Please send Guix bug reports to bug-guix@gnu.org.
+* Changes in 0.3 (since 0.2)
+
+** Package management
+*** New ‘--max-silent-time’ option for “guix build” and “guix package”
+
+See the manual for details.
+
+** Bugs fixed
+*** “guix --help” now works when using Guile 2.0.5
+*** Binary substituter multi-threading and pipe issues fixed
+
+These could lead to random substituter crashes while substituting a binary.
+See commits 0332386 and 101d9f3 for details.
+
* Changes in 0.2 (since 0.1)
** Package management
on. 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 package --upgrade” option
+
+As the name implies, this option atomically upgrades all the packages
+installed in a profile or the set of packages matching a given regexp.
+See “Invoking guix package” in the manual.
+
+*** New “guix package --search” option
+
+Performs a full text search in package synopses and descriptions, and returns
+the matching packages in recutils format. See “Invoking guix package” in the
+manual, for details.
+
*** New “guix pull” command
The command pulls the latest version of Guix–both the package management
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.
+available for x86_64 Linux-based GNU systems from http://hydra.gnu.org. The
+distribution is continuously built and binaries are made available from there.
+
+See http://hydra.gnu.org/jobset/gnu/master under “Job status” for the list of
+available binary packages.
*** New “guix refresh” command
Convenience command to compute the hash of a file. See the manual for
details.
-*** (guix download) now supports HTTPS, using GnuTLS
+*** Nix daemon code updated
-It allows package source tarballs to be retrieved over HTTPS.
+The daemon code from Nix, used by the ‘guix-daemon’ command, has been updated
+to current Nix ‘master’.
** Programming interfaces
+*** (guix download) now supports HTTPS, using GnuTLS
+
+It allows package source tarballs to be retrieved over HTTPS.
+
*** New ‘native-search-path’ and ‘search-path’ package fields
Packages can define in their ‘native-search-path’ field environment variables
been added. They implement the standard build systems for Perl, Python, and
CMake packages.
+*** Tools to build Linux initrds, QEMU images, and more
+
+The (gnu packages linux-initrd) module provides a procedure to build a Linux
+initrd (“initial RAM disk”). The initrd embeds Guile, which is used to
+evaluate the given expression. The example below returns an initrd that
+mounts the /proc file system and starts a REPL:
+
+ (expression->initrd
+ '(begin
+ (mkdir "/proc")
+ (mount "none" "/proc" "proc")
+ ((@ (system repl repl) start-repl))))
+
+More examples in the linux-initrd.scm file.
+
+Experimental interfaces to produce and use QEMU images are provided by the
+(gnu system vm) module. For instance, the
+‘expression->derivation-in-linux-vm’ evaluates the given Scheme expression in
+a QEMU virtual machine running the Linux kernel and Guile.
+
** GNU distribution
Many updates and additions have been made to the distribution. Here are the
