Yep, no major changes within a single x.y series.  Of course, read the release notes (they're on the website), they will tell you anything special you need to be aware of.

We don't directly provide any distro packages, but the maintainers of the cyrus packages for Debian and Fedora are doing a great job.  We don't hear directly from other distros much, but I guess that's because most other distros leverage Debian and/or Fedora's work?

Most of us cyrus developers are running Debian on our own systems, and FastMail's servers run Debian, so even without an official package, a source build on Debian will generally just work (but then you have to choose/configure features/dependencies yourself, of course...).
