- It's derived from the magic database of libmagic 5.14, but with most everything not related to mime types removed. - The custom database is always used by default for mime detection, but the more verbose file type detection will fall back on the default libmagic installation's database. The result is: mime type strings are now guaranteed to be consistent across platforms, but the verbose file type descriptions are not. - The custom database gets installed in $prefix/share/bro/magic, and should even be extensible if files with new patterns are added inside the directory. - The search path for the mime magic database can be controlled via BROMAGIC environment variable. - Remove mime_desc field from ftp.log. - Stop using the mime/file type canonifier with unit tests. - libmagic >= 5.04 is now a requirement.
