We present the various changes made to Odoo's Python framewok for version 18. Some changes aim at making the developer's life easier, like using "list" for list views, making invisible fields optional in views, detecting group restriction inconsistencies in views, and adding Python typing to the framework. We also introduced performance improvements, like grouping SQL UPDATE queries, enabling to order by, group by and aggregate non-stored related fields, and improving database workload by using read-only mirrors.
