# Nixpkgs 26.11 (2026.11/??) {#sec-nixpkgs-release-26.11}

## Highlights {#sec-nixpkgs-release-26.11-highlights}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- The {file}`nixexprs.tar.xz` tarball will be discontinued together with Nixpkgs
  27.05 after 2027-12-31. Migrate to the {file}`nixexprs.tar.zst` tarball
  instead.

  This affects for example users who pull Nixpkgs as a flake input from
  https://channels.nixos.org:

  ```diff
  -nixpkgs.url = "https://channels.nixos.org/nixos-26.05/nixexprs.tar.xz";
  +nixpkgs.url = "https://channels.nixos.org/nixos-26.05/nixexprs.tar.zst";
  ```
