App Platform Deadlines 2026–2027: One Calendar
Choose what you want to explore
Store rules and framework support windows keep moving, and the dates sit on a dozen different pages. This is one calendar. Each row links to a guide that quotes the official source and names the page, so you can check it yourself. All pages were fetched on October 9, 2026. Dates on official pages can change, so confirm the linked page before you plan around a day.

Not a date, but a rule
React Native 0.82 and Expo SDK 55 run only on the New Architecture, so apps still on the legacy architecture have to migrate before moving to those versions. See the React Native New Architecture guide, which cites the React Native blog and the Expo docs.
Rails 8.2 has no announced release date on the pages we checked, so it is not in the calendar. The Rails 8.2 guide shows what the sources say today.
How to use this
Pick the rows that match your stack, open the linked guide and check the official source on the day you plan the work. If a date has passed and your app has not moved, that row is already your next task.
If you want an engineer to take care of these deadlines, see App care, or tell us about the app that is stuck.
