I think the link to the KSPP issue tracker should stay. If something,
just changing 'Github:' to 'Link:'

The KSPP has been an active _upstream_ project for about 7 years now,
and the issue tracker is publicly available. :) So it's not like a random
link to a random project. This also help us to automatically keep track
of the patches sent out to address a particular issue that we want to
have resolved upstream. So please, keep the link in the changelog text,
it's useful. :)

Thanks
