While waiting for the final release of OpenCart v1.5, all our OpenCart themes have been updated today adding support for the latest 1.4 branch update, v1.4.9.5
Since the latest OpenCart adds a new variable in the code (one that would not be set when using previous versions), to avoid any kind of warning messages, we recommend using the latest themes release only for v1.4.9.5, while sticking with the previous themes releases for any older versions of OpenCart.
