== 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:2013-2486[]
//* Wireshark always manages to score tickets for Burning Man, Coachella, and SXSW while you end up working double shifts. (ws-buglink:0000[])

* "On-the-wire" packet lengths are limited to 65535 bytes. (ws-buglink:8808[], ws-buglink:9390)
* "Follow TCP Stream" shows only the first HTTP req+res. (ws-buglink:9044[])
* Files with pcap-ng Simple Packet Blocks can't be read. (ws-buglink:9200[])

=== New and Updated Features

The following features are new (or have been significantly updated)
since version 1.11.2:

* Qt port:

** The About dialog has been added
** The Capture Interfaces dialog has been added.
** The Decode As dialog has been added.
** Several SCTP dialogs have been added.
** The statistics tree (the backend for many Statistics and Telephony menu
items) dialog has been added.

The following features are new (or have been significantly updated)
since version 1.11.1:

* Mac OS X packaging has been improved.

The following features are new (or have been significantly updated)
since version 1.11.0:

* Dissector output may be encoded as UTF-8. This includes TShark output.

* Qt port:

** The Follow Stream dialog now supports packet and TCP stream selection.
** A Flow Graph (sequence diagram) dialog has been added.
** The main window now respects geometry preferences.


The following features are new (or have been significantly updated)
since version 1.10:

* Wireshark now uses the Qt application framework. The new UI should provide
  a significantly better user experience, particularly on Mac OS X and Windows.
* A more flexible, modular memory manger (wmem) has been added. It was available
  experimentally in 1.10 but is now mature and has mostly replaced the old API.
* Expert info is now filterable and now requires a new API.
* The Windows installer now uninstalls the previous version of Wireshark
  silently.  You can still run the uninstaller manually beforehand if you wish
  to run it interactively.
* The "Number" column shows related packets and protocol conversation spans
  (Qt only).
* When manipulating packets with editcap using the -C <choplen> and/or
  -s <snaplen> options, it is now possible to also adjust the original frame
  length using the -L option.
* You can now pass the -C <choplen> option to editcap multiple times, which
  allows you to chop bytes from the beginning of a packet as well as at the end
  of a packet in a single step.
* You can now specify an optional offset to the -C option for editcap, which
  allows you to start chopping from that offset instead of from the absolute
  packet beginning or end.
* "malformed" display filter has been renamed to "_ws.malformed".  A handful of
  other filters have been given the "_ws." prefix to note they are Wireshark
  application specific filters and not dissector filters.

=== Removed dissectors

* The ASN1 plugin has been removed as it's deemed obsolete.
* The GNM dissector has been removed as it was never used.

== Getting Wireshark

Wireshark source code and installation packages are available from
http://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 http://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.
