### **What's New**

#### **1. User x DE Memory**

* DE can now store user-specific memory per DE instance.
* Memory is isolated:
  * Not shared across different users.
  * Not shared across different DEs (even for the same user).
* Memory can be added, recalled, and updated directly through regular conversation.
* Memory is retained for as long as the DE is active.

#### **2. Guardrails**

* Introduced both **Input Guardrails** and **Output Guardrails**.
* Supported capabilities:
  * Banned phrase detection
  * Pattern detection
  * Topic-based filtering
  * Prompt injection prevention
  * Custom validation rules support
* :warning: Guardrails can only be configured and used after the DE pipeline has been fully set up.
