This axe-core release makes various changes to impact. As a result issues previously reported in one rule may now be reported under a different rule. In rarer cases, the impact under which an issue is reported may change. This release has further deprecated the duplicate-id and duplicate-id-active rule, along with setting the duplicate-id-aria to always report as "needs review" rather than as a violation. As these three rules are fairly common causes of issues, this change may result in the total issue reported going down significantly.

Consistent Rule Impact

This release changes it so that a rule never changes what impact it reports. To facilitate this while without changing the impact on certain issues, some rules have been split. The following changes were involved:

  • Deprecate impact on checks; use rules instead (#4114) (2cc5547)
  • add rule aria-deprecated-role (#4074) (03f2771)
  • add rule aria-conditional-attr (#4094) (d417630)
  • aria-input/toggle-field-name: set impact always to serious (#4095) (e031d68)
  • aria-prohibited-attr: add rule aria-prohibited-attr (#4088) (7b115d3)
  • impact: aria-roles / aria-valid-attr-value is always "critical" (#4112) (5cc8041)
  • impact: scope-attr-valid is always "moderate" (#4113) (131f552)

Other Features

  • deprecate & disable duplicate-id / duplicate-id-active (#4071) (733c45e)
  • duplicate-id-aria: set to review on fail and tag as wcag412 (#4075) (9f1a3e3)
  • add EN.301.549 tags to rules (#4063) (de3da89)
  • checks: enable help-same-as-label, but remove from rules (#4096) (034038a)
  • new-rule: aria-braille-equivalent finds incorrect uses of aria-braille attributes (#4107) (6260a2f)
  • page-no-duplicate-banner/contentinfo: deprecate options.nativeScopeFilter, take into ancestors with sectioning roles (#4105) (c6e07be)

Type Fixes & Improvements

Various improvements were made to the types. Potentially the most impactful of which is that the target and ancestry property now return as UnlabelledFrameSelector instead of as string[], which is incorrect for selectors involving shadow DOM. This may create some issues during migration for any code that has been incorrectly assuming these two properties have the string[] type.
