I'm proud to announce the release of Wireshark 4.1.0.


 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

  A Windows installer for Arm64 has been added.

  Windows installer file names now have the format
  Wireshark-<version>-<architecture>.exe.

  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.

  "Tools › MAC Address Blocks" can lookup a MAC address in the IEEE OUI
  registry.

  Some external configuration files have been compiled in for improved
  start-up times.

  The installation target no longer installs development headers by
  default.

  The Wireshark installation is relocatable on Linux (and other ELF
  platforms with support for relative RPATHs).

  Wireshark can be compiled on Windows using MSYS2[1]. Check the
  Developer’s guide for instructions.

  Wireshark can be cross-compiled for Windows using Linux. Check the
  Developer’s guide for instructions.

  Packet list sorting has been updated.

  "Tools › Browser (SSL Keylog)" can launch your web browser with the
  SSLKEYLOGFILE environment variable set to the appropriate value.

  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[2] - RTP player do not play audio frequently on
       Windows builds with Qt6.

     • Issue 18510[3] - Playback marker does not move after resume with
       Qt6.

  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 Qt 6.5.2. They previously
       shipped with Qt 6.2.3.

     • 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.

     • The "ciscodump" extcap supports 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.

     • The display filter drop-down list is now sorted by "most recently
       used" instead of "most recently created".

     • Display filter syntax-related changes:

        • 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.

        • Using the slice operator with strings produces a string.
       Previously it would produce a byte array. This is useful to
       index/slice UTF-8 multibyte strings. String byte slices can still
       be obtained using the "@" (raw operator) prefix.

        • Arithmetic expressions are allowed as set elements.

        • Absolute date and time values can be written as Unix time.

        • The limitation where a minus sign needed to be preceded by a
       space character has been removed.

        • Added XOR logical operator.

        • Fixed the implementation of `all …​ in` membership operator
       (#19188[4]).

        • The deprecated ~≃ operator symbol has been removed. It was
       replaced by !== in version 4.0.

     • Running the test suite requires the pytest[5] Python module. The
       emulation layer that allowed running tests without pytest
       installed has been removed.

     • When saving files or exporting packets after changing their time
       with the "Time Shift" dialog, the shifted time is written to the
       new file.

     • TLS secrets used in decrypting packets can be embedded (or
       discarded) from the capture file via the GUI, similar to the
       options --inject-secrets and --discard-all-secrets in editcap.

     • The text of any configured column (displayed or hidden) can be
       filtered anywhere that filters are used - in display filters,
       filters in taps, coloring rules, Wireshark read filters, and the
       -Y, -R, and -e options to tshark, the "Apply as Filter" GUI
       option, etc.

        • The filter field names are prefixed by "ws.col", followed by a
       lowercase version of the COL name found in epan/column-utils.h,
       e.g. "_ws.col.info" or "_ws.col.protocol"

        • Using the column names as a filter is slower than other filter
       types because the columns must be constructed, so when the same
       filtering can be achieved via other fields, prefer that.

     • The external name resolution text files "manuf", "enterprises"
       and "services" have been removed and replaced with static binary
       data. You can dump the respective internal data using `tshark -G
       manuf|enterprises|services`.

     • The Lua console dialogs under the Tools menu were refactored and
       redesigned. It now consists of a single dialog window for input
       and output.

     • Wireshark now shows byte units in the statistics in the
       user-selected language (uses the system default language by
       default).

     • Packet list sorting has been improved:

        • When sorting packet list with a filter applied, only the
       visible packets are sorted, which greatly increases sorting
       speed.

        • The cache size for column text is limited to a default of
       10000 rows, which limits the maximum memory usage. The maximum
       value can be changed in Preferences→Appearance→Layout

        • Due to the above, columns that require packet dissection can
       only be sorted if the number of visible rows is less than the
       cache size. If there are more rows visible, a warning will
       appear. Columns that do not require packet dissection (those that
       calculated directly from the capture file frame headers, such as
       packet number, time, and frame length) can be sorted with any
       number of visible rows.

        • Sorting can be interrupted.

     • When changing the dissector via the "Decode As" table for values
       that have default dissectors registered, selecting "(none)" will
       select no dissection (while still allowing heuristic dissectors
       to attempt to dissect.) The previous behavior was to reset the
       dissector to the default. To facilitate resetting the dissector,
       the default dissector is now sorted at the top of the list of
       possible dissector options.

     • 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 "init.lua" file is now loaded from any of the Lua plugin
       directories. Previously it was loaded from the personal
       configuration directory. (For backward-compatibility this is
       still allowed; note that deprecated features may be removed in a
       future release).

     • Installation of development headers must be done explicitly using
       the CMake command `cmake --install <builddir> --component
       Development`.

     • The Windows build has a new SpeexDSP external dependency
       (https://www.speex.org). The speex code that was previously
       bundled has been removed.

  Removed Features and Support

     • With the addition of the universal and consistent filtering
       support for column text, the previous support in the -e option to
       tshark for displaying column text via the column title has been
       removed in general. Those field names cannot be used elsewhere
       (as they may not be legal filter names) and create confusion if
       more than one column has the same title or if a column is
       renamed. Prefer the column format instead, e.g. "_ws.col.info"
       for "_ws.col.Info". However, for backwards compatibilty with
       existing tools and scripts, the titles of the default columns can
       continue to be used with "tshark -e" (but not elsewhere.)

     • The bundled script "dtd_gen.lua" that was disabled by default has
       been removed from the installation. It can be found in the
       Wireshark Wiki under "Contrib"[6].

  Updated Protocol Support

     • JSON: The dissector now has a preference to enable/disable
       "unescaping" of string values. By default it is off. Previously
       it was always on.

     • JSON: The dissector now supports "Display JSON in raw form".

     • IPv6: The dissector has a new preference to show some semantic
       details about addresses (default off).

     • IPv6: The dissector now supports dissecting Application-aware
       IPv6 Networking (APN6) option[7] in the Hop-by-Hop Options Header
       (HBH) and Destination Options Header (DOH). This feature supports
       to dissect all three types of APN ID, which are 32-bit, 64-bit
       and 128-bit in length.

     • XML: The dissector now supports display character according to
       the "encoding" attribute of the XML declaration, and has a new
       preference to set default character encoding for some XML
       document without "encoding" attribute.

     • SIP: The dissector now has a new preference to set default
       charset for displaying the body of SIP messages in raw text view.

     • HTTP: The dissector now supports dissecting chunked data in
       streaming reassembly mode. Subdissectors of HTTP can register
       itself in "streaming_content_type" subdissector table for
       enabling streaming reassembly mode while transferring in chunked
       encoding. This feature ensures the server stream messages of
       GRPC-Web over HTTP/1.1 can be dissected even if the last chunk is
       absent.

     • The media type dissector table now properly treats media types
       and subtypes as case-insensitive automatically, per RFC 6838.
       Media types no longer need to be lower cased before registering
       or looking up in the table.

     • CFM: The dissector has been overhauled and updated to the level
       of IEEE std 802.1Q-2022 and ITU-T Rec. G.8013/Y.1371 (08/2015).
       This includes dissection of additional PDU types and TLVs as well
       as deeper dissection of existing PDUs and TLVs.

   Too many other protocol updates have been made to list them all here.

  New and Updated Codec support

   Adaptive Multi-Rate (AMR), if compiled with opencore-amr[8]

  Major API Changes

     • Lua function "package.prepend_path" has been removed. If you need
       it please consider adding your own package.path customization
       code or installing your dependencies in Wireshark’s default
       paths.

     • The reassemble_streaming_data_and_call_subdissector() API has
       been added to provide a simpler way to reassemble the streaming
       data of a high level protocol that is not on top of TCP.

 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 download page[9] 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 "Help › About
  Wireshark › Folders" or `tshark -G folders` to find the default
  locations on your system.
