Little other than bug fixes to 2.3.0 in this one:
o Fixed a problem with SSQLS BLOB handling due to data lifetime
issues. const_string objects now keep a copy of their
data, not just a pointer to it. This is less efficient,
but necessary to allow SSQLS to work with BLOBs.
o Fixed many more embedded null handling problems in manip.h
o MySQL++ can now optionally reference MySQL C API headers as
in a mysql subdirectory, a common thing on *ix systems,
by defining MYSQLPP_MYSQL_HEADERS_BURIED before #including
mysql++.h.
o Restored ColData_Tmpl<T>::get_string(), removed in v2.3.0,
along with warnings in the docs saying why you don't want
to use it, and what your alternatives are.
o VC++ and MinGW builds now define HAVE_MYSQL_SSL_SET macro,
which lets you use the C API's SSL features. This assumes
your C API library does actually include them, which is
the case with the official binary releases on Windows.
o Fixed simple examples-only Makefile generation, for RPMs
