What is a point release?
A point release does not designate a separate, new version of Qubes OS. Rather, it designates its respective major or minor release (in this case, 4.0) inclusive of all updates up to a certain point. Installing Qubes 4.0 and fully updating it results in the same system as installing Qubes 4.0.4.
What should I do?
If you installed Qubes 4.0, 4.0.1, 4.0.2, or 4.0.3 and have fully updated, then your system is already equivalent to a Qubes 4.0.4 installation. No further action is required.
Regardless of your current OS, if you wish to install (or reinstall) Qubes 4.0 for any reason, then the 4.0.4 ISO makes this more convenient and secure, since it bundles all Qubes 4.0 updates to date. Please see the installation guide for detailed instructions.
If you’re willing to test this release candidate, you can help to improve the stable release by reporting any bugs you encounter.
