Wireshark  1.5.1 Beta
# Bug Fixes
* Wireshark is unresponsive when capturing from named pipes on Windows. (Bug 1759)
* Ring buffers are no longer turned on by default when using multiple capture files.
# New and Updated Features
* Wireshark can import text dumps, similar to text2pcap.
* You can now view Wireshark's dissector tables (for example the TCP port to dissector mappings) from the main window.
* TShark can show a specific occurrence of a field when using '-T fields'.
* Custom columns can show a specific occurrence of a field.
* You can hide columns in the packet list.
* Wireshark can now export SMB objects.
* dftest and randpkt now have manual pages.
* TShark can now display iSCSI service response times.
* Dumpcap can now save files with a user-specified group id.
* Syntax checking is done for capture filters.
* You can display the compiled BPF code for capture filters in the Capture Options dialog.
* You can now navigate backwards and forwards through TCP and UDP sessions using Ctrl+, and Ctrl+. .
* Packet length is (finally) a default column.
* TCP window size is now avaiable both scaled and unscaled. A TCP window scaling graph is available in the GUI.
* 802.1q VLAN tags are now shown by the Ethernet II dissector.
* Various dissectors now display some UTF-16 strings as proper Unicode including the DCE/RPC and SMB dissectors.
* The RTP player now has an option to show the time of day in the graph in addition to the seconds since beginning of capture.
* The RTP player now shows why media interruptions occur.
* Graphs now save as PNG images by default.
* TShark can read and write host name information from and to pcapng-formatted files. Wireshark can read it. TShark can dump host name information via [-z hosts].
* The tshark -z option now uses the [-z <proto>,srt] syntax instead of [-z <proto>,rtt] for all protocols that support service response time statistics. This syntax now matches Wireshark's syntax for this option.
