Release 26.11

This is the current unstable branch and the information in this section is therefore not final.

Highlights

This release has the following notable changes:

• The programs.uv.enable module can now install uv-managed Python versions and tools through the new programs.uv.python.versions, programs.uv.python.default, and programs.uv.tool.packages options. Unpinned entries track the latest release on each activation while pinned ones stay put, and programs.uv.python.prune / programs.uv.tool.prune make the managed set fully declarative by removing versions and tools that are no longer listed.

• On Darwin, Home Manager launchd agents now support launchd.agents.name.domain to choose either the user’s GUI or background launchd domain. Background services provided by Home Manager now use the user domain, which allows activations from contexts such as SSH sessions without requiring an active graphical login session.

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 “26.11” or later.

• The KDL options under programs.zellij will now correctly escape backslashes in string values. For example, the Nix string "\\" will now correctly generate the KDL string "\\". Previously, this would have generated "\", which is invalid KDL. The following options are affected:
  • programs.zellij.settings
  • programs.zellij.themes
  • programs.zellij.layouts
