I have Odoo Enterprise cloned via a partner's GitHub account. I no longer work with that partner, but I have an Odoo Enterprise subscription. I have access to download Odoo Enterprise from odoo.com/downloads. The resulting tar.gz file's directory structure is substantially different. Enterprise addons are mixed right in the openerp directory.
What is the recommended way for me (not managed by a partner) to keep Odoo up to date? The current method is unreasonable, given the ability of modern tools like git.
