Windows binaries for Emacs 31.0.91 (pretest #2 for what will become
Emacs 31) are now available from the alpha.gnu.org FTP site (and,
soon, also from your favorite mirror).

https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-31/?C=M;O=D

# UCRT builds
As with the first pretest there are UCRT builds that especially want
testing and checking for any observable differences between our usual
(MINGW based) Windows-native Emacs executables.

# build recipie tweak
The only difference specific to these binaries since the last change
is a small change to the build recipe provided by Eli and intended
optimize further, making pretest Emacs more pleasant to use and test
with.   Here is the new/current recipe used for both the "usual"
(msys2/MINGW64) and "new" (msys2/UCRT64) based builds:

    make -j install V=1 configure="--prefix=<lpath1> \
      --disable-acl \
      --with-modules \
      --without-dbus \
      --with-native-compilation=aot \
      --without-compress-install \
      --with-tree-sitter \
      CFLAGS='-Og -gdwarf-4 -g3'" 2>&1 \
      | tee <lpath2>.log
