=== New and Updated Features

The following features are new (or have been significantly updated)
since version 1.99.0:

* Qt port:

** You can now show and hide toolbars and major widgets using the View menu.
** You can now set the time display format and precision.
** The byte view widget is much faster, particularly when selecting large
reassembled packets.
** The byte view is explorable. Hovering over it highlights the corresponding
field and shows a description in the status bar.
** An Italian translation has been added.
** The Summary dialog has been updated and renamed to Capture File Properties.
** The VoIP Calls and SIP Flows dialogs have been added.

The following features are new (or have been significantly updated)
since version 1.12.0:

(up from 100k).
* TShark now resets its state when changing files in ring-buffer mode.
* Expert Info severities can now be configured.
* Wireshark now supports external capture interfaces.  External capture
interfaces can be anything from a tcpdump-over-ssh pipe to a program that

available in the Qt UI yet.

== 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.
