it still altering history is it not?
No.
It. Is . A. Film.
And the previous film will still exist. No secret, no Stalinist rewriting of history. Just a newer version of a fictionalised film. Was history altered when the 2008 version of Funny Games was released, including some differences from the 1997 version?
No, because it is a film. The true story, of which each film is a fictionalised account, is still the true story. History has not altered.
