Hello @Dunhou,

I noticed maxon api changed every version and almost the major part of sdk change log

We are aware that this fact is disliked by especially technical artists. But the Nodes API is still under active development and probably will be for the intermediate foreseeable future. Some changes from time to time are therefore inevitable. But we usually do not just remove something, but first mark it as deprecated and then remove it one or two cycles later, giving third parties more time to adapt. For S26, GraphModelInterface::IsSelected in graph.h changed for example into this:

[[deprecated("Use GraphModelHelper static functions")]] MAXON_METHOD Result<Bool> IsSelected(const GraphNode& node);

The problem is that this information is not visible at all for Python developers and still could also be improved for C++. We are aware of the problem, and working on the quality of change notes is something we already did over the last cycles and are still doing. Mapping such information to Python is certainly something I would like to do, but my main focus was for now gathering C++ API change notes in a more consistent manner. For now, I would recommend having an eye on the C++ change notes as a Python developer. The color coded deprecated markup should make it fairly easy to find upcoming removals, see for example the 2023.2 C++ API change notes.

We are still working on improving API change notes for C++ and Python, because we are aware that it is crucial to clearly communicate our intentions with an API. I for example would like to make such information more searchable or pull it into the relevant documentary units. I.e., pull change notes also into the class, method, etc. descriptions, which are the subject of change. But that will be very hard to do with our current solutions might therefore have to wait a bit.

Cheers,
Ferdinand
