= Wireshark wireshark-version:[] Release Notes
This is an experimental release intended to test new features for the next
stable release.
== 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[])
* "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[])
* MPLS-over-PPP isn't recognized. (ws-buglink:9492[])
=== 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.
* Qt port:
** 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 dialog has been added.
** A Japanese translation has been added.
** It is now possible to manage remote capture interfaces.
** Windows: taskbar progress support has been added.
The following features are new (or have been significantly updated)
since version 1.11.3:
* Transport name resolution is now disabled by default.
* Support has been added for all versions of the DCBx protocol.
* Cleanup of LLDP code, all dissected fields are now navigable.
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. It managed to swallow up the
User Specified Decodes dialog as well.
** The Export PDU 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 I/O Graph dialog has been added.
** French translation has updated.
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.
* 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.
* Expert information is now filterable when the new API is in use.
* 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.
* The Kerberos dissector has been replaced with an auto generated one from ASN1
protocol description, changing a lot of filter names.

=== Major API Changes
The libwireshark API has undergone some major changes:
* Many of the ep_ and se_ memory allocation routines have been removed.
* The (long-since-broken) Python bindings support has been removed from
Wireshark. If you want to write dissectors in something other than C,
use Lua.
== 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.
== Known Problems
