The commit message "Added scripting to generate indexes of roles, properties and states" indicates that there should not have been any functional change to the specification, but in fact 'aria-labelledby' was changed in this commit. The ARIA 1.1 working draft contains the wording of 'aria-labelledby' introduced by commit 05f1df89: > If the label text is visible on screen, authors should use aria-label. Use > aria-label only if the interface is such that it is not possible to have a > visible label on the screen. As required by the text alternative computation, > user agents give precedence to aria-label when computing the accessible name > property. It should state: > If the label text is visible on screen, authors should use aria-labelledby. Use > aria-label only if the interface is such that it is not possible to have a > visible label on the screen. As required by the text alternative computation, > user agents give precedence to aria-labelledby when computing the accessible name > property.
