow image (set to same
image as thumb, positioned via CSS ala sprite.
* Thumb placement method changed from `setXY()` and `DD` positioning methods
to simpler `setStyle('left', x)` or `top` for vertical Sliders. Allows
rendering and modifying in hidden containers without the need to `syncUI()`
when making visible. Still recommended to call `syncUI()` if rendered off
DOM, but may not be necessary if using Sam skin. YMMV.
3.0.0
-----
* Removed noop `_setValueFn()` and the setter config for the `value`
attribute.
* Renamed static protected `AXIS_KEYS` to `_AXIS_KEYS`.
