Hi,

I am pleased to announce the release of ODB 1.4.0.

ODB is an open-source object-relational mapping (ORM) system for C++. It
allows you to persist C++ objects to a relational database without having
to deal with tables, columns, or SQL and without manually writing any of
the mapping code.

Major new features in this release:

* Qt profile providing persistence support for Qt basic types, date-time
types, smart pointers, and containers. For example:

#pragma db object
class Employee
{
...

QString first_name_;
QString last_name_;

QDate born_;

QSet<QString> emails_;
QByteArray publicKey_;

QSharedPointer<Employer> employer_;
};

* Support for non-polymorphic object inheritance including abstract base
classes.

* Automatic mapping of C++ enumerations to database ENUM or integer types.
For example, in MySQL enum color {red, green, blue}; would be mapped to
ENUM('red', 'green', 'blue').

A more detailed discussion of the new features can be found in the following
blog post:

For the complete list of new features in this version see the official
release announcement:

ODB is written in portable C++ and you should be able to use it with any
modern C++ compiler. In particular, we have tested this release on GNU/Linux
(x86/x86-64), Windows (x86/x86-64), Mac OS X, and Solaris (x86/x86-64/SPARC)
with GNU g++ 4.2.x-4.5.x, MS Visual C++ 2008 and 2010, and Sun Studio 12.
