# Release 5.2.1

A patch release with targeted fixes to AI Agent streaming, session handling, and JWT compliance.

#### AI Agent Chatbox

* **Fixed an SSE connection leak** that could cause HTTP connection saturation during long-lived chat sessions.
* **Streaming responses for the "Invoke AI agent"** node to are now correctly recognized as streaming buffered until completion.
* **Faster rendering of long conversations** in the AI Agent Chatbox: large JSON payloads inside collapsed function-call messages are no longer rendered until expanded.

#### Reliability

* **Initial Redis session TTL for async tasks raised from 5 to 240 minutes**, preventing occasional session-state loss during long-running async operations.

#### Standards compliance

* **JWT claims containing a datetime are now emitted as seconds since the Unix epoch**, conforming to RFC 7519. This fixes validation failures in strict OIDC/JWT clients.

#### Localization

* Improved French translation for pagination controls.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wem.io/platform/release-notes/runtime-release/release-5.2.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
