+## [1.1.3] - 2026-02-04
+
+### Added
+
+- **Network Retransmit Metrics**: TCP retransmit segment counting from `/proc/net/snmp` (Linux)
+  - Parses `RetransSegs` from the TCP section of `/proc/net/snmp`
+  - Provides visibility into network reliability and congestion issues
+- **Network Throughput Rate Calculation**: Real-time bytes sent/recv rate metrics in `GetSystemInfo()`
+  - Calculates `NetworkBytesSentRate` and `NetworkBytesRecvRate` using cached previous values
+  - Thread-safe rate tracking via `systemInfoCache` with mutex protection
+- **Container Name Detection**: New `getContainerName()` function for container identity
+  - Supports `CONTAINER_NAME`, Docker Compose (`COMPOSE_PROJECT_NAME` + `COMPOSE_SERVICE`)
+  - Kubernetes pod name via `POD_NAME` environment variable
+  - Docker container name via `DOCKER_CONTAINER_NAME`
+- **Container Image Detection**: New `getContainerImage()` function for container image tracking
+  - Supports `CONTAINER_IMAGE`, Kubernetes `POD_IMAGE`, and Docker `DOCKER_IMAGE` environment variables
+- **Memory Page Fault Metrics**: Page fault tracking from `/proc/vmstat` (Linux)
+  - Major page faults (`pgmajfault`) and minor page faults (derived from total `pgfault` - major)
+- **Disk IOPS Calculation**: Operations per second metric derived from disk I/O counters
+  - Calculates IOPS from total read/write operations and IO time
+- **System Call Counting**: Aggregate system call metrics from all processes (Linux)
+  - Reads from `/proc/[pid]/io` to count read (`syscr`) and write (`syscw`) system calls
