= Wireshark {wireshark-version} Release Notes
// Asciidoctor Syntax Quick Reference:
// https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/
This is an experimental release intended to test new features for Wireshark 4.2.
== What is Wireshark?
Wireshark is the world’s most popular network protocol analyzer.
It is used for troubleshooting, analysis, development and education.
== What’s New
// Add a summary of major changes here.
// Add other changes to "New and Updated Features" below.
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.
The Windows build has a new SpeexDSP external dependency (https://www.speex.org).
The speex code that was previously bundled has been removed.
The personal extcap plugin folder location on Unix has been changed to
follow existing conventions for architecture-dependent files.
The extcap personal folder is now ``$HOME/.local/lib/wireshark/extcap``.
Previously it was ``$XDG_CONFIG_HOME/wireshark/extcap``.
The installation target no longer installs development headers by default.
That must be done explicitly using ``cmake --install <builddir> --component Development``.
The Wireshark installation is relocatable on Linux (and other ELF platforms
with support for relative RPATHs).
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:
* wsbuglink:18413[No Audio in RTP player with Wireshark 4.0.0] - RTP player do not play audio frequently on Win32 builds with Qt6
* wsbuglink:18510[Paused playback cannot continue to play] - Playback marker do not move after unpause with Qt6
//* wsbuglink:5000[]
//* wsbuglink:6000[Wireshark bug]
//* cveidlink:2014-2486[]
//* Wireshark grabs your ID at 3 am, goes to Waffle House, and insults people.
=== New and Updated Features
The following features are new (or have been significantly updated) since version 4.0.0:
// * The Windows installers now ship with Npcap 1.71.
// They previously shipped with Npcap 1.60.
* 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 field's raw data.
* Negation (unary minus) now works with any display filter arithmetic expression.
* ciscodump support Cisco IOS XE 17.x
* The default interval between GUI updates when capturing has been decreased
from 500ms to 100ms, and is now configurable.
* The *-n* option also now disables IP address geolocation information lookup
in configured MaxMind databases (and geolocation lookup can be enabled with
*-Ng*.) This is most relevant for tshark, where geolocation lookups are
synchronous.
// === Removed Features and Support

// === New File Format Decoding Support
// [commaize]

=== New Protocol Support
// Add one protocol per line between the -- delimiters in the format

of string values. By default it is off. Previously it was always on.
* The JSON dissector now supports "Display JSON in raw form".
* The IPv6 dissector has a new preference to show some semantic details
about addresses (default off).
* The XML dissector now supports display character according to the "encoding"

character encoding for some XML document without "encoding" attribute.
Too many other protocols have been updated to list them all here.

== Getting Wireshark
Wireshark source code and installation packages are available from
https://www.wireshark.org/download.html.
=== Vendor-supplied Packages
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
https://www.wireshark.org/download.html[download page]
on the Wireshark web site.
== File Locations
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries.
These locations vary from platform to platform.
You can use menu:Help[About Wireshark,Folders] or `tshark -G folders` to find the default locations on your system.
