News for channel 'guix'
  New `--with-configure-flag' transformation option
    commit ae11fcb84ac478dfa56d322ef08890645183a087

    The new `--with-configure-flag' package transformation option lets you pass an additional configure flag to the build system of a
    package.  For instance, here is how you would pass a flag to `cmake', the build system of the `lapack' package:

         guix build lapack \
           --with-configure-flag=lapack=-DBUILD_COMPLEX=OFF

    Run `info "(guix) Package Transformation Options"' for more info.
  Core packages updated
    commit c919bfefd98bf2e29549539b4e28e6dc2a8a6f32

    Core packages have been updated, following months of hard work by contributors.  Noteworthy package upgrades include:

       * glibc 2.35;

       * Python 3.10;

       * Perl 5.36;

       * Mesa 22;

       * GCC 11 is now used as the default compiler.

    A major highlight is the introduction of the so-called "full-source bootstrap": packages are all built starting from a 500-byte program
    called stage0, which is then used to build a higher-level interpreter, a basic Scheme interpreter and C compiler (GNU Mes), and so on,
    until GCC (the GNU Compiler Collection) is finally built.  This is a premiere and a huge step forward in terms of transparency of
    auditability.
  Linux-libre LTS kernel updated to 6.1
    commit 21564fada141bfba25d471518b293b6004244c3a

  Linux-libre LTS kernel updated to 6.1
    commit 21564fada141bfba25d471518b293b6004244c3a

    The default version of the `linux-libre-lts' kernel has been updated to the 6.1 longterm release series.
  Using Guix within `guix shell --container'
    commit 57db09aae73e3713a10c5253758d84e1046f80dc

    The `--container' (or `-C') option lets you spawn a container---an isolated software environment.  In some cases, it is useful to use
    Guix from within the container, something that is normally not possible.

    The new `--nesting' (or `-W') option lets you do exactly that: a container created with that option will let you use `guix' commands,
    including `guix shell -C', _inside_ of it.

    The example below shows how to evaluate a `guix.scm' file to build a package from within an isolated container, which is useful if
    `guix.scm' is untrusted:

         guix shell -CW -- guix build -f guix.scm

    Run `info "(guix) Invoking guix shell"' for more information.
  Linux-libre kernel updated to 6.2
    commit 0e18c5e5bcb9204c278cfc75493d3b02b746d5c3

    The default version of the linux-libre kernel has been updated to the 6.2 release series.
  New `rpm' format for the `guix pack' command
    commit 598f4c509bbfec2b983a8ee246cce0a0fe45ec7f

    RPM archives (with the .rpm file extension) can now be produced via the `guix pack --format=rpm' command, providing an alternative
    distribution path for software built with Guix.  Here is a simple example that generates an RPM archive for the `hello' package:

         guix pack --format=rpm --symlink=/usr/bin/hello=bin/hello hello

    See `info "(guix) Invoking guix pack"' for more information.
