Wireshark 3.6.0rc2 Release Notes

 This is the first release candidate 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 3.6.0rc1:

     • The display filter expression “a != b” now has the same meaning
       as “!(a == b)”.

   The following features are new (or have been significantly updated)
   since version 3.5.0:

     • Nothing of note.

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

     • The Windows installers now ship with Npcap 1.55.

     • A 64-bit Windows PortableApps package is now available.

     • A macOS Arm 64 (Apple Silicon) package is now available.

     • 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 libpcap 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 across all dialogs (Prepare Filter,
       Analyse, RTP Player …​)

     • Follow stream is now able to follow SIP calls based on their
       Call-ID value.

     • Follow stream YAML output format’s has been changed to add
       timestamps and peers information (for more details see the user’s
       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.

     • USB Link Layer reassembly has been added, which allows hardware
       captures to be analyzed at the same level as software captures.

     • 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
       User’s Guide has been extensively updated.

     • Format of export to CSV in RTP Stream Analysis dialog was
       slightly changed. First line of export contains names of columns
       as in other CSV exports.

     • Wireshark now supports the Turkish language.

     • The settings in the “Import from Hex Dump” dialog is now stored
       in a profile import_hexdump.json file.

     • Reload Lua plugins has been improved to properly support
       FileHandler.

     • Display filter syntax:

        • The expression “a != b” now always has the same meaning as
       “!(a == b)”. In particular this means filter expressions with
       multi-value fields like “ip.addr != 1.1.1.1” will work as
       expected (the result is the same as typing “ip.src != 1.1.1.1 and
       ip.dst != 1.1.1.1”). This avoids the contradiction (a == b and a
       != b) being true.

        • Use the syntax “a ~= b” or “a any_ne b” to recover the
       previous (inconsistent with ==) logic for not equal.

     • Corrected calculation of mean jitter in RTP Stream Analysis
       dialog and IAX2 Stram Analysis dialog

     • RTP streams are created based on Skinny protocol messages

     • The VoIP Calls Flow Sequence window shows more information about
       various Skinny messages
