+## 2.7.0 - 2015-05-15
+
+### New rules
+* This element does not support ARIA roles, states and properties (`src/audits/AriaOnReservedElement.js`)
+* aria-owns should not be used if ownership is implicit in the DOM (`src/audits/AriaOwnsDescendant.js`)
+* Elements with ARIA roles must be in the correct scope (`src/audits/AriaRoleNotScoped.js`)
+* An element's ID must be unique in the DOM (`src/audits/DuplicateId.js`)
+* The web page should have the content's human language indicated in the markup (`src/audits/HumanLangMissing.js`)
+* 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`)
+* Avoid positive integer values for tabIndex (`src/audits/TabIndexGreaterThanZero.js`)
+* This element has an unsupported ARIA attribute (`src/audits/UnsupportedAriaAttribute.js`)
+
+### Enhancements:
+* Add configurable blacklist phrases and stop words to LinkWithUnclearPurpose (#99)
+* Detect and warn if we reuse the same code for more than one rule. (#133)
+* Force focus before testing visibility on focusable elements. (#65)
+* Use getDistributedNodes to get nodes distributed into shadowRoots (#128)
+* Add section to Audit Rules page for HumanLangMissing and link to it from rule (#119)

+
+### Bug fixes:
+* Incorrect use of nth-of-type against className in utils.getQuerySelectorText (#87)
+* AX_TEXT_01 Accessibility Audit test should probably ignore role=presentation elements (#97)
+* Fix path to audit rules in phantomjs runner (#108)
+* Label audit should fail if form fields lack a label, even with placeholder text (#81)
+* False positives for controls without labels with role=presentation (#23)
+* Fix "valid" flag on return value of axs.utils.getRoles (#131)
+
+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
+* findTextAlternatives doesn't throw TypeError if used on a HTMLSelectElement
+
+## 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
