Backward Incompatibilities
When upgrading from a previous release, please be aware of the following
incompatible changes:
The minimum version of Nix required to evaluate Nixpkgs is now 2.0.
For users of NixOS 18.03 and 19.03, NixOS defaults to Nix 2.0, but
supports using Nix 1.11 by setting nix.package =
pkgs.nix1;. If this option is set to a Nix 1.11 package, you
will need to either unset the option or upgrade it to Nix 2.0.
For users of NixOS 17.09, you will first need to upgrade Nix by setting
nix.package = pkgs.nixStable2; and run
nixos-rebuild switch as the root
user.
For users of a daemon-less Nix installation on Linux or macOS, you can
upgrade Nix by running curl https://nixos.org/nix/install |
sh, or prior to doing a channel update, running
nix-env -iA nix.
If you have already run a channel update and Nix is no longer able to
evaluate Nixpkgs, the error message printed should provide adequate
directions for upgrading Nix.
For users of the Nix daemon on macOS, you can upgrade Nix by running
sudo -i sh -c 'nix-channel --update && nix-env -iA
nixpkgs.nix'; sudo launchctl stop org.nixos.nix-daemon; sudo launchctl
start org.nixos.nix-daemon.
Package rabbitmq_server is renamed to
rabbitmq-server.
The light module no longer uses setuid binaries, but
udev rules. As a consequence users of that module have to belong to the
video group in order to use the executable (i.e.
users.users.yourusername.extraGroups = ["video"];).
Buildbot now supports Python 3 and its packages have been moved to
pythonPackages. The options
and
can be used to select
the Python 2 or 3 version of the package.
Options
services.znc.confOptions.networks.name.userName and
services.znc.confOptions.networks.name.modulePackages
were removed. They were never used for anything and can therefore safely be removed.
Package wasm has been renamed proglodyte-wasm. The package
wasm will be pointed to ocamlPackages.wasm in 19.09, so
make sure to update your configuration if you want to keep proglodyte-wasmOther Notable Changes
The module gained the option
which determines the used
Matomo version.
