Kubernetes Trace source: Introduced a beta feature for tracing in Kubernetes using the ed_k8s_trace node. This feature utilizes eBPF to monitor specified Kubernetes namespaces.
OTTL Transform Node: Released an ottl_transform node to beta. It can transform data items using OTTL statements.
Cisco ASA Format Support in Demo source node: Enhanced demo source to support Cisco ASA log formats, addressing common variants to improve compatibility.
Dynamic Pattern Location for grok and Regex filter nodes: Users can now specify locations for patterns within data items using pattern_field_path, enhancing pattern matching capabilities.

Halt Uploading Unused Diagnostic Health Data: Stopped the upload of redundant diagnostic health data to optimize resource usage.
Self Logs Upload Context Issue: Fixed a problem where the main context cancellation prevented self log uploads during agent shutdown by switching to a flush context.

Custom Installation Path Support: Unix-based systems can now set a custom installation path through the ED_INSTALL_PATH environment variable, increasing flexibility in deployments.
Removal of Preset Features Parameter: Simplified nodes by removing preset features, with default outputs now enabling all features unless otherwise specified.

Kubernetes Metric Enhancements: After a comprehensive inventory review, unused Kubernetes metrics were removed and missing metrics added to ensure a robust cluster summary.
OTLP Metric Category & Rollup Improvement: Introduced metric categorization in OTLP inputs for direct passthrough in roll-up services, streamlining metric management and discovery.
