Upgrade ARC Rules engine to v5.7.5 which includes the following bug fixes:
- New Rule: listItemNotDirectChild Alert when the element is not a direct child of a list element; e.g. ol, ul, menu. This rule focuses on the relationship between HTML elements instead of the use of ARIA roles.
- Updated listItemHasParent so that role=listitem can now be child of <ul> and <li> can be child of role=list.
- Updated listIsProperlyStructured so that role=listitem can now be child of <ul> and <li> can be child of role=list for detecting empty lists.
- Updated: Added WCAG 2.0 Standard to ARIA related automated rules.
- Updated: All rules are now associated with one or more affected groups.
- Change: ariaAttributeMissingRequiredValue and ariaAttributeMissingValueWithoutDefault is recategorized as an Alert.
- Change: navigationLinkLabelInName to strip out punctuation from the visible text when comparing to aria-label.
- Change: cssTextFormatting, htmlItalic, htmlStrikeThrough, and htmlUnderline titles now differenciate between tests of elements vs. styles.
- Change: dialogModalHasTitle covers alertdialog now.
- Fix: htmlIDIsUnique Escape quotes before checking for duplicates.
- Fix: noHeadingText and emptyListItem when heading/list item contain text within child elements.
- Fix: Removed allowed attributes exception for the ARIA generic role, as this feature has now been implemented globally.
- Fix: Lists of applied and not applied rules contain the correct values in the response from the engine.

Upgrade ARC Rules engine to v5.7.3 which includes the following bug fixes:
- Fix: imageSVGHasRole now ignores svg elements if they are not in the accessibility tree.
- Fix: imageActiveSVGHasLabel now ignores svg elements with role only and no tabindex.
- Fix: pageCanBeZoomed to exclude user-scalable values between -1 and 1.
- Change: accessKeyUsedMultipleTimes is recategorized as an Alert.

Upgrade ARC Rules engine to v5.7.3 which includes the following bug fixes:
- Fix: iframe elements now have access to the accessibility tree context for where they occur in the DOM and can utilize this information during a scan.
- Fix: ARIAAttributeNotAllowed incorrectly flagged header and footer elements that included a valid aria-label attribute.
- Fix: buttonElementHasLabel now correctly ignores buttons that are not in the accessibility tree.
- Fix: DataCloneError: Failed to execute 'postMessage' on 'Window': HTMLElement object could not be cloned.
- Change: navigationUnfocusableLinkPurpose now ignores a elements with a tabindex="-1" and a valid href as they are considered implementations of the roving tabindex technique.

Note: Some users may see a decrease in their results if they have been properly utilizing the roving tabindex technique.

- Change: Elements that are hidden by their parent are now tested first so that individual child states do not override the parent hidden state.

Note: Some users may see a fluctuation in the their7 results due to this change as it involved an update to the order of operations for determining whether an element is visible in the accessibility tree based on its position within the DOM.

- Change: The response from the engine now returns additional information needed by the ARC Platform including: detailed information about the page and its metadata and additional metadata for each node returned including attributes and styles.

- fix: Scan results are not limited to only the selected node
- fix: ARC Toolkit does not highlight background images, tables, or ARIA Usage
- fix: "Only Show" doesn't filter results to selected options
