Release 5.2.1

Release data: 2026-05-21

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.
