Now, as I have already mentioned (
LINK), I use the best OS in the world - NixOS.
NixOS has now - like every year - been updated to version 21.05 (Okapi)
What's new
There were updates in the following areas:
Core:
- gcc 9.3.0 -> 10.3.0

- kdaApplications 20.08.1 -> 20.12.3
- cinnamon 4.6 -> 4.8.1
Programming languages and frameworks:
- "Python optimizations" have been deactivated because builds are not reproducible. But they can be activated manually.

UPGRADE
Very important - make a backup before performing the upgrade!
To upgrade NixOS, proceed as follows.
First, you should check which channel you are using:
CHANNEL
nix-channel --list | grep nixos
Then the new 21.05 channel is added:
ADD CHANNEL
nix-channel --add https://nixos.org/channels/nixos-21.05 nixos
And last but not least, the actual upgrade via:
UPGRADE
nixos-rebuild switch --upgrade
Tada! - NixOS 21.05 - the best OS in the world!
