 ## Overview
 
-Remix introduced support for "Single Fetch" ([RFC][rfc]) behind the [`future.unstable_singleFetch`][future-flags] flag in [`v2.9.0`][2.9.0] (stabilized as `future.v3_singleFetch` in [`v2.13.0`][2.13.0]) which allows you to opt-into this behavior. Single Fetch will be the default in [React Router v7][merging-remix-and-rr].
+Remix introduced support for "Single Fetch" ([RFC][rfc]) behind the [`future.unstable_singleFetch`][future-flags] flag in [`v2.9.0`][2.9.0] (later stabilized as `future.v3_singleFetch` in [`v2.13.0`][2.13.0]) which allows you to opt-into this behavior. Single Fetch will be the default in [React Router v7][merging-remix-and-rr].
 
 Enabling Single Fetch is intended to be low-effort up-front, and then allow you to adopt all breaking changes iteratively over time. You can start by applying the minimal required changes to [enable Single Fetch][start], then use the [migration guide][migration-guide] to make incremental changes in your application to ensure a smooth, non-breaking upgrade to [React Router v7][merging-remix-and-rr].

 ### Minor Changes
 
-- New `future.v3_singleFetch` flag ([#8773](https://github.com/remix-run/remix/pull/8773))
+- New `future.unstable_singleFetch` flag ([#8773](https://github.com/remix-run/remix/pull/8773))
 
   - Naked objects returned from loaders/actions are no longer automatically converted to JSON responses. They'll be streamed as-is via `turbo-stream` so `Date`'s will become `Date` through `useLoaderData()`
   - You can return naked objects with `Promise`'s without needing to use `defer()` - including nested `Promise`'s
