yes, November was the deadline to release the upgrade module. But due to some bugs and security issues, we are now planning to release the module in the second week of January.
We are continuously working on it and will update as soon as we are finished.
Please do not enable the dev mode in QloApps if you are installing it on PHP version 7.x.x as it is giving some issue during installation.
