 The new **paintOrder** mark option controls the [paint order](https://developer.mozilla.org/en-US/docs/Web/CSS/paint-order). The text mark’s paint order now defaults to *stroke*, with a stroke width of 3px and a stroke linejoin of *round*, making it easier to create a halo for separating labels from a busy background, improving legibility.
 
-The returned scale object now exposes *bandwidth* and *step* values for *band* and *point* scales.
-
-Fix a crash in default tuple accessors for *x* and *y* when data is undefined. Fix a bug where “none” with surrounding whitespace or capital letters would not be recognized as a valid color. When a channel is specified as a boolean value (*e.g.*, `fill: true`), it is now considered a constant value rather than undefined. Fix a bug where an identity color legend would be rendered as the text “undefined” instead of showing nothing. If scale options are declared, but the scale has no defined type, domain, or data, a scale is no longer constructed rather than a default linear scale. The vector mark now respects the *frameAnchor* option. The default boolean color schemes have been adjusted slightly so that the false value is slightly darker, improving contrast against a white background.
