See “Package Modules” in the manual. + +*** ‘guix package’ better reports package upgrades + +*** ‘guix package’ has a new ‘--switch-generation’ option + +See “Invoking guix package” in the manual. + +*** ‘guix-daemon’ has a new ‘--substitute-urls’ option + +See “Invoking guix-daemon” in the manual. + +** GNU distribution + +*** The stand-alone operating system now supports Linux mapped devices + +See “Mapped Devices” in the manual. + +*** New fields in ‘operating-system’ declarations, better documentation + +New fields include ‘hosts-file’, ‘mapped-devices’, and ‘swap-devices’. +See “operating-system Reference” in the manual. + +*** New services: ‘dhcp-client-service’, ‘bitlbee-service’, ‘ntp-service’ + +See “Services” in the manual. + +*** ‘grub-configuration’ declarations can now specify a theme + +See “GRUB Configuration” in the manual. + +*** The ‘base-initrd’ now has a different signature + +Existing uses in ‘operating-system’ declarations need to be updated. See +“Initial RAM Disk” in the manual for details. + +*** eudev is now used by default, instead of an old udev release + +*** ‘guix system vm’ has a new ‘--full-boot’ option + +See “Invoking guix system” in the manual. + +*** The ‘file’ command is now part of the package build environment + +Autoconf-generated ‘configure’ scripts for packages using Libtool use ‘file’ +to determine the target ABI, notably on MIPS, hence this change. + +*** Bootstrapping packages moved to (gnu packages commencement) modules + +** Programming interfaces + +*** New ‘ruby-build-system’, for Ruby packages + +See “Build Systems” in the manual. + +*** New ‘glib-or-gtk-build-system’, for packages using GLib schemas + +See “Build Systems” in the manual. + +*** ‘gnu-build-system’ has a new #:substitutable? parameter + +This allows packagers to mark a package as requiring a local build, thus +preventing it from being substituted by a pre-built binary. + +*** ‘cmake-build-system’ has a new #:build-type parameter + +See “Build Systems” in the manual. + +*** The ‘supported-systems’ field of packages is used more consistently + +This allows packagers to prevent attempts to build a package on a given +architecture when that architecture is known not to be supported. The +‘package-transitive-supported-systems’ procedure returns the intersection of +the systems supported by the given package and by its dependencies. + +*** The ‘wrap-program’ procedure can now be called multiple times + +*** New ‘graft-derivations’ and ‘package-grafts’ procedures + +They implement “grafts”, as described under “Security Updates” in the manual. + +*** New “bag” intermediate representation for use by build systems + +“Bags” are used internally as an intermediate representation between packages +and derivations.

This feature was wrongfully disabled, and is now +enabled by default. The former ‘--disable-store-optimization’ option has been +renamed to ‘--disable-deduplication’. + +*** ‘guix-daemon’ no longer uses ‘vfork’ + +This could cause problems with ancient Linux kernel. + +*** Fixed compilation of ‘gccgo’ (<http://bugs.gnu.org/18101>) +*** 'make clean' doesn't delete os-config.tmpl (<http://bugs.gnu.org/18243>) +*** Fix handling of periods by fill-paragraph (<http://bugs.gnu.org/17468>) +*** Produce a top-level Info 'dir' file (<http://bugs.gnu.org/18305>) +*** guix offload ignores unreachable machines (<http://bugs.gnu.org/18070>) +*** guix offload: Ignore EEXIST when registering a .drv as a GC root + (<http://bugs.gnu.org/18115>) +*** perl-tk: Build sequentially (<http://bugs.gnu.org/18262>) +*** download: Use the 'SERVER NAME' TLS extension when possible + (<http://bugs.gnu.org/18526>) +*** libdaemon: Add alternate source URLs (<http://bugs.gnu.org/18639>) +*** icu4c: Reinstate RUNPATH on shared libraries + (<http://bugs.gnu.org/18695>) +*** nss-mdns: Add alternate source URLs (<http://bugs.gnu.org/18704>) +*** download: Add "Accept: */*" to the HTTP headers + (<http://bugs.gnu.org/18768>) +*** guix-register: Do not attempt to create NIX_STORE_DIR + (<http://bugs.gnu.org/18689>) +*** Allow Linux-libre to find our 'modprobe' command + (<http://bugs.gnu.org/18525>) +*** man-pages: Build sequentially (<http://bugs.gnu.org/18701>) +*** Fix intermittent test failures involving GC (<http://bugs.gnu.org/18935>) +*** guix import: pypi: Gracefully handle non-existent packages + (<http://bugs.gnu.org/18831>) +*** Make sure the shared library has the '.so' extension + (<http://bugs.gnu.org/18521>) +*** pull: Use the build procedure provided by the newly-downloaded Guix. + (<http://bugs.gnu.org/18534>) + * Changes in 0.7 (since 0.6) ** Package management *** Binaries for mips64el-linux now available from hydra.gnu.org |
