Does it absolute necessary to match server api version?

[listy]

When i try to use new version client api with older server i got this error:
"Server version [4.0.api08] does not match client api version [y]"

But i guess api isn't changed much to be incompatible, can it be safely workarounded?

No, it really doesn't matter anymore. These versions were introduced when a lot of changes were being made to the interface, they really haven't changed much in years. All that really changes now is adding a keyword argument here and there and occasionally a new function. All of this would be backwards compatible. This restriction probably isn't necessary anymore.
