# Sunsetting Flex sections developer preview

We've closed the Flex sections developer preview as of July 14th. This preview included theme blocks and style settings.

Theme blocks are now available to all theme developers. You can start using theme blocks immediately to create reusable modules for structuring content within sections. Learn more about [theme blocks](https://shopify.dev/docs/storefronts/themes/architecture/blocks/theme-blocks) in our documentation.

Style settings are no longer supported as we plan to explore different approaches in the future. You can remove any references to style settings from your development stores.
