Object Compatibility Between Cumulative Updates?

Is it ok to develop objects in a later CU than the client is running?

For example, if a client is running 2016 CU8, and my development server has 2016 CU14, can I develop objects on the development server and export them for use at the client? Do the objects formats change due to CUs?

If the answer is no, it seems that separate servers must be installed on the development server for each CU in use at a client. I am hoping that is not the case of course...

I would tend to think they might change, but only actually do between certain updates. If this is the case, where can I find a list of the updates that change the object file formats?

Thanks!
