Spectra Legacy vs. Spectra Blocks
We’ve split Spectra into two products.
Spectra Legacy is this plugin — built for existing Spectra users. It receives security and compatibility updates and full support, but no new features. Spectra Blocks is a new, separate plugin where all new feature development happens, aimed at new installs and anyone who wants ongoing additions. If you’re already using this plugin, no action is needed; installing Spectra Blocks is entirely optional whenever you’re ready.
If you’re already using this plugin, you don’t need to do anything. If you want new features as they’re released, you can install Spectra Blocks separately, whenever you’re ready. There’s no deadline and no required migration.
