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 worlds most popular network protocol analyzer. It is
used for troubleshooting, analysis, development and education.
Whats 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 1.50.
• 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.
• Display filter literal strings can now be specified using raw
string syntax, identical to raw strings in the Python programming
language. This is useful to avoid the complexity of using two
levels of character escapes with regular expressions.
• 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
Follow stream YAML output formats has been changed to add timestamps
and peers information (for more details see the users guide,
Following Protocol Streams[3])
IP fragments between public IPv4 addresses are now reassembled even
if they have different VLAN IDs. Reassembly of IP fragments where one
endpoint is a private (RFC 1918 section 3) or link-local (RFC 3927)
IPv4 address continues to take the VLAN ID into account, as those
addresses can be reused. To revert to the previous behavior and not
reassemble fragments with different VLAN IDs, turn on the "Enable
stricter conversation tracking heuristics" top level protocol
preference.
tshark can now export TLS session keys with the
--export-tls-session-keys option.
Wireshark participated in the Google Season of Docs 2020 and the
Users Guide has been extensively updated.

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[4] 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 About → Folders
to find the default locations on your system.
Getting Help
The Users Guide, manual pages and various other documentation can be
found at https://www.wireshark.org/docs/
Community support is available on Wiresharks Q&A site[5] and on the
wireshark-users mailing list. Subscription information and archives
for all of Wiresharks mailing lists can be found on the web site[6].
Bugs and feature requests can be reported on the issue tracker[7].
