I just migrated from odoo15 to odoo16 on premise database , almost all of the changes are compatible and succesful except for some custom modules , where the attribute names and methods name have changed and no longer exist on the new Odoo16 code. 

Is there a documentation in Odoo listing out all of those changes in each module? 

How should I tackle these problem?

for example: 

in Odoo15 in account.move.line' object had an attribute 'exclude_from_invoice_tab' where as in odoo16 its not there? so how do I find out what it has changed into?
