The option's description was incorrect regarding ownership management and has been simplified greatly.

+
+ The security.apparmor module,
+ for the AppArmor
+ Mandatory Access Control system,
+ has been substantialy improved along with related tools,
+ so that module maintainers can now more easily write AppArmor profiles for NixOS.
+ The most notable change on the user-side is the new option ,
+ replacing the previous profiles option
+ to provide a way to disable a profile
+ and to select whether to confine in enforce mode (default)
+ or in complain mode (see journalctl -b --grep apparmor).
+ Security-minded users may also want to enable ,
+ at the cost of having some of their processes killed
+ when updating to a NixOS version introducing new AppArmor profiles.

The GNOME desktop manager once again installs gnome3.epiphany by default.
