Hi Pawel,
Thanks for the update.
No, the volume 2, 2014(12.2.0.36) isn’t full compatibility
with Volume 1, 2014 (12.1.0.49), because we have made the major API changes
& introduced lot of features for this release (volume 2, 2014) to improve
the user experience and provide unique API for all our controls. We will try to
avoid like these API corrections in future.
For more information, please refer the release notes for
volume 2, 2014 release.
