New and Updated Features

In this latest release, Here below we have mentioned all the new and updated features:-

  • The macOS packages now ship with Qt 6.2.4 and require macOS 10.14. They previously shipped with Qt 5.15.3.
  • The Windows installers now ship with Npcap 1.71. They previously shipped with Npcap 1.70.
  • The Windows installers now ship with Npcap 1.70. They previously shipped with Npcap 1.60.
  • The ‘v’ (lower case) and ‘V’ (upper case) switches have been swapped for editcap and mergecap to match the other command line utilities.
  • The ip.flags field is now only the three high bits, not the full byte. Display filters and Coloring rules using the field will need to be adjusted.
  • New address type AT_NUMERIC allows simple numeric addresses for protocols which do not have a more common-style address approach, analog to AT_STRINGZ.
  • The Conversation and Endpoint dialogs have been redesigned.
  • The Windows installers now ship with Qt 6.2.3. They previously shipped with Qt 6.2.4.
  • The Windows installers now ship with Npcap 1.60. They previously shipped with Npcap 1.55.
  • The Windows installers now ship with Qt 6.2.4. They previously shipped with Qt 5.12.2.
  • The display filter syntax has been updated and enhanced.The default main window layout has been changed so that the Packet Detail and Packet Bytes are side by side underneath the Packet List pane.
  • The HTTP2 dissector now supports using fake headers to parse the DATAs of streams captured without first HEADERS frames of a long-lived stream (such as a gRPC streaming call which allows sending many request or response messages in one HTTP2 stream). Users can specify fake headers using an existing stream’s server port, stream id and direction.
  • The IEEE 802.11 dissector supports Mesh Connex (MCX).
  • The “Capture Options” dialog contains the same configuration icon as the Welcome Screen. It is now possible to configure interfaces there.
  • The “Extcap” dialog remembers password items during runtime, which makes it possible to run extcaps multiple times in row without having to reenter the password each time. Passwords are never stored on disk.
  • It is possible to set extcap passwords in tshark and other CLI tools.
  • The extcap configuration dialog now supports and remembers empty strings. There are new buttons to reset values back to their defaults.
  • Support to display JSON mapping for Protobuf message has been added.
  • macOS debugging symbols are now shipped in separate packages, similar to Windows packages.
  • In the ZigBee ZCL Messaging dissector the zbee_zcl_se.msg.msg_ctrl.depreciated field has been renamed to zbee_zcl_se.msg.msg_ctrl.deprecated
  • The interface list on the welcome page sorts active interfaces first and only displays sparklines for active interfaces. Additionally, the interfaces can now be hidden and shown via the context menu in the interface list
  • The Event Tracing for Windows (ETW) file reader now supports displaying IP packets from an event trace logfile or an event trace live session.
  • ciscodump now supports IOS, IOS-XE and ASA remote capturing.
  • The PCRE2 library is now required to build Wireshark.
  • You must now have a compiler with C11 support in order to build Wireshark.

Wireshark users should update their version as soon as possible in order to take advantage of better performance and results.
