+Subject: GNU Mes 0.23 released
+
+<#secure method=pgpmime mode=sign>
+
+We are happy to announce the release of GNU Mes 0.23, representing 125
+commits over one year by four people.
+
+Mes was ported to ARM and can now be used in the GNU Guix Reduced Binary
+Seed bootstrap as described here
+
+    https://guix.gnu.org/blog/2020/guix-further-reduces-bootstrap-seed-to-25/
+
+and now also for armhf-linux and aarch-linux.  Work to integrate this
+into Guix is ongoing: tinycc and gcc-core-2.95.3 have been built.
+
+We are excited that the Nlnet Foundation is now sponsoring this work!
+
+Enjoy,
+Janneke and Danny.
+
+* About
+
+  GNU Mes[0] is a Scheme interpreter and C compiler for bootstrapping the
+  GNU System.  Since version 0.22 it has again helped to halve the size of
+  opaque, uninspectable binary seeds that are currently being used in the
+  Reduced Binary Seed bootstrap[1] of GNU Guix[2].  The final goal is to
+  help create a full source bootstrap as part of the bootstrappable
+  builds[3] effort for UNIX-like operating systems.
+
+  The Scheme interpreter is written in ~5,000 LOC of simple C, and the C
+  compiler written in Scheme and these are mutual self-hosting.  This
+  mes.c is now being simplified to be transpiled by M2-Planet[4].
+
+  Mes has a Garbage Collector, a library of loadable Scheme modules--
+  notably Dominique Boucher's LALR[5], Pre-R6RS portable syntax-case[6]
+  with R7RS ellipsis, Matt Wette's Nyacc[7] --and test suite, just
+  enough to support a REPL and a C99 compiler: mescc.
+
+  Mes + MesCC + Mes C Library can build a bootstrappable TinyCC[8] that
+  is self-hosting.  Using this tcc and the Mes C library we now have a
+  Reduced Binary Seed bootstrap for the gnutools 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 is inspired by The Maxwell Equations of Software: LISP-1.5[9] -- John
+  McCarthy page 13, GNU Guix's source/binary packaging transparency and
+  Jeremiah Orians's stage0[10] ~500 byte self-hosting hex assembler.
+
+  We are very grateful to NLNet for sponsoring the Reduced Binary Seed
+  bootstrap[11] and the ARM port[12].

+  [*] Use a .sig file to verify that the corresponding file (without the

+  and the corresponding tarball.  Then, run a command like this:
+
+    gpg --verify mes-0.23.tar.gz.sig
+
+  If that command fails because you don't have the required public key,
+  then run this command to import it:

+
+  and rerun the 'gpg --verify' command.

+
+* NEWS
+ * Changes in 0.23 since 0.22
+ ** Core
+ *** Mes and Mes C Library can now be built with GCC 10.x.
+ ** MesCC
+ *** The Mes C Library now supports an armhf-linux bootstrap.
+ *** MesCC now supports ARM.
+ *** mini.c library was split into _exit.c, and _write.c.
+ *** When building with GCC, -lgcc is now used.
+ *** MesCC now has it's own support library libmescc.a (-lmescc).
+ *** MesCC now requires mescc-tools-0.7.0 or later for ARM.
+ *** MesCC can be now built with nyacc-1.00.2:
+ note that nyacc-1.03.0 is not (backwards) compatible.
+ *** MesCC can be built with Guile 3.0.x:
+ See https://bugs.gnu.org/43831; use guild compile -O1 with Guile 3.0.x.
+ *** MesCC now raises SIGABRT on abort, if supported.
+ ** Noteworthy bug fixes
+ *** unreadchar on EOF is now a no-op.
+ *** malloc now aligns the blocks it gives out to max_align_t.

+
+We are thrilled to announce the release of GNU Mes 0.24, representing
+222 commits over one year by four people.
+
+Mes has now been ported to M2-Planet and can be bootstrapped using
+stage0-posix[0], starting from the 357-byte hex0 binary of the
+bootstrap-seeds[1], as was promised at FOSDEM'21[2].
+
+We are exciteda that the NlNet Foundation[4] is again sponsoring this
+work!
+
+What's next?
+
+Work to integrate this so-called "Full Source Bootstrap" is happening on
+the wip-full-source-bootstrap[3] branch.  Also, full Guile compatible
+module support, and RICS-V support.
+
+Enjoy!
+
+* About
+
+  GNU Mes[5] is a Scheme interpreter and C compiler for bootstrapping
+  the GNU System.  Since version 0.22 it has again helped to halve the
+  size of opaque, uninspectable binary seeds that are currently being
+  used in the Reduced Binary Seed bootstrap[6] of GNU Guix[7].  The
+  final goal is to help create a full source bootstrap as part of the
+  bootstrappable builds[8] effort for UNIX-like operating systems.
+
+  The Scheme interpreter is written in ~5,000 LOC of simple C, and the C
+  compiler written in Scheme and these are mutual self-hosting.  Mes can
+  now be bootstrapped from M2-Planet[9] and Mescc-Tools[10].
+
+  Mes has a Garbage Collector, a library of loadable Scheme modules--
+  notably Dominique Boucher's LALR[11], Pre-R6RS portable
+  syntax-case[12] with R7RS ellipsis, Matt Wette's Nyacc[13] --and test
+  suite, just enough to support a REPL and a C99 compiler: mescc.
+
+  Mes + MesCC + Mes C Library can build a bootstrappable TinyCC[14] that
+  is self-hosting.  Using this tcc and the Mes C library we now have a
+  Reduced Binary Seed bootstrap for the gnutools 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 is inspired by The Maxwell Equations of Software: LISP-1.5[15] --
+  John McCarthy page 13, GNU Guix's source/binary packaging transparency
+  and Jeremiah Orians's stage0[16] 357-byte self-hosting hex assembler.
