This release had improvements in three areas:
1. Packet Generator. Mostly in the Packet Player (button is on lower right section of Packet Generator window) - it now saves the paths to recent packet captures you have played previously and there is now a status window. Be aware that once you start a playback you cannot stop it. TCP, UDP, ICMP, and RAW manual packet definition windows now show the length of the data portion of the payload and it now makes a definite check against the actual MTU of the sending interface.
2. SSL Certificate Scanner. The SSLv3 POODLE vulnerability issue is now addressed by showing you new columns with connection types SSLv2 through TLS 1.2. The server you are connecting to is tested to see if it accepts all types and the results are displayed in the new columns.
3. SNMP Core and Advanced have some changes including buttons to go between the two tools rapidly and improvements to the OID selector.
If you have an active maintenance plan you can click on Help/Check for New Version. The links to download the software are in the embedded IE window on the right side of the program. The installed version has a full installation and the USB version uses a patch.
