Support for 1.16.X cluster versions

[msidana]

According to Kubernetes documentation, some of the API groups are deprecated like extensions/v1beta1 and apps/v1beta2.
Due to this, some of the xrally tests give the error like
'extensions/v1beta1'. Is this available in api resources?

Is there any plan to add support for 1.16.X ?

The usage of extensions/v1beta1 was removed along with #46 . Is this something else?

I didn't have the latest master branch, thus the code still had extensions/v1beta1. It also means that xrally-kubernetes supports 1.16 and doesn't supports previous versions. Shouldn't it support previous versions also ?
