[[sec-release-19.03]]
== Release 19.03
The 19.03 release branch became the stable branch in April, 2019.
[[sec-release-19.03-highlights]]
=== Highlights
:opt-home-file-source: opt-home.file._name__.source
This release has the following notable changes:
* The <<{opt-home-file-source}>> option now allows source files to be
hidden, that is, having a name starting with the `.` character. It
also allows the source file name to contain characters not typically
allowed for Nix store paths. For example, your configuration can now
contain things such as
+
[source,nix]
----
home.file."my file".source = ./. + "/file with spaces!";
----
* The type used for the systemd unit options under
<<opt-systemd.user.services>>, <<opt-systemd.user.sockets>>, etc. has
been changed to offer more robust merging of configurations. If you
don't override values within systemd units then you are not affected
by this change. Unfortunately, if you do override unit values you may
encounter errors.
+
In particular, if you get an error saying that a ``unique option'' is
``defined multiple times'' then you need to use the
https://nixos.org/nixos/manual/#sec-option-definitions-setting-priorities[`mkForce`]
function. For example,
+
[source,nix]
----
systemd.user.services.foo.Service.ExecStart = "/foo/bar";
----
+
becomes
+
[source,nix]
----
systemd.user.services.foo.Service.ExecStart = lib.mkForce "/foo/bar";
----
+
We had to make this change because the old merging was causing too
many confusing situations for people.
[[sec-release-19.03-state-version-changes]]
=== State Version Changes
The state version in this release includes the changes below. These
changes are only active if the <<opt-home.stateVersion>> option is set
to ``19.03'' or later.
* There is now an option <<opt-programs.beets.enable>> that defaults
to `false`. Before the module would be active if the
<<opt-programs.beets.settings>> option was non-empty.
