= 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

//=== 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)
* TCP Analysis will detect and flag more spurious retransmissions.
* 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.
* Support for user-editable "enterprises" file in the personal config dir (overriding system file).

//=== Removed Dissectors

== 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.
