Wireshark 3.1.1 Release Notes

 This is an experimental release intended to test new features for
 Wireshark 3.2.

 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

  Many improvements have been made. See the “New and Updated Features”
  section below for more details.

  New and Updated Features

   The following features are new (or have been significantly updated)
   since version 3.1.0:

     • You can once again mark and unmark packets using the middle mouse
       button. This feature went missing around 2009 or so.

     • The Windows packages are now built using Microsoft Visual Studio
       2019.

     • IOGraph automatically adds a graph for the selected display
       filter if no previous graph exists

     • Action buttons for the display filter bar may be aligned left via
       the context menu

     • Allow extcaps to be loaded from the personal configuration
       directory

   The following features are new (or have been significantly updated)
   since version 3.0.0:

     • You can drag and drop a field to a column header to create a
       column for that field, or to the display filter input to create a
       display filter. If a display filter is applied, the new filter
       can be added using the same rules as “Apply Filter”

     • You can drag and drop a column entry to the display filter to
       create a filter for it.

     • You can import profiles from a .zip archive or an existing
       directory.

     • Dark mode support on macOS and dark theme support on other
       platforms has been improved.

     • Brotli decompression support in HTTP/HTTP2 (requires the brotli
       library).

     • The build system now checks for a SpeexDSP system library
       installation. The bundled Speex resampler code is still provided
       as a fallback.

     • WireGuard decryption can now be enabled through keys embedded in
       a pcapng in addition to the existing key log preference (Bug
       15571[1]).

     • A new tap for extracting credentials from the capture file has
       been added. It can be accessed through the -z credentials option
       in tshark or from the “Tools” menu in Wireshark.

     • Editcap can now split files on floating point intervals.

     • Windows .msi packages are now signed using SHA-2[2]. .exe
       installers are still dual-signed using SHA-1 and SHA-2.

     • The “Enabled Protocols” Dialog now only enables, disables and
       inverts protocols based on the set filter selection. The protocol
       type (standard or heuristic) may also be choosen as a filter
       value.

     • The “Analyze → Apply as Filter” and “Analyze → Prepare a Filter”
       packet list and detail popup menus now show a preview of their
       respective filters.

     • Protobuf files (*.proto) can now be configured to enable more
       precise parsing of serialized Protobuf data (such as gRPC).

     • HTTP2 support streaming mode reassembly. To use this feature,
       subdissectors can register itself to "streaming_content_type"
       dissector table and return pinfo→desegment_len and
       pinfo→desegment_offset to tell HTTP2 when to start and how many
       additional bytes requires when next called.

     • The message of stream gRPC method can now be parsed with
       supporting of HTTP2 streaming mode reassembly feature.

 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.
