I am currently using Odoo Online Standard version 17 and I'm planning to purchase Odoo Enterprise and want to self-host it on AWS or any other cloud platform instead of using Odoo.sh. I have some key questions:

Update Management:

1. How will I be notified about new updates when self-hosting? Is there any built-in notification system within Odoo?
2. Other than manually checking GitHub repository, what are the recommended ways to stay informed about new releases and updates?

Source Code Access:
Will I get complete access to the Enterprise source code?

1. Can I make custom modifications to the Enterprise code base? If yes:
   • Are there any restrictions on code modifications?
   • How do custom changes affect the update process?
   • What's the best practice for maintaining custom changes alongside official updates?
