Winamp 2.73 has been released by the guys of Nullsoft. Winamp is probably the most used MP3 player. Here are the changes:
* smaller main winamp.EXE
* new AVS version with larger interface
* seeking for HTTP/1.1 streamed MP3 files
* improved minibrowser functionality
* updated versions of MOD and MIDI plug-ins (thanks Jake and PP)
* made out_wm smaller (32k->7k)
* updated to newer, more efficient installer (1.1i)
As this has not been officialy released, you can find the posting that it's out here and download the file here...
