Wireshark 3.6.1

A new version of Wireshark has been released recently, Wireshark 3.6.1 with several fixes and new addons, and it’s a free open-source packet analyzer.

Wireshark is used for several purposes since Wireshark is one of the world’s most widely used network protocol analyzers. What about its compatibility? 

With individual downloads for 32-bit and 64-bit versions of the operating systems, the Wireshark network protocol analyzer is compatible with all the major platforms like:-

  • Windows
  • Linux
  • macOS

While Wireshark is primarily used for the following things:-

  • Analysis
  • Troubleshooting
  • Education 
  • Development

Wireshark 3.6.1 – What’s New?

In this latest release, only one new thing has been updated, and it’s:-

  • The ‘console.log.level’ preference was removed in Wireshark 3.6.0.

On the CLI that maps to the new logging subsystem, the -o console.log.level:’ backward-compatibilty option has been added in this new release. In near future, it will be removed by the foundation, since, it’s just a transition mechanism for users.

Vendor-supplied Packages

Since Linux and Unix vendors mostly supply their own Wireshark packages, so, one can use the package management system of Wireshark to install or upgrade the to the latest available version.

However, on the download page on the official website of Wireshark, a list of third-party packages is available, from which users can download according to their needs.

But, this new version of Wireshark has many features and it also fixed many bugs that we have mentioned above, so, users must update their Wireshark for better performance as soon as possible.

The new version can be downloaded from here.
