• Fixes bug that was causing the app to filter out networks with an RSSI of -85 dBm or lower.
• New app icon (Thanks to Steven K.)
New in version 2.0:
• Fixes incorrect max. data rates under certain circumstances.
• Fixes incorrect state of Stop button when not scanning.
• Addresses issue caused by certain access points that advertise a secondary channel even though they are set to operate at 20 MHz channel width only.
• Addresses an issue where intermittent 0 dBm RSSI values might be reported by OS X for certain networks.
• Better looks in OS X Yosemite.
• Networks can be quickly filtered by ESSID, PHY mode, radio, vendor or signal strength levels.
• Networks can be grouped by physical radio in Signal Strength and Channels graph.
• Beacon interval and basic rates can now be added as columns.
• DFS channels can be hidden in Channels graph if not being used by any networks.
• Made sure CSV file generated from export option includes all fields.
• Vendors database can now be updated from within the app.
• Other minor bug fixes plus stability and performance improvements.
