Wireshark 2.6.0 Release Notes

 This is the first release candidate for Wireshark 2.6.0.

 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

  Wireshark 2.6 is the last release that will support the legacy (GTK+)
  user interface. It will not be supported or available in Wireshark
  3.0.

  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:

   Dumpcap might not quit if Wireshark or TShark crashes. (Bug 1419[1])

  New and Updated Features

   The following features are new (or have been significantly updated)
   since version 2.5.0:

     • HTTP Request sequences are now supported.

     • Wireshark now supports MaxMind DB files. Support for GeoIP and
       GeoLite Legacy databases has been removed.

     • The Windows packages are now built using Microsoft Visual Studio
       2017.

     • The IP map feature (the “Map” button in the “Endpoints” dialog)
       has been removed.

   The following features are new (or have been significantly updated)
   since version 2.4.0:

     • 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.

     • Some keyboard shortcut mix-ups have been resolved by assigning
       new shortcuts to Edit → Copy methods.

     • TShark now supports color using the --color option.

     • 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.

     • The QUIC dissector has been renamed to Google QUIC (quic →
       gquic).

     • The selected packet number can now be shown in the Status Bar by
       enabling Preferences → Appearance → Layout → Show selected packet
       number.

     • File load time in the Status Bar is now disabled by default and
       can be enabled in Preferences → Appearance → Layout → Show file
       load time.

     • Support for the G.729A codec in the RTP Player is now added via
       the bcg729 library.

     • Support for hardware-timestamping of packets has been added.

     • Improved NetMon .cap support with comments, event tracing,
       network filter, network info types and some Message Analyzer
       exported types.

     • The personal plugins folder on Linux/Unix is now
       ~/.local/lib/wireshark/plugins.

     • TShark can print flow graphs using -z flow…

     • Capinfos now prints SHA256 hashes in addition to RIPEMD160 and
       SHA1. MD5 output has been removed.

     • The packet editor has been removed. (This was a GTK+ only
       experimental feature.)

     • Support BBC micro:bit Bluetooth profile

     • The Linux and UNIX 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).

     • The Windows installers and packages now ship with Qt 5.9.4.

     • The generic data dissector can now uncompress zlib compressed
       data.

     • DNS Stats now supports service level statistics.

     • DNS filters for retransmissions and unsolicited responses have
       been added.

     • The “tcptrace” TCP Stream graph now shows duplicate ACKS and zero
       window advertisements.

     • The membership operator now supports ranges, allowing display
       filters such as tcp.port in {4430..4434} to be expressed. See the
       User’s Guide, chapter Building display filter expressions for
       details.

 Getting Wireshark

  Wireshark source code and installation packages are available from
  https://www.wireshark.org/download.html[2].

  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 download page[3] 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.

 Known Problems

  The BER dissector might infinitely loop. (Bug 1516[4])

  Capture filters aren’t applied when capturing from named pipes. (Bug
  1814[5])

  Filtering tshark captures with read filters (-R) no longer works. (Bug
  2234[6])

  Application crash when changing real-time option. (Bug 4035[7])

  Wireshark and TShark will display incorrect delta times in some cases.
  (Bug 4985[8])

  Wireshark should let you work with multiple capture files. (Bug
  10488[9])

  Community support is available on Wireshark’s Q&A site[10] and on the
  wireshark-users mailing list. Subscription information and archives
  for all of Wireshark’s mailing lists can be found on the web site[11].
