What's new in this version:

New and Updated Features:
- Experimental 32-bit and 64-bit Windows Installer (.msi) packages are available. It is recommended that you use these independently of the NSIS (.exe) installers. That is, you should make sure the NSIS package is completely uninstalled before installing the Windows Installer package and vice-versa
- Source packages are now compressed using xz instead of bzip2
- The legacy (GTK+) UI is disabled by default in the Windows installers
- The legacy (GTK+) UI is disabled by default in the development environment (Autotools and CMake)
- SS7 Point Codes can now be resolved into names with a hosts-like file
- Wireshark can now go fullscreen to have more room for packets
- TShark can now export objects like the other GUI interfaces
- Support for G.722 and G.726 codecs in the RTP Player (via the SpanDSP library)
- You can now choose the output device when playing RTP streams
- Added support for dissectors to include a unit name natively in their hf field. A field can now automatically append "seconds" or "ms" to its value without additional printf-style APIs
- The Default profile can now be reset to default values
- You can move back and forth in the selection history in the Qt UI
- IEEE 802.15.4 dissector now uses an UAT for decryption keys. The original decryption key preference has been obsoleted

- The (D)TLS Application Layer protocol (e.g. HTTP or CoAP) can now be changed via the Decode As dialog
- The RSA keys dialog for SSL keys has improved feedback for invalid settings and no longer requires the IP address, Port or Protocol fields to be set in addition to the Key File
- TCP Analysis will detect and flag more spurious retransmissions
