Changelog

WCAG keeps moving. AI keeps moving.
So we keep updating.

Support for new AI models, verdict-accuracy improvements, and new features, published here in chronological order. In a field where both the accessibility standard and the judging models keep evolving, this page is where you can confirm the tool is alive and current.

Measured-verdict layer and accuracy benchmark

  • NewAdded a measured-verdict layer — target size (WCAG 2.5.8 / 2.5.5), reflow (1.4.10), text spacing (1.4.12), and focus visibility (2.4.7) are now decided from actual pixel and box measurements before the AI is ever asked. The measured values are kept in the evidence for each verdict.
  • NewIntroduced an accuracy benchmark — detection and false-positive rates are continuously measured against test pages with known, seeded defects. The deterministic and measured layers must hold 100% detection with zero false positives as a release condition.
  • NewJIS X 8341-3:2016 test-result summary — audit results can be summarized (in Japanese) with JIS-covered criteria (the 60 from WCAG 2.0) separated from reference criteria (the 26 added in WCAG 2.1/2.2).
  • NewStronger CI integration — SARIF 2.1.0 output (GitHub Code Scanning compatible) and a regression gate that diffs against the previous run to block only new violations, both added to the CLI.
  • ModelsAdded support for Gemini 3.6 Flash and Gemini 3.5 Flash Lite (the day after Google's announcement). The existing 3.5 Flash and 3.1-series models remain available.
Mid-July 2026

Contact channel and free onboarding

  • NewAdded a contact form (/contact). Submissions are tracked internally and a confirmation email is sent automatically.
  • NewPublished the guide to getting an API key for free (/free) — covering the Gemini free tier and OpenAI data sharing.
  • ImprovedImproved the accessibility of the landing page itself, reaching a Lighthouse accessibility score of 100 (dogfooding).
Early July 2026

Launch on the official domain, isolated-container audits

  • NewOfficially launched at a11y.effloow.com. Audits now run in an isolated container per URL and keep running even if you close your browser. BYOK API keys live only in container memory and are never stored.
  • NewStarted selling reports (detailed Excel report, VPAT®/JIS report) with credit-card checkout.
  • ImprovedIntroduced a fail-safe design that never consumes a credit for a failed audit (hold and automatic refund).
