Releases: dequelabs/axe-core
Release 4.10.1
Because a few false positives were fixed, this release may see the number of reported issues go down. In pages with lots of very similar elements a performance bottleneck was fixed, allowing axe to finish sometimes up to 10x faster, although for most pages there won't be a difference. Lastly there is a small change to the ancestry selector of elements in shadow DOM. These weren't always guaranteed to be unique. The change means deduplication based on ancestry selectors may not work between 4.10.1 and older versions.
Bug Fixes
- aria-allowed-role: add form to allowed roles of form element (#4588) (d462d67), closes /github.com/dequelabs/axe-core/blob/develop/lib/standards/html-elms.js#L264
- axe.d.ts: add typings for preload options object (#4543) (72e269f)

- rules: Change "alternate text" to "alternative text" (#4582) (31e0f61)
Release 4.10.0
This axe-core release introduces a new rule for testing the HTML summary element. Additionally, a number of false positives have been fixed. Upgrading to this release may therefore both increase, or decrease the number of issues found on a website. Most likely the impact of upgrading from axe-core 4.9.2 to axe-core 4.10.0 should be minimal.

Release 4.8.4
This release should not result in different issue numbers. For TypeScript users, an error in type definitions has been corrected. This release could require a correction to how axe-core types are used. This release may change selectors on elements with the xmlns attribute, as the selectors axe-core prosed with those was invalid. Deduplication based on selectors between this and and prior versions of axe-core can fail because of this change.

Release 4.8.3
Release 4.8.2
Release 4.8.1
Release 4.8.0
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.

Release 4.7.2
This release corrects the Trusted Tester v5 tags, which were introduced in 4.7.0, and it addresses a few false positives which for pages with forms may result in a few less issues found.
