upload_session/finish_batch

Almost certainly an internal command that is currently undocumented - you shouldn't use it unless its documented somewhere public.

I am successfully using upload_append, but I haven't noticed this remark earlier. I was looking at updating my api to the use of ulpoad_append_v2 instead of upload_append, but now there seems to be this remark that the session should be closed before 'finish_batch'. 

I now use just /finish without closing first and that works, but has there been a change?

Hi Hevak, upload_session/finish_batch will be a new endpoint, but it isn't released yet. It's referenced in the documentation for a shared error type as you saw, but you don't need to worry about using it. The existing endpoints will continue to work as expected.
