Version 6.2

 

·New wireless adapters supported (Windows Vista or 7 required): Intel 3945, 4965, 5100, 5150, 5300, 5350.

·UDP stream reconstruction.

·A few improvements in the protocol decoder.

 

Version 6.1

 

·New operating systems supported: Windows XP 64-bit Edition, Windows Vista 64-bit Edition, Windows Server 2008 32-bit and 64-bit Editions.

·Decreased RAM utilization in the VoIP analysis module. The new version can handle more simultaneous calls using less RAM.

·Adjustable jitter buffer for realistic simulation of real-live VoIP phone sound quality.

·Improved "Find" dialog: Search direction and Unicode search (UTF-8, UTF-16) are now supported.

·Noise level is now displayed on the "Channels" tab.

·More flexible decoder tree options: You can now set the number of nodes to be expanded.

·Many other improvements and bug fixes.

 

 

Version 6.0

 

·VoIP module for advanced in-depth analysis, recording, and playback of SIP and H.323 voice communications.

·Visual TCP session analysis that graphically displays session diagrams.

·Visual packet builder that facilitates packet construction in Packet Generator.

 

 

Version 5.7

 

·Support for 802.11n.

·Support for cards based on the latest Atheros chipsets.

·Signal level in dBm is now available in addition to signal level in percentile (Atheros-based cards).

·

 

Version 5.6

 

·Full IPv6 support throughout the application (decoding, filters, search, alarms).

·UTF-8 support in TCP session reconstruction.

·Optional reassembly of fragmented IP packets.

·A new alarm type: the application can pronounce messages using the Windows text-to-speech engine.

·A few improvements and configurable options related to decoding and session reconstruction.

·Fixed a resource leak under Windows Vista if the DPI value is set to 120 or higher.

 

 

Version 5.5

 

·Windows Vista support.

 

 

Version 5.4

 

·Support for CommView Remote Agent for WiFi.

 

 

Version 5.3

 

·IP-to-country mapping for IP addresses provides real-time geolocation for all IP addresses shown by the application.

·Redesigned columns in the "Packets" tab and "Log Viewer" to make them more convenient to use. The column order on all tabs of the main application window is now customizable.

·Ability to create any number of snapshots of the current packet buffer, which makes it much easier to work with packets under a heavy network load. You can now examine the buffer in separate windows, without the risk of losing old packets and the need to look for packets that were scrolled out of view.

·Colorization of Management frames depending on their type.

·Improved alarms allow you to easily detect Ad Hoc stations and send customizable e-mail alerts.

·Support for Intel PRO/Wireless 2200BG and 2915ABG adapters (beta version).

·Support for new 802.11a channels in the JP regulatory domain.

·Resizable "Statistics" window.

·Improved "Find" dialog.

·Optional gridlines for a better packet visibility.

·A few other improvements.

 

Version 5.2

 

·Quick Filters that allow you to easily create new packet views for similar packets based on MAC addresses, IP addresses, or ports.

·Encryption type identification.

·A new Node Reassociation tool that can help you re-initiate WPA-PSK key exchange.

·Support for new 802.11a European channels.

·Updated MAC vendor list.

·A new adapter is supported: TRENDnet TEW-501PC.

·Automatic application updates.

·Many other improvements.

 

Version 5.1

 

·Several new adapters are now supported: 3Com OfficeConnect Wireless a/b/g PC Card (3CRWE154A72), D-Link AirPlus G DWL-G630 Wireless Cardbus Adapter (Rev. C), D-Link AirPremier DWL-AG530 Wireless PCI Adapter, NETGEAR WG511U Double 108 Mbps Wireless PC Card.

·The driver has been updated to ensure compatibility with the latest revisions of a number of D-Link adapters.

·Minor bugs related to capture file import/export and protocol decoding have been fixed.

 

Version 5.0

 

·Proactive scanning using PROBE REQUEST packets (requires an adapter based on the Atheros chipset).

·Packet Generator is now available (requires an adapter based on the Atheros chipset).

·New advanced rules that allow the user to filter packets based on frame types, frame subtypes, retry, duration, etc.

·High resolution time stamping (up to microseconds).

·New, compact, open log format.

·Graphic matrices representing conversations between hosts.

·New decoding modules have been added: MS SQL, LDAP, and YMSG. SMB and ICQ decoding has been improved.
