Download Wireshark 3.4.0

Version 3.4.0 of the open source protocol analyzer and packetniffer Wireshark has been released, a development version. With this program, various data packets and network protocols on the network can be analyzed. The program can also use previously saved data traffic as input. Wireshark runs on Windows, Linux, and macOS, with separate downloads for 32bit and 64bit versions of the operating systems. The changelog for this release shows the following changes and improvements:

The following features are new (or have been significantly updated) since version 3.3.1:

• The Protobuf fields defined as google.protobuf.Timestamp type of Protobuf standard library can now be dissected as Wireshark fields of absolute time type.

The following features are new (or have been significantly updated) since version 3.3.0:

• The Windows installers now ship with Npcap 1.00. They previously shipped with Npcap 0.9997.
• The Windows installers now ship with Qt 5.15.1. They previously shipped with Qt 5.12.8.

The following features are new (or have been significantly updated) since version 3.2.0:

• Windows executables and installers are now signed using SHA-2 only.
• Save RTP stream to .au supports any codec with 8000 Hz rate supported by Wireshark (shown in RTP player). If save of audio is not possible (unsupported codec or rate), silence of same length is saved and warning is shown.
• Asynchronous DNS resolution is always enabled. As a result, the c-ares library is now a required dependency.
• Protobuf fields can be dissected as Wireshark (header) fields that allows user input the full names of Protobuf fields or messages in Filter toolbar for searching.
• Dissectors based on Protobuf can register themselves to a new ‘protobuf_field’ dissector table, which is keyed with the full names of fields, for further parsing fields of BYTES or STRING type.
• Wireshark is able to decode, play, and save iLBC payload on platforms where the iLBC library are available.
• Wireshark is able to decode, play, and save opus payload on platforms where the opus library are available.
• “Decode As” entries can now be copied from other profiles using a button in the dialog.
• sshdump can now be copied to multiple instances. Each instance will show up a different interface and will have its own profile.
• The main window now supports a packet diagram view, which shows each packet as a textbook-style diagram.
• Filter buttons (“Preferences → Filter Buttons”) can be grouped by using “//” as a path separator in the filter button label.
• IPP Over USB packets can now be dissected and displayed
