         2004-??-??      Michael Lauer   <mickey@Vanille.de>
 
+        * Added command line option "-nocheck" to skip non-root and dhcp tests
         * Improved the speed reading the manufacturer list
         * GPS coordinates are now presented in the DMS (as opposed to decimal) format
 
         2003-12-18      Michael Lauer   <mickey@Vanille.de>
 
         * Released as Version 1.0.2 (Development Snapshot)
         * Added automatic uploading of capture files to "The Capture Dump" site at
           http://www.Vanille.de/projects/capturedump.spy
         * Initial reading of the manufacturer database happens now in background
         * Removed deprecated setMonitorMode() API ==> Use setMode( "monitor" ) now.
           The monitor mode now tries to use the standard IW_MODE_MONITOR first. If that
           doesn't work, it falls back to using the proprietary iwpriv commands
 
         2003-11-30      Michael Lauer   <mickey@Vanille.de>
 
         * Released as Version 1.0.1 (Development Snapshot)
         * Fixed ARP decoding for wired networks.
           Interestingly, 802.11 encapsulates these in IP packets, while wired ethernet just tags the type_of_protocol.
         * Added reading GPS data from a gps daemon.
         * Started preparations for utilizing Wellenreiter II in wired networks.
         * Implemented persistant configuration interface and retriggerable auto detection.
         * Added QCOP interface for talking to opie-networksettings.
         * Added parsing of DHCP packets and detecting DHCP servers.
         * Overhauled the configuration window and started with the customizable event system.
         * Added disabling the screensaver.
         * Added automatic opening and scrolling to the network tree if a new station appears.
 
         2003-05-10      Michael Lauer   <mickey@Vanille.de>
 
         * Released as Version 1.0 (Stable)
         * Added restarting the dhcp client if having killed it before.
         * Decouple dump files from live capture to shift control over 'what' is dumped to applications.
 
         2003-05-05      Michael Lauer   <mickey@Vanille.de>
 
         * Released as Version 1.0-RC1 (Release Candidate)
         * Fixed rare segfaults while sniffing and operating the GUI simultaenously.
         * Parse more data packets and detect more participating stations.
         * Added live graph window showing the signal strength on all channels.
         * Added parsing ARP packets and identifying IP addresses of participating stations.
         * Added parsing with optionally enabled PRISM headers (signal strength).
 
         2003-04-12      Michael Lauer   <mickey@Vanille.de>
         
         * Released as Version 1.0 (Beta)
         * GUI enhancements in the Menubar and the Toolbar.
         * Improved keyboard handling.
         * Added sanity checks for running Wellenreiter II as non-root or with dhcp clients in the background.
