thanks for the update

interesting, do you have plans to update to a newer version where for
example the so called "new" UNO features are available. I mean multiple
inheritance of interfaces and "new-style" services with constructor
methods, etc.

There are some nice enhancements that can improve API's a lot and can
make API's more intuitive and easier to use. For example using a
multi-inheritance interface as a return type where always the same type
of object is returned is much easier ti understand and can reduce the
queryInterface calls a lot. Constructor methods of services can also
make the code more intuitive and better to read.
