Changelog

All notable changes to the four crates. They are versioned in lockstep. The format follows Keep a Changelog; the entries were backfilled from the Git history.

[0.11.0] - 2026-09-23

Changed

• All finding texts and rule hints are in English. message and help come from a rule core that serves three surfaces and arbitrary third-party pages; German sentences in an English interface were a visible break. Rule IDs, outcomes and severities are unchanged — anyone checking on identifiers will notice nothing. Anyone comparing message texts (snapshots in astro-post-audit or auditmysite) must re-approve them. Hence 0.11.0 and not 0.10.2.
• Comments, tests and docs/ stay German. What a tool outputs is translated.

[0.10.2] - 2026-09-23

Fixed

• headings/empty no longer reports a heading as empty when it gets its name via aria-labelledby or an image with alternative text. The same source is also on crates.io as 0.10.1; 0.10.2 is the version dependencies should rely on.

[0.10.0] - 2026-09-20

Changed

• images/alt-suspicious detects alt texts of one or two characters. The finding stays review.

[0.9.0] - 2026-09-20

Added

• links/generic-name: link text that says nothing about the target on its own, as review.

Fixed

• images/alt-missing no longer reports images that are removed from the accessibility tree via role="presentation" or aria-hidden="true".

[0.8.0] - 2026-09-20

Added

• landmarks/main-missing, landmarks/main-duplicate, landmarks/navigation-missing, landmarks/banner-missing, landmarks/contentinfo-missing.
• keyboard/skip-link-missing, aria/required-attribute-missing, headings/h1-multiple, zoom/viewport-missing.

[0.7.0] - 2026-09-20

Added

• Tier 3: RenderingRule, contrast/text-insufficient (WCAG 1.4.3) and contrast/text-undetermined.
• run_full for hosts with semantics and rendering, run_with_rendering for hosts without semantics.

Changed

• run and run_with_semantics record the contrast identifiers as CapabilityMissing.

[0.6.0] - 2026-09-19

Added

• lists/item-outside-list: a list item without a surrounding list.

[0.5.0] - 2026-09-19

Added

• lists/term-without-definition, tables/presentational-with-headers, tables/name-missing (as review) and zoom/viewport-scale-limited.

[0.4.0] - 2026-09-19

Added

• lists/empty: a list without items.

Changed

• keyboard/positive-tabindex has the default severity high.

Fixed

• zoom/viewport-locked compares the content value case-insensitively.
• lists/invalid-structure takes role="list" and role="listitem" into account; role="presentation" on the list suppresses the list findings.
• tables/header-missing recognizes header cells via role="columnheader" and role="rowheader" and also checks role="table".

[0.3.0] - 2026-09-19

Added

• Finding carries role, name and rule_name.
• Extra: tool-specific addition to a finding, never serialized and not part of its identity.
• RuleRun carries viewport and wcag.

Breaking

• New fields on Finding and RuleRun.

[0.2.0] - 2026-09-18

Breaking

• Meta::id becomes Meta::ids and declares all finding identifiers of a rule. RuleRun is kept per identifier, so that rule_runs and findings use the same set of names.

[0.1.0] - 2026-09-18

Added

• a11y-report: finding and report model.
• a11y-dom and a11y-rules: document model with capability tiers and the first rules.
• accname: Accessible Name and Role Computation per accname 1.2 and HTML-AAM 1.0.
