• Release notes — v17

• Release notes — v19

Supported versions

18	18.0.x	v18
17	17.0.x	v17

What changed

v19 (Odoo 19)

• Group ID / Group Key are company-dependent. Each Odoo company stores its own group-account settings (in v17/v18 these were a single global value).
• View layer uses Odoo 19 list views.

v18 (Odoo 18)

• Reimbursement support — adds an Is Reimbursement option on payment registration (account.payment.register) that batches reimbursements without a partner bank, via a new payment_register model.
• View tags migrated from <tree> to <list> (Odoo 18 syntax).
• Group ID / Group Key still global.

v17 (Odoo 17)

• Baseline for the current architecture.
• Group ID / Group Key global.
• Uses <tree> views.
