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

This is a semi-experimental release intended to test new features for
Wireshark 2.6.

== 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

* Display filter buttons can now be edited, disabled, and removed via a context
  menu directly from the toolbar

* Drag&Drop filter fields to the display filter toolbar or edit to create
  a button on the fly or apply the filter as a display filter.

* Application startup time has been reduced.

* The installation step for Wireshark will now install headers required to
  build plugins. A pkg-config file is provided to help with this
  (see doc/plugins.example for details). Note you must still rebuild all
  plugins between minor releases (X.Y).

//=== Bug Fixes

//The following bugs have been fixed:

//* ws-buglink:5000[]
//* ws-buglink:6000[Wireshark bug]
//* cve-idlink:2014-2486[]
//* Wireshark convinced you to switch seats on the plane while neglecting to tell you that its seat was noticeably moist.

//_Non-empty section placeholder._

=== New and Updated Features

The following features are new (or have been significantly updated)
since version 2.4.0:
* Add color support for TShark with --color option (non-Windows only).
* The "matches" display filter operator is now case-insensitive.
* Display expression (button) preferences have been converted to a UAT.
  This puts the display expressions in their own file.  Wireshark still
  supports preference files that contain the old preferences, but new
  preference files will be written without the old fields.
* SMI private enterprise numbers are now read from the "enterprises.tsv" configuration file.
* QUIC dissector is renamed to G(oogle) QUIC (quic => gquic).
* Selected packet number can now be shown in the Status Bar by enabling
  Preferences -> Appearance -> Layout -> Show selected packet number.
* File load time in Status Bar is now disabled by default and can be enabled in
  Preferences -> Appearance -> Layout -> Show file load time.
* Support for G.729 codec in the RTP Player (via the bcg729 library).
* Support for hardware-timestamping of packets
* Improved NetMon .cap support with comments, event tracing, network filter,
  network info types and some Message Analyzer exported types.
* Personal plugins folder on Linux/Unix is now ~/.local/lib/wireshark/plugins.
* Add Flow Graph functionality to TShark using -z
* Capinfos now prints SHA256 hashes in addition to RIPEMD160 and SHA1. MD5 output
  has been removed.
* Packet editor has been removed (GTK only experimental feature).

== 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.
