A new version of Wireshark has been released recently by the Wireshark Team, it’s Wireshark 4.0.1, which contains several enhancements, new updates, and bug fixes.

Wireshark is one of the most widely used open-source free software packet analyzers that are currently available on the market, and it is available in a variety of options for different platforms.

There are many people who use Wireshark packet analyzers for the analysis of packets, not just network administrators only. As security analysts also use Wireshark packet analyzers for packet analysis purposes.
