[Bertrand Garrigues]

Dear groffers,

Release candidate 1.23.0.rc1 is now available from GNU's alpha ftp.  The
version can be downloaded here:

  https://alpha.gnu.org/gnu/groff/.

To build it and install it:

  mkdir build
  cd build
  ../configure
  make -j <number of cores>
  sudo make install

To uninstall it just do 'make uninstall'.  You can also download and
build the 1.23.0.rc1 from git:

  git clone https://git.savannah.gnu.org/git/groff.git
  cd groff
  git checkout 1.23.0.rc1
  ./bootstrap
  mkdir build
  cd build
  ../configure
  make -j <number of cores>
  sudo make install

Thanks to everyone that is willing to test this version.

If you find an issue please indicate which system you are running and
provide an example or test file so that we could try to reproduce the
bug.

Regards,

Bertrand Garrigues
