= 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 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.
// === Bug Fixes
// The following bugs have been fixed:
//* wsbuglink:5000[]
//* wsbuglink:6000[Wireshark bug]
//* cveidlink:2014-2486[]
//* Wireshark keeps banging out random chords on your piano and yelling “LIPS LIKE SUGUAR, SUGAR KISSES” because it was funny that one time at a party.
=== 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, https://www.wireshark.org/docs/wsug_html_chunked/ChTelPlayingCalls.html[Playing VoIP Calls] and https://www.wireshark.org/docs/wsug_html_chunked/_rtp.html#ChTelRtpPlayer[RTP Player Window])
** 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
