Anyone using 2.3.1, please upgrade to this one! There's a serious bug
in the change to const_string which caused data corruption.
Also, if you're using MySQL's "multi statements" with either 2.3.0 or
2.3.1, you might need to upgrade as well. There are two ways to turn
this feature on, and 2.3.0 broke one of them.
o Previous release's const_string change caused more problems
than it fixed. This release contains the real fix. :)
o New Connection::set_option() handling deals with the multi
statements option correctly again. examples/multiquery now
runs again as a result.
o Added new unit testing script, called dtest. See the
HACKERS file for details. (This tool caught the previous
two problems!)
o Squished a GCC pedantic warning. Thanks for the patch go to
Andrew Sayers.
