We are happy to announce the release of GNU Mes 0.25!

Although it's been only nine months since the previous release, this
release represents 116 commits over two years by six people. This
release brings RISC-V64-linux support.

We are excited that the NLnet Foundation is sponsoring this work!

What's next?

Bringing the Full Source Bootstrap to NixOS. Full Guile compatible
module support, and support for running Gash and Gash-Utils. Support
for bootstrapping gcc-4.6.4, and a Full Source Bootstrap for
armhf-linux, and riscv64-linux.

Enjoy!

* About

GNU Mes is a Scheme interpreter and C compiler for bootstrapping the
GNU System. It has helped to decimate the number and size of binary
seeds that were used in the bootstrap of GNU Guix 1.0. Recently,
version 0.24.2 has realized the first Full Source Bootstrap for Guix
<https://guix.gnu.org/en/blog/2023/the-full-source-bootstrap-building-from-source-all-the-way-down/>.
The final goal is to help create a full source bootstrap as part of
the bootstrappable builds effort <https://bootstrappable.org> for any
UNIX-like operating system.

Mes + MesCC + Mes C Library can build a bootstrappable TinyCC
<https://gitlab.com/janneke/tinycc> that is self-hosting. Using this
bootstrappable-tcc and the Mes C library we can build an ancient
version of the GNU tools triplet: glibc-2.2.5, binutils-2.20.1,
gcc-2.95.3. This is enough to bootstrap Guix for i686-linux,
x86_64-linux, armhf-linux and aarch64-linux.

Mes was inspired by The Maxwell Equations of Software: LISP-1.5 --
John McCarthy page 13, Guix's source/binary packaging transparency and
Jeremiah Orians's Stage0 <https://github.com/oriansj/stage0>, a
~500-byte self-hosting hex assembler.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:

gpg --verify mes-0.25.tar.gz.sig

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to update
or refresh it, and then rerun the 'gpg --verify' command.

gpg --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273

Alternatively, Mes can be installed or updated using Guix:

guix pull
guix install mes
