In this patch release of phase 2, we have added additional spy attributes.
Attributes included,

1. Href: - The href attribute specifies the URL of the page that the link ports to. If the href attribute is not present, the <a> tag will not be a hyperlink.
2. Src: - The src attribute specifies the location (URL) of the external resource.
3. Aria-label: - The aria-label attribute defines a string value that labels an interactive element.
4. Aria-role: - ARIA roles provide semantic meaning to content, allowing screen readers and other tools to present and support interaction with object in a way that is consistent with user expectations of that type of object
5. colName: - The name of the table column that contains UI element
6. rowName: - The name of the table row that contains UI element
7. tableRow: - Table row number that contain UI element
8. tableCol: - Table column number that contain UI element

Earlier the web automation activities were restricted to function using one attribute of the element that had to be automated, Whereas in the latest version of Web automation multiple attributes can be fed as input to the activity and when all those attribute value are available the execution takes place and therefore the "Executeby" option is not required, hence that option is not available.
