Plugin Name: Audio player
Plugin URI: http://www.1pixelout.net/code/audio-player-wordpress-plugin/

Version: 1.0
Author: Martin Laine
Author URI: http://www.1pixelout.net

Change log:

	1.0 (26 December 2005)
		
		* Player now based on the emff player (http://www.marcreichelt.de/)
		* New thinner design (suggested by Don Bledsoe - http://screenwriterradio.com/)
		* More colour options
		* New slider function to move around the track
		* Simple scrolling ID3 tag support for title and artist (thanks to Ari - http://www.adrstudios.com/)
		* Time display now includes hours for very long tracks
		* Support for autostart and loop (suggested by gotjosh - http://gotblogua.gotjosh.net/)
		* Support for custom colours per player instance
		* Fixed an issue with rss feeds. Post content in rss feeds now only shows a link to the file rather than the player (thanks to Blair Kitchen - http://96rpm.the-blair.com/)
		* Better handling of buffering and file not found errors 

	0.7.1 beta (29 October 2005)

		* MP3 files are no longer pre-loaded (saves on bandwidth if you have multiple players on one page)

	0.7 beta (24 October 2005)

		* Added colour customisation.

	0.6 beta (23 October 2005)

		* Fixed bug in flash player: progress bar was not updating properly.

	0.5 beta (19 October 2005)

		* Moved player.swf to plugins folder
		* Default location of audio files is now top-level /audio folder
		* Better handling of paths and URIs
		* Added support for linking to external files

	0.2 beta (19 October 2005)

		* Bug fix: the paths to the flash player and the mp3 files didn?t respect the web path option. This caused problems for blogs that don?t live in the root of the domain (eg www.mydomain.com/blog/)
