I know that most of you miss Mashup. A method to get it back working and prevent the auto-update has been posted on The Ugly Duckling website.
Here is the summary from the website:
- Download this zip file: http://is.gd/mashuplatest
- Open your XBMC (Kodi) and go to System>Settings>Addons>Install from zip file and navigate to the downloaded zip file. Wait a little bit until you see that Mashup is enabled.
