 # Nix Release Notes
 
+The Nix release cycle is calendar-based as follows:
+
 Nix has a release cycle of roughly 6 weeks.
 Notable changes and additions are announced in the release notes for each version.
 
-Bugfixes can be backported on request to previous Nix releases.
-We typically backport only as far back as the Nix version used in the latest NixOS release, which is announced in the [NixOS release notes](https://nixos.org/manual/nixos/stable/release-notes.html#ch-release-notes).
-
-Backports never skip releases.
-If a feature is backported to version `x.y`, it must also be available in version `x.(y+1)`.
-This ensures that upgrading from an older version with backports is still safe and no backported functionality will go missing.
+The supported Nix versions are:
+- The latest release
+- The version used in the stable NixOS release, which is announced in the [NixOS release notes](https://nixos.org/manual/nixos/stable/release-notes.html#ch-release-notes).
 
+Bugfixes and security issues are backported to every supported version.
+Patch releases are published as needed.
