[arch-dev-public] News draft: libxml2>=2.9.12-6 update may require manual intervention

[Jan Alexander Steffens (heftig)]

The libxml2 package prior to version 2.9.12-6 was missing the compiled
python modules. This has been fixed in 2.9.12-6, so the upgrade may need to
overwrite any untracked pyc files created. If you get errors like these

    libxml2:
usr/lib/python3.10/site-packages/__pycache__/drv_libxml2.cpython-310.opt-1.pyc
exists in filesystem
    libxml2:
usr/lib/python3.10/site-packages/__pycache__/drv_libxml2.cpython-310.pyc
exists in filesystem
    libxml2:
usr/lib/python3.10/site-packages/__pycache__/libxml2.cpython-310.opt-1.pyc
exists in filesystem
    libxml2:
usr/lib/python3.10/site-packages/__pycache__/libxml2.cpython-310.pyc exists
in filesystem

when updating, use

    pacman -Suy --overwrite /usr/lib/python3.10/site-packages/__pycache__/\*

to perform the upgrade.
