-## Zero Data Retention (ZDR) Organization Limitation
+## Zero Data Retention (ZDR) Usage
 
-> **Note:** Codex CLI does **not** currently support OpenAI organizations with [Zero Data Retention (ZDR)](https://platform.openai.com/docs/guides/your-data#zero-data-retention) enabled.
-
-If your OpenAI organization has Zero Data Retention enabled, you may encounter errors such as:
+Codex CLI **does** support OpenAI organizations with [Zero Data Retention (ZDR)](https://platform.openai.com/docs/guides/your-data#zero-data-retention) enabled. If your OpenAI organization has Zero Data Retention enabled and you still encounter errors such as:
 
 ```
 OpenAI rejected the request. Error details: Status: 400, Code: unsupported_parameter, Type: invalid_request_error, Message: 400 Previous response cannot be used for this organization due to Zero Data Retention.
 ```
 
-**Why?**
-
-- Codex CLI relies on the Responses API with `store:true` to enable internal reasoning steps.
-- As noted in the [docs](https://platform.openai.com/docs/guides/your-data#responses-api), the Responses API requires a 30-day retention period by default, or when the store parameter is set to true.
-- ZDR organizations cannot use `store:true`, so requests will fail.
-
-**What can I do?**
-
-- If you are part of a ZDR organization, Codex CLI will not work until support is added.
-- We are tracking this limitation and will update the documentation once support becomes available.
+You may need to upgrade to a more recent version with: `npm i -g @openai/codex@latest`
