 ### Core Capabilities
 - **Pipeline Architecture**: Independent processing pipelines with source(s) → filter → format → sink(s) flow
-- **Multiple Input Sources**: Directory monitoring, stdin, HTTP, TCP
-- **Flexible Output Sinks**: Console, file, HTTP SSE, TCP streaming, HTTP/TCP forwarding
+- **Multiple Input Sources**: File monitoring, console (stdin), random log generation, null
+- **Flexible Output Sinks**: Console, file, HTTP SSE, TCP streaming, null
 - **Real-time Processing**: Sub-millisecond latency with configurable buffering
 - **Hot Configuration Reload**: Update pipelines without service restart
+- **Session Management**: Built-in session tracking for multiple client connections
 
 ### Data Processing
 - **Pattern-based Filtering**: Chainable include/exclude filters with regex support
-- **Multiple Formatters**: Raw, JSON, and template-based text formatting
+- **Multiple Formatters**: Raw, JSON, and text formatting with integrated sanitizer policies
 - **Rate Limiting**: Pipeline rate controls
+- **Heartbeat Generation**: Flow-level heartbeat events for keep-alives
 
 ### Security & Reliability  
-- **Authentication**: mTLS support
-- **Access Control**: IP whitelisting/blacklisting, connection limits
-- **TLS Encryption**: Full TLS 1.2/1.3 support for HTTP connections
-- **Automatic Reconnection**: Resilient client connections with exponential backoff
 - **File Rotation**: Size-based rotation with retention policies
-
-### Operational Features
 - **Status Monitoring**: Real-time statistics and health endpoints
 - **Signal Handling**: Graceful shutdown and configuration reload via signals
 - **Background Mode**: Daemon operation with proper signal handling
