+
+<title>Release 0.11 (December 31, 2007)</title>
+
+<para>Nix 0.11 has many improvements over the previous stable release.
+The most important improvement is secure multi-user support.  It also
+features many usability enhancements and language extensions, many of
+them prompted by NixOS, the purely functional Linux distribution based
+on Nix.  Here is an (incomplete) list:</para>
+
+
+<itemizedlist>
+
+
+  <listitem><para>Secure multi-user support.  A single Nix store can
+  now be shared between multiple (possible untrusted) users.  This is
+  an important feature for NixOS, where it allows non-root users to
+  install software.  The old setuid method for sharing a store between
+  multiple users has been removed.  Details for setting up a
+  multi-user store can be found in the manual.</para></listitem>
+
+
+  <listitem><para>The new command <command>nix-copy-closure</command>
+  gives you an easy and efficient way to exchange software between
+  machines.  It copies the missing parts of the closure of a set of
+  store path to or from a remote machine via
+  <command>ssh</command>.</para></listitem>
+
+
+  <listitem><para>A new kind of string literal: strings between double
+  single-quotes (<literal>''</literal>) have indentation
+  “intelligently” removed.  This allows large strings (such as shell
+  scripts or configuration file fragments in NixOS) to cleanly follow
+  the indentation of the surrounding expression.  It also requires
+  much less escaping, since <literal>''</literal> is less common in
+  most languages than <literal>"</literal>.</para></listitem>
+
+
+  <listitem><para><command>nix-env</command> <option>--set</option>
+  modifies the current generation of a profile so that it contains
+  exactly the specified derivation, and nothing else.  For example,
+  <literal>nix-env -p /nix/var/nix/profiles/browser --set
+  firefox</literal> lets the profile named
+  <filename>browser</filename> contain just Firefox.</para></listitem>
+
+
+  <listitem><para><command>nix-env</command> now maintains
+  meta-information about installed packages in profiles.  The
+  meta-information is the contents of the <varname>meta</varname>
+  attribute of derivations, such as <varname>description</varname> or
+  <varname>homepage</varname>.  The command <literal>nix-env -q --xml
+  --meta</literal> shows all meta-information.</para></listitem>
+
+
+  <listitem><para><command>nix-env</command> now uses the
+  <varname>meta.priority</varname> attribute of derivations to resolve
+  filename collisions between packages.  Lower priority values denote
+  a higher priority.  For instance, the GCC wrapper package and the
+  Binutils package in Nixpkgs both have a file
+  <filename>bin/ld</filename>, so previously if you tried to install
+  both you would get a collision.  Now, on the other hand, the GCC
+  wrapper declares a higher priority than Binutils, so the former’s
+  <filename>bin/ld</filename> is symlinked in the user
+  environment.</para></listitem>

+
+<title>Release 0.12 (November 20, 2008)</title>
+
+<itemizedlist>
+
+  <listitem>
+    <para>Nix no longer uses Berkeley DB to store Nix store metadata.
+    The principal advantages of the new storage scheme are: it works
+    properly over decent implementations of NFS (allowing Nix stores
+    to be shared between multiple machines); no recovery is needed
+    when a Nix process crashes; no write access is needed for
+    read-only operations; no more running out of Berkeley DB locks on
+    certain operations.</para>
+
+    <para>You still need to compile Nix with Berkeley DB support if
+    you want Nix to automatically convert your old Nix store to the
+    new schema.  If you don’t need this, you can build Nix with the
+    <filename>configure</filename> option
+    <option>--disable-old-db-compat</option>.</para>
+
+    <para>After the automatic conversion to the new schema, you can
+    delete the old Berkeley DB files:
+
+    <screen>
+$ cd /nix/var/nix/db
+$ rm __db* log.* derivers references referrers reserved validpaths DB_CONFIG</screen>
+
+    The new metadata is stored in the directories
+    <filename>/nix/var/nix/db/info</filename> and
+    <filename>/nix/var/nix/db/referrer</filename>.  Though the
+    metadata is stored in human-readable plain-text files, they are
+    not intended to be human-editable, as Nix is rather strict about
+    the format.</para>
+
+    <para>The new storage schema may or may not require less disk
+    space than the Berkeley DB environment, mostly depending on the
+    cluster size of your file system.  With 1 KiB clusters (which
+    seems to be the <literal>ext3</literal> default nowadays) it
+    usually takes up much less space.</para>
+  </listitem>
+
+  <listitem><para>There is a new substituter that copies paths
+  directly from other (remote) Nix stores mounted somewhere in the
+  filesystem.  For instance, you can speed up an installation by
+  mounting some remote Nix store that already has the packages in
+  question via NFS or <literal>sshfs</literal>.  The environment
+  variable <envar>NIX_OTHER_STORES</envar> specifies the locations of
+  the remote Nix directories,
+  e.g. <literal>/mnt/remote-fs/nix</literal>.</para></listitem>
+
+  <listitem><para>New <command>nix-store</command> operations
+  <option>--dump-db</option> and <option>--load-db</option> to dump
+  and reload the Nix database.</para></listitem>
+
+  <listitem><para>The garbage collector has a number of new options to
+  allow only some of the garbage to be deleted.  The option
+  <option>--max-freed <replaceable>N</replaceable></option> tells the
+  collector to stop after at least <replaceable>N</replaceable> bytes
+  have been deleted.  The option <option>--max-links
+  <replaceable>N</replaceable></option> tells it to stop after the
+  link count on <filename>/nix/store</filename> has dropped below
+  <replaceable>N</replaceable>.  This is useful for very large Nix
+  stores on filesystems with a 32000 subdirectories limit (like
+  <literal>ext3</literal>).  The option <option>--use-atime</option>
+  causes store paths to be deleted in order of ascending last access
+  time.  This allows non-recently used stuff to be deleted.  The
+  option <option>--max-atime <replaceable>time</replaceable></option>
+  specifies an upper limit to the last accessed time of paths that may
+  be deleted.  For instance,
+
+    <screen>
+    $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")</screen>
+
+  deletes everything that hasn’t been accessed in two months.</para></listitem>
+
+  <listitem><para><command>nix-env</command> now uses optimistic
+  profile locking when performing an operation like installing or
+  upgrading, instead of setting an exclusive lock on the profile.
+  This allows multiple <command>nix-env -i / -u / -e</command>
+  operations on the same profile in parallel.  If a
+  <command>nix-env</command> operation sees at the end that the profile
+  was changed in the meantime by another process, it will just
+  restart.  This is generally cheap because the build results are
+  still in the Nix store.</para></listitem>
+
+  <listitem><para>The option <option>--dry-run</option> is now
+  supported by <command>nix-store -r</command> and

+  and which paths will be substituted) is now always shown by
+  <command>nix-env</command>, <command>nix-store -r</command> and
+  <command>nix-build</command>.  The total download size of
+  substitutable paths is now also shown.  For instance, a build will

+    <para>The Nix expression evaluator is now much faster in most

+      Support for configurable parallelism inside builders.  Build
+      scripts have always had the ability to perform multiple build
+      actions in parallel (for instance, by running <command>make -j
+      2</command>), but this was not desirable because the number of
+      actions to be performed in parallel was not configurable.  Nix
+      now has an option <option>--cores
+      <replaceable>N</replaceable></option> as well as a configuration
+      setting <varname>build-cores =
+      <replaceable>N</replaceable></varname> that causes the
+      environment variable <envar>NIX_BUILD_CORES</envar> to be set to
+      <replaceable>N</replaceable> when the builder is invoked.  The
+      builder can use this at its discretion to perform a parallel
+      build, e.g., by calling <command>make -j
+      <replaceable>N</replaceable></command>.  In Nixpkgs, this can be
+      enabled on a per-package basis by setting the derivation
+      attribute <varname>enableParallelBuilding</varname> to
+      <literal>true</literal>.

+<title>Release 0.8 (April 11, 2005)</title>
+
+<para>NOTE: the hashing scheme in Nix 0.8 changed (as detailed below).
+As a result, <command>nix-pull</command> manifests and channels built
+for Nix 0.7 and below will now work anymore.  However, the Nix
+expression language has not changed, so you can still build from
+source.  Also, existing user environments continue to work.  Nix 0.8
+will automatically upgrade the database schema of previous
+installations when it is first run.</para>
+
+<para>If you get the error message
+
+<screen>
+you have an old-style manifest `/nix/var/nix/manifests/[...]'; please

+
+you should delete previously downloaded manifests:

+$ rm /nix/var/nix/manifests/*</screen>
+
+If <command>nix-channel</command> gives the error message
+
+<screen>
+manifest `http://catamaran.labs.cs.uu.nl/dist/nix/channels/[channel]/MANIFEST'
+is too old (i.e., for Nix &lt;= 0.7)</screen>
+
+then you should unsubscribe from the offending channel
+(<command>nix-channel --remove
+<replaceable>URL</replaceable></command>; leave out
+<literal>/MANIFEST</literal>), and subscribe to the same URL, with
+<literal>channels</literal> replaced by <literal>channels-v3</literal>
+(e.g., <link
+xlink:href='http://catamaran.labs.cs.uu.nl/dist/nix/channels-v3/nixpkgs-unstable'
+/>).</para>
+
+<para>Nix 0.8 has the following improvements:
+
+<itemizedlist>
+
+  <listitem><para>The cryptographic hashes used in store paths are now
+  160 bits long, but encoded in base-32 so that they are still only 32
+  characters long (e.g.,
+  <filename>/nix/store/csw87wag8bqlqk7ipllbwypb14xainap-atk-1.9.0</filename>).
+  (This is actually a 160 bit truncation of a SHA-256
+  hash.)</para></listitem>
+
+  <listitem><para>Big cleanups and simplifications of the basic store
+  semantics.  The notion of “closure store expressions” is gone (and
+  so is the notion of “successors”); the file system references of a
+  store path are now just stored in the database.</para>
+
+  <para>For instance, given any store path, you can query its closure:
+
+  <screen>
+$ nix-store -qR $(which firefox)
+... lots of paths ...</screen>
+
+  Also, Nix now remembers for each store path the derivation that
+  built it (the “deriver”):
+
+  <screen>
+$ nix-store -qR $(which firefox)
+/nix/store/4b0jx7vq80l9aqcnkszxhymsf1ffa5jd-firefox-1.0.1.drv</screen>
+
+  So to see the build-time dependencies, you can do
+
+  <screen>
+$ nix-store -qR $(nix-store -qd $(which firefox))</screen>
+
+  or, in a nicer format:
+
+  <screen>
+$ nix-store -q --tree $(nix-store -qd $(which firefox))</screen>
+
+  </para>
+
+  <para>File system references are also stored in reverse.  For
+  instance, you can query all paths that directly or indirectly use a
+  certain Glibc:
+
+  <screen>
+$ nix-store -q --referrers-closure \
+    /nix/store/8lz9yc6zgmc0vlqmn2ipcpkjlmbi51vv-glibc-2.3.4</screen>
+
+  </para>
+
+  </listitem>
+
+  <listitem><para>The concept of fixed-output derivations has been
+  formalised.  Previously, functions such as
+  <function>fetchurl</function> in Nixpkgs used a hack (namely,
+  explicitly specifying a store path hash) to prevent changes to, say,
+  the URL of the file from propagating upwards through the dependency
+  graph, causing rebuilds of everything.  This can now be done cleanly
+  by specifying the <varname>outputHash</varname> and
+  <varname>outputHashAlgo</varname> attributes.  Nix itself checks
+  that the content of the output has the specified hash.  (This is
+  important for maintaining certain invariants necessary for future
+  work on secure shared stores.)</para></listitem>
+
+  <listitem><para>One-click installation :-) It is now possible to
+  install any top-level component in Nixpkgs directly, through the web
+  — see, e.g., <link
+  xlink:href='http://catamaran.labs.cs.uu.nl/dist/nixpkgs-0.8/' />.
+  All you have to do is associate
+  <filename>/nix/bin/nix-install-package</filename> with the MIME type
+  <literal>application/nix-package</literal> (or the extension
+  <filename>.nixpkg</filename>), and clicking on a package link will
+  cause it to be installed, with all appropriate dependencies.  If you
+  just want to install some specific application, this is easier than
+  subscribing to a channel.</para></listitem>
+
+  <listitem><para><command>nix-store -r
+  <replaceable>PATHS</replaceable></command> now builds all the
+  derivations PATHS in parallel.  Previously it did them sequentially
+  (though exploiting possible parallelism between subderivations).
+  This is nice for build farms.</para></listitem>

+

+
+    <listitem><para>Install a store derivation directly (bypassing the
+    Nix expression language entirely):
+
+    <screen>
+$ nix-env -i /nix/store/z58v41v21xd3...-aterm-2.3.1.drv</screen>
+
+    (This is used to implement <command>nix-install-package</command>,
+    which is therefore immune to evolution in the Nix expression
+    language.)</para></listitem>
+
+    <listitem><para>Install an already built store path directly:

+
+    The difference with the normal installation mode is that
+    <option>-E</option> does not use the <varname>name</varname>

+<itemizedlist>
+
+  <listitem>
+    <para>Nix can now optionally use the Boehm garbage collector.
+    This significantly reduces the Nix evaluator’s memory footprint,
+    especially when evaluating large NixOS system configurations.  It
+    can be enabled using the <option>--enable-gc</option> configure
+    option.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now uses SQLite for its database.  This is faster and
+    more flexible than the old <emphasis>ad hoc</emphasis> format.
+    SQLite is also used to cache the manifests in
+    <filename>/nix/var/nix/manifests</filename>, resulting in a
+    significant speedup.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now has an search path for expressions.  The search path
+    is set using the environment variable <envar>NIX_PATH</envar> and
+    the <option>-I</option> command line option.  In Nix expressions,
+    paths between angle brackets are used to specify files that must
+    be looked up in the search path.  For instance, the expression
+    <literal>&lt;nixpkgs/default.nix></literal> looks for a file
+    <filename>nixpkgs/default.nix</filename> relative to every element
+    in the search path.</para>
+  </listitem>
+
+  <listitem>
+    <para>The new command <command>nix-build --run-env</command>
+    builds all dependencies of a derivation, then starts a shell in an

+
+  <listitem>
+    <para>Attribute names can now be arbitrary strings.  For instance,

+    bla"</literal>.</para>
+  </listitem>
+

+  </listitem>
+
+  <listitem>
+    <para>On Linux, Nix will now make files in the Nix store immutable
+    on filesystems that support it.  This prevents accidental
+    modification of files in the store by the root user.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix has preliminary support for derivations with multiple
+    outputs.  This is useful because it allows parts of a package to
+    be deployed and garbage-collected separately.  For instance,
+    development parts of a package such as header files or static
+    libraries would typically not be part of the closure of an
+    application, resulting in reduced disk usage and installation
+    time.</para>

+<title>Release 1.1 (July 18, 2012)</title>
+
+<para>This release has the following improvements:</para>
+
+<itemizedlist>
+
+  <listitem>
+    <para>On Linux, when doing a chroot build, Nix now uses various
+    namespace features provided by the Linux kernel to improve
+    build isolation.  Namely:
+    <itemizedlist>
+      <listitem><para>The private network namespace ensures that
+      builders cannot talk to the outside world (or vice versa): each
+      build only sees a private loopback interface.  This also means
+      that two concurrent builds can listen on the same port (e.g. as
+      part of a test) without conflicting with each
+      other.</para></listitem>
+      <listitem><para>The PID namespace causes each build to start as
+      PID 1.  Processes outside of the chroot are not visible to those
+      on the inside.  On the other hand, processes inside the chroot
+      <emphasis>are</emphasis> visible from the outside (though with
+      different PIDs).</para></listitem>
+      <listitem><para>The IPC namespace prevents the builder from
+      communicating with outside processes using SysV IPC mechanisms
+      (shared memory, message queues, semaphores).  It also ensures
+      that all IPC objects are destroyed when the builder
+      exits.</para></listitem>
+      <listitem><para>The UTS namespace ensures that builders see a
+      hostname of <literal>localhost</literal> rather than the actual
+      hostname.</para></listitem>
+      <listitem><para>The private mount namespace was already used by
+      Nix to ensure that the bind-mounts used to set up the chroot are
+      cleaned up automatically.</para></listitem>
+    </itemizedlist>
+    </para>
+  </listitem>
+
+  <listitem>
+    <para>Build logs are now compressed using
+    <command>bzip2</command>.  The command <command>nix-store
+    -l</command> decompresses them on the fly.  This can be disabled
+    by setting the option <literal>build-compress-log</literal> to
+    <literal>false</literal>.</para>
+  </listitem>
+
+  <listitem>
+    <para>The creation of build logs in
+    <filename>/nix/var/log/nix/drvs</filename> can be disabled by
+    setting the new option <literal>build-keep-log</literal> to
+    <literal>false</literal>.  This is useful, for instance, for Hydra
+    build machines.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now reserves some space in
+    <filename>/nix/var/nix/db/reserved</filename> to ensure that the
+    garbage collector can run successfully if the disk is full.  This
+    is necessary because SQLite transactions fail if the disk is
+    full.</para>
+  </listitem>
+
+  <listitem>
+    <para>Added a basic <function>fetchurl</function> function.  This
+    is not intended to replace the <function>fetchurl</function> in
+    Nixpkgs, but is useful for bootstrapping; e.g., it will allow us
+    to get rid of the bootstrap binaries in the Nixpkgs source tree
+    and download them instead.  You can use it by doing
+    <literal>import &lt;nix/fetchurl.nix> { url =
+    <replaceable>url</replaceable>; sha256 =
+    "<replaceable>hash</replaceable>"; }</literal>. (Shea Levy)</para>
+  </listitem>
+
+  <listitem>
+    <para>Improved RPM spec file. (Michel Alexandre Salim)</para>

+
+<title>Release 1.2 (December 6, 2012)</title>
+
+<para>This release has the following improvements and changes:</para>
+
+<itemizedlist>
+
+  <listitem>
+    <para>Nix has a new binary substituter mechanism: the
+    <emphasis>binary cache</emphasis>.  A binary cache contains
+    pre-built binaries of Nix packages.  Whenever Nix wants to build a
+    missing Nix store path, it will check a set of binary caches to
+    see if any of them has a pre-built binary of that path.  The
+    configuration setting <option>binary-caches</option> contains a
+    list of URLs of binary caches.  For instance, doing
+<screen>
+$ nix-env -i thunderbird --option binary-caches http://cache.nixos.org
+</screen>
+    will install Thunderbird and its dependencies, using the available
+    pre-built binaries in <uri>http://cache.nixos.org</uri>.
+    The main advantage over the old “manifest”-based method of getting
+    pre-built binaries is that you don’t have to worry about your
+    manifest being in sync with the Nix expressions you’re installing
+    from; i.e., you don’t need to run <command>nix-pull</command> to
+    update your manifest.  It’s also more scalable because you don’t
+    need to redownload a giant manifest file every time.
+    </para>
+
+    <para>A Nix channel can provide a binary cache URL that will be
+    used automatically if you subscribe to that channel.  If you use
+    the Nixpkgs or NixOS channels
+    (<uri>http://nixos.org/channels</uri>) you automatically get the
+    cache <uri>http://cache.nixos.org</uri>.</para>
+
+    <para>Binary caches are created using <command>nix-push</command>.
+    For details on the operation and format of binary caches, see the
+    <command>nix-push</command> manpage.  More details are provided in
+    <link xlink:href="http://lists.science.uu.nl/pipermail/nix-dev/2012-September/009826.html">this
+    nix-dev posting</link>.</para>
+  </listitem>
+
+  <listitem>
+    <para>Multiple output support should now be usable.  A derivation
+    can declare that it wants to produce multiple store paths by
+    saying something like
+<programlisting>
+outputs = [ "lib" "headers" "doc" ];
+</programlisting>
+    This will cause Nix to pass the intended store path of each output
+    to the builder through the environment variables
+    <literal>lib</literal>, <literal>headers</literal> and
+    <literal>doc</literal>.  Other packages can refer to a specific
+    output by referring to
+    <literal><replaceable>pkg</replaceable>.<replaceable>output</replaceable></literal>,
+    e.g.
+<programlisting>
+buildInputs = [ pkg.lib pkg.headers ];
+</programlisting>
+    If you install a package with multiple outputs using
+    <command>nix-env</command>, each output path will be symlinked
+    into the user environment.</para>
+  </listitem>
+
+  <listitem>
+    <para>Dashes are now valid as part of identifiers and attribute
+    names.</para>
+  </listitem>
+
+  <listitem>
+    <para>The new operation <command>nix-store --repair-path</command>
+    allows corrupted or missing store paths to be repaired by
+    redownloading them.  <command>nix-store --verify --check-contents
+    --repair</command> will scan and repair all paths in the Nix
+    store.  Similarly, <command>nix-env</command>,
+    <command>nix-build</command>, <command>nix-instantiate</command>
+    and <command>nix-store --realise</command> have a
+    <option>--repair</option> flag to detect and fix bad paths by
+    rebuilding or redownloading them.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix no longer sets the immutable bit on files in the Nix
+    store.  Instead, the recommended way to guard the Nix store
+    against accidental modification on Linux is to make it a read-only
+    bind mount, like this:
+
+<screen>
+$ mount --bind /nix/store /nix/store
+$ mount -o remount,ro,bind /nix/store
+</screen>
+
+    Nix will automatically make <filename>/nix/store</filename>
+    writable as needed (using a private mount namespace) to allow
+    modifications.</para>
+  </listitem>
+
+  <listitem>
+    <para>Store optimisation (replacing identical files in the store
+    with hard links) can now be done automatically every time a path
+    is added to the store.  This is enabled by setting the
+    configuration option <literal>auto-optimise-store</literal> to
+    <literal>true</literal> (disabled by default).</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now supports <command>xz</command> compression for NARs
+    in addition to <command>bzip2</command>.  It compresses about 30%
+    better on typical archives and decompresses about twice as
+    fast.</para>
+  </listitem>
+
+  <listitem>
+    <para>Basic Nix expression evaluation profiling: setting the
+    environment variable <envar>NIX_COUNT_CALLS</envar> to

+<title>Release 1.6 (September 10, 2013)</title>
+
+<para>In addition to the usual bug fixes, this release has several new
+features:</para>
+
+<itemizedlist>
+
+  <listitem>
+    <para>The command <command>nix-build --run-env</command> has been
+    renamed to <command>nix-shell</command>.</para>
+  </listitem>
+
+  <listitem>
+    <para><command>nix-shell</command> now sources
+    <filename>$stdenv/setup</filename> <emphasis>inside</emphasis> the
+    interactive shell, rather than in a parent shell.  This ensures
+    that shell functions defined by <literal>stdenv</literal> can be
+    used in the interactive shell.</para>
+  </listitem>
+
+  <listitem>
+    <para><command>nix-shell</command> has a new flag
+    <option>--pure</option> to clear the environment, so you get an
+    environment that more closely corresponds to the “real” Nix build.
+    </para>
+  </listitem>
+
+  <listitem>
+    <para><command>nix-shell</command> now sets the shell prompt
+    (<envar>PS1</envar>) to ensure that Nix shells are distinguishable
+    from your regular shells.</para>
+  </listitem>
+
+  <listitem>
+    <para><command>nix-env</command> no longer requires a
+    <literal>*</literal> argument to match all packages, so
+    <literal>nix-env -qa</literal> is equivalent to <literal>nix-env
+    -qa '*'</literal>.</para>
+  </listitem>
+
+  <listitem>
+    <para><command>nix-env -i</command> has a new flag
+    <option>--remove-all</option> (<option>-r</option>) to remove all
+    previous packages from the profile.  This makes it easier to do
+    declarative package management similar to NixOS’s
+    <option>environment.systemPackages</option>.  For instance, if you
+    have a specification <filename>my-packages.nix</filename> like this:
+
+<programlisting>
+with import &lt;nixpkgs> {};
+[ thunderbird
+  geeqie
+  ...
+]
+</programlisting>
+
+    then after any change to this file, you can run:
+
+<screen>
+$ nix-env -f my-packages.nix -ir
+</screen>
+
+    to update your profile to match the specification.</para>
+  </listitem>
+
+  <listitem>
+    <para>The ‘<literal>with</literal>’ language construct is now more
+    lazy.  It only evaluates its argument if a variable might actually
+    refer to an attribute in the argument.  For instance, this now
+    works:
+
+<programlisting>
+let
+  pkgs = with pkgs; { foo = "old"; bar = foo; } // overrides;
+  overrides = { foo = "new"; };
+in pkgs.bar
+</programlisting>
+
+    This evaluates to <literal>"new"</literal>, while previously it
+    gave an “infinite recursion” error.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now has proper integer arithmetic operators. For
+    instance, you can write <literal>x + y</literal> instead of
+    <literal>builtins.add x y</literal>, or <literal>x &lt;
+    y</literal> instead of <literal>builtins.lessThan x y</literal>.
+    The comparison operators also work on strings.</para>
+  </listitem>
+
+  <listitem>
+    <para>On 64-bit systems, Nix integers are now 64 bits rather than
+    32 bits.</para>
+  </listitem>
+
+  <listitem>
+    <para>When using the Nix daemon, the <command>nix-daemon</command>
+    worker process now runs on the same CPU as the client, on systems
+    that support setting CPU affinity.  This gives a significant speedup
+    on some systems.</para>
+  </listitem>
+
+  <listitem>
+    <para>If a stack overflow occurs in the Nix evaluator, you now get
+    a proper error message (rather than “Segmentation fault”) on some
+    systems.</para>
+  </listitem>
+
+  <listitem>
+    <para>In addition to directories, you can now bind-mount regular
+    files in chroots through the (now misnamed) option
+    <option>build-chroot-dirs</option>.</para>
+  </listitem>
+
+</itemizedlist>

+
+  <listitem>
+    <para>Nix 1.6 accidentally changed the semantics of antiquoted

+  </listitem>
+

+    <para>Previously, Nix optimised expressions such as

+    <replaceable>expr</replaceable>.  Thus it neither checked whether
+    <replaceable>expr</replaceable> could be coerced to a string, nor
+    applied such coercions.  This meant that
+    <literal>"${123}"</literal> evaluatued to <literal>123</literal>,
+    and <literal>"${./foo}"</literal> evaluated to
+    <literal>./foo</literal> (even though
+    <literal>"${./foo} "</literal> evaluates to
+    <literal>"/nix/store/<replaceable>hash</replaceable>-foo "</literal>).
+    Nix now checks the type of antiquoted expressions and
+    applies coercions.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now shows the exact position of undefined variables.  In
+    particular, undefined variable errors in a <literal>with</literal>
+    previously didn't show <emphasis>any</emphasis> position
+    information, so this makes it a lot easier to fix such
+    errors.</para>
+  </listitem>
+
+  <listitem>
+    <para>Undefined variables are now treated consistently.
+    Previously, the <function>tryEval</function> function would catch

+    outside.  Now <function>tryEval</function> never catches undefined
+    variables.</para>
+  </listitem>
+
+  <listitem>
+    <para>Bash completion in <command>nix-shell</command> now works
+    correctly.</para>
+  </listitem>
+
+  <listitem>
+    <para>Stack traces are less verbose: they no longer show calls to
+    builtin functions and only show a single line for each derivation
+    on the call stack.</para>
+  </listitem>
+
+  <listitem>
+    <para>New built-in function: <function>builtins.typeOf</function>,

+    1G</literal> will free up to 1 gigabyte of disk space.</para>
+  </listitem>
+
+  <listitem>
+    <para><command>nix-collect-garbage</command> has a new flag
+    <option>--delete-older-than</option>
+    <replaceable>N</replaceable><literal>d</literal>, which deletes
+    all user environment generations older than
+    <replaceable>N</replaceable> days.  Likewise, <command>nix-env
+    --delete-generations</command> accepts a
+    <replaceable>N</replaceable><literal>d</literal> age limit.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now heuristically detects whether a build failure was
+    due to a disk-full condition. In that case, the build is not
+    flagged as “permanently failed”. This is mostly useful for Hydra,
+    which needs to distinguish between permanent and transient build
+    failures.</para>
+  </listitem>
+
+  <listitem>
+    <para>There is a new symbol <literal>__curPos</literal> that
+    expands to an attribute set containing its file name and line and
+    column numbers, e.g. <literal>{ file = "foo.nix"; line = 10;
+    column = 5; }</literal>.  There also is a new builtin function,
+    <varname>unsafeGetAttrPos</varname>, that returns the position of
+    an attribute.  This is used by Nixpkgs to provide location
+    information in error messages, e.g.
+
+<screen>
+$ nix-build '&lt;nixpkgs>' -A libreoffice --argstr system x86_64-darwin
+error: the package ‘libreoffice-4.0.5.2’ in ‘.../applications/office/libreoffice/default.nix:263’
+  is not supported on ‘x86_64-darwin’
+</screen>
+
+    </para>
+  </listitem>
+
+  <listitem>
+    <para>The garbage collector is now more concurrent with other Nix
+    processes because it releases certain locks earlier.</para>
+  </listitem>
+
+  <listitem>
+    <para>The binary tarball installer has been improved.  You can now
+    install Nix by running:
+
+<screen>
+$ bash &lt;(curl https://nixos.org/nix/install)
+</screen>
+
+    </para>
+  </listitem>
+
+  <listitem>
+    <para>More evaluation errors include position information. For
+    instance, selecting a missing attribute will print something like
+
+<screen>
+error: attribute `nixUnstabl' missing, at /etc/nixos/configurations/misc/eelco/mandark.nix:216:15
+</screen>
+
+    </para>
+  </listitem>
+
+  <listitem>
+    <para>The command <command>nix-setuid-helper</command> is
+    gone.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix no longer uses Automake, but instead has a
+    non-recursive, GNU Make-based build system.</para>
+  </listitem>
+
+  <listitem>
+    <para>All installed libraries now have the prefix
+    <literal>libnix</literal>.  In particular, this gets rid of
+    <literal>libutil</literal>, which could clash with libraries with
+    the same name from other packages.</para>
+  </listitem>
+
+  <listitem>
+    <para>Nix now requires a compiler that supports C++11.</para>
+  </listitem>
