Are Old Squarespace Templates Still Supported?
Yes. Squarespace version 7.0 sites keep working, keep receiving customer support, and Squarespace has announced no end-of-life date. Discontinued templates keep working too. What has stopped is expansion: no new 7.0 sites can be started from the template store, no new 7.0 templates are being made, and new feature development is 7.1-only. Squarespace's own wording is that updating to 7.1 is "optional".
Squarespace 7.0 support status at a glance
What "still supported" actually covers
Squarespace's position is stated in three places, and the three are consistent.
On help: "Yes. We'll continue to help you with your site and answer any questions you have." That is from the discontinued features guide, and it applies to discontinued templates as much as to discontinued blocks.
On bug fixes: "If bugs or issues arise with the feature, we'll fix them. However, discontinued features are no longer developed and won't be updated with any new options."
On priority — and this is the sentence worth quoting, because it is the most candid one Squarespace has published — the Brine troubleshooting guide opens: "Although we still support Squarespace version 7.0, fixing bugs or issues is a lower priority for us while we focus on our current platform, version 7.1."
So: supported, not developed, and second in the queue. That is a materially different position from deprecated, and it is the honest summary of where Squarespace 7.0 stands in 2026.
What has actually stopped for Squarespace 7.0
Four things, none of which affects an existing site's ability to run.
New 7.0 sites. The Help Center still links to a "version 7.0 template store". We checked that URL in August 2026 and every one of the 198 templates it returns is a version 7.1 design. There is no public route left to start a fresh trial on a 7.0 template. The one remaining exception is duplication: Squarespace documents that duplicating a 7.0 site "creates a new version 7.0 website with the same site content and an identical design", which is a copy rather than a new build.
New 7.0 templates. The last version 7.0 template family shipped years ago, and the last activity in the 7.0 catalogue has been retirements, not additions. The most recent was Jones in August 2023.
Feature development. Fluid Engine, auto-layouts, course pages, video pages, site-wide animations, nested product categories, 10,000-product stores — all 7.1 only. Nothing built since 7.1 launched has been back-ported.
Template switching, if you uninstall. Discontinued templates cannot be reinstalled. Squarespace: "Before you uninstall a template, ensure it isn't discontinued. If it's discontinued, you won't be able to reinstall it." Switching away is reversible; uninstalling is not.
The Squarespace 5 precedent
This is the strongest available evidence about what happens to a legacy Squarespace platform, and it is rarely cited.
Squarespace 5 launched in 2008. It has been closed to new sites for well over a decade. It is still online in 2026, still runs customer sites, and still has its own dedicated Help Center — Squarespace links to it from the footer of the current one, and from the current version-and-template guide, which tells users that "If a left panel doesn't appear when you log into your site, you may be using our legacy platform, Squarespace 5."
Squarespace 5 sites have outlived the entire lifespan of version 7.0 so far. That is the pattern: closed to new signups, kept running, kept supported, not developed. Version 7.0 is currently in the earlier stage of the same pattern.
None of that is a guarantee. It is precedent, which is the most anyone can honestly offer, and it points strongly against the idea that a 7.0 site needs migrating this year.
Are discontinued Squarespace templates still supported?
Yes, with one irreversible caveat.
Thirty-two version 7.0 templates have been retired, including the entire Marquee family, Encore, Lincoln, Bryler, Fulton, Jones, Taylor and eighteen pre-family templates such as Hudson, Atelier and Devlin. Squarespace's statement on all of them: "Your site will stay online, and you can continue to use and edit the template as you've always been able to."
It goes on to say a discontinued template "may receive our latest features and functionality, as well as fixes for any critical issue that may arise, but this is not guaranteed for every template we've retired." Read that as: probably fixed, not promised.
The caveat is the Template panel. Install other templates and preview them freely, but do not click Uninstall on a discontinued one, because there is no way back. The full roster with retirement dates is in the complete list of Squarespace 7.0 templates.
What would change this answer
Worth naming, so you are not relying on someone else's judgement indefinitely. Three signals would move version 7.0 from "supported" to "wind down", and none of them has appeared:
A published end-of-life date. Squarespace has given none. When platforms retire, they announce it with a date — Squarespace did exactly that for AMP support in February 2025 and for the Twitter block in April 2023.
Removal of the 7.0 template guides. All 22 family guides are still live and still being edited; most were last updated in April 2026, and the Aviator guide in February 2026. Documentation is maintained for platforms that are staying.
Removal of the update tool. As long as Design → Update to Version 7.1 exists, Squarespace is treating 7.0 sites as sites it expects to still be there.
If any of those changes, the calculation changes. Until then, the platform's own behaviour says 7.0 is being kept, not sunsetted.
So should you update to Squarespace 7.1?
Not on urgency grounds, because there is no urgency. Squarespace's update guide answers "Do I have to move to version 7.1?" with "No. Updating your site from version 7.0 to 7.1 is optional."
Update when you want something 7.1 has: Fluid Engine, more than 200 products on a store page, course or video pages, auto-layouts, site-wide animations. Update if your template is discontinued and you are uncomfortable with the reduced-priority position. Do not update because a blog post implied a deadline.
Two things to weigh before you do. The update is permanent — Squarespace: "After you click Publish update, you can't undo your changes or revert to version 7.0." And it has hard limits: 150 pages, 200 products per store page, and your Custom CSS arrives commented out.
The whole sequence is in the 7.0 to 7.1 upgrade guide, and if you are on Brine specifically, the Brine-to-7.1 feature map covers what each Brine capability becomes.
For scale: across 54 Squareko-built client sites measured in August 2026 (Playwright/Chromium lab test, cloud datacenter, unthrottled, single run per site), 53 of 54 run Squarespace 7.1. That reflects what we build now, not what Squarespace supports.
If your 7.0 site is working, the honest advice is to leave it alone and revisit the question when you next want a feature it cannot do. Where it becomes worth a conversation is when a discontinued 7.0 template is holding back a business that has outgrown it — that is usually a rebuild rather than a conversion, and a premium Squarespace 7.1 template is the cheapest starting point for one. Most 7.0 sites need neither this year.
FAQ
-
No. Squarespace has announced no end-of-life date for version 7.0. Existing 7.0 sites keep working and keep receiving customer support. What has stopped is new development: no new 7.0 sites from the template store, no new 7.0 templates, and new features released for 7.1 only.
-
No. Squarespace's own update guide answers this directly: "Updating your site from version 7.0 to 7.1 is optional." Update when you want a 7.1 feature — Fluid Engine, course pages, larger stores, auto-layouts — rather than because of a perceived deadline.
-
No. Squarespace states that "your site will stay online, and you can continue to use and edit the template as you've always been able to." A discontinued template may still receive fixes and features, though that is not guaranteed. The only irreversible action is uninstalling it.
-
Not from the template store. The URL Squarespace's Help Center gives for the version 7.0 template store now returns only 7.1 templates. You can still duplicate an existing 7.0 site, which Squarespace documents as creating "a new version 7.0 website with the same site content and an identical design".
-
Yes, at lower priority. The Brine troubleshooting guide states: "Although we still support Squarespace version 7.0, fixing bugs or issues is a lower priority for us while we focus on our current platform, version 7.1."
-
It launched in 2008, closed to new sites, and is still online and supported in 2026 with its own Help Center. It is the closest precedent for how Squarespace handles a legacy platform: closed to new signups, kept running, kept supported, not developed.
