# Shopify deadlines calendar

> Every dated Shopify change that affects your store or apps, with days left, what to do and Shopify’s source. Subscribe to the calendar free, no email needed.

Every dated Shopify platform change we know of that affects merchants or their apps, in one list: what happens, how many days are left, who it affects and what to do. Each date links to Shopify's own page for it. The page is rebuilt every day, and the days left are counted from the date shown above the list. We checked every date on 8 November 2026.

## How to use the calendar

- **Start with the soonest date.** Each deadline says who it affects: merchants, Shopify Plus merchants or app developers. If it's yours, the "what to do" box says where to start.
- **Subscribe to the feed.** Add the calendar to Apple Calendar, Outlook or Google Calendar and new deadlines appear on their own, each with what to do and a link to Shopify's source. There's no sign-up and no email address to give.
- **Send the list to your app vendors.** Most of these dates land on apps rather than your theme. Send each vendor the deadlines that apply and ask for a written answer. If one can't meet a date, we can [build what you need as a custom Shopify app](https://thinkcommerce.com/services/shopify-app-development).
- **Read the background.** Our round-up of [Shopify Editions Fall '26 for UK brands](https://thinkcommerce.com/insights/shopify-editions-exponential) covers the developer deadlines alongside the rest of the release.

## How we keep it up to date

- **Shopify's own sources only.** Every date comes from shopify.dev, Shopify's help centre or the Shopify changelog, and links to it. If Shopify has announced a change without a date, it isn't listed until it has one.
- **Checked by hand.** Each deadline shows when we last checked it against its source. Shopify does move dates: it extended the end of Shopify Scripts to 30 June 2026.
- **Rebuilt every day.** The page and the feed are rebuilt every day, so the days left count down and passed deadlines move to the archive. The date above the list shows the day the count is from. We keep passed deadlines in the archive rather than delete them.
- **Missing a date?** If you know of a dated Shopify change that isn't here, [tell us about it](https://thinkcommerce.com/contact) and we'll check it against Shopify's sources.

## Get a theme and app audit before the next deadline

Most of these dates break things quietly: a widget stops loading, tracking stops firing or an app loses access to your data. We'll check every app and integration on your store against the dates above and fix what's at risk. [Talk to us about a theme and app audit](https://thinkcommerce.com/contact), or [compare our Shopify retainers](https://thinkcommerce.com/retainers) if you'd rather someone kept an eye on these dates for you.

## Frequently asked questions

### How often is the calendar updated?

The page and the calendar feed are rebuilt every day. The days left are counted from the date shown above the list. We add or change a deadline by hand when Shopify announces or moves a date, and each one shows when we last checked it.

### Do I need to give you an email address to subscribe?

No. The feed is a public file that your calendar app fetches like any web page. There is no sign-up, and nothing in the feed tracks you.

### Why isn't a date I've heard about on the list?

We only list dates we can find on Shopify's own pages, on shopify.dev, in the help centre or in the changelog. A change Shopify has announced without a date waits until it has one. If you know of a dated change we've missed, tell us through our contact page.

### Does every deadline affect my store?

No. Most only matter if an app or customisation still works the old way. Script tags, for example, only matter if an app still loads code into your storefront that way. The quickest check is to ask each app vendor in writing, or to ask us for a theme and app audit.

### Can I get a reminder before a deadline?

Yes, through your calendar app. Subscribe to the feed, then set an alert for all-day events in your calendar app's settings, such as a week before. The feed carries no alerts of its own, so it won't override yours.
