= Wireshark wireshark-version:[] Release Notes
// AsciiDoc quick reference: http://powerman.name/doc/asciidoc

This is an experimental release intended to test new features for Wireshark 2.0.

== 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

//=== Bug Fixes

//The following bugs have been fixed:

//* ws-buglink:5000[]
//* ws-buglink:6000[Wireshark bug]
//* cve-idlink:2014-2486[]
//* Wireshark insists on calling you on your land line which is keeping you from abandoning it for cellular. (ws-buglink:0000[])

=== New and Updated Features

The following features are new (or have been significantly updated)
since version 1.12.0:

* The I/O Graph in the Gtk+ UI now supports an unlimited number of data points
(up from 100k).
* TShark now resets its state when changing files in ring-buffer mode.
* Expert Info severities can now be configured.
* Wireshark now supports external capture interfaces.  External capture
interfaces can be anything from a tcpdump-over-ssh pipe to a program that
captures from proprietary or non-standard hardware.  This functionality is not
available in the Qt UI yet.

* Qt port:

** The Qt UI is now the default (program name is wireshark).
** A Polish translation has been added.
** The Interfaces dialog has been added.
** The interface list is now updated when interfaces appear or disappear.
** The Conversations and Endpoints dialogs have been added.
** A Japanese translation has been added.
** It is now possible to manage remote capture interfaces.
** Windows: taskbar progress support has been added.
** Most toolbar actions are in place and work.
** More command line options are now supported

== 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#thirdparty[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 About→Folders to find the default
locations on your system.
