Wireshark 4.1.0 Release Notes
This is an experimental release intended to test new features for
Wireshark 4.2.
What is Wireshark?
Wireshark is the worlds most popular network protocol analyzer. It is
used for troubleshooting, analysis, development and education.
Whats New
Wireshark is now better about generating valid UTF-8 output.
A new display filter feature for filtering raw bytes has been added.
Display filter autocomplete is smarter about not suggesting invalid
syntax.
Many other improvements have been made. See the “New and Updated
Features” section below for more details.
Bug Fixes
The following bugs have been fixed:
• Issue 18413[1] - RTP player do not play audio frequently on Win32
builds with Qt6
• Issue 18510[2] - Playback marker do not move after unpause with
Qt6
New and Updated Features
The following features are new (or have been significantly updated)
since version 4.0.0:
• The API has been updated to ensure that the dissection engine
produces valid UTF-8 strings.
• Wireshark now builds with Qt6 by default. To use Qt5 instead pass
USE_qt6=OFF to CMake.
• It is now possible to filter on raw packet data for any field by
using the syntax `@some.field == <bytes…>`. This can be useful
to filter on malformed UTF-8 strings, among other use cases where
it is necessary to look at the fields raw data.
New Protocol Support
DECT proprietary Mitel OMM/RFP Protocol (also named AaMiDe),
Management Component Transport Protocol (MCTP), Management Component
Transport Protocol - Control Protocol (MCTP CP), Non-volatile Memory
Express - Management Interface (NVMe-MI) over MCTP, SAP Enqueue

SAP Internet Graphic Server (SAP IGS), SAP Message Server (SAPMS),
SAP Network Interface (SAPNI), SAP Router (SAPROUTER), SAP Secure
Network Connection (SNC), Support for almost all WoW 1.12 messages
has been added., and World of Warcraft World (WOWW) display filters

Updated Protocol Support
• The JSON dissector now has a preference to enable/disable

it was always on.
Too many protocols have been updated to list here.
New and Updated Capture File Support

Most Linux and Unix vendors supply their own Wireshark packages. You
can usually install or upgrade Wireshark using the package management
system specific to that platform. A list of third-party packages can
be found on the download page[3] on the Wireshark web site.
File Locations
Wireshark and TShark look in several different locations for

locations on your system.
