- Active Storage disables libvips “unfuzzed” image loaders and savers (e.g., BMP, ICO, PSD, SVG, JPEG‑XL, JPEG‑2000), causing Vips::Error for those formats
- Applications must adjust config or remove ruby‑vips, and now require libvips ≥ 8.13 and ruby‑vips ≥ 2.2.1; boot will raise a RuntimeError if requirements are not met
- The change fixes CVE‑2026‑66066 and is a breaking change for apps that depend on the disabled image types
