It has been a very long journey since version 3.0.0 of SOCI was released. Namely, it’s been nearly three years. The RERO philosophy didn’t quite kick in somehow, but the new SOCI 3.1.0 is finally out.
The latest package can be downloaded from here http://sourceforge.net/projects/soci/ and the complete documentation is part of the package as well as available on-line at http://soci.sourceforge.net/doc/index.html. The project web page reflects the latest changes as well http://soci.sourceforge.net/.
This new release brings all the developments that took place during the last two years and that were up to now somewhat inconveniently available only from our Git repository. At the same time it also defines the snapshot and a basis for subsequent library evolution.

On behalf of SOCI Team, I’d like to thank all users and contributors who actively helped us to bring the new release to the public. I have tried hard to list everyone in the AUTHORS file. If anyone has been omitted, it happened by mistake and please don’t hesitate to tell me.
Unfortunately, due to lack of active maintenance the Firebird backend has been removed. Also, the ODBC backend needs more love, especially testing. However, we welcome anyone who is interested in taking over the maintenance of the Firebird backend as well as helping us to test and improve the ODBC backend.
As the author of the CMake configuration, I’m strongly interested in any feedback and constructive critique. Please, feel free to post your comments to soci-users. Do you have any ideas for SOCI backends to other databases? Share it!
We are very excited about this release. It allows us to define the directions for future work. There is plenty of ideas to pursue.
