By default, Wireshark on Windows and macOS will check for new versions and notify you when they are available. If you have the Check for updates preference disabled or if you run Wireshark in an isolated environment you should subscribe to the wireshark-announce mailing list to be notified of new versions. See Section 1.6.5, “Mailing Lists” for details on subscribing to this list.
New versions of Wireshark are usually released every four to six weeks. Updating Wireshark is done the same way as installing it. Simply download and run the installer on Windows, or download and drag the application on macOS. A reboot is usually not required and all your personal settings will remain unchanged.
We offer two update channels, Stable and Development. The Stable channel is the default, and only installs packages from stable (even-numbered) release branches. The Development channel installs development and release candidate packages when they are available, and stable releases otherwise. To configure your release channel, go to → and search for “update.channel”. See Section 11.5, “Preferences” for details.
