## New features <a href="#new-features" id="new-features"></a>

### Integrations <a href="#integrations" id="integrations"></a>

#### Create a Knowledge Base via Flow <a href="#create-a-knowledge-base-via-flow" id="create-a-knowledge-base-via-flow"></a>

ZBrain Builder now allows users to create a Knowledge Base (KB) directly from an existing Flow, enabling seamless integration between workflow logic and enterprise knowledge management. This enhancement simplifies data ingestion by allowing users to use pre-built or custom Flows as structured knowledge sources, ensuring knowledge bases stay dynamically updated with the most relevant contextual data without manual data uploads.

**Navigation:**\
ZBrain Builder → Knowledge Base → Create -> Select Knowledge Source ->Import Data → Add via flows

**Key outcomes**

* Streamlines KB creation by allowing direct selection of data pipelines through Flows.
* Ensures reusability of existing automation Flows as dynamic data sources.
* Reduces setup time by eliminating manual data connection steps.

### **Agents** <a href="#agents" id="agents"></a>

#### Clear agent data toggle <a href="#clear-agent-data-toggle" id="clear-agent-data-toggle"></a>

ZBrain Builder introduces a **“Clear Agent Data”** toggle in the agent configuration panel, giving users full control over whether to retain or discard execution data for privacy, compliance, or lightweight operations. When enabled, this feature ensures no execution data (inputs, reports, or activity logs) is stored after an agent runs, providing greater flexibility and control over data retention policies.

**Navigation:**\
ZBrain → Login → Agent → Create New / Update Existing->Additional Settings

**Key outcomes**

* Enhances data privacy by preventing the storage of sensitive agent interaction data.
* Gives users control over data retention, allowing configuration per agent.
* Supports compliance needs where recording execution data is restricted.
* Reduces storage overhead by omitting unnecessary logs for transient tasks.
* Simplifies data management with clear visibility and messaging for non-recorded sessions.

#### Configure Apps with Agent Crew orchestration <a href="#configure-apps-with-agent-crew-orchestration" id="configure-apps-with-agent-crew-orchestration"></a>

ZBrain Builder now enables users to select **Agent Crew** as an orchestration method while creating a new app, empowering teams to design AI workflows where multiple specialized agents collaborate dynamically. This feature enables users to search for and select agent crews from a list, providing clear visibility into each crew’s name and the last updated timestamp. Once selected, users can delete selected agent crews before finalizing app setup via an intuitive “DELETE” icon.

**Navigation:**\
ZBrain → Apps → Create New App → Select Orchestration Method → Agent Crew → Configure Bot
