Incompatible Change: The shared library version of the client library
was increased to 18 to reflect ABI changes, and avoid compatibility
problems with the client library in MySQL 5.1. Note that this is an
incompatible change between 5.5.10 and earlier 5.5 versions, so client
programs that use the 5.5 client library should be recompiled against
the 5.5.10 client library.

even though we have a major new version with this release the
update is mostly backwards compatible, but please note:
- new runtime dependency opt/libaio
- new buildtime dependency cmake
- ImmoDB is now the default database engine, the supplied
/etc/my.conf still sets MyISAM as the default and skips
InnoDB. Don't reject /etc/my.cnf without inspection.
- after the upgrade fix or rejmerge /etc/my.cnf, start
the server and run mysql_upgrade to adjust the mysql
system database tables.
