Release date: 2026-05-26

Enhancements:

• Adds a Logger panel to the Yoast Test Helper (Tools → Yoast Test) that replaces Yoast SEO’s NullLogger via the wpseo_logger filter and persists captured entries to either a custom DB table or a JSONL file.
• Adds a “MyYoast OAuth overrides” card that swaps Yoast SEO’s MyYoast OAuth issuer + software statement + initial access token at runtime, fetched from {issuer}/api/oauth/software-statements using a developer-supplied PAT. Lets you point Yoast SEO at a non-production MyYoast environment (staging, local, custom URL) without editing wp-config.php.
