[arch-announce] astyle>=3.1-2 update requires manual intervention

The astyle package prior to version 3.1-2 was missing a soname link. This has been fixed in 3.1-2, so the upgrade will need to overwrite the untracked soname link created by ldconfig. If you get an error `astyle: /usr/lib/libastyle.so.3 exists in filesystem` when updating, use `pacman -Suy --overwrite usr/lib/libastyle.so.3` to perform the upgrade.
