Old config don't compiling and need updating? This is break
compatibility and need record in UPDATING (because this place where
find information about like events).
After config updating behaivor changed? Yes. This is need also record

For restoring old beheaivor need updating /boot/loader.conf? Yes. This
is also need be documented.

Good documentation is very positive for krama :)
