[Nix-dev] Nix 1.5.3 released

[Eelco Dolstra]

Hi,

I'm pleased to announce the availability of a new stable release of the
Nix package manager.  Release 1.5.3 can be found at

  http://hydra.nixos.org/release/nix/nix-1.5.3

This is primarily a bug fix release. The following changes are noteworthy:

  * Yet another security bug involving hard links to files outside the store
    was fixed. This bug only affected multi-user installations that do not have
    hard link restrictions enabled. (NixOS is thus not vulnerable.)

  * The default binary cache URL has changed from http://nixos.org/binary-cache
    to http://cache.nixos.org. The latter is hosted on Amazon CloudFront
    (courtesy of LogicBlox) and should provide better performance for users in
    both Europe and North America.

  * The binary cache substituter now prints a warning message if fetching
    information from the cache takes more than five seconds. Thus network or
    server problems no longer make Nix appear to just hang.

  * Stack traces now show function names, e.g.

    while evaluating `concatMapStrings' at `.../nixpkgs/pkgs/lib/strings.nix:18:25':

    Also, if a function is called with an unexpected argument, Nix now shows
    the name of the argument.
