# Release 1.11 (2016-01-19)
|
||
|
||
This is primarily a bug fix release. It also has a number of new
|
||
features:
|
||
|
||
- `nix-prefetch-url` can now download URLs specified in a Nix
|
||
expression. For example,
|
||
|
||
$ nix-prefetch-url -A hello.src
|
||
|
||
will prefetch the file specified by the `fetchurl` call in the
|
||
attribute `hello.src` from the Nix expression in the current
|
||
directory, and print the cryptographic hash of the resulting file on
|
||
stdout. This differs from `nix-build -A
|
||
hello.src` in that it doesn't verify the hash, and is thus useful
|
||
when you’re updating a Nix expression.
|
||
|
||
You can also prefetch the result of functions that unpack a tarball,
|
||
such as `fetchFromGitHub`. For example:
|
||
|
||
$ nix-prefetch-url --unpack https://github.com/NixOS/patchelf/archive/0.8.tar.gz
|
||
|
||
or from a Nix expression:
|
||
|
||
$ nix-prefetch-url -A nix-repl.src
|
||
|
||
- The builtin function `<nix/fetchurl.nix>` now supports downloading
|
||
and unpacking NARs. This removes the need to have multiple downloads
|
||
in the Nixpkgs stdenv bootstrap process (like a separate busybox
|
||
binary for Linux, or curl/mkdir/sh/bzip2 for Darwin). Now all those
|
||
files can be combined into a single NAR, optionally compressed using
|
||
`xz`.
|
||
|
||
- Nix now supports SHA-512 hashes for verifying fixed-output
|
||
derivations, and in `builtins.hashString`.
|
||
|
||
- The new flag `--option build-repeat
|
||
N` will cause every build to be executed *N*+1 times. If the build
|
||
output differs between any round, the build is rejected, and the
|
||
output paths are not registered as valid. This is primarily useful
|
||
to verify build determinism. (We already had a `--check` option to
|
||
repeat a previously succeeded build. However, with `--check`,
|
||
non-deterministic builds are registered in the DB. Preventing that
|
||
is useful for Hydra to ensure that non-deterministic builds don't
|
||
end up getting published to the binary cache.)
|
||
|
||
- The options `--check` and `--option
|
||
build-repeat N`, if they detect a difference between two runs of the
|
||
same derivation and `-K` is given, will make the output of the other
|
||
run available under `store-path-check`. This makes it easier to
|
||
investigate the non-determinism using tools like `diffoscope`, e.g.,
|
||
|
||
$ nix-build pkgs/stdenv/linux -A stage1.pkgs.zlib --check -K
|
||
error: derivation ‘/nix/store/l54i8wlw2265…-zlib-1.2.8.drv’ may not
|
||
be deterministic: output ‘/nix/store/11a27shh6n2i…-zlib-1.2.8’
|
||
differs from ‘/nix/store/11a27shh6n2i…-zlib-1.2.8-check’
|
||
|
||
$ diffoscope /nix/store/11a27shh6n2i…-zlib-1.2.8 /nix/store/11a27shh6n2i…-zlib-1.2.8-check

|
||
- Improved FreeBSD support.
|
||
|
||
- `nix-env -qa --xml --meta` now prints license information.
|
||
|
||
- The maximum number of parallel TCP connections that the binary cache
|
||
substituter will use has been decreased from 150 to 25. This should
|
||
prevent upsetting some broken NAT routers, and also improves
|
||
performance.
|
||
|
||
- All "chroot"-containing strings got renamed to "sandbox". In
|
||
particular, some Nix options got renamed, but the old names are
|
||
still accepted as lower-priority aliases.
