  12
  13 * Changes in 0.8 (since 0.7)
  14
  15 ** Package management
  16
  17 *** New visual user interface in Emacs
  18
  19 See “Emacs Interface” in the manual.
  20
  21 *** New ‘guix environment’ command to produce development environment
  22
  23 See “Invoking guix environment” in the manual.
  24
  25 *** The ‘guix import’ command can now import packages from pipy.python.org
  26
  27 See “Invoking guix import” in the manual.
  28
  29 *** New ‘guix lint’ command, for use by Guix developers
  30
  31 See “Invoking guix lint” in the manual.
  32
  33 *** Packages can now be “grafted” with replacements of their dependencies
  34
  35 See “Security Updates” in the manual.
  36
  37 *** The distribution can be extended with ‘--load-path’ or $GUIX_PACKAGE_PATH
  38
  39 This allows users to maintain their own package definitions, and make them
  40 visible to the various user interfaces.  See “Package Modules” in the manual.
  41
  42 *** ‘guix package’ better reports package upgrades
  43
  44 *** ‘guix package’ has a new ‘--switch-generation’ option
  45
  46 See “Invoking guix package” in the manual.
  47
  48 *** ‘guix-daemon’ has a new ‘--substitute-urls’ option
  49
  50 See “Invoking guix-daemon” in the manual.
  51
  52 ** GNU distribution
  53
  54 *** The stand-alone operating system now supports Linux mapped devices
  55
  56 See “Mapped Devices” in the manual.
  57
  58 *** New fields in ‘operating-system’ declarations, better documentation
  59
  60 New fields include ‘hosts-file’, ‘mapped-devices’, and ‘swap-devices’.
  61 See “operating-system Reference” in the manual.
  62
  63 *** New services: ‘dhcp-client-service’, ‘bitlbee-service’, ‘ntp-service’
  64
  65 See “Services” in the manual.
  66
  67 *** Free firmware can be loaded
  68
  69 This notably enables support for some Atheros-based WiFi devices (ath9k-htc.)
  70 See “operating-system Reference” in the manual.
  71
  72 *** ‘grub-configuration’ declarations can now specify a theme
  73
  74 See “GRUB Configuration” in the manual.
  75
  76 *** The ‘base-initrd’ now has a different signature
  77
  78 Existing uses in ‘operating-system’ declarations need to be updated.  See
  79 “Initial RAM Disk” in the manual for details.
  80
  81 *** eudev is now used by default, instead of an old udev release
  82
  83 *** ‘guix system vm’ has a new ‘--full-boot’ option
  84
  85 See “Invoking guix system” in the manual.
  86
  87 *** The ‘file’ command is now part of the package build environment
  88
  89 Autoconf-generated ‘configure’ scripts for packages using Libtool use ‘file’
  90 to determine the target ABI, notably on MIPS, hence this change.
  91
  92 ** Programming interfaces
  93
  94 *** New ‘ruby-build-system’, for Ruby packages
  95
  96 See “Build Systems” in the manual.
  97
  98 *** New ‘glib-or-gtk-build-system’, for packages using GLib schemas
  99
 100 See “Build Systems” in the manual.
 101
 102 *** ‘gnu-build-system’ has a new #:substitutable? parameter
 103
 104 This allows packagers to mark a package as requiring a local build, thus
 105 preventing it from being substituted by a pre-built binary.
 106
 107 *** ‘cmake-build-system’ has a new #:build-type parameter
 108
 109 See “Build Systems” in the manual.
 110
 111 *** The ‘supported-systems’ field of packages is used more consistently
 112
 113 This allows packagers to prevent attempts to build a package on a given
 114 architecture when that architecture is known not to be supported.  The
 115 ‘package-transitive-supported-systems’ procedure returns the intersection of
 116 the systems supported by the given package and by its dependencies.
 117
 118 *** The ‘wrap-program’ procedure can now be called multiple times
 119
 120 *** New ‘graft-derivations’ and ‘package-grafts’ procedures
 121
 122 They implement “grafts”, as described under “Security Updates” in the manual.
 123
 124 *** New “bag” intermediate representation for use by build systems
 125
 126 “Bags” are used internally as an intermediate representation between packages
 127 and derivations.  See “Build Systems” in the manual.
 128
 129 *** New (guix monad-repl) module, for monadic interaction at the REPL
 130
 131 See “The Store Monad” in the manual.
 132
 133 *** New (guix build emacs-utils) module, to facilitate building Emacs packages
 134
 135 *** New (guix tests) module, with tools used by the test suite
 136
 137 *** The internal ‘guix-register’ command now deduplicates files in store items
 138
 139 *** Several system modules moved from (guix build …) to (gnu build …)
 140
 141 Also, the (gnu build linux-boot) module has been introduced, with code
 142 typically used by initial RAM disks when booting on GNU/Linux-libre.
 143
 144 *** (guix profiles) provides a representation of package transactions
 145
 146 This factorizes code between ‘guix package’ and the Emacs user interface.
 147
 148 *** Bootstrapping packages moved to (gnu packages commencement) modules
 149 ** Native language support
 150
 151 ** Bugs fixed
 152
 153 *** ‘guix-daemon’ now really deduplicates store items by default
 154
 155 Deduplication means that identical files found in /gnu/store are stored only
 156 once, using hard links.  This feature was wrongfully disabled, and is now
 157 enabled by default.  The former ‘--disable-store-optimization’ option has been
 158 renamed to ‘--disable-deduplication’.
 159
 160 *** ‘guix-daemon’ no longer uses ‘vfork’
 161
 162 This could cause problems with ancient Linux kernel.
 163
 164 *** Fixed compilation of ‘gccgo’ (<http://bugs.gnu.org/18101>)
 165 *** 'make clean' doesn't delete os-config.tmpl (<http://bugs.gnu.org/18243>)
 166 *** Fix handling of periods by fill-paragraph (<http://bugs.gnu.org/17468>)
 167 *** Produce a top-level Info 'dir' file (<http://bugs.gnu.org/18305>)
 168 *** guix offload ignores unreachable machines (<http://bugs.gnu.org/18070>)
 169 *** guix offload: Ignore EEXIST when registering a .drv as a GC root
 170     (<http://bugs.gnu.org/18115>)
 171 *** perl-tk: Build sequentially (<http://bugs.gnu.org/18262>)
 172 *** download: Use the 'SERVER NAME' TLS extension when possible
 173     (<http://bugs.gnu.org/18526>)
 174 *** libdaemon: Add alternate source URLs (<http://bugs.gnu.org/18639>)
 175 *** icu4c: Reinstate RUNPATH on shared libraries
 176     (<http://bugs.gnu.org/18695>)
 177 *** nss-mdns: Add alternate source URLs (<http://bugs.gnu.org/18704>)
 178 *** download: Add "Accept: */*" to the HTTP headers
 179     (<http://bugs.gnu.org/18768>)
 180 *** guix-register: Do not attempt to create NIX_STORE_DIR
 181     (<http://bugs.gnu.org/18689>)
 182 *** Allow Linux-libre to find our 'modprobe' command
 183     (<http://bugs.gnu.org/18525>)
 184 *** man-pages: Build sequentially (<http://bugs.gnu.org/18701>)
 185 *** Fix intermittent test failures involving GC (<http://bugs.gnu.org/18935>)
 186 *** guix import: pypi: Gracefully handle non-existent packages
 187     (<http://bugs.gnu.org/18831>)
 188 *** Make sure the shared library has the '.so' extension
 189     (<http://bugs.gnu.org/18521>)
 190 *** pull: Use the build procedure provided by the newly-downloaded Guix.
 191     (<http://bugs.gnu.org/18534>)
 192 *** WindowMaker no longer pollutes $PATH (<http://bugs.gnu.org/18698>)
 193
 194 * Changes in 0.7 (since 0.6)
 195 ** Package management
 196 *** Binaries for mips64el-linux now available from hydra.gnu.org
 197
 198 These come in addition to the x86_64-linux and i686-linux binaries already
 199 provided, thanks to our generous donor and friendly admins.  See
 200 “Substitutes” in the manual.
 201
 202 *** ‘guix package’ has a new ‘--show’ option
 203 *** ‘guix refresh’ has a new ‘--list-dependent’ option
 204
 205 ** Programming interfaces
 206 *** New (guix gexp) module, which implements “G-expressions”
 207
 208 G-expressions are a new mechanism to embed build-side code in host-side
 209 code.  See “G-Expressions” in the manual.
 210
 211 *** (gnu system) and related modules now use G-expressions
 212
 213 This greatly simplifies code, and guarantees that build code carries
 214 references to the packages or derivations it uses.
 215
 216 *** ‘build-expression->derivation’ is deprecated in favor of G-expressions
 217 *** The (gnu system) module has been largely augmented and factorized
 218 *** New (guix build vm) module, support for virtual machine images
 219 *** New (guix build activation) module, for “system activation”
 220 *** New (guix build syscalls) module
 221 *** New (guix build install) and module for whole system installation
 222 *** New (gnu system install) module, for the installation system
 223 *** New (gnu system file-systems) module, for ‘file-system’ declarations
 224 *** New (gnu) module, which aggregates common (gnu …) modules
 225 *** ‘service’ records now have an optional ‘activate’ field
 226
 227 This allows services to specify code to run at system activation time.
 228
 229 ** GNU distribution
 230 *** An image to install the GNU system from a USB stick is provided
 231
 232 This is the first time an installation image is provided.  See “System
 233 Installation” in the manual for details.  This is work in progress as noted
 234 in “Limitations”.  Your feedback and help are welcome!
 235
 236 *** Support for more parameters in ‘operating-system’ declarations
 237
 238 Operating system declarations can now provide a list of file systems, a list
 239 of setuid programs, bootloader options, and more.  See “System Configuration”
 240 in the manual.
 241
 242 *** ‘guix system’ supports more actions
 243
 244 Newly supported actions are ‘init’, ‘build’, ‘reconfigure’, and ‘disk-image’.
 245 See “Invoking guix system” in the manual.
 246
 247 *** User accounts and groups are created at system activation time
 248 *** Virtual machine support uses para-virtualized devices
 249 *** GCC package now has an additional ‘lib’ output, for run-time support libs
 250 *** GLib package now has a separate “bin” output (<http://bugs.gnu.org/17853>)
 251 *** 134 new packages

 306 *** Synchronization and GC issues fixed in the offload hook
 307 *** (guix ftp-client) emits USER commands suitable for all servers
 308
 309 * Changes in 0.6 (since 0.5)
 310 ** Package management
 311 *** Default store directory changed to /gnu/store
 312
 313 Although it is still possible to configure Guix to use the old store
 314 directory, we recommend that you start with a fresh install to /gnu/store.
 315
 316 *** Substitutes from hydra.gnu.org must now be signed and authorized
 317 *** Support for offloading builds to other Guix machines over SSH
 318 *** New ‘guix archive’ command
 319 *** New ‘guix system’ command; it can currently build VM images
 320 *** ‘guix package’ accepts several arguments after -i, -r, and -u
 321 *** Updating a profile with ‘guix package’ is now noticeably faster
 322 *** ‘guix build’ can override a package’s source with the new ‘--with-source’

 382 *** ‘guix package --list-*’ gracefully handles EPIPE when used in a pipeline
 383 *** ‘guix package’ handles collisions between a symlink and a directory
 384     (http://bugs.gnu.org/17083)
 385 *** HTTP downloads provide a ‘User-Agent’ field (http://bugs.gnu.org/16703)
 386 *** ‘guix package’ no longer shows misleading installed package number
 387     (http://bugs.gnu.org/16484)

 392
 393 * Changes in 0.5 (since 0.4)
 394 ** Package management
 395 *** GNU package descriptions synchronized with the ‘gnumaint’ repository
 396
 397 In addition to synopses, descriptions of GNU packages are now kept in sync
 398 with the ‘gnumaint’ repository, which is the canonical place for GNU package
 399 meta-data.
 400
 401 ** Programming interfaces
 402 *** Patches are now listed as part of ‘origin’
 403
 404 The ‘origin’ form supports two new fields: ‘patches’ (list of patches), and
 405 ‘snippet’ (code snippet to modify the source.)  These are applied when running
 406 ‘guix build --source’.  See “Defining Packages” in the manual.
 407
 408 *** New (guix monads) monadic interface to operate on the store
 409
 410 See “The Store Monad” in the manual.  The (gnu system …) modules have been
 411 rewritten to use this monadic interface.
 412
 413 *** New (guix profiles) module
 414
 415 It provides an API for dealing with profiles, as with the ‘guix package’
 416 command.
 417
 418 *** New (gnu system) module
 419
 420 This module provides a generic way to describe the system’s configuration,
 421 and to instantiate it, regardless of the final medium (QEMU image, etc.)
 422 See “System Configuration” in the manual.
 423
 424 This is work in progress.  Send feedback to guix-devel@gnu.org!
 425
 426 *** ‘build-expression->derivation’ uses more parameters
 427
 428 Some positional parameters have been changed to keyword parameters.
 429 See “Derivations” in the manual.
 430
 431 ** GNU distribution
 432 *** New port to the Loongson MIPS64 processors, n32 ABI (‘mips64el-linux’)
 433
 434 Bootstrap binaries have been built for that architecture, and several
 435 Loongson-specific patches not yet available upstream have been applied to core
 436 packages.  See “GNU Distribution” and “Porting” in the manual.
 437
 438 Pre-built binaries are not yet available via hydra.gnu.org, so Guix will
 439 build from source on this platform.

 475 *** Packages are now built with GCC 4.8.2 by default (was 4.7.3)
 476
 477 ** Native language support
 478 *** New ‘sr’ (Serbian) translation
 479 *** New ‘vi’ (Vietnamese) translation
 480 *** Updated ‘pt_BR’ (Brazilian Portuguese) translation
 481 ** Bugs fixed
 482 *** ‘guix pull’ compiles Guix deterministically and correctly
 483
 484 Previously, the build environment was not cleared in between ‘compile-file’
 485 calls, leading to build errors due to Guile bug http://bugs.gnu.org/15602 .
 486
 487 *** ‘guix package’ allows removal of a specific package output
 488     (http://bugs.gnu.org/15756)
 489 *** ‘guix-daemon’ always sets umask to 022
 490     (http://lists.gnu.org/archive/html/bug-guix/2013-07/msg00033.html)
 491 *** Files referenced by environment variables are protected from GC
 492 *** Yet unbuilt packages get correctly installed (http://bugs.gnu.org/15283)
 493 *** ‘bootstrap-graph.{png,eps,pdf}’ built in srcdir (http://bugs.gnu.org/15640)
 494
 495 * Changes in 0.4 (since 0.3)
 496
 497 ** Package management
 498
 499 *** New ‘--list-generations’ and ‘--delete-generations’ options
 500
 501 The ‘guix package’ command has these two new options, which make it easier to
 502 deal with a profile’s generation.  See “Invoking guix package” in the manual.
 503
 504 *** New ‘guix-register’ program
 505
 506 This program allows the meta-data of a new store to be initialized, by
 507 copying info from an existing store.  It is mostly an internal tool.
 508
 509 ** Programming interfaces
 510
 511 *** New API to bootstrap Autotools-based packages
 512
 513 The (guix build-system gnu) has a new ‘dist-package’ procedure that takes a
 514 package object and source directory, and returns a new package object that
 515 runs ‘./bootstrap && make dist’ or anything similar.
 516
 517 *** ‘derivation’ and related procedures have a #:references-graphs parameter
 518
 519 This parameter instructs the build daemon to populate the derivation’s build
 520 tree with files containing the list of references of the given store files.
 521 This is useful to write code that copies a packages and all its dependencies
 522 to another storage device, such as a QEMU disk image.
 523
 524 *** Extended API to build a GNU system virtual machine image
 525
 526 The (gnu system vm) module has been augmented in many ways: the ‘qemu-image’
 527 procedure can now populate and initialize the image’s store; the new
 528 ‘system-qemu-image’ procedure returns a QEMU image that runs dmd as its init
 529 system, has ‘login’ running on several consoles, has a set of installed
 530 packages, and where Guix can be used.
 531
 532 New (gnu system …) modules have been added to handle the configuration of the
 533 various parts of a GNU/Linux system.  For instance, (gnu system dmd) provides
 534 support for instantiating dmd services; (gnu system linux) helps with Linux
 535 PAM configuration; and so on.
 536
 537 *** <derivation> objects supersede .drv file names in the API
 538
 539 ‘derivation’ and similar procedures no longer return two values (a
 540 <derivation> and a .drv file name); they now return a single value, which is
 541 a <derivation> object.  The <derivation> object embeds the corresponding .drv
 542 file name.  See “Derivations” in the manual for details.

 568 *** Fontconfig font search path made more convenient
 569
 570 Fontconfig, the library used by many graphical applications, such as those
 571 based on GTK+, now knows where to find the default set of fonts.  Additional
 572 fonts installed in the user profile are automatically picked up.
 573
 574 *** More GUI applications
 575
 576 The ‘emacs’ and ‘racket’ packages are now linked against GTK+.  New GTK+
 577 applications have been added (see above.)
 578
 579 *** Packaging guidelines
 580
 581 The documentation of packaging guidelines has been augmented.  See the manual
 582 under “GNU Distribution”.
 583
 584 *** Support for Python 3 along with Python 2
 585
 586 Python 3 has been added to the distribution, and Python packages that support
 587 it are now built for both Python 2 and Python 3.  See the “Python Modules”
 588 section of the manual for details.
 589
 590 ** Internationalization

 600 *** module-init-tools now builds (http://bugs.gnu.org/15182, http://bugs.gnu.org/15187)
 601 *** Hop 2.4 builds with newer Bigloo (http://bugs.gnu.org/15194)
 602
 603 * Changes in 0.3 (since 0.2)
 604
 605 ** Package management
 606
 607 *** Cross-compilation support
 608
 609 Guix can now cross-build packages.  On the command-line, this is achieved with
 610 the new ‘--target’ command-line option of ‘guix build’.  At the Scheme level,
 611 the guts of this is the ‘package-cross-derivation’ procedure.  Core packages
 612 of the distribution can already be cross-compiled.  See the manual for
 613 details.
 614
 615 *** New ‘--max-silent-time’ option for “guix build” and “guix package”
 616
 617 See the manual for details.
 618
 619 *** New ‘--fallback’ option for “guix build” and “guix package”
 620
 621 This option instructs to fall back to local builds when the substituter fails
 622 to download a substitute.
 623
 624 *** New ‘--requisites’ option for “guix gc”
 625
 626 See the manual for details.
 627
 628 *** New ‘--key-download’ option for “guix refresh”
 629
 630 See the manual for details.
 631
 632 ** Programming interfaces
 633
 634 *** New ‘package-cross-derivation’ procedure in (guix derivations)
 635
 636 See the manual for details.
 637
 638 *** New ‘%current-target-system’ SRFI-39 parameter
 639
 640 This parameter is like ‘%current-system’, but for cross-compilation.  It
 641 allows code in package definitions (such as in the ‘arguments’ field) to know
 642 whether it is being cross-compiled, and what the target system is.
 643
 644 *** New (guix hash) module; new ‘open-sha256-port’ and ‘sha256-port’ procedures
 645
 646 This improves performance of SHA256 computations.
 647

 665
 666 *** Binary packages now available for i686-linux
 667
 668 The build farm at http://hydra.gnu.org now provides 32-bit GNU/Linux binaries
 669 (i686-linux), in addition to the x86_64-linux binaries.  Both can be
 670 transparently used as substitutes for local builds on these platforms.
 671
 672 *** Debug info packages
 673
 674 Some packages now have a “debug” output containing debugging information.  The
 675 “debug” output can be used by GDB, and can be installed separately from the
 676 other outputs of the package.  See “Installing Debugging Files” in the manual.
 677
 678 *** Bootstrap binaries can be cross-compiled
 679
 680 The distribution can now be ported to new architectures (currently
 681 GNU/Linux-only) by cross-compiling the “bootstrap binaries”.  See “Porting”
 682 in the manual.
 683
 684 *** Bootstrapping documented
 685
 686 See “Bootstrapping” in the manual, for information on how the GNU
 687 distribution builds “from scratch”.
 688
 689 ** Internationalization
 690
 691 New translations: eo, pt_BR.
 692
 693 ** Bugs fixed
 694 *** “guix --help” now works when using Guile 2.0.5
 695 *** Binary substituter multi-threading and pipe issues fixed
 696
 697 These could lead to random substituter crashes while substituting a binary.
 698 See commits 0332386 and 101d9f3 for details.
 699
 700 *** Binary substituter gracefully handles lack of network connectivity
 701
 702 *** Daemon properly handles rebuilds of multiple-output derivations
 703
 704 Previously it would fail when rebuilding a multiple-output derivation when
 705 some (but not all) of its outputs were already present.  See
 706 http://lists.gnu.org/archive/html/bug-guix/2013-06/msg00038.html and
 707 https://github.com/NixOS/nix/issues/122 .
 708
 709 *** ‘guix package -i foo:out’ no longer removes other outputs of ‘foo’
 710
 711 Previously only the ‘out’ output of package ‘foo’ would be kept in the
 712 profile.
 713
 714 *** Replacement (srfi srfi-37) provided if the user’s one is broken
 715
 716 When the user’s (srfi srfi-37) is affected by http://bugs.gnu.org/13176 (Guile
 717 < 2.0.9), a replacement with the bug fix is provided.  This bug would affect
 718 command-line argument processing in some cases.
 719
 720 * Changes in 0.2 (since 0.1)
 721
 722 ** Package management
 723
 724 *** Guix commands are now sub-commands of the “guix” program
 725
 726 Instead of typing “guix-package”, one now has to type “guix package”, and so
 727 on.  This has allowed us to homogenize the user interface and initial program
 728 setup, and to allow commands to be upgradable through “guix pull”.
 729
 730 *** New “guix package --upgrade” option
 731
 732 As the name implies, this option atomically upgrades all the packages
 733 installed in a profile or the set of packages matching a given regexp.
 734 See “Invoking guix package” in the manual.
 735
 736 *** New “guix package --search” option
 737
 738 Performs a full text search in package synopses and descriptions, and returns
 739 the matching packages in recutils format.  See “Invoking guix package” in the
 740 manual, for details.
 741
 742 *** New “guix pull” command
 743
 744 The command pulls the latest version of Guix–both the package management
 745 modules and the distribution.  See the manual for details.
 746
 747 *** New binary substituter
 748
 749 The “substituter” mechanism allows pre-built binaries to be transparently
 750 downloaded instead of performing a build locally.  Currently binaries are
 751 available for x86_64 Linux-based GNU systems from http://hydra.gnu.org.  The
 752 distribution is continuously built and binaries are made available from there.
 753
 754 See http://hydra.gnu.org/jobset/gnu/master under “Job status” for the list of
 755 available binary packages.
 756
 757 *** New “guix refresh” command
 758
 759 The command is used by Guix maintainers.  It automatically updates the
 760 distribution to the latest upstream releases of GNU software.
 761
 762 *** New “guix hash” command
 763
 764 Convenience command to compute the hash of a file.  See the manual for
 765 details.
 766
 767 *** Nix daemon code updated
 768
 769 The daemon code from Nix, used by the ‘guix-daemon’ command, has been updated
 770 to current Nix ‘master’.
 771
 772 ** Programming interfaces
 773
 774 *** (guix download) now supports HTTPS, using GnuTLS
 775
 776 It allows package source tarballs to be retrieved over HTTPS.
 777
 778 *** New ‘native-search-path’ and ‘search-path’ package fields
 779
 780 Packages can define in their ‘native-search-path’ field environment variables
 781 that define search paths and need to be set for proper functioning of the
 782 package.  For instance, GCC has ‘CPATH’ and ‘LIBRARY_PATH’ in its
 783 ‘native-search-path’, Perl has ‘PERL5LIB’, Python has ‘PYTHONPATH’, etc.
 784 These environment variables are automatically set when building a package that
 785 uses one of these.
 786
 787 *** Package inputs can be a function of the target system type
 788
 789 The ‘inputs’ field of a package can now be conditional on the value of
 790 (%current-system).  This is useful for packages that take system-dependent
 791 tarballs as inputs, such as GNU/MIT Scheme.
 792
 793 *** New build systems
 794
 795 The ‘perl-build-system’, ‘python-build-system’, and ‘cmake-build-system’ have
 796 been added.  They implement the standard build systems for Perl, Python, and
 797 CMake packages.
 798
 799 *** Tools to build Linux initrds, QEMU images, and more
 800
 801 The (gnu packages linux-initrd) module provides a procedure to build a Linux
 802 initrd (“initial RAM disk”).  The initrd embeds Guile, which is used to
 803 evaluate the given expression.  The example below returns an initrd that
 804 mounts the /proc file system and starts a REPL:
 805
 806   (expression->initrd
 807     '(begin
 808        (mkdir "/proc")
 809        (mount "none" "/proc" "proc")
 810        ((@ (system repl repl) start-repl))))
 811
 812 More examples in the linux-initrd.scm file.
 813
 814 Experimental interfaces to produce and use QEMU images are provided by the
 815 (gnu system vm) module.  For instance, the
 816 ‘expression->derivation-in-linux-vm’ evaluates the given Scheme expression in
 817 a QEMU virtual machine running the Linux kernel and Guile.
 818
 819 ** GNU distribution
 820
 821 Many updates and additions have been made to the distribution.  Here are the
 822 highlights.
 823
 824 *** Major updates
 825
 826 GCC 4.7.3 (the default) and GCC 4.8.0, Binutils 2.23.2, Guile 2.0.9,
 827 Coreutils 8.20, GDB 7.6, Texinfo 5.1.
 828
 829 *** Noteworthy new packages
 830
 831 TeXLive, Xorg, GNU GRUB, GNU Parted, QEMU and QEMU-KVM, Avahi, Bigloo,
 832 CHICKEN, Scheme48, Hugs, Python, Lua, Samba.
