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: * Conversation timestamps are supported for UDP/UDP-Lite protocols * 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. * Coloring rules, IO graphs, Filter Buttons and protocol preference tables can now be copied from other profiles using a button in the corresponding configuration dialogs. * APT-X has been renamed to aptX. * When importing from hex dump, it's now possible to add an ExportPDU header with a payload name. This calls the specific dissector directly without lower protocols. * sshdump and ciscodump can now use a proxy for the ssh connection. * Dumpcap now supports the `-a packets:NUM` and `-b packets:NUM` options. === 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.

Use the print function instead for debugging purposes. == 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].
