= 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
|
||
|
||
* The PCRE2 library (https://www.pcre.org/) is now a required dependency to build Wireshark.
|
||
|
||
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 insists on subscribing to two dozen streaming services but only watches three.
|
||
|
||
=== New and Updated Features
|
||
|
||
The following features are new (or have been significantly updated) since version 3.6.0:
|
||
|
||
* The Windows installers now ship with Npcap 1.60.
|
||
They previously shipped with Npcap 1.55.
|
||
|
||
* Display filter syntax:
|
||
** Set elements must be separated using a comma, e.g: {1, 2, "foo"}. Using only whitespace as separator was deprecated in 3.6 and is now a syntax error.
|
||
** Adds support for some additional character escape sequences in double quoted strings.
|
||
Besides octal and hex byte specification the following C escape sequences are now supported with the same meaning: \a, \b, \f, \n, \r, \t, \v.
|
||
Previously they were only supported with character constants.
|
||
** Unrecognized escape sequences are now treated as a syntax error. Previously they were treated as a literal character.
|
||
In addition to the sequences indicated above, backslash, single quotation and double quotation mark are also valid sequences: \\, \', \".
|
||
** The display filter engine now uses PCRE2 instead of GRegex (GLib bindings to the older end-of-life PCRE library).
|
||
PCRE2 is compatible with PCRE so the user-visible changes should be minimal.
|
||
Some exotic patterns may now be invalid and require rewriting.
|
||
|
||
* HTTP2 dissector now supports using fake headers to parse the DATAs of streams captured without first HEADERS frames of a long-lived stream (like
|
||
gRPC streaming call which allows sending many request or response messages in one HTTP2 stream). User can specify fake headers according to the
|
||
server port, stream id and direction of the long-lived stream that we start capturing packets after it is established.
|
||
|
||
* Mesh Connex (MCX) support in existing 802.11 packets.
|
||
|
||
* Capture Options dialog contains same configuration icon as Welcome Screen. It is possible to configure interface there.

== 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
|
||
https://www.wireshark.org/download.html[download page]
|
||
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 menu:Help[About Wireshark,Folders] or `tshark -G folders` to find the default locations on your system.
