4.16.0 (Oct 2, 2025)

This release enhances user experience and system performance with improved visibility for unknown subscriber identifiers, refined analysis and monitoring capabilities, and strengthened system stability. Key updates include better detection of subscriber information, enhanced RADIUS failure signaling, and improved handling of SIP call flows. Security is bolstered with a hardened password policy and corrected CLI commands. Additionally, several bug fixes address false failure predictions and improve user session management, ensuring a more reliable and coherent experience.

🧭 User Interface & Experience

• AGL-37 Improved flow visibility for unknown subscriber identifiers – Flows missing IMSI/MSISDN/IMEI are now surfaced on the user interface with logical grouping with unknown-# , ensuring complete visibility in flow exploration.

🔍 Analysis & Monitoring

• AGL-81 RADIUS failure indication and model training – Enhanced failure signaling and model training for RADIUS-based analysis to improve classification accuracy.

• AGL-291 Layer 2 Diagnostics label improvements – Enhanced description labels in Layer 2 Diagnostics for clearer, more actionable insights.

• AGL-422 Enhanced subscriber info detection in User Plane – Better detection and attribution of subscriber information in user-plane analysis.

• AGL-443 Correct handling of “User Hung Up” indications – SIP BYE with “User Hung Up” is now treated as non-failure, reducing false failure flags in VoLTE analysis.

• AGL-423 Expanded Intent-Based Diagnostics test coverage for VoLTE short-code calls – Added an IMS test case to improve validation for short-code calling scenarios within Intent-Based Diagnostics.

⚙️ System Stability & Performance

• AGL-339 Managed NE types and domains in host mappings – Administrators can manage supported network element types and domains directly in host mappings, allowing them to add custom network element types and domains without requiring software releases.

🛡️ Security

• AGL-298 Password policy hardening – Addressed weak default password settings in the identity service to improve overall security posture.

• AGL-432 CLI reset command corrections for identity service – Fixed the reset command to operate safely and predictably during administrative recovery actions.

🐞 Bug Fixes

• AGL-118 Reliable SIP flow correlation with incomplete PCAPs – Improved handling of missing frames to maintain accurate SIP call flow correlation.

• AGL-296 Resolved false failures in mobile-to-mobile scenarios – Addressed analysis issues that could flag certain mobile-to-mobile calls as failed.

• AGL-342 Session timeout redirect – Users are now correctly redirected to the login page when their session token expires.

• AGL-393 Correct SOS APN categorization – The Network Planes card now correctly categorizes PDN Establishment events for the SOS APN.

• AGL-412 Reduced false failure predictions in IMS calls – Classifier adjustments prevent incorrect failure outcomes when calls are successful.

• AGL-425 Consistent Network Planes headers – Resolved header discrepancies for a more coherent experience across views.

• AGL-437 Resolved parser error impacting IMS classification – Fixed a parsing issue that could lead to generic parse-error classifications in IMS analysis.

• AGL-464 VoLTE announcement audio URI detection – Fixed detection of audio announcement URIs so announcements are correctly identified in VoLTE traces.
