2.1.18 - WordPress 7.0 compatibility

Changes

• Move Nova block metadata, manual JS registrations, generated sidebar blocks, and legacy PHP fallback registrations to Block API v3 for WordPress 7.0 iframe editor readiness.
• Remove Nova-owned WP 7 editor console warnings from the Headline block, editor preferences, and Nova Blocks Tools sidebar.
• Fix duotone overlay filter behavior by hiding the strength control and neutralizing the rendered strength when duotone overlays are selected.
• Include the recent legacy Hero block compatibility, Site Editor dirty-state cleanup, mobile header fixes, card frame structure fix, and Style Manager palette timing fix.

Verification

• Built release zip with Node 22 via npm run zip.
• Installed the final zip on the WP 7.0-RC4 Studio site and verified 29 browser-visible Nova blocks use API v3 in the iframe editor.
• Verified server registry reports no Nova block type below API v3.
• Ran native Node tests, focused Jest tests, PHP syntax/contract checks, and Plugin Check.
