I have the unpleasant duty of informing everyone that all plans to release
nixos-16.03 are OFF.

We were literally minutes away from tagging the source code and switching on
the nixos-16.03 channel when Domen realized that we had flat-out forgotten
to implement several important BLOCKERS that prevent us from releasing the
new version right now. So we had an on-line meeting, discussed our options,
and concluded to POSTPONE any new NixOS releases until the following issues
are resolved:

 - Re-designed UI for Nix command-line tools
 - Deterministic Reproducible Builds (#2281)
 - Security Hardening (#7220)
 - Fast Delivery of Security Updates (#10851)
 - Recursive Nix
 - Declarative User Environments a.k.a. User-space NixOS (#9250)
 - Hydra NG (#12203)
 - Lazier mkDerivation function (#11094)
 - Consistent Support for Multiple Outputs (#7701)

Once ALL these issues are implemented and tested, we'll start over with a
new release cycle.

Thank you for your patience and understanding,
Peter
