Release Notes: The SQLStatement class was introduced as an explicit type for SQL statements. Previously, SQL statements were passed around as std::string. Implicit conversion will allow old code to work without change. Some more code cleanup and performance improvements were done. Some portability issues have been fixed so that this release was successfully tested on Solaris, Mac OS X, and Linux with various GCC compiler versions (3.3 through 4.3) and Intel's C++ compiler (v10).
