Primary breaking change + is for the common usage of `nix repl '<nixpkgs>'` which can be recovered with + `nix repl --file '<nixpkgs>'` or `nix repl --expr 'import <nixpkgs>{}'`. + + This is currently guarded by the `repl-flake` experimental feature. + +* A new function `builtins.traceVerbose` is available.
