+	* Improved the speed reading the manufacturer list

 2003-12-18	Michael Lauer		<mickey@Vanille.de>
 
 	* Released as Version 1.0.2 (Development Snapshot)
-	* Add automatic uploading of capture files to "The Capture Dump" site at
+	* 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
-	* Remove deprecated setMonitorMode() API ==> Use setMode( "monitor" ) now.
+	* 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.
