Spectra Pro Legacy is for existing sites built with the Spectra block library. Existing blocks, pages, settings, and content continue to work without migration or configuration changes. The Legacy add-on receives security and compatibility updates and support, while new features are developed in the separate Spectra Blocks plugin.

Blocks and tools in the Legacy library

• Core: Container, Heading, Image, Icon, Buttons, Info Box, Call To Action, and Countdown.
• Content: Sliders, Content Timeline, Google Maps, Inline Notices, Tabs, Taxonomy List, and Price List.
• Posts: Counter, Modal Popup, Post Carousel, Post Grid, and Post Timeline.
• Social: Instagram Feed, Blockquote, Social Share, Team, and Testimonials.
• Forms: Contact forms, newsletter signup, suggestion forms, and reCAPTCHA.
• SEO: FAQ, How-To, Review, and Table of Contents blocks.
• Dynamic content: Archive feed filtering by date, author, category, and post type.

Spectra Pro Legacy includes Loop Builder functionality within the Price List block, along with registration and login form options. The other form capabilities remain part of the library.

Site styling and the AI block

Site tools include Popup Builder, Coming Soon mode, block animations, local Google Fonts, and global styling defaults. The AI block is now called ZipAI and continues to work in Spectra Legacy for compatibility. New AI functions are being developed in Spectra Blocks.

How Spectra Blocks fits

Spectra Blocks is a separate plugin for new features and new installs. Installing it is optional, with no required migration or deadline. Both extensions can execute on the same site: existing pages continue using Legacy blocks while you create new pages with Spectra Blocks.

Compatibility and installation

Spectra Legacy works with most standard WordPress themes, including Spectra One, Astra, Blocksy, and GeneratePress. It is compatible with common plugins such as WooCommerce, SureCart, Gravity Forms, LearnDash, MemberPress, and Yoast SEO.

Install Spectra Legacy on the WordPress website that uses its blocks, then continue editing existing pages in the block editor. Existing settings and layouts remain in place.
