This is an experimental release intended to test new features for Wireshark 3.6.
2013-03-15 01:33:46 +00:00
== What is Wireshark?
2019-12-18 18:29:53 +00:00
Wireshark is the world’
It is used for troubleshooting, analysis, development and education.
2013-03-15 01:33:46 +00:00
2018-02-04 23:15:02 +00:00
== What’
2013-03-15 01:33:46 +00:00
2021-11-12 10:11:25 +00:00
* The PCRE2 library (https://www.pcre.org/) is now a required dependency to build Wireshark.
2021-12-14 23:47:30 +00:00
* A compiler with C11 support is required.
2021-11-12 10:11:25 +00:00
2019-12-18 18:29:53 +00:00
Many improvements have been made.
See the “New and Updated Features” section below for more details.

2013-03-15 01:33:46 +00:00
=== New and Updated Features
2021-11-19 02:36:37 +00:00
The following features are new (or have been significantly updated) since version 3.6.0:
2019-11-18 20:10:21 +00:00
2021-12-09 21:41:07 +00:00
* The Windows installers now ship with Npcap 1.60.
They previously shipped with Npcap 1.55.
2021-10-04 08:20:16 +00:00
2021-10-14 13:17:41 +00:00
* Display filter syntax:
2021-11-19 10:16:02 +00:00
** 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.
2021-11-19 02:36:37 +00:00
** 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.
2021-11-23 13:40:14 +00:00
** 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: \\, \', \".
2021-11-19 02:36:37 +00:00
** 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.
2021-12-13 01:06:01 +00:00
** Adds a new strict equality operator "===" or "all_eq". The expression "a === b" is true if and only if all a's are equal to b.
The negation of "===" can now be written as "!==" (any_ne), in adittion to "~=" (introduced in Wireshark 3.6.0).
2021-12-22 09:36:46 +00:00
** Adds the aliases "any_eq" for "==" and "all_ne" for "!=".
2021-10-26 22:28:54 +00:00
2021-10-28 10:07:35 +00:00
* 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.
2021-10-22 13:24:43 +00:00
* Mesh Connex (MCX) support in existing 802.11 packets.
2021-12-07 05:47:54 +00:00
* Capture Options dialog contains same configuration icon as Welcome Screen. It is possible to configure interface there.

=== New Protocol Support
2016-06-03 16:21:21 +00:00
2020-10-22 19:13:21 +00:00
// Add one protocol per line between the -- delimiters in the format
2021-11-19 02:36:37 +00:00
// “Full protocol name (Abbreviation)”
// git log --oneline --diff-filter=A --stat v3.7.0rc0.. epan/dissectors plugins
Switch from AsciiDoc to Asciidoctor.
Switch the markup text processor for files in the docbook directory from
AsciiDoc to Asciidoctor. Asciidoctor has several useful features (such
as direct PDF output) and is actively developed. It's written in Ruby
but that dependency can be sidestepped with AsciidoctorJ, a
self-contained bundle that only depends on the JRE.
The current toolchain targets require Python, AsciiDoc, DocBook XML,
DocBook XSL, Java, FOP, xsltproc, lynx, and the HTMLHelp compiler:
HTML: AsciiDoc → DocBook XML → xsltproc + DocBook XSL
Chunked HTML: AsciiDoc → DocBook XML → xsltproc + DocBook XSL
PDF: AsciiDoc → DocBook XML → xsltproc + DocBook XSL → FOP
HTMLHelp: AsciiDoc → DocBook XML → xsltproc + DocBook XSL → HHC
This change removes the AsciiDoc and FOP requirements and adds either
AsciidoctorJ or Asciidoctor + Ruby:
HTML: Asciidoctor → DocBook XML → xsltproc + DocBook XSL
Chunked HTML: Asciidoctor → DocBook XML → xsltproc + DocBook XSL
PDF: Asciidoctor
HTMLHelp: Asciidoctor → DocBook XML → xsltproc + DocBook XSL → HHC
Ideally we could generate all of these using AsciidoctorJ, Java, and
lynx. Unfortunately we're not there yet.
The release notes depend on several macros (ws-buglink, ws-salink,
cve-idlink, sort-and-group). Add Asciidoctor (Ruby) equivalents.
Remove the BUILD_xxx_GUIDES CMake options and add various output targets
automatically. This means that you have to build the various documentation
targets explicitly.

== Getting Wireshark
Wireshark source code and installation packages are available from
2014-09-17 00:15:56 +00:00
https://www.wireshark.org/download.html.
2013-03-15 01:33:46 +00:00
=== Vendor-supplied Packages
2020-09-15 20:56:25 +00:00
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
2021-10-07 03:53:17 +00:00
https://www.wireshark.org/download.html[download page]
2013-03-15 01:33:46 +00:00
on the Wireshark web site.
== File Locations
2020-09-15 20:56:25 +00:00
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries.
These locations vary from platform to platform.
2021-10-07 03:53:17 +00:00
You can use menu:Help[About Wireshark,Folders] or `tshark -G folders` to find the default locations on your system.
