Launched in 2014, Squarespace version 7.0 categorizes its 91 templates into certain template "families," which are groups of similarly coded templates alike in their basic structure and functionality. Each one has its specific rules and style options, so you may need to swap templates (and risk losing content) to access certain functionality. For example, infinite scroll is exclusive to the Farro and Skye template families, while only Wells and Five allow sidebars on all of their pages, not just blogs. Squarespace scrapped those hard-and-fast classifications with the release of version 7.1 in early 2020. All of its 140-plus templates now belong to the same family with the same underlying structure and design options, which makes it easier to change site styles in seconds. While neither version of Squarespace is conclusively "better" than the other, version 7.1 is more ideal for people who are new to the platform since it aggressively streamlines the design process, especially since the July 2022 rollout of Fluid Engine. That's Squarespace's next-gen content editor for 7.1 sites, which utilizes a grid system and additional block placement options for improved layout flexibility (particularly on mobile). Users who have built a Squarespace site before may still have good reason to stick with version 7.0 since its templates have some advanced style options that haven't been added to the new ones yet. (See: parallax scrolling, one especially popular feature of the beloved Brine template family that's missing from version 7.1; people were pretty salty about that one.) One caveat: Switching between versions 7.0 and 7.1 requires a full rebuild and can mess with your site's search ranking, so choose wisely. On the bright side, Squarespace offers a free 14-day trial so you can noodle around with both before you commit.
