The 19.03 release branch became the stable branch in April, 2019.

This release has the following notable changes: The home.file.<name?>.source 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 home.file."my file".source = ./. + "/file with spaces!";

The state version in this release includes the changes below. These changes are only active if the home.stateVersion option is set to "19.03" or later. There is now an option programs.beets.enable that defaults to false. Before the module would be active if the programs.beets.settings option was non-empty.
