A highlight of the release is Nix 2.8, which brings experimental flakes support for the default installed Nix version, along with tonnes of fixes, features and general improvements, like @pennae's work to improve performance. The other notable change is the new graphical installer, which @vlinkz led the integration of with @davidak doing a lot of additional work. This feature, enabled by default in the graphical ISOs, will hopefully make initial setup easier for new users and existing users setting up new NixOS machines. Of course, these are just two things I want to highlight here. Not to mention the countless improvements, bug fixes and new features that have also gone into this release. I would like to thank every single contributor who has contributed to this release.
