I have an unfortunate announcement to make. Due to a software upgrade the commenting system will lose all comments. This has to do something with the upgrade of the package dependency on persistent to a version greater than 2.0.
I will wait until my issues with other dependencies are closed for pushing some dependency boundaries, so it will build on the server without dependency hell.
EDIT from 30.12.2014:
After looking deeper into that matter, I have fund out, that I will be able to migrate the data. So no dataloss will happen. Sorry for the hassle.
