Doctype revision control

Hiii… How can I control revision of Doctypes?
Example:
When start work using ERPNext I gave all used doctypes(forms) revision number 00 and when I make any changes on these used doctypes, I am changing the revision too (like adding new custom field).
My question how can I save a copy of versions of these doctypes as a historical info?
Thanks in advance…

I think you can activate “Track Changes” on the DocType DocType :laughing:

Thanks @vjFaLk but I am looking for contorl changes of doctype it self when just customize them. Some thing related to ISO 9001 standard.

Not out of the box
