Release 19.09

The 19.09 release branch became the stable branch in October, 2019.

Highlights

This release has the following notable changes:

• The programs.firefox.enableGoogleTalk and programs.firefox.enableIcedTea options are now deprecated and will only work if Firefox ESR 52.x is used.

• The home-manager tool now provides an uninstall sub-command that can be used to uninstall Home Manager, if used in the standalone mode. That is, not as a NixOS module.

State Version Changes

The state version in this release includes the changes below. These changes are only active if the home.stateVersion option is set to "19.09" or later.

• The programs.firefox.package option now expects a wrapped Firefox package and defaults to pkgs.firefox.

• The options home.keyboard.layout and home.keyboard.variant now default to null, which indicates that the system value should be used.
