Release Life Cycle

The Wireshark download page lists three types of releases: Stable, Old Stable, and Development.

  • The Stable release is the latest official version of Wireshark. In most cases this is the version you should use.
  • The Old Stable release is an older official version of Wireshark which is still supported. You may be required to use one of these, for example if your organization has strict software approval policies.
  • The Development version is used for testing new features. Use this if you need one of those features.

The Stable and Old Stable release lifetimes conform to the following guidelines:

  • At least two (and preferably exactly two) branches will be supported at any given time.

  • Each release shall be supported for a minimum of 18 months. Support might be extended to 24 or 30 months, e.g. for releases preceding a major change.

  • Support for release X.Y ends when it reaches the end of its minimum lifetime or when version X.Y+4 is released, whichever comes later.

Depending on the pacing of major releases and their lifetimes we might have an "Old Old Stable" branch in addition to the Stable and Old Stable ones.

See End of Life planning for life cycle information specific to each release.

A more detailed description can be found in the Release Policy.

End of Life planning

In order to limit the development burden, support for a (old-)stable release is eventually ended. This is the planning for abandoning old releases. A note is added why such release may still be relevant for you.

Discussion

Support for Windows 7 ended on January 14, 2020. Wireshark 3.2 is the last release that supports it.

Support for Windows Vista ended on April 11, 2017. Wireshark 2.2 is the last release that supports it.

Support for Windows XP ended on April 8, 2014. Wireshark 1.10 is the last release that supports it.

U3 reached end of life in 2009. We stopped producing U3 packages when 1.10 reached end of life.
