the horde groupware app seems to be pretty outdated. Version 5.2.7 is quite old, it was released mid 2015. Since then there where several releases that fixed different security problems - not to mention the many normal bug fixes and new features.
Are there any plans to update it or is it possible to update it on my own trough pear?
thanks for the information. Over the weekend I had some spare time and installed a horde on my own. It was quite easy - thanks to Univention I could copy the configuration from the app.
