[[sec-release-21.05-highlights]]
=== Highlights

This release has the following notable changes:

* The <<opt-programs.broot.verbs>> option is now a list rather than an
attribute set. To migrate, move the keys of the attrset into the list
items' `invocation` keys. For example,
+
[source,nix]
----
programs.broot.verbs = {
  "p" = { execution = ":parent"; };
};
----
+
becomes
+
[source,nix]
----
programs.broot.verbs = [
  {
    invocation = "p";
    execution = ":parent";
  }
];
----

* The <<opt-programs.mpv.package>> option has been changed to allow custom
derivations. The following configuration is now possible:
+
[source,nix]
----
programs.mpv.package = (pkgs.wrapMpv (pkgs.mpv-unwrapped.override {
  vapoursynthSupport = true;
}) {
  extraMakeWrapperArgs = [
    "--prefix" "LD_LIBRARY_PATH" ":" "${pkgs.vapoursynth-mvtools}/lib/vapoursynth"
  ];
});
----
+
As a result of this change, <<opt-programs.mpv.package>> is no longer the
resulting derivation. Use the newly introduced `programs.mpv.finalPackage`
instead.

* The <<opt-programs.rofi.extraConfig>> option is now an attribute set rather
than a string. To migrate, move each line into the attribute set,
removing the `rofi.` prefix from the keys. For example,
+
[source,nix]
----
programs.rofi.extraConfig = ''
  rofi.show-icons: true
  rofi.modi: drun,emoji,ssh
'';
----
+
becomes
+
[source,nix]
----
programs.rofi.extraConfig = {
  show-icons = true;
  modi = "drun,emoji,ssh";
};
----
+
* The <<opt-programs.rofi.theme>> option now supports defining a theme
using an attribute set, the following configuration is now possible:
+
[source,nix]
----
programs.rofi.theme = let
  # Necessary to avoid quoting non-string values
  inherit (config.lib.formats.rasi) mkLiteral;
in {
   "@import" = "~/.config/rofi/theme.rasi";

  "*" = {
    background-color = mkLiteral "#000000";
    foreground-color = mkLiteral "rgba ( 250, 251, 252, 100 % )";
    border-color = mkLiteral "#FFFFFF";
    width = 512;
  };

  "#textbox-prompt-colon" = {
    expand = false;
    str = ":";
    margin = mkLiteral "0px 0.3em 0em 0em";
    text-color = mkLiteral "@foreground-color";
  };
};
----


* The `services.redshift.extraOptions` and `services.gammastep.extraOptions`
options were removed in favor of <<opt-services.redshift.settings>> and
`services.gammastep.settings`, that are now an attribute set rather
than a string. They also support new features not available before, for
example:
+
[source,nix]
----
services.redshift = {
  dawnTime = "6:00-7:45";
  duskTime = "18:35-20:15";
  settings = {
    redshift = {
      gamma = 0.8;
      adjustment-method = "randr";
    };

    randr = {
      screen = 0;
    };
  };
};
----
+
It is recommended to check either
https://github.com/jonls/redshift/blob/master/redshift.conf.sample[redshift.conf.sample] or
https://gitlab.com/chinstrap/gammastep/-/blob/master/gammastep.conf.sample[gammastep.conf.sample]
for the available additional options in each program.

* Specifying `programs.neomutt.binds.map` or `programs.neomutt.macros.map` as a
  single string is now deprecated in favor of specfiying it as a list of
  strings.

* The `programs.neovim.configure` is deprecated in favor of other `programs.neovim` options;
please use the other options at your disposal:
+
[source,nix]
----
configure.packages.*.opt  -> programs.neovim.plugins = [ { plugin = ...; optional = true; }]
configure.packages.*.start  -> programs.neovim.plugins = [ { plugin = ...; }]
configure.customRC -> programs.neovim.extraConfig
----

* Home Manager now respects the `NO_COLOR` environment variable as per
https://no-color.org/[].

* Qt module now supports <<opt-qt.style.name>> to specify a theme name and
<<opt-qt.style.package>> to specify a theme package. If you have set
<<opt-qt.platformTheme>> to `gnome`, a <<opt-qt.style.package>> compatible
with both Qt and Gtk is now required to be set. For instance:
+
[source,nix]
----
qt = {
  platformTheme = "gnome";
  style = {
    name = "adwaita-dark";
    package = pkgs.adwaita-qt;
  };
};
----

* The library type `fontType` now has a `size` attribute in addition to `name`. For example:
+
[source,nix]
----
font = {
  name = "DejaVu Sans";
  size = 8;
};
----

* The <<opt-programs.htop.settings>> option is introduced to replace individual
options in `programs.htop`. To migrate, set the htop options directly in
<<opt-programs.htop.settings>>. For example:
+
[source,nix]
----
programs.htop = {
  enabled = true;
  settings = {
     color_scheme = 5;
     delay = 15;
     highlight_base_name = 1;
     highlight_megabytes = 1;
     highlight_threads = 1;
  };
};
----

=== State Version Changes

The state version in this release includes the changes below. These

  `$XDG_CONFIG_HOME/newsboat`.
