Wireshark 3.0 Changelog
Posted by Tom Ghyselinck, Last modified by Dieter Dobbelaere on 12 August 2019 11:06 AM

Excentis actively contributes to the Wireshark community to integrate the XRA-31 support and improve the DOCSIS protocol parser.

The results of these efforts are now available in the official release of Wireshark 3.0!

The Excentis version 3.0 of Wireshark is based on the official Wireshark 3.0 releases.
It enhances the well-known network analysis tool with pre-release enhancements and bug fixes for Excentis' XRA-31.
All these additional changes have already been integrated into the official Wireshark development version and will be part of a future official Wireshark release.
