* rename all debugging related command-line options and variables to start from "debug-", and made them all OFF by default. * replace "MySQL" with "MariaDB" in error messages * "Cast ... converted ... integer to it's ... complement" is now a note, not a warning * @@query_cache_strip_comments now has a session scope, not global.
