= Wireshark {wireshark-version} Release Notes
// AsciiDoc quick reference: http://powerman.name/doc/asciidoc
// Asciidoctor Syntax Quick Reference:
// http://asciidoctor.org/docs/asciidoc-syntax-quick-reference/
This is an experimental release intended to test new features for
Wireshark 3.0.
== 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
Many user interface 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 slowly leaked water under the kitchen sink over the course of several months, causing a big mess.
//_Non-empty section placeholder._
Dumpcap might not quit if Wireshark or TShark crashes.
(wsbuglink:1419[])
=== New and Updated Features
The following features are new (or have been significantly updated)
since version 2.6.0:
* TShark now supports the `-G elastic-mapping` option which generates an ElasticSearch mapping file.
* The “Capture Information” dialog has been added back (wsbuglink:12004[]).
* The Ethernet and IEEE 802.11 dissectors no longer validate the frame check sequence (checksum) by default.
* The TCP dissector gained a new “Reassemble out-of-order segments” preference
to fix dissection and decryption issues in case TCP segments are received
out-of-order. See the User’s Guide, chapter _TCP Reassembly_ for details.
* Decryption support for the new WireGuard dissector (wsbuglink:15011[], requires Libgcrypt 1.8).
* The BOOTP dissector has been renamed to DHCP. With the exception of
“bootp.dhcp”, the old “bootp.*” display filter fields are still supported
but may be removed in a future release.
* The SSL dissector has been renamed to TLS. As with BOOTP the old
“ssl.*” display filter fields are supported but may be removed in a
future release.
=== Removed Features and Support
* The legacy (GTK+) user interface has been removed and is no longer supported.
* Wireshark requires Qt 5.2 or later. Qt 4 is no longer supported.
* Wireshark requires GLib 2.32 or later.
* Building Wireshark requires CMake. Autotools is no longer supported.
* The tshark -z compare option was removed.
//=== Removed Dissectors
//=== New File Format Decoding Support
=== New Protocol Support
// Add one protocol per line between the -- delimiters.

== 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.
== Getting Help
The User’s Guide, manual pages and various other documentation can be
found at https://www.wireshark.org/docs/
Community support is available on https://ask.wireshark.org/[Wireshark’s
Q&A site] and on the wireshark-users mailing list. Subscription
information and archives for all of Wireshark’s mailing lists can be
found on https://www.wireshark.org/lists/[the web site].
Bugs and feature requests can be reported on
https://bugs.wireshark.org/[the bug tracker].
