* An element's ID must not be present in more that one aria-owns attribute at any time (`src/audits/MultipleAriaOwners.js`)
* ARIA attributes which refer to other elements by ID should refer to elements which exist in the DOM (`src/audits/NonExistentAriaRelatedElement.js` - previously `src/audits/NonExistentAriaLabeledBy.js`)
* Elements with ARIA roles must ensure required owned elements are present (`src/audits/RequiredOwnedAriaRoleMissing.js`)

Note: this version number is somewhat arbitrary - just bringing it vaguely in line with [the extension](https://github.com/GoogleChrome/accessibility-developer-tools-extension) since that's where the library originated - but will use semver for version bumps going forward from here.

## 0.0.5 - 2014-02-04

### Enhancements:
* overlapping elements detection code made more sophisticated
* axs.properties.getFocusProperties() returns more information about visibility
* new axs.properties.hasDirectTextDescendant() method with more sophisticated detection of text content

### Bug fixes:
* FocusableElementNotVisibleAndNotAriaHidden audit passes on elements which are brought onscreen on focus
* UnfocusableElementsWithOnclick checks for element.disabled
* Fix infinite loop when getting descendant text content of a label containing an input
* Detect elements which are out of scroll area of any parent element, not just the document scroll area

## 0.0.4 - 2013-10-03

### Enhancements:

* axs.AuditRule.run() has a new signature: it now takes an options object. Please see method documentation for details.
* Audit Rule severity can be overridden (per Audit Rule) in AuditConfig.

### Bug fixes:

* axs.utils.isLowContrast() now rounds to the nearest 0.1 before checking (so `#777` is now a passing value)
* MainRoleOnInappropriateElement was always failing due to accessible name calculation taking the main role into account and not descending into content (now just gets descendant content directly)
* UnfocusableElementsWithOnClick had a dangling if-statement causing very noisy false positives
