Wireshark 2.1.0 Release Notes
This is a semi-experimental release intended to test new features for
Wireshark 2.2.
__________________________________________________________________
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
New and Updated Features
The following features are new (or have been significantly updated)
since version 2.0.0:
* You can now switch between between Capture and File Format
dissection of the current capture file via the View menu in the Qt
GUI.
* You can now show selected packet bytes as ASCII, HTML, Image, ISO
8859-1, Raw, UTF-8, a C array, or YAML.
* You can now use regular expressions in Find Packet and in the
advanced preferences.
* Name resolution for packet capture now supports asynchronous DNS
lookups only. Therefore the "concurrent DNS resolution" preference
has been deprecated and is a no-op. To enable DNS name resolution
some build dependencies must be present (currently c-ares). If that
is not the case DNS name resolution will be disabled (but other
name resolution mechanisms, such as host files, are still
available).
* The byte under the mouse in the Packet Bytes pane is now
highlighted.
* TShark supports exporting PDUs via the -U flag.
* The Windows and OS X installers now come with the "sshdump" and
"ciscodump" extcap interfaces.
* Most dialogs in the Qt UI now save their size and positions.
* The Follow Stream dialog now supports UTF-16.
* The Firewall ACL Rules dialog has returned.
* The Flow (Sequence) Analysis dialog has been improved.
New File Format Decoding Support
Wireshark is able to display the format of some types of files (rather
than displaying the contents of those files). This is useful when
you're curious about, or debugging, a file and its format. To open a
capture file (such as PCAP) in this mode specify "MIME Files Format" as
the file's format in the Open File dialog.
New files that Wireshark can open in this mode include:
New Protocol Support
Apache Cassandra - CQL version 3.0, Bachmann bluecom Protocol,
Bluetooth Pseudoheader for BR/EDR, CISCO ERSPAN3 Marker, Edge Control
Protocol (ECP), Ericsson IPOS Kernel Packet Header Dissector Added
(IPOS), Extensible Control & Management Protocol (eCMP), FLEXRAY
Protocol dissector added (automotive bus), ISO 8583-1, ISO14443, ITU-T
G.7041/Y.1303 Generic Framing Procedure (GFP), LAT protocol (DECNET),
Metamako trailers, Nokia Intelligent Service Interface (ISI), Open
Mobile Alliance Lightweight Machine to Machine TLV payload Added (LwM2M
TLV), RTI TCP Transport Layer (RTITCP), STANAG 5602 SIMPLE, USB3 Vision
Protocol (USB machine vision cameras), USBIP Protocol, UserLog
Protocol, and Zigbee Protocol Clusters Dissectors Added (Closures
Lighting General Measurement & Sensing HVAC Security & Safety)
Updated Protocol Support
Bluetooth OBEX dissector (btobex) was renamed to Obex Dissector (obex),
allow to DecodeAs it over USB, TCP and UDP.
A preference was added to TCP dissector for handling IPFIX process
information. It has been disabled by default.
New and Updated Capture File Support
and Micropross mplog
New and Updated Capture Interfaces support
Non-empty section placeholder.
Major API Changes
The libwireshark API has undergone some major changes:
* The address macros (e.g., SET_ADDRESS) have been removed. Use the
(lower case) functions of the same names instead.
* "old style" dissector functions (that don't return number of bytes
used) have been replaced in name with the "new style" dissector
functions.
* tvb_get_string and tvb_get_stringz have been replaced with
tvb_get_string_enc and tvb_get_stringz_enc respectively.
__________________________________________________________________
Getting Wireshark
Wireshark source code and installation packages are available from
[1]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 [2]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.
