I am pleased to announce the release of ODB 2.3.0.



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:



* Support for database schema evolution, including automatic schema

migration, immediate and gradual data migration, as well as soft

object model changes (ability to work with multiple schema versions

using the same C++ classes).



For a quick showcase of this functionality see the Changing Persistent

Classes section in the Hello World Example chapter:



http://www.codesynthesis.com/products/odb/doc/manual.xhtml#2.9



* Support for object sections which provide the ability to split data

members of a persistent C++ class into independently loaded/updated

groups.



* Support for automatic mapping of C++11 enum classes.



A more detailed discussion of these 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++ (both C++98/03 and C++11 are supported) 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/ARM), Windows (x86/x86-64),

Mac OS X (x86), and Solaris (x86/x86-64/SPARC) with GNU g++ 4.2.x-4.8.x,

MS Visual C++ 2005, 2008, 2010, and 2012, Sun Studio 12u2, and Clang 3.x.



The currently supported database systems are MySQL, SQLite, PostgreSQL,

Oracle, and SQL Server. ODB also provides optional profiles for Boost and

Qt, which allow you to seamlessly use value types, containers, and smart

pointers from these libraries in your persistent classes.

Enjoy,

Boris
