Release 4.11.1

Release summary

This release addresses a number of false positives, which may result in a slightly lower number of issues reported. It also resolves a problem that caused the color contrast rule skip a page in edge cases. A page that wasn't tested because of this edge case may now be tested, and so could see new color contrast issues reported.

Lastly this rule corrects a few of the newly released RGAA tags, so when running an RGAA ruleset which rules run, and how they are mapped to RGAA is slightly different.

• valid-lang: update valid-langs for newer language codes (#4966) (c3f5446), closes #4963

Release 4.11.0

This release adds the new RGAA standard to many rules. Of particular note is that some best practice rules under WCAG are required under the RGAA standard: focus-order-semantics (experimental), region, skip-link, table-duplicate-name. This means that these rules are tagged as both best-practice and RGAAv4. Applications which are filtering rules based on the best-practice tags will need to update the logic in order to handle RGAA rules that are tagged best-practice.

Release 4.10.3

This release addresses a few performance issues, corrects a few typos, and addresses a few inconsistencies between axe and the latest web standards. This may, but is unlikely to reduce the total number of issues found.

Bug Fixes

• aria-allowed-role: Add math to allowed roles for img element (#4658) (f6dddd9), closes #4657
• captions: fix grammar in captions check incomplete message (#4661) (3ef7058)

• locale: proofread and updated de.json (#4643) (910cdb2)
• no-autoplay-audio: don't timeout for preload=none media elements (#4684) (b7f1ad1)
• target-size: do not treat focusable tabpanels as targets (#4702) (67d4e4f), closes #4421 #4701

Release 4.10.2

This release prevents axe from sometimes crashing when a page changes in the middle of a test.

Bug Fixes

• get-ancestry: don't error when there is no parent (#4617) (6c07102)

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)
• button-name,input-button-name,input-img-alt: allow label to give accessible name (#4607) (364eb72), closes #4472 #3696 #3696
• get-ancestry: add nth-child selector for multiple siblings of shadow root (#4606) (bdd94a2), closes #4563
• 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.

Features

• new-rule: summary elements must have an accessible name (#4511) (0d8a99e), closes #4510

Bug Fixes

• utils/get-selector: ignore 'xmlns' attribute when generating a selector (#4303) (938b411)

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.

Bug Fixes

• Add LICENSE-3RD-PARTY.txt file (#4304) (139c553)
• avoid reading element-specific node properties of non-element node types (#4317) (a2a6935), closes #4316 #4316

• d.ts: RunOptions.reporter can be any string (#4218) (80de793)
• utils/get-selector: ignore 'xmlns' attribute when generating a selector (#4303) (8c68546)

Release 4.8.3

This release will not change axe-core's results. Only needed when used with old versions of NodeJS.

Bug Fixes

• add Object.values polyfill for node <=6 (#4274) (b39b0e6)
