What is the difference between the versions you provide?
The version 4.1 is a verry simple user interface with a lot smaller amount of features – but you can transcode audio. The tag support is also not so powerfull as in the later version. The version 4.1 is compatible with Windows XP, Vista, 7 and 8.
The version 8.9 is the last final build. with a lot more features then version 4.1. This version is compatible with Windows 7 and Windows 8 and not fully compatible with Windows XP and Vista.
The last beta is allways the current development release. You can use this version, if you are familier with beta versions – otherwise please use the version 8.9. The version 9 beta is compatible with Windows 8 and Windows 7 and not fully compatible with Windows XP and Vista.
