Wireshark 3.5.0 Release Notes

 This is an experimental release intended to test new features for
 Wireshark 3.6.

 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

  Many improvements have been made. See the “New and Updated Features”
  section below for more details.

  New and Updated Features

   The following features are new (or have been significantly updated)
   since version 3.4.0:

     • The Windows installers now ship with Npcap 1.31. They previously
       shipped with Npcap 1.20.

     • TCP conversations now support a completeness criteria, which
       facilitates the identification of TCP streams having any of
       opening or closing handshakes, a payload, in any combination. It
       is accessed with the new tcp.completeness filter.

     • Protobuf fields that are not serialized on the wire (missing in
       capture files) can now be displayed with default values by
       setting the new 'add_default_value' preference. The default
       values might be explicitly declared in 'proto2' files, or false
       for bools, first value for enums, zero for numeric types.

     • Wireshark now supports reading Event Tracing for Windows (ETW). A
       new extcap named ETW reader is created that now can open an etl
       file, convert all events in the file to DLT_ETW packets and write
       to a specified FIFO destination. Also, a new packet_etw dissector
       is created to dissect DLT_ETW packets so Wireshark can display
       the DLT_ETW packet header, its message and packet_etw dissector
       calls packet_mbim sub_dissector if its provider matches the MBIM
       provider GUID.

     • "Follow DCCP stream" feature to filter for and extract the
       contents of DCCP streams.

     • Wireshark now supports dissecting the rtp packet with OPUS
       payload.

     • Importing captures from text files is now also possible based on
       regular expressions. By specifying a regex capturing a single
       packet including capturing groups for relevant fields a textfile
       can be converted to a libcap capture file. Supported data
       encodings are plain-hexadecimal, -octal, -binary and base64. Also
       the timestamp format now allows the second-fractions to be placed
       anywhere in the timestamp and it will be stored with nanosecond
       instead of microsecond precision.

     • Significant RTP Player redesign and improvements (see Wireshark
       User Documentation, Playing VoIP Calls[1] and RTP Player
       Window[2])

     • RTP Player can play many streams in row

     • UI is more responsive

     • RTP Player maintains playlist, other tools can add/remove streams
       to it

     • Every stream can be muted or routed to L/R channel for replay

     • Save audio is moved from RTP Analysis to RTP Player. RTP Player
       saves what was played. RTP Player can save in multichannel .au or
       .wav.

     • RTP Player added to menu Telephony>RTP>RTP Player

   VoIP dialogs (VoIP Calls, RTP Streams, RTP Analysis, RTP Player, SIP
   Flows) are non-modal, can stay opened on background

     • Same tools are provided acros all dialogs (Prepare Filter,
       Analyse, RTP Player …​)

   Follow stream is now able to follow SIP call by SIP.Call-ID
