The latest LTS is upgraded from V6.6 to V12 which has been tested and deployed around world by our customers.
V12 has much more features than previous V6.6.x and stable enough to be a new LTS version. Of course, we provide at least one-year supporting service for this new version.
Previous LTS version (V6.6.x) will be kept in supporting list until end of this year (2013).
At the same time, stable version is upgraded to V13. New features will be merged into this version and V12 will not include any new feature or service.
