This has allowed us to homogenize the user interface and initial program +setup, and to allow commands to be upgradable through “guix pull”. + +*** New “guix pull” command + +The command pulls the latest version of Guix–both the package management +modules and the distribution. See the manual for details. + +*** New binary substituter + +The “substituter” mechanism allows pre-built binaries to be transparently +downloaded instead of performing a build locally. Currently binaries are +available for x86_64 Linux-based GNU systems from http://hydra.gnu.org. See +the manual for details. + +*** New “guix refresh” command + +The command is used by Guix maintainers. It automatically updates the +distribution to the latest upstream releases of GNU software. + +*** New “guix hash” command + +Convenience command to compute the hash of a file. See the manual for +details. + +*** (guix download) now supports HTTPS, using GnuTLS + +It allows package source tarballs to be retrieved over HTTPS. + +** Programming interfaces + +*** New ‘native-search-path’ and ‘search-path’ package fields + +Packages can define in their ‘native-search-path’ field environment variables +that define search paths and need to be set for proper functioning of the +package. For instance, GCC has ‘CPATH’ and ‘LIBRARY_PATH’ in its +‘native-search-path’, Perl has ‘PERL5LIB’, Python has ‘PYTHONPATH’, etc. +These environment variables are automatically set when building a package that +uses one of these. + +*** Package inputs can be a function of the target system type + +The ‘inputs’ field of a package can now be conditional on the value of +(%current-system). This is useful for packages that take system-dependent +tarballs as inputs, such as GNU/MIT Scheme. + +*** New build systems + +The ‘perl-build-system’, ‘python-build-system’, and ‘cmake-build-system’ have +been added. They implement the standard build systems for Perl, Python, and +CMake packages. + +** GNU distribution + +Many updates and additions have been made to the distribution. Here are the +highlights. + +*** Major updates + +GCC 4.7.3 (the default) and GCC 4.8.0, Binutils 2.23.2, Guile 2.0.9, +Coreutils 8.20, GDB 7.6, Texinfo 5.1. + +*** Noteworthy new packages + +TeXLive 2012, Xorg, GNU Parted, QEMU and QEMU-KVM, Avahi, Python, Lua, Samba. |
