Wireshark  1.9.0 Beta
* Wireshark on 32- and 64-bit Windows supports automatic updates.
* The main welcome screen and status bar now display file sizes using strict SI prefixes instead of old-style binary prefixes.
* It is now possible to compare two fields in a display filter (for example: udp.srcport != udp.dstport). The two fields must be of the same type for this to work.
