=== New and Updated Features

The following features are new (or have been significantly updated)
since version 2.4.0:
* Add color support for TShark with --color option (non-Windows only)
* TCP Analysis will detect and flag more spurious retransmissions.
* 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.
* Support for user-editable "enterprises" file in the personal config dir (overriding system file).

specific to that platform. A list of third-party packages can be found
