# Release X.Y (202?-??-??)

* `nix repl` has a new build-'n-link (`:bl`) command that builds a derivation
  while creating GC root symlinks.

* `nix build` has a new `--print-out-paths` flag to print the resulting output paths.
  This matches the default behaviour of `nix-build`.

nix repl: make symlinks with the :bl command Requested by ppepino on the Matrix: https://matrix.to/#/!KqkRjyTEzAGRiZFBYT:nixos.org/$Tb32BS3rVE2BSULAX4sPm0h6CDewX2hClOTGzTC7gwM?via=nixos.org&via=matrix.org&via=nixos.dev This adds a new command, :bl, which works like :b but also creates a GC root symlink to the various derivation outputs. ckie@cookiemonster ~/git/nix -> ./outputs/out/bin/nix repl Welcome to Nix 2.6.0.
