GOG Team, please provide list of bugfixes. Many people are interested in what you have changed. On main site there is mention that you fixed numerous bugs.

It looks to be purely related to Windows support as there are not real changes to the game code.

Post 1.0, there was an issue the official patches introduced that caused the music to stop playing on the character and multiplayer selection screens. This bug was still present in retail 1.09. At long last, it looks like they addressed it in the GOG release.
