I have just updated my Nextcloud install from Nextcloud 16 to Nextcloud 17. It’s a Docker-based installation on my Odroid HC2, which I use for a lot of self-hosted softwares. (Thanks to Docker I can forget about all things PHP!) The update worked without problems. And my first subjective impression is, that it runs a bit faster than before. I really appreciate that Nextcloud improves the code with every release, so that it runs faster before, although often new features get added.
