Sorry my friend! Just found it in the files:
changelog.txt
readme.txt
I recommend to put this Information directly in the WordPress (backend), so updates can be done faster?!

Hi Pascal,
Currently this is only possible with plugins, via Plugins > Editor. There you can select / view txt files. So readme and changelog file. Unfortunately you cannot select / view txt files with themes (Appearance > Editor). And there’s also no changelog listed on the theme page on wp dot org. But as far as I know they are working on a new theme directory.. So I hope changelog will be listed then.
Are you having troubles with certain parts of my recent updates?
Guido
Hey Guido,
thanks for your answer. No! At the moment all´s fine. Thanks
