AGILITY 4.28.0 Release Notes

User Interface & Experience

Packet Capture and Filtering

AGL-919 Wireshark display filters in Capture Insight - Added Wireshark display filter support in the Capture Insight view to streamline packet analysis and reduce time to isolate relevant traffic.
AGL-930 More reliable Wiregasm input filtering - Fixed an initialization issue that could cause infinite loading when using the input filter.

Analysis & Monitoring

Registration and Session Correlation

AGL-600 Improved SIP registration correlation - Enhanced correlation between SIP temporary registration and SIP registration flows for more complete end-to-end visibility.

4G/5G Connectivity Correlation

AGL-685 Improved temporal linking for SM flows - Refined temporal-based linking to improve session continuity and reduce fragmented flow views.
AGL-686 Improved temporal linking for SIP_REG flows - Updated temporal linking logic to increase correlation accuracy for registration-related traffic.
AGL-687 Improved temporal linking for MM flows - Improved temporal linking for mobility management flows to provide more consistent correlation across events.
AGL-911 Stability improvements for enhanced interface correlation - Fixed exceptions that could occur when enhanced interface data is empty, improving correlation robustness.

GTPv2 and PFCP Correlation

AGL-643 More consistent GTPv2/PFCP correlation - Improved correlation behavior when certain identifiers are missing, reducing gaps in cross-protocol session views.

Security

Security Posture Improvements

AGL-926 Security scan assessment follow-ups - Addressed outcomes from a security scan assessment to help strengthen the overall security posture.

Bug Fixes

Subscriber Experience

AGL-881 Subscriber view message completeness - Fixed an issue that could lead to missing messages in the Subscriber View.

Decoding and Protocol Handling

AGL-896 TLS session decoding reliability - Fixed a TLS session decoding issue in the user plane model to improve decoding accuracy and stability.
