v0.5.5

Patch Changes

• #627 0485441 Thanks @eps1lon! - Ensure certain babel helpers aren't required

  Source:

  -const [item] = list;
  +const item = list[0];

  Transpiled:

  -var _trim$split = list.trim().split(" "),
  -_trim$split2 = _slicedToArray(_trim$split, 1),
  -item = _trim$split2[0]
  +var item = list[0];

• #629 383bdb6 Thanks @eps1lon! - Use label attribute for naming of <optgroup> elements.

  Given

  <select>
  	<optgroup label="foo">
  		<option value="1">bar</option>
  	</optgroup>
  </select>

  Previously the <optgroup /> would not have an accessible name.
  Though 2D in accname 1.2 could be interpreted to use the label attribute:

  Otherwise, if the current node's native markup provides an attribute (e.g. title) or element (e.g. HTML label) that defines a text alternative, return that alternative [...]

  This was confirmed in NVDA + FireFox.
