2.7.4

• Added: `mai_testimonials_render_schema` filter to disable all testimonial schema output.
• Changed: Updated the updater.
• Changed: `reviewBody` is now plain text instead of HTML, and the Review schema builder is shared by both block paths.
• Fixed: Review schema now includes `datePublished` (ISO-8601), clearing the Google "Review datePublished" warning.
• Fixed: `aggregateRating` now reports the average rating with `bestRating` of 5 instead of summed values.
• Fixed: Reviews collected via the Mai Grid block now output schema (previously dropped).
• Note: Google does not show rich results for self-serving Organization-level reviews/ratings, so star snippets may not appear even with valid markup.
