Earlier, the link to the changelog at https://kde.org/announcements/plasma/6/6.0.1/ did not work, but the one I used did. In the meantime, the link at https://kde.org/announcements/plasma/6/6.0.1/ works and the one I used does not. I assume that someone from KDE has adjusted the link in the meantime.
I have updated the link accordingly.
On Arch Linux, Plasma 6.0.1 was released a few minutes ago in the testing package sources.
~~I am curious if this version will reach the official repositories or if there are still reasons to delay an official release.~~
Edit: That went faster than expected. Plasma 6.0.1 has been moved from Testing to Extra.
