Hello, many thanks for the advice. I never noticed the great new public API and I have extensively used private API in my code for a long time. In the future I will try to replace tmem with public API (where possible) in order to improve mainentability.
Nevertheles I may say that the private API (at least that one used in my code me) seems also to be quite stable. In many years of development very rarely I had to change my code as a consequence of a change in the gmsh library.
