Sourced from@​reduxjs/toolkit's releases.

v2.9.2

Thisbugfix release fixes a potential internal data leak in SSR environments, improves handling of headers infetchBaseQuery, improvesretry handling for unexpected errors and request aborts, and fixes a longstanding issue withprefetch leaving an unused subscription. We've also shipped a newgraphqlRequestBaseQuery release with updated dependencies and better error handling.

Changelog

Internal Subscription Handling

We had a report that a Redux SSR app had internal subscription data showing up across different requests. After investigation, this was a bug introduced by the recentRTKQ perf optimizations, where the internal subscription fields were hoisted outside of the middleware setup and intocreateApi itself. This meant they existed outside of the per-store-instance lifecycle. We've reworked the logic to ensure the data is per-store again. We also fixed another issue that miscalculated when there was an active request while checking for cache entry cleanup.

Note that no actual app data was leaked in this case, just the internal subscription IDs that RTKQ uses in its own middleware to track the existence of subscriptions per cache entry.

fetchBaseQuery Headers

We've updatedfetchBaseQuery to avoid settingcontent-type in cases where a non-JSONifiable value likeFormData is being passed as the request body, so that the browser can set that content type itself. It also now sets theaccept header based on the selectedresponseHandler (JSON or text).

retry Behavior and Cleanup

Theretry util now respects themaxRetries option when catching unknown errors in addition to the existing known errors logic. It also now checks the request'sAbortSignal and will stop retrying if aborted.

In conjunction with that, dispatchingresetApiState will now abort all in-flight requests.

Theprefetch util andusePrefetch hook had a long-standing issue where they would create a subscription for a cache entry, but there was no way to clean up that subscription. This meant that the cache entry was effectively permanent. They now initiate the request without adding a subscription. This will fetch the cache entry and leave it in the store for thekeepUnusedDataFor period as intended, giving your app time to actually subscribe to the value (such as prefetching the cache entry in a route handler, and then subscribing in a component).

graphqlRequestBaseQuery

We've published@rtk-query/graphql-request-base-query v2.3.2, which updates thegraphql-request dep to ^7. We also fixed an issue where the error handling rethrew unknown errors - it now returns{error} as a base query is supposed to.

v2.9.1

Thisbugfix release fixes how sorted entity adapters handle duplicate IDs, tweaks the TS types for RTKQ query state cache entries to improve how thedata field is handled, and adds better cleanup for long-running listener middleware effects.

What's Changed

• fix(entityAdapter): ensure sorted addMany keeps first occurrence of duplicate ids by@​demyanm inreduxjs/redux-toolkit#5097
• fix(entityAdapter): ensure sorted setMany keeps just unique IDs in state.ids by@​demyanm inreduxjs/redux-toolkit#5107
• fix(types): ensure non-undefineddata on isSuccess withexactOptionalPropertyTypes by@​CO0Ki3 inreduxjs/redux-toolkit#5088
• Allow executing effects that have become unsubscribed to be canceled bylistenerMiddleware.clearListeners by@​chris-chambers inreduxjs/redux-toolkit#5102
