When upgrading components using pre-built binaries + (through nix-pull / nix-channel), Nix can automatically download and + apply binary patches to already installed components instead of full + downloads. Patching is “smart”: if there is a *sequence* of patches + to an installed component, Nix will use it. Patches are currently + generated automatically between Nixpkgs (pre-)releases. + + - Simplifications to the substitute mechanism. + + - Nix-pull now stores downloaded manifests in + `/nix/var/nix/manifests`. + + - Metadata on files in the Nix store is canonicalised after builds: + the last-modified timestamp is set to 0 (00:00:00 1/1/1970), the + mode is set to 0444 or 0555 (readable and possibly executable by + all; setuid/setgid bits are dropped), and the group is set to the + default. This ensures that the result of a build and an installation + through a substitute is the same; and that timestamp dependencies + are revealed. |
