  It previously shipped with Qt 5.12.5.

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

* Automatic updates are supported on macOS.
* You can now select multiple packets in the packet list at the same time
** They can be exported as Text by “kbd:[Ctrl+C]” or “kbd:[Cmd+C]” and the corresponding
  menu in “menu:Edit[Copy > As ...]”
** They can be marked/unmarked or ignored/unignored at the same time
** They can be exported and printed using the corresponding menu entries
  “menu:File[Export Specified Packets]”, “menu:File[Export Packet Dissections]”
  and “menu:File[Print]”
* You can now follow HTTP/2 and QUIC streams.
* 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
** The "Expression..." toolbar entry has been moved to "menu:Analyze[Display filter Expression ...]" as well as to the context menu of the display filter toolbar
* Allow extcaps to be loaded from the personal configuration directory
* The Wireshark 3.1.0 Windows installers ship with Qt 5.12.6.
  Previous installers shipped with Qt 5.12.4.

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 (wsbuglink:15571[]).
* 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
  “menu:Tools[Credentials]” menu in Wireshark.
* Editcap can now split files on floating point intervals.
* Windows .msi packages are now https://support.microsoft.com/en-us/help/4472027/2019-sha-2-code-signing-support-requirement-for-windows-and-wsus[signed using SHA-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.
* Save RTP stream to .au supports any codec with 8000 Hz rate supported by Wireshark (shown in RTP player). If save of audio is not possible (unsupported codec or rate), silence of same length is saved and warning is shown.
* The “menu:Analyze[Apply as Filter]” and “menu: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.
* The Wireshark 3.1.0 Windows installers ship with Qt 5.12.4.
  Previous installers shipped with Qt 5.12.1.
